If there is a cotton farmer, the urea or compound fertilizer will be directly scattered in the wide line of cotton during top dressing, and a layer of white or grayish chemical fertilizer will be exposed on the ground. But in fact, this method of fertilization is very uneconomical: first, the application of fertilizer is large, it will increase the concentration of soil solution, and produce reverse osmosis; second, it is extremely volatile during drought and reduces the utilization rate of fertilizer; Fertilizers are easily lost with water, which increases labor costs and costs. It should be changed to spread the hole for deep application, and the fertilizer input point should be set farther away from the root to avoid burning roots. Most of the peaches are mostly because the amount of base fertilizer applied is too large. Some farmers apply a lot of organic fertilizer and also apply a lot of nitrogen fertilizer, which causes the cotton to grow wild. Therefore, the field has large shade, less light between the plants, poor ventilation and light, and the buds are seriously detached. Even if there are peaches, they can't sit still. It is recommended to remove the excess foliage and apply a delayed plant growth regulator such as ketamine or auxin to control the growth. After autumn, a large number of cotton peaches can be combined to compensate for the loss. At the peak of cotton knots every year, there will often be some lack of cotton stamina, affecting the proportion of fruit in early autumn peach and autumn peach, cotton production must be affected. However, the effective flowering period and effective bell period of cotton are very long. At this time, if the root dressing is carried out, the yield loss can be compensated. The fertilizer that can be applied is 1% to 2% urea solution or 0.2% to 0.3% potassium dihydrogen phosphate solution or a plant growth promoter 0.01% sputum (brassinin lactone) solution. The specific operation can be sprayed 1 or 2 times according to the local cotton growth. This article URL: Cotton planting fertilization considerations!
