Tobacco black shank is one of the major diseases in tobacco production. It has become increasingly severe due to factors such as continuous cropping and frequent introduction of new varieties, threatening the yield and quality of flue-cured tobacco. The etiological characteristics, disease symptoms, pathogenic factors, and control measures of this disease were elaborated. The pathogen of this disease belongs to the genus Phytophthora, with mycelium or chlamydospores serving as the primary infection sources. Its zoospores can directly penetrate the epidermis to infect plants. The optimal temperature for mycelial growth is 28–32 °C, and the optimal temperature for sporangium production is 24–28 °C. This disease can occur throughout the entire growth period of tobacco, with high incidence from the rosette stage to the vigorous growth stage. It mainly damages the basal stems and roots. In the seedling stage, it manifests as “damping-off”; in the field stage, it presents typical symptoms such as “mantle-like”, “bamboo shoot node-like”, and “disc-like” lesions. Pathogenic factors include overwintering of pathogens (surviving for 2–3 years, with continuous cropping exacerbating accumulation), high temperature and high humidity climates (field humidity above 80% for 3–5 consecutive days leading to disease peaks), and root-knot nematode infection (aggravating the damage). Control measures include breeding disease-resistant varieties (such as highly resistant varieties such as Zhongyan 100 and Yuyan No.2, and moderately resistant varieties such as K326 and Yunyan 85); agricultural control (rational crop rotation/intercropping with non-host crops, deep plowing and sunning, high-ridging and earthing up, drainage and humidity reduction, etc.); biological control (using antagonistic microorganisms such as Bacillus and Pseudomonas, as well as plant-derived fungicides from garlic and corktree bark); and chemical control (agents such as metalaxyl-mancozeb, mefenoxam-mancozeb, and dimethomorph). Future research should further explore its pathogenic mechanisms, accelerate the improvement of disease-resistant varieties, develop environmentally friendly biological agents, and optimize integrated prevention and control systems to adapt to different production needs.

The third to last internode of the stem was shorter, which could reduce the risk of lodging. The grain filling process of maize populations exhibit a growth pattern of slow onset rapid growth gradually slowing down, following an “S” - shaped curve; the grain filling characteristic showed a single peak curve trend, the grain filling characteristic of each treatment reached their peak around 14 days after silk emergence; maize treated with 6 500 plants/667 m² had a longer duration of active filling stage. Overall, increasing the planting density of compact maize varieties appropriately can fully unleash their potential for increased yield; the suitable planting density for the density tolerant variety Huangjinliang MY73 is 6 500 plants/667 m².

Peppermint is an important medicinal and economic crop with high value-added potential in deep processing. Menthol, its primary volatile component, possesses various biological activities. The research progress of menthol on the pharmacology, including pharmacokinetics, pharmacodynamics, pharmaceutics and toxicology were reviewed based on relevant literature. In terms of pharmacokinetics, the area under the curve (AUC) of menthol is relatively low, and the mean residence time (MRT) and elimination half-life (T_1/2) are short, indicating that it is metabolized rapidly in the body. In terms of pharmacodynamics, it exerts antibacterial effects by influencing the contents of phosphatidylcholine and other components in bacterial cell membranes; it has certain antiviral effects and enhances the immune system; it influences the formation of fungal biofilms and has good inhibitory effects on fungi such as Trichophyton and Microsporum canis; it reduces the mRNA levels of inflammatory cytokines (TNF-α, IL-6 and IL-1β) in cells and increases the activity of antioxidant enzymes such as superoxide dismutase (SOD), exerting anti-inflammatory effects; it promotes apoptosis of cancer cells and inhibits their proliferation and migration; it exerts analgesic effects by regulating calcium (Ca²⁺) and sodium (Na⁺) channels in nerve cells; and it has other pharmacological activities including antiparasitic, antioxidant and neuroregulatory effects. In pharmaceutics, menthol, as an efficient penetration enhancer, enhances the transport capacity of the blood-brain barrier, lymphatic permeability, intestinal epithelial barrier and skin permeability barrier by down-regulating the levels of tight junction proteins (ZO-1, Occludin, Claudin-5). In toxicology, the median lethal dose (LD₅₀) of this substance in rats and mice is higher than 4 000 mg/kg, indicating high safety; however, long term excessive use may cause adverse reactions such as reducing the tension of the esophageal, esophageal and gastric sphincters. This article provides a reference for the further promotion and application of menthol.

