Cotton has strong resistance to warts. According to observations, the cotton plants were flooded for 48-72 hours and the plants were basically intact after drainage. After 10 days of submergence, the leaves were completely detached, the main roots were rotted half, and the water was discharged in time for management. After 20 days, the cotton cultivars resumed growth. Still get a certain amount of production. Excluding the water flooding for a long time in time will seriously affect the cotton root activity, resulting in a large number of leaves and bud bells off. It is necessary to drain water in a timely manner as much as possible to shorten the time for collecting water in the field. Timely support Miao washing seedlings by flooding, wind cotton plant lodging, after drainage should be righting, earthing, and wash away the leaves and branches on the mud. Timely cultivation of cultivating soil by the soil after the drainage of cotton fields, soil compaction, poor ventilation, must be early cultivator to remove the compaction, combined with cultivator soil cultivation, increase soil temperature in the rhizosphere to prevent lodging. Timely fertilization of cotton fields by flooding, a large number of soil nutrient loss, coupled with weakening of the root absorption capacity, timely fertilization on cotton plants to restore growth and add knot autumn peach is very favorable. Before the growth of the cotton plants resumes growth, the foliar spraying is the main method; after the cotton plants recover, they are 10-13 cm away from the cotton plant to open up the ditch (points) for fertilization, using 10 to 15 kg of ammonium per acre or 5 to 7.5 kg of urea. . Timely Prevention of Pests and Diseases After the affected cotton plants resumed growth, the branches and leaves were young, and many early locusts were susceptible, and the larvae were susceptible to damage by cotton bollworms and cotton larvae. Therefore, to treat early, cure, and ensure every leaf must be guaranteed, every bud must fight to maximize the yield per plant. Due to the high humidity in the cotton fields, it is easy to cause bad bells, and we must strengthen prevention.
