1. Rational control. For the buddhist cotton fields to focus on doing a good job of chemical control, 3-5 grams per mu reduction, can effectively control the bud sprouting and excessive elongation of the upper fruit branches, enhance the ventilation and light in the lower part. 2. Leaf spray fertilizer. Spraying 1%-2% urea water to supplement nitrogen; spraying 0.2%-0.3% or 1%-2% superphosphate calcium leachate plus 1%-2% potassium chloride leachate to supplement phosphorus and potassium; spraying 0.1% - 0.2% manganese sulfate supplements manganese; spray 0.3% ferrous sulfate to supplement iron; spray 0.1%-0.2% magnesium sulfate to supplement magnesium. Foliar spray is usually sprayed every 5-7 days, and sprayed 2-3 times in order to spray the leaves to the desired drip. 3. Take effective measures to reduce the humidity of the cotton field and improve the ventilation and light transmission. It can take 4.5-8 cm of shallow cultivator after rain and reduce the humidity in the field. To reduce canopy closure, the lower old leaves, yellow leaves, diseased leaves, empty fruit branches and empty trees should be promptly removed and brought out of the field for centralized treatment to eliminate some of the germs and eggs. The severely closed land should also be pushed and ridged. 4. Prevent disease. The most effective agents for preventing Verticillium wilt are chitin, ethyl allicin (or Formami) plus hymexazol, trichloroisocyanuric acid (or Greenhenge No. 6), etc. The above agents should be used alternately, and the disease prevention can be combined with insect pest control. Together with the spraying of foliar fertilizer to reduce the field labor intensity and reduce the humidity in the field, mu liquid volume 40-50 kg; 70% mancozeb 800-1000 times spray can be used to prevent keratoses and lenticular Diseases and other diseases.