This article systematically expounded the prospects of developing the Camellia oleifera planting industry from 3 aspects: economic benefits, ecological benefits and social benefits. It introduced its biological characteristics from aspects such as botanical features, ecological habits, growth and development characteristics, reproductive ability and adaptability. On this basis, it further summarized the key points of Camellia oleifera cultivation and management techniques and conducts an in-depth analysis of its economic benefits. Tea oil had multiple uses such as food, cosmetics and medicine. The cultivation of Camellia oleifera could increase vegetation coverage and improve local climate. The related industry also promoted the adjustment of agricultural industrial structure and employment of rural labor force. This plant was an evergreen shrub or small tree of the genus Camellia in the Theaceae family. It preferred warm and humid environments, enjoyed sunlight, and had strong adaptability and stress resistance. It was widely planted in southern regions and was mainly used for extracting tea oil. The key points of cultivation and management techniques for Camellia oleifera mainly included selecting an area where the climate conditions were suitable for the growth of this plant, scientific land preparation, and selecting high quality varieties with strong disease and pest resistance and wide adaptability. The propagation of Camellia oleifera mainly included seed propagation, cutting propagation, grafting propagation, etc. Single or double row planting was adopted, with a planting density of 80 to 120 plants /667 m². The trees, shrubs, and other plants in the Camellia oleifera forest were regularly removed. The seedlings were watered moderately. Drainage was ensured during the rainy season, and organic fertilizers were applied scientifically. During the young tree stage, mainly shape the trees. During the fruiting period, prune diseased and pest-infested branches, overly dense branches and overgrown branches. Comprehensive control methods should be adopted, including agricultural control (such as removing diseased branches and leaves), biological control (such as releasing natural enemy species of pests), and chemical control.

This article provides a reference for the sustainable development of the Camellia oleifera industry.

Based on the occurrence and damage of the main rice diseases and insect pests, the comprehensive control technologies, including agricultural, biological, physical and chemical prevention and control were discussed. The primary diseases included rice blast (which infected leaves, nodes, and panicles), sheath blight (which infected basal leaf sheaths), and false smut (a panicle disease). The major pests included rice planthopper (which sucked sap), the rice leaf roller (which damaged leaves by rolling), and rice stem borers (which bored into stems). The integrated control was centered on the ecosystem and combined agricultural, biological, physical, and chemical technologies. Agricultural control involved selecting resistant varieties and implementing scientific field management; biological control generally utilized natural enemies and integrated crop-aquaculture systems; physical control often employed measures such as trapping and barrier methods; chemical control was focused on reducing application quantities and increasing efficiency by selecting low-toxicity agents. By comprehensively applying these control technologies, precise prediction and green management were achieved, which protected rice yield and quality and promoted sustainable agricultural development.

The current application of technologies in grain storage were reviewed, and a grain storage system architecture based on digital twin technology and blockchain was introduced. Current grain storage technologies were evolving toward intelligent and green development. IoT sensors enable real-time collection of multi-dimensional information such as temperature, humidity, pests, and gas concentrations. Wireless technologies like NB-IoT, LoRa, and 5G ensure efficient data transmission, while cloud platforms and AI algorithms support intelligent analysis and early warning. The grain monitoring system based on digital twin technology and blockchain is a grain condition monitoring system. This system collects and transmits grain storage environmental data in real time through the perception and transmission layers. The model layer constructs a virtual representation of the physical grain storage, enabling grain condition prediction and optimized control through multi-source data fusion and simulation. The application layer utilizes AI and big data for analysis and decision-making, and introduces blockchain technology to record the entire data process, ensuring transparency and traceability of information. Its widespread application is currently constrained by multidimensional factors such as technology, cost, collaboration, and system. The next step is to gradually build a new intelligent grain storage system through technological iteration, ecological co construction, and other means.

