Analysis of Key Technical Points for Fine Cotton Management in August
1. For cotton fields showing signs of premature decline, promptly apply boll fertilizer to prevent premature aging of cotton and encourage more boll setting; for cotton fields that set many bolls in the early stage, in order to meet the nutrient needs of a large number of bolls and increase boll weight, apply top-cover fertilizer; for dry parts of the field, foliar fertilizer spraying can be mixed with New High-Lipid Film for use together, which can improve the utilization of the effective ingredients of the fertilizer and pesticide.
2. August is the peak boll-setting period for cotton. At this time the temperature is still very high and the light is strong, so water consumption is relatively large, but the cotton plants will not suffer drought. Watering should be flexible according to the specific condition of the cotton plants, and care should be taken to avoid standing water in the cotton field and rotten bolls. At the same time, spraying New High-Lipid Film can protect the moisture of the cotton seedlings from transpiration, providing sun protection and drought resistance.
3. Spray Promoter King No. 3 cotton topping agent on the cotton growing tips to replace manual topping. It can inhibit excessive vegetative growth of cotton and transform growth nutrients into reproductive nutrients. At the same time, it can thicken the nutrient transport vessels of cotton bolls, protect bolls and squares, accelerate the cyclic formation of buds, and improve fiber quality.
4. Common cotton pests in August include cotton bollworm, tobacco cutworm, red spider mite, and others. Targeted insecticides should be sprayed promptly for control, and when spraying, focus on the undersides of the leaves.
