How to fertilize cotton scientifically? Remember these seven key points
1. Base the fertilization mainly on organic fertilizer and apply sufficient base fertilizer. When preparing the soil, promptly spray a disinfectant plus 800-fold Xingaozhimo solution to disinfect the soil, and apply sufficient base fertilizer, applying 2000-3000 kg of farmyard manure per mu, to improve the root system's ability to absorb nutrients, activate the soil, prevent compaction, and maintain the ecological balance in the rhizosphere. 2. Reduce the application of diammonium phosphate. Nitrogen, phosphorus, and potassium ternary compound fertilizer should be used, or 40 kg of a 15-15-15 nitrogen, phosphorus, and potassium compound fertilizer can be used as base fertilizer. When using compound fertilizer, combine it with spraying

Five key points to remember when spraying foliar fertilizer on cotton
Cotton leaves are the most important nutritional organs of the cotton plant, possessing four functions: photosynthesis, respiration, transpiration and absorption. By making use of their absorption and photosynthesis, targeted foliar spraying of fertilizer can promote steady plant growth, strengthen resistance to disease, pests, drought and premature aging, regulate vegetative and reproductive growth, and greatly increase yield and quality. 1. Spray type: scientifically choose the foliar fertilizer according to the cotton's growth vigor; for excessively vigorous cotton seedlings, spray a 0.3%-0.4% potassium dihydrogen phosphate solution or a 2% borax solution

If the local pest infestation at the wheat seedling stage is very mild and the disease occurrence is severe, only a fungicide seed dressing is needed, and no insecticide is necessary; if pests and diseases occur together, both an insecticide seed dressing and a fungicide seed dressing should be used; if