This study systematically explores the importance, principles, specific methods, and supporting precautions of pruning techniques for ornamental peonies. The pruning of ornamental peonies must follow 4 core principles: balanced growth coordination, ventilation and light penetration, disease and pest prevention, and aesthetic shaping. Pruning is mainly carried out in spring and autumn. In spring, it is conducted before flower bud germination, with core operations including cutting off suckers, thinning flowers and buds, and removing withered flowers. In autumn, it is implemented after leaf fall, focusing on operations such as stub cutting, main branch determination, selection and retention of flowering branches, and removal of diseased, weak branches and abnormal buds. Based on this, this paper proposes a coordinated pruning model consisting of the “three cuttings and one determination” in spring (cutting suckers, thinning flower buds, removing withered flowers, and determining main branches) and the “three removals and two cuttings” in autumn (clearing diseased and weak branches, clearing crossing branches, clearing abnormal buds, cutting unlignified shoots, and cutting redundant flowering branches). Additionally, key supporting management points are clarified, including tool selection and disinfection, water and fertilizer management after pruning, and regular plant monitoring and maintenance. This technical system can provide technical support for the standardized shaping of ornamental peony plant type, precise regulation of flowering period, and sustainable cultivation management, and has important practical value for improving landscape effects and extending the peony industry chain.

Direct seeding of rice is a cultivation method that involves sowing seeds directly in the field, eliminating the need for seedling nursery and transplanting. The efficient cultivation management techniques were summarized from aspects such as variety selection, sowing methods, pre-sowing treatments, and sowing management. In production, rice varieties suitable for local cultivation with strong lodging resistance should be selected for direct seeding ( early rice varieties like Songyazao No.1, late rice varieties like Huanghuazhan, and dual-season varieties like Meixiangzhan No.2). Wet direct seeding with broadcast sowing is predominantly used for direct seeding rice due to its labor-saving and high efficiency, while hole sowing in dry direct seeding is adopted in arid regions to enhance yield. Pre-sowing practices include weed control (using herbicides such as 10% glufosinate-ammonium), field preparation (mechanical deep plowing and subsoiling), and land leveling combined with fertilization. Pre-sowing seed treatments involve sun-drying (1–2 days), seed soaking (using 25% prochloraz emulsion), and germination acceleration (placed at 30–32°C for 1–2 days). Timely sowing is crucial (early rice in early March, late rice in mid-to-early July), with a seeding rate of 3.5–4.0 kg/667 m² for conventional rice and 3.0-3.5 kg/667 m² for hybrid rice. Weed control techniques include pre-emergence treatment (using herbicides such as 40% bensulfuron-methyl · pretilachlor) 2–4 days after sowing, post-emergence control (using herbicides like penoxsulam and bentazone) 15-20 days after sowing, and late-stage supplementary control (using herbicides such as 2-methyl-4-chloro · bentazone or manual weeding) when rice reaches the 7–8 leaf stage. In field management, timely topdressing and scientific water management based on the principle of “deep water for seedling protection, shallow water for tillering, ample water for booting, and moist field for large panicle development” are essential. Additionally, chemical control agents such as paclobutrazol should be applied 3–5 days before jointing to prevent lodging. While implementing integrated disease and pest management as in conventional rice fields, special attention should be paid to controlling sheath blight during the mid-to-late growth stages of rice. This article provides a reference for the promotion and application of high yield cultivation management techniques for direct seedling rice.

Bifenthrin·clothianidin is a new type of compound insecticide that can be used to control more than 20 pests such as Helicoverpa armigera. This study explores the properties, composition, action mechanism, and application effects of this suspension concentrate, as well as its application technologies and practices in the agricultural field, and prospects for future research. The suspension concentrate is formulated by combining two active ingredients, bifenthrin and clothianidin, with dual characteristics of rapid insecticidal activity and long-term protection. Its action mechanism includes contact toxicity, stomach toxicity, and systemic translocation: it can penetrate into the insect body either by directly contacting the insect surface (dissolving the waxy layer on the exoskeleton or through microscopic pores), enter via the insect’s mouthparts and digestive tract, or indirectly infiltrate the insect body when the pest engages in piercing-sucking feeding on plant stems and leaves treated with the insecticide, ultimately leading to insect death by poisoning. In terms of application effects, this insecticide offers advantages such as a broad insecticidal spectrum, quick-acting and long-lasting efficacy, low toxicity, safety, and environmental friendliness. It also exhibits excellent environmental and ecological safety: it is safe for crop growth, compatible with other chemical agents, has minimal impacts on aquatic organisms and beneficial organisms, and can degrade into harmless substances in soil over time. Previously, this insecticide has been used to control pests such as aphids, cutworms, thrips, and pear psylla on various crops including food crops, fruits, and vegetables, and can be applied through methods such as spraying, drip irrigation, and drenching. In the future, efforts will be made to further optimize its formulation, develop more efficient and stable dosage forms, and conduct research on environmental friendliness and precise application technologies. In summary, bifenthrin·clothianidin suspension concentrate can reduce the application rate of chemical pesticides, delay the development of pest resistance, and extend the service life of pesticides, thereby boasting broad application prospects.

