What causes cotton to prevent acute wilting after rain?

What causes cotton to prevent acute wilting after rain? Please introduce the causes of acute wilting of cotton: first, the lack of oxygen in the soil. After waterlogging, the root oxygen supply is insufficient, which suffocates the root and affects the normal absorption function of the root. The longer the suffocation time is, the more serious the root damage is. Second, improper fertilization. Excessive topdressing results in excessive concentration of soil solution after rain, which leads to reverse osmosis in cotton leaves. In order to reduce losses, it is suggested that cotton farmers should pay attention to the following measures in management: first, drainage as soon as possible. For the cotton fields with stagnant water, the water in the cotton fields should be discharged out of the fields in time after the rain, and the cotton fields with waterlogging should be broken to dry the soil moisture in time to reduce the surface humidity of the cotton fields and improve the growth environment of the cotton fields. The second is extra-root topdressing. Foliar spraying 0.2% potassium dihydrogen phosphate plus 1% urea mixture, once every 7 days, for 3 consecutive times, can improve the wilting phenomenon of cotton. It is appropriate to spray the back of the leaves after 4 o'clock in the afternoon or on cloudy days. Third, timely prevention and control of diseases and insect pests. Generally, high temperature and high humidity after rain can easily lead to the occurrence of cotton wilt, rotten boll, cotton bollworm, bug bug and other diseases and insect pests. Can be combined with extra-root topdressing for prevention and control. Click to get more cotton planting technology click to get more food crop planting technology
