After mid-August, cotton enters the late stage of the flowering and bolling period. This period is mainly characterized by the formation of a large amount of autumn peach in the middle and upper part of the cotton field, and a large number of bolls in the field enter the internal enrichment period. During this period of time, temperature, nutrients, and moisture have a great influence on the development of seeds and fibers. Attention should be paid to the following aspects in field tubes. First, continue to control cotton aphid, cotton leafhopper and cotton bollworm, in the prevention and treatment of drugs should be used for rotation, not a long-term use of a drug. Second, strengthen water and fertilizer management in cotton fields. Pay attention to drought prevention and premature aging. This period should be filled with water and peach. For areas with poor soil moisture retention, water can be stopped at night. If the temperature is high and the frost period is late, light watering may be appropriate to delay the time of water stoppage. If the cooling rate is faster in the later period, for the high groundwater level, the soil is heavy and the cotton field is prosperous, the water must be stopped early. For the premature aging of the cotton field, foliar fertilizer should be sprayed in time, such as potassium dihydrogen phosphate, Trace Elements, etc. for extra-root fertilizer. Third, push the plant and ridge: For high density, plant higher cotton field should be in the width of the line will be two rows of cotton plants to push both sides, and lightly step on the base of cotton plant stems, so that was eight-shaped, every 5-7 days again Apply the same method to narrow lines to prevent rotten bells and promote boll boll maturation. Fourth, timely spraying ethephon. If the temperature in autumn is low, ethephon should be sprayed properly for greedy and late-maturing cotton. The time is generally around September 20, with a specific dosage of 100-200 g/mu (40% of active ingredient) and a concentration of 800-1500 kg/mu. With the use of the same, evenly spray on cotton bolls. Fifth, timely harvest. Generally, 1-2 bells of cotton plants can be harvested when fully matured.
