According to the soil fertility conditions, the fertilization principle should be used to reduce the amount of nitrogen and phosphorus fertilizers; increase the application of organic fertilizers and promote organic and inorganic cooperation; according to the potassium status of cotton fields, apply potassium fertilizer efficiently, pay attention to the combined application of boron and zinc; The proportion of nitrogen fertilizer applied in the middle growth period; fertilizer application should be combined with high-yield and high-quality cultivation techniques.
Fertilization Recommendations Under the condition of 70-90 kg of lint per mu, the total amount of fertilization is: 2000 kg of high-quality farmyard manure, 11-13 kg of nitrogen fertilizer, 5-7 kg of phosphate fertilizer, and 5-7 kg of potassium fertilizer. For cotton fields lacking boron and zinc, pay attention to the application of boron and zinc micro-fertilizer.
35% to 40% of nitrogen fertilizer is used as base fertilizer, 35% to 40% is used in the initial flowering period, 15% to 20% is used in the flowering period; all the phosphate fertilizer is used as the base fertilizer; all the potassium fertilizer is used as the base fertilizer or the base chase (the initial flowering period). half. Starting from the flowering period, the cotton field with weak growth will be sprayed with 0.5%-1.0% urea and 0.3%-0.5% potassium dihydrogen phosphate solution 50-75 kg/time, and sprayed every 7-10 days. Spray continuously for 2 to 3 times.
