High temperature and strong sunlight in cotton, but in recent periods, most parts of Shaanxi have more rainy weather, and there is a serious lack of sunshine, low temperatures, and high humidity in the cotton fields. This is extremely unfavorable to cotton production, and the shedding of the bells has increased significantly. In addition, even rainy weather caused the normal growth of cotton fibers, bolls are too small, and boll opening time delays. The following management measures should be strengthened: Strengthen pruning In time, knock down the old leaves of the lower main stem, cut the empty branches, and improve the ventilation and light transmission conditions in the field. At the same time, remove the upper buds and flowers and reduce nutrient consumption. At the same time, 98% of dilute amines 2 to 3 grams per mu for flourishing cotton fields, 98% of dilute amines 1 to 2 grams per acre for well-developed cotton fields, 98% shrinkage per acre for poor growing cotton fields. Amines 0.5 to 1.0 g, preferably before fertilization after fertilization. Picking the lower mature bolls to pick yellow bolls on the lower fruiting branches of the plants and reap ripening with ethephon solution. For cotton fields and more land and early failure blocks, apply 5 to 7.5 kilograms of urea per acre. This can also be combined with pest control for foliar spray. Insect pest comprehensive prevention and treatment for the rotten bell and sick bell, once discovered, timely picking, and bring out of the field, at any time stripping the sun, to prevent the spread of bacteria harm. For dry 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. The more severe disease can be re-irrigated every 5 to 7 days and 0.2% of phosphoric acid is used. Hydrogen Potassium solution +1% urea solution is sprayed once every 5~7 days and continuously sprayed 2~3 times.