The biological mechanisms underlying the invasion and spread of Solidago canadensis were elaborated, along with control strategies and advances in comprehensive utilization. Its invasive spread was attributed to several biological mechanisms, including the formation of polyploid complexes, combination of sexual and asexual reproduction, production of allelochemicals, and synergistic interactions with microorganisms. Integrated management of this invasive plant should be implemented based on its life history and invasion characteristics, combining agricultural, biological, physical, and chemical methods for comprehensive control. Agricultural control was implemented through tillage, crop rotation, plastic film mulching, and planting competitive species to suppress its growth. Bio-ecological management was carried out by introducing natural enemies or replacement plants to restore ecological diversity. Physical removal (manual uprooting, mechanical excavation) was preferably conducted during the mid-to-late growth stages, with careful attention paid to rhizome treatment to prevent regrowth. Chemical eradication was achieved using herbicides such as glyphosate, applied according to habitat-specific needs to avoid resistance development. Management was implemented in phases with multi-measure coordination, emphasizing ecological safety and sustained control. Regarding comprehensive utilization, the plant was found to be rich in active components (diterpenes, triterpenes) with anti-inflammatory and antimicrobial activities, indicating high potential for pharmaceutical development. Its high crude protein and fiber content made it suitable as quality green forage or silage for ruminants like cattle and sheep. The high fiber content also rendered it an ideal raw material for papermaking and fiberboard production, as well as for conversion into biomass energy. Through comprehensive utilization such as materialization, feed production, and substrate application, its invasive impact could be mitigated, achieving both economic and ecological benefits. At present, challenges remain in the control and utilization of this invasive plant, including accelerated spread due to human activities, high costs of existing control technologies, and technical bottlenecks in resource utilization. In the future, an integrated management system combining scientific, policy, and social efforts needs to be established. This article provides a reference for the control and resource utilization of Solidago canadensis.

The virus-free tissue culture technology using potato stem tips is able to restore variety characteristics and improve potato yield and quality, making it one of the key biotechnologies in seed potato production. The entire process of virus-free tissue culture technology using potato stem tips was systematically elaborated, and its common problems along with control strategies were summarized. The technical procedure involved pretreatment of explants, shoot tip dissection, primary culture of plantlets, virus detection, and in vitro propagation of plantlets. During the primary culture stage, the explants were sterilized and pretreated, and then cultured in a specific medium to induce the differentiation of apical meristems into plantlets. The obtained primary plantlets were subjected to virus detection using serological and molecular biological methods. After confirming the absence of viruses, the plantlets were transferred to propagation and strengthening media for multiplication. 3 major issues encountered during the tissue culture process were contamination, vitrification, and browning. Contamination, caused by bacteria, fungi, or endophytes, was prevented through strict aseptic techniques, environmental sterilization, and the addition of antibiotics or bacteriostatic agents to the culture medium. Vitrified plantlets, characterized by a translucent and fragile appearance, were primarily induced by unsuitable culture conditions or excessive subculturing, and could be mitigated by adjusting light and temperature conditions, regulating hormone concentrations, and incorporating dark culture periods. Browning, a phenomenon where wounded explants secreted brown substances leading to death, was commonly suppressed by adding anti-browning agents such as sodium thiosulfate.

The myostatin gene MSTN, a crucial regulator of muscle development, holds significant research value and application potential in livestock production. This article reviewed the research progress on the mechanism of action of the MSTN gene, its role in livestock and poultry growth, and its application in livestock and poultry breeding improvement. MSTN inhibits the proliferation and differentiation of myoblasts, thereby reducing muscle growth rate and meat yield. Its regulatory process involves multiple coordinated signaling pathways, such as modulating the expression of factors like Myf5, MyoD, and CDK2, and interacting with molecules including insulin-like growth factor-1 (IGF-1). During animal growth, MSTN regulates skeletal muscle development by suppressing both the hyperplasia and hypertrophy of muscle fibers, and it can also influence fatty acid metabolism by altering mitochondrial function in skeletal muscle. Regarding breeding applications, key SNPs have been identified within the MSTN gene in cattle, goats, pigs, and other livestock. These SNPs can serve as molecular markers for meat traits, facilitating efficient breeding programs. Utilizing individuals with MSTN mutations through crossbreeding strategies (e.g., two-way or three-way crosses) alongside precise feeding management enables the development of superior breeds with excellent characteristics. Furthermore, modern gene-editing technologies like CRISPR/Cas9 can be applied to the MSTN gene to promote muscle growth, improve meat quality, and create new livestock lines. This review provides a reference for the application of the MSTN gene in livestock and poultry genetic breeding.

