Cotton enters the critical period of flowering and bolling, and reproductive growth is the main focus. This is the most vigorous period of growth and the peak period of fertilizer and water demand in the life of cotton, and it is also a critical period for the formation of yield and quality. Cotton management should focus on the number of bolls and the increase in boll weight, promote the transfer of nutrients to the bolls, and produce more peaches. 1. Spraying foliar fertilizer: This period is a period of reproductive growth, and water and fertilizer management should be strengthened to ensure that the cotton plants are not prosperous. Flooding and fertilizing are strictly prohibited, causing secondary growth of cotton, resulting in ineffective consumption of nutrients, and affecting single boll weight and cotton grade. 2. Pruning and branching: For cotton fields with prosperous growth, luxuriant branches and poor ventilation and light conditions, pruning measures should be taken in time, and the lower leaves without bells and part of the new leaves produced by secondary growth should be removed in time, which is beneficial to Reduce the degree of cotton field canopy, increase the amount of light received by the middle and lower bolls, promote the development of bolls, and reduce boll rotten. 3. Watering: During this period, the cotton plants are sensitive to water response, such as water imbalance and metabolic obstruction, which will cause buds to fall off, cause premature aging, and affect the final yield. Watering should be carried out according to the local climate and cotton growth. 4. Prevention of pests: Red spiders, Aphididae, Lygus and other hazards are prone to occur in the middle and late stages of cotton. Most of the red spiders and Aphididae occur in spots, and spot prevention and control are advocated, which can reduce the cost of control and avoid killing natural enemies. , Destroy the ecological balance.
