After this kind of cotton plant bears several cotton bolls in the middle and lower part, the upper part of the cotton plant appears the phenomenon of vegetative growth decline, such as top tip, hard hair, red stem to the top, thin and yellow leaves, which is the premature senescence of cotton plant. Premature senescence of cotton plants generally occurs in stiff soil, poor fertility and poor root growth.

With the planting of cotton in the field year by year, the phenomenon of premature senescence occurs from time to time, which has become an important reason for restricting the improvement of cotton yield and quality in the field. First, the causes of premature senility. The continuous cropping of cotton in the cotton planting area of the remaining cotton field for many years leads to the lack of organic matter in the plough layer, which can not meet the effect of continuous soil fertilizer supply. At the same time, continuous cropping caused the accumulation of bacteria in the soil and the decrease of the number of insect-resistant bacteria, which hindered the normal growth of cotton roots, thus affecting the upper growth of cotton and leading to premature senescence. two。 Cotton