Andrias davidianus as an amphibian, possesses values such as food and medicinal uses. Its breeding and cultivation techniques based on practical production practices in the Huainan area of Anhui Province, covering site selection, farming facility construction, artificial propagation, artificial cultivation, and disease prevention and control were summarized. Andrias davidianus prefer shade and dislike light, favor quiet environments, and are sensitive to disturbances; the site should be secluded with ample feed resources. Breeding ponds should be constructed in shaded and ventilated underground rooms, divided into larval ponds, juvenile ponds, adult ponds, broodstock ponds, spawning ponds, and hatching ponds. Supporting facilities such as sedimentation ponds, filtration ponds, purification ponds should also be built. For artificial propagation, broodstock should be healthy, free of injuries or diseases, and weigh at least 2 kg. In broodstock ponds, a female-to-male ratio of 3∶2 is recommended for mixed breeding or separate rearing, with a stocking density of 1 individual/m². Breeding is divided into spring cultivation (April–May), pre-spawning cultivation (June–July), and autumn cultivation (August–September). The optimal time for induced spawning is August–September, with water temperature controlled at 16–23 °C. A flow-through method is used for incubation, with a flow rate of 2 m³/h, dissolved oxygen concentration >3 mg/L, and avoidance of light exposure.Artificial cultivation is divided into three stages: larval, juvenile, and adult. The larval stage requires strict control of water temperature (10–23°C), stocking density (30–50 individuals/m²), and thorough disinfection. Juvenile cultivation emphasizes graded management (6–10 individuals/m²) and“four fixed”feeding principles (fixed time, location, quality, and quantity). For adults, feeding rates (0.3%–10%) are precisely adjusted based on water temperature.Disease prevention follows a proactive approach. For parasitic diseases (trichodinosis), formalin baths are used; bacterial diseases (furunculosis, enteritis) are treated with povidone-iodine disinfection and antibiotics; fungal infections (saprolegniasis) are managed with salt baths and metalaxyl application. This study provides a reference for the healthy cultivation of Andrias davidianus.

The research progress related to the regulation of stomatal development and movement by light was summarized. Stomata, as an important channel for the exchange of gas and water between plants and the external environment, their development and movement are regulated by various environmental factors and play a significant role in the photosynthesis of plants. Stomatal development is regulated in a coordinated manner by internal and external environmental signals of plants. There are two hypotheses for the study of stomata’s response to light: one is the direct response of stomata to light, and the other is the indirect stomatal response caused by changes in intercellular CO₂ concentration. There are two pathways for the open response of stomata to light: the guard cell-specific blue light response pathway mediated by PHOT1/PHOT2 and the red light response pathway dependent on photosynthesis. Blue light participates in signal transduction through receptors such as PHOT1 and PHOT2, triggering K⁺ ion influx and promoting stomatal opening. Red light mainly participates in stomatal response through mesophyll photosynthesis. The red light response of stomata is an indirect reaction, which is caused by the response of guard cells to the reduction of intercellular CO₂ concentration resulting from mesophyll photosynthesis. In addition, green light can inhibit the opening of stomata induced by blue light, and plant hormones can directly regulate the movement of stomata and their response to external signals.

