The first is to figure out the pattern of fertilizer requirement of cotton. Cotton is one of the crops requiring large amount of fertilizer, but the required fertilizer at the seedling and bud stage accounts for only 20% to 30% of the total required fertilizer, and a large number of fertilizers are needed from flowering to bell-mouthing. Therefore, the more appropriate fertilization experience should be: at the end of the fertility foot, Miao Fei speed, bud stable, flower bell fat, Pu Shi peach fertilizer. Nitrogen, phosphorus, potassium fertilization ratio should be 1:0.3:1.
The second is to formulate base fertilizers where conditions are available. Organic fertilizers should be used as the main ingredient. Appropriate amounts of phosphorus and potassium fertilizers should be used. The organic fertilizer produced by the farmers should be applied in an amount of about 4,000 kilograms per mu, plus 25 kg of phosphate fertilizer and 15 kg of potassium fertilizer. . The second is the application of inorganic fertilizer, should be based on high-efficiency compound fertilizer, high content of 25 kg per acre, the content of about 50 kg per acre, and with a potash 10 kg, 0.4 kg of boron, zinc fertilizer 0.5 kg. The third is the use of hole transplanting seedlings, after fertilization with fine soil isolation, and then planted seedlings.
Third, the rapid application of Miaofei fertilizer at the foot of the cotton field, the application of a Miao Fei, the base fertilizer shortage of cotton fields, seedlings should be applied twice top dressing, the first application of urea 5 kg per mu, the second application of urea per acre 8 ~ 10 kg, 25 kg of ammonium bicarbonate can also be applied, or apply water to excrete seedlings. Seedlings should be highlighted with quick-effect fertilizers.
