In the middle and lower reaches of the Yangtze River, the use of nitrogen and phosphate fertilizers is high, organic fertilizers are used insufficiently, some of the soils in the cotton fields are lack of elements such as potassium, boron, zinc, etc. Organic fertilizers should be added, and the organic and inorganic phases should be combined. According to soil fertility status and fertilizer effect response, Appropriately reduce the amount of nitrogen and phosphorus fertilizers to stabilize the amount of potash fertilizer; Boron and zinc in cotton soil, should be based on the application of boron and zinc fertilizers, and pay attention to the application of boron fertilizer and zinc fertilizer; seedlings transplanted cotton fields, phosphorus and potassium fertilizer using acupuncture Or methods such as applying concentrated application; fertilization combined with high yield and good quality cultivation techniques. Under the condition of 90-110 kilograms of lint per mu, 2000 mu of organic fertilizer is applied per mu, 16-18 kg of pure nitrogen, 4-6 kg of phosphorus pentoxide, and 8-10 kg of potassium oxide. In the cotton fields lacking boron and zinc, 1 kg of borax and 1.5 kg of zinc sulfate were applied per mu. 25-30% of nitrogen fertilizer application, 25%-30% of nitrogen fertilizer is applied at the initial flowering stage and flowering stage, and 15%-20% nitrogen fertilizer is applied at the boll stage. Phosphorus all basis. Potash 60% base application, 40% in the initial flowering period.
