Fertilizer can be supplemented by a combination of rhizosphere fertilization and foliar spray fertilizer, mainly based on nitrogen and potassium fertilizers, and phosphate fertilizer is appropriately applied in phosphorus-deficient soil. According to the high cotton production requirements, it is advisable to apply 7.5 kg of urea and 7.5 kg of potash in the cotton field; fertile oysters and cotton fields with more organic fertilizers and signs of prosperous growth should control the amount of nitrogen fertilizer; When applying nitrogen fertilizer, potassium fertilizer and phosphate fertilizer can be added to consume excess nitrogen. After the topping of cotton, supplementing fertilizer is not an optional work, but an important measure related to the level of cotton production.