7 plant growth regulators (0.136% gibberellin·indoleacetic acid·brassinolide WP 75.0 g/hm², 0.1% triacontanol ME 1 000 mL/hm², 0.4% kinetin AS 937.5 mL/hm², 0.000 4% enadenine·oxyenadenine SP 750 mL/hm², 4% gibberellic acid SL 500 mL/hm², 0.007 5% 14-hydroxybrassinolide AS 150 mL/hm², 2% potassium nitrophenolate AS 150 mL/hm²) were used for spray treatment at the initial stage of tea bud germination and single bud stage, respectively, with spraying water as the control (CK). The effects of tea on the growth, yield, safety and appearance quality of tea were analyzed. The results showed that the 7 plant growth regulators tested could increase germination density and had a significant regulatory effect on the germination and growth of tea buds. After the second spray, the fresh tea yield increased by 12.77% to 47.35% compared to the CK, among them, the treatment with 0.136% gibberellin·indoleacetic acid·brassinolide WP at 75.0 g/hm² showed a significant increase in tea yield. 7 plant growth regulators were found to be safe for tea plant growth, improving product appearance and quality (increased bud production, tender leaves, uniform color, thickness, and size of tea shoots and leaves), while posing no harm to beneficial arthropods such as spiders. This article provides a reference for selecting suitable plant growth regulators to promote tea growth.

The research progress on the responses of plant leaf functional traits to environmental factors such as climatic factors (light, temperature, humidity), soil factors, and topographic factors (altitude, slope direction, slope position, and slope) was reviewed. In terms of climatic factors, different light conditions can lead to significant differences in leaf functional traits such as leaf lifespan, specific leaf area, and leaf size among plants. The relationship between leaf functional traits and temperature varies among different forest stands. The water transport capacity and hydraulic structure characteristics of leaves affect the water use efficiency, growth, competition and distribution of plants. Factors such as precipitation and soil humidity content can lead to diverse differences in leaf functional traits such as leaf size, specific leaf area and vein density among different plants. In terms of soil factors, the responses of plant leaf functional traits to different soil factors are different. In terms of topographic factors, the response mechanism of leaf functional traits to altitude is different in different developmental stages of different plants. The slope direction forms a local environmental gradient by regulating factors such as light and temperature, resulting in differences in leaf functional traits such as leaf area and specific leaf area among different plants. The utilization strategies of plant resources on different slopes are different, and there are differences in the performance trends of leaf functional traits such as leaf dry matter content and specific leaf area among different plants on different slopes. The functional traits of plant leaves vary with different slopes. This article provides a reference for clarifying the response mechanism of plant leaf functional traits to the environment.

Low temperature is one of the major environmental stress factors affecting plants, exerting significant influence on photosynthetic capacity and thereby hindering plant growth and development. The impact of low temperature stress on the photosynthetic mechanisms in plant leaves was summarized, focusing on changes in cellular anatomical structure, cell membrane permeability, osmoregulatory substances, and photosynthetic carbon assimilation. In terms of cellular anatomical structure, low temperature stress may disrupt the palisade/spongy tissue ratio in mesophyll cells and damage chloroplast ultrastructure. Regarding cell membrane permeability, low temperature stress induces electrolyte leakage, along with the accumulation of malondialdehyde and reactive oxygen species, leading to membrane lipid peroxidation. Plants counteract this by enhancing the activity of antioxidant enzymes such as superoxide dismutase (SOD) to maintain ROS homeostasis. Concerning osmoregulatory substances, low temperature stress triggers the dynamic accumulation of proline, soluble sugars, and proteins to sustain photosynthetic performance. In photosynthetic carbon assimilation, low temperature stress reduces chlorophyll content and the activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), altering key photosynthetic parameters such as net photosynthetic rate (Pn) and intercellular CO₂ concentration (Ci). Phosphoenolpyruvate carboxylase (PEPC) compensates for the decline in Rubisco activity by fixing low-concentration CO₂, thereby mitigating photosynthetic losses. In conclusion, this article provides a reference for analyzing the mechanism of plants’ response to low temperatures and improving the photosynthetic performance of plant leaves under low temperature stress conditions.

Porcine reproductive and respiratory syndrome (PRRS) is a contagious disease caused by the porcine reproductive and respiratory syndrome virus (PRRSV), which has a negative impact on the sustainable and healthy development of the pig industry. Developing regional purification is an effective way to control PRRS. This article systematically discusses the characteristics of PRRSV, the current status of PRRS prevention and control, and the research progress of PRRS purification. PRRSV is an enveloped spherical single-stranded positive-sense RNA virus with strong mutation and recombination ability, diverse and complex genetic background, and both antibody-dependent enhancement and persistent infection characteristics, making its comprehensive prevention and control difficult. Currently, common prevention and control measures include vaccination and drug treatment. Inactivated vaccines, attenuated vaccines, and new vaccines (subunit vaccines, nucleic acid/mRNA vaccines, etc.) can all effectively reduce the risk of PRRSV infection. Natural compounds such as dicoumarol and morin C, as well as Chinese herbal extracts such as Scutellaria baicalensis polysaccharides and Isatis indigotica polysaccharides, all have anti-PRRSV effects. Implementing regional purification of PRRS is an important means to control PRRSV. Currently, most pig farms are actively exploring the establishment of PRRS purification models for large-scale farms, and the number of successfully purified PRRS farms is increasing year by year. PRRS regional purification includes improving the biosecurity system through measures such as physical isolation, personnel control, material disinfection, and harmless treatment; selecting appropriate purification strategies such as thorough depopulation and repopulation, testing and culling, and closed purification, while also supplemented by regular and continuous testing to ensure and consolidate the purification results. This article provides a reference for the prevention and control and purification of PRRS.

