Cotton bud fertilization technology

After the cotton is bud, it enters the period of vegetative growth and reproductive growth, and is still dominated by vegetative growth. During this period, it is necessary to set up a shelf for the high yield of cotton. The supply of nutrients should not only meet the needs of cotton planting, but also prevent excessive fertilization and cause long cotton plants. For cotton fields with less base fertilizer, some decomposing human excrement, cake fertilizer, or a small amount of quick-acting nitrogen fertilizer can be applied in the bud stage, and deep application of ditch can be carried out to gradually decompose the fertilizer and play a role in the flowering and boll period. For fertile cotton fields with large annual fertilization, the growth of cotton plants is prosperous, and the bud period may not be applied, or it may be postponed until the initial flowering period, so that “flowers are used for peaches”. For wheat short-season cotton, because of its short growth period, the growth rate of seedlings and buds is fast, in order to promote early seedlings, in mid-July (Shenglei period), “Yugong” brand compound fertilizer is applied per acre. % (15-15-15) 25 to 30 kg.
