Cotton is usually picked once 5-7 days after batting. If the cotton fiber is picked too early, it is not fully mature, and the yield and quality will be reduced. Picking too late, cotton wool exposed to wind and sun will reduce fiber tension, pollute color and reduce cotton quality. Therefore, in the cotton batting period, fine cotton should be harvested in time to improve the quality and grade of cotton fiber. 3. Prevent rain. Mature cotton wool will be polluted by pigments in cotton seed hulls, cotton leaves and wrapped leaves after rain, which will make white cotton fibers appear yellowish, reddish and gray spots. If it rains continuously, it will cause mildew and deterioration. Therefore, it is necessary to keep abreast of the weather changes, pay attention to the weather forecast, and grab the cotton before it rains.