Maize intercropping mode was recognized as an important technical measure to address arable land constraints and enhance the land utilization. The regulatory effects of maize intercropping with other crops including soybean on farmland ecology and agricultural production were summarized, and key considerations for intercropping were analyzed. Through spatiotemporal niche complementarity to enhance land use efficiency. The structure of soil microbial communities was improved (increased bacterial diversity and regulated fungal communities), thereby strengthening soil fertility and ecological functions. The tall maize stalks provided natural shading for shade-preferring crops (Polygonatum sibiricum, Amorphophallus konjac), regulating micro environmental humidity and light conditions. Nutrient accumulation in crops was promoted (increased crude protein in soybeans, enhanced heavy metal enrichment in Sedum alfredii), leading to improved quality. Suitable crop varieties were selected based on their characteristics, and field management was optimized, including rational planting density (adjusting row spacing to reduce shading effects), improved water and fertilizer management, and pest control (utilizing crop interactions to suppress pests). This study provided a reference for promoting the application of maize intercropping with other crops.

The genetic characteristics and types of rice dwarfism were systematically analyzed, the role of plant hormones was examined in this process, the ideal plant architecture for dwarf breeding was discussed, and prospects for future research directions were provided. Rice plant height determined jointly by the number and length of internodes, was identified as a key trait affecting lodging resistance and yield. Dwarfing mutants in rice types were diverse and could be classified inter-node shortening mode into categories such as d6-type and dm-type. Currently, plant height was categorized into tall, semi-dwarf, and dwarf based on height, though the distinction between semi-dwarf and dwarf remained to be clarified, reflecting the complexity of the underlying genetic mechanisms. Dwarfism was primarily associated with deficiencies in the metabolism or signal transduction of 3 types of hormones: gibberellin (GA), brassinosteroid (BR), and strigolactone (SL). Among these, GA and BR were directly involved in regulating internode elongation, and mutations in their related genes led to dwarfism. In contrast, SL synthetic gene mutations resulted in dwarfism along with increased tillering. A total of 36 major dwarf genes (sd1, d18, and etc.) had been cloned, providing important genetic resources for lodging-resistant breeding. The development of rice varieties with high lodging resistance, yield potential, and suitability for mechanized production had become a major objective in modern breeding. Progress in rice dwarf breeding was expected to be effectively advanced through in-depth research on the gene function, genetic diversity, and key gene networks of rice dwarfing mutants, combined with modern technologies such as gene editing and phenomics. This review provides a reference for the selection and improvement of rice varieties.

As an important food crop, foxtail millet can be cultivated in arid and saline alkali and other areas. The effects of abiotic stress were summarized, such as water, temperature, saline-alkali, and heavy metals on this crop. Water stress can affect the germination rate and yield formation of seeds, and under drought stress, plants usually close their stomata to maintain water balance within the cells. Saline-alkali stress can inhibit the growth and development of plants, resulting in restricted root growth, impaired photosynthesis, and damage to the antioxidant system. Temperature stress can cause changes in the plant morphology of foxtail millet, high temperature stress results in the production of empty grains, a decrease in the number of grains per ear, and a reduction in thousand grain weight, low temperature stress leads to impaired photosynthesis, reduced yield, and decreased quality. Heavy metal stress (such as cadmium, lead, etc.) has a significant impact on the growth, development, and yield formation of foxtail millet, and has toxic effects on its antioxidant system and metabolic regulation. In production, the stress resistance of foxtail millet can be enhanced by breeding stress resistant varieties and adjusting field management measures. This article provides a reference for promoting the research on stress resistant breeding of foxtail millet.
