The light and heat conditions in the early part of this year are favorable for the growth of cotton, but low-temperature, low-light and rainy weather in recent days are extremely unfavorable to cotton growth, and the shedding of the bells is significantly increased. At the current critical period of cotton production, to seize cotton production, the following management measures should be strengthened: 1. Apply top-cover fertilizer and foliar-spraying fertilizer For field plots and premature failure plots in the cotton fields, apply urea 5-7.5 kg per 667 square meters, or combine pest control for foliar spray application. Second, a reasonable pruning and chemical control due to the recent rain more, resulting in poor ventilation and light to the cotton fields, etc., so should be pushed and ridge. At the same time, for every 667 square meters of wangchang cotton field with 98% of the 2-3 grams of condensation amines, the growing stable cotton field with 8% of 98% of the dilute amine per 667 square meters, the poor growing cotton field per 667 square meters Rice uses 98% of the 0.5-1.0 g of the dilute amine, preferably before fertilizing after fertilization. III. Integrated pest control and prevention Strengthen the control of cotton bollworm, blind cinerea, whitefly, etc., and use pesticides such as pyrethroids, organophosphorus, etc. for alternate prevention and treatment, and pay attention to the protection of natural enemies, generally after 5:00 pm. For blight and verticillium wilt, prevention should be the main method. In the early stage of disease, 500 times 25% can be used to irrigate 100 grams of liquid medicine. Each diseased strain should be irrigated by 50-100 ml. Severe disease can be interrupted by 5-7 days. Once, while using 0.2% potassium dihydrogen phosphate solution plus 1% urea solution, spray the leaves every 5-7 days and spray 2-3 times continuously.
