The best control effect was achieved by applying 24% thiamethoxam at the end of tillering, and applying 18.7% propiconazole and 43% tebuconazole (treatment 3) at 7-10 days before and during the heading stage. The yield of the plot was relatively high, at 189.4 kg. Overall, it was recommended to use 300 mL/hm² of 24% thiamethoxam during the late tillering stage of rice, and apply 750 mL/hm² of 18.7% propiconazole once every 7-10 days before the breakthrough and during the full heading period. This can effectively prevent and control the occurrence of rice false smut, and has a certain positive effect on rice safety production.

To study the effects of bio-assisted fermentation on neutral odorant components and sensory quality of Yunnan cigar tobacco, 9 exogenous bioenzyme preparations including glucoamylase (GAL type) and 3 microorganisms including Bacillus pumilus were used for auxiliary fermentation. Using sterile water treatment as a control (CK), the content of aromatic compounds was determined by gas chromatography-mass spectrometry (GC-MS) and sensory quality evaluation was conducted.

Monitoring plots of different soil types were set up in the study area to investigate the dynamic changes of soil fertility and its effects on crop biomass under conventional fertilization and non-fertilization measures. A representative monitoring plot was selected in a typical yellow soil distribution area to carry out field experiments on soil fertility cultivation technology models, such as organic fertilizer cultivation, green fertilizer return to field, and straw return to field, etc. The main factors affecting soil fertility and the key factors of soil fertility cultivation under different soil fertility cultivation technology models were studied.

By rolling or intercropping green manure crops, the organic matter and microbial content in the soil can be increased, its physical and chemical properties can be improved, and its water and fertilizer retention capacity can be enhanced; The application of green manure can promote the growth of corn, increase its grain yield, and also have a certain promoting effect on its quality traits such as amino acids and proteins. Different types of green manure have different effects on soil physical and chemical properties and corn growth. Suitable green manure crops should be selected based on soil fertility conditions, production goals, etc. to improve the yield and quality of corn.

Based on spatial syntax theory, the Depthmap 10 software was used to draw the axis model of Xiyuan Park, and 4 parameters of integration degree, selection degree, cooperation degree, and intelligibility degree were used to conduct quantitative analysis of Xiyuan Park, and the optimization strategy for its landscape was proposed. The results showed that the global integration degree and selection degree values of the landscape avenue at the Qunlu Square in the central of the park were the highest, while the integration degree values in the south and north were low. Apart from the main roads, which had high choice values, the remaining roads within the park showed relatively low choice values. The park’s synergy value was low, suggesting a lack of tight connectivity between certain spaces and the overall layout, with some local spaces appearing isolated. Additionally, the low intelligibility value implies that visitors may find it challenging to ascertain their location within the park. Drawing upon the quantitative analysis and site-specific investigations, the problems existing in the landscape nodes of the park were sorted out, and regional optimization strategies such as entrance landscape area, leisure square area and ecological leisure area were proposed. This paper can provide a reference for urban park optimization design.

To study the field control effect of 7 pesticides such as mancozeb 80%WP and chloroisobromine cyanuric acid 50%WP on peach bacterial shot hole. Peach trees were taken as the research object, and no pesticide was applied as control (CK). Two groups of pesticides combinations were designed for treatment zone I (mancozincb 80%WP 700 times + chloroisobromine cyanuric acid 50%WP 1 500 times + mesocin 3%WP 600 times + thiazolium zinc 30%SC 750 times) and treatment zone II (copper quinoline 33.5%SC 1 500 times + tiametrone 3%ME 1 500 times + tetracycin 0.3%AS 500 times + thiazolium zinc 30%SC 750 times) to carry out field control tests. The rate of diseased leaf, disease index, prevention effect of diseased leaf, and diseased finger were determined, and the safety was observed.The results showed that the rates of diseased leaves in treatment area I and II were 3.41% and 4.49%, respectively, and the disease index were 0.51 and 0.91, the control effects of diseased leaves were 71.75% and 62.80%, and the control effects of diseased fingers were 83.28% and 70.16%, respectively. The results indicated that the alternate application of chemical agents had a good effect on the prevention and control of peach bacterial shot hole. This study provides a reference for the prevention and treatment of peach bacterial shot hole.

To analyze the effect of selenium-rich yeast on the physicochemical properties and flavor of blueberry wine during fermentation, an exogenous selenium supply method was used to determine the selenium enrichment ability of 4 types of yeast, such as AG1, AG2, and LM. The yeast with the best selenium enrichment effect was selected for blueberry wine fermentation, and the physicochemical indicators such as amino acid nitrogen, total acid, and pH of the fermentation broth were measured along with the main flavor compounds during the fermentation process. The results showed that AG2 (15 mg/L) had the best selenium enrichment effect, during the fermentation of blueberry wine, the contents of amino acid nitrogen and total acid in blueberry wine increased, and the highest contents were 6.2 and 7.6 g/L on the 20th day of fermentation, respectively; pH decreased slowly at first and then tended to be stable; at the initial stage of fermentation (2-6 d), the reducing sugar content in blueberry wine decreased rapidly, and then became stable. With the extension of fermentation time, the alcohol content of fermented liquor increased first and then remained unchanged, and the highest alcohol content was 13.8 %vol on the 10th day. There were some similarities and differences in the types and relative contents of the main flavor substances in the fermentation of blueberry wine inoculated with the yeast. Both of them used isoamyl alcohol, phenyl ethanol, 2-methyl-1-butanol, and 2, 3-butanediol to exert flavor. The results provide references for further research on the mechanism of selenium enrichment in blueberry wine.

Aflatoxin B₁ (AFB₁) is a kind of Aflatoxin (AFs), which mainly exists in mouldy feed.To understand the research progress of exogenous compounds that can mitigate the toxic effects of AFB₁, this paper describes the physicochemical properties of AFs and AFB₁, as well as the metabolic detoxification process of AFB₁ in vivo, and combs out 8 exogenous compounds that can alleviate AFB₁ poisoning, such as curcumin, vitamin E and yeast selenium, and their mechanisms of action. AFs is a kind of toxin produced by Aspergillus flavus and Aspergillus parasiticus. The liver is the main target organ, which has strong carcinogenic, malformation and mutagenicity. Among them, AFB₁ is the most toxic, which can cause oxidative stress, cell apoptosis, gene mutation and immune system damage, etc. In animals, it is mainly metabolized and detoxicated by enzymes such as CYP450s. The common mechanism of action of exogenous compounds such as curcumin is to inhibit or induce the activity of metabolic enzymes in vivo, change the metabolic rate and pathway of toxins, and alleviate the oxidative stress state of animals, so as to slow down the toxic effects of AFB₁. This paper provides references for screening new detoxification drugs and clinical treatment of animal AFB₁ poisoning.
