How should cotton be managed well in the middle and late stages?
How should cotton be managed well in the middle and late stages? Please introduce the management methods. In the middle and late stages, cotton can be managed by referring to the following methods: 1. Management during the flowering and boll-setting stage (1) Apply flowering and boll-setting fertilizer heavily and apply topping fertilizer. Cotton generally flowers around July 10. Fertilization during the flowering and boll-setting stage generally accounts for 50% of the topdressing amount during the growth period and can be appropriately advanced, applying as soon as flowers appear (July 10-15). On the basis of sufficient basal fertilizer or base fertilizer applied earlier, apply 40-45 kg per mu of compound fertilizer containing 15% each of nitrogen, phosphorus, and potassium, or 15-20 kg of urea, 15-20 kg of diammonium phosphate, and 10-15 kg of potassium chloride, or apply a formula fertilizer with the same content of nitrogen, phosphorus, and potassium. In cotton fields where flowering and boll-setting fertilizer is insufficient or there is a trend of fertilizer deficiency during the full flowering and boll-setting stage, applying topping fertilizer is beneficial for retaining summer bolls, increasing autumn bolls, and preventing premature senescence. In early August, apply 10-15 kg of urea as topdressing, no later than mid-August. In high-yield cotton fields, after the full boll stage, the root absorption capacity declines. In cotton fields with a trend of fertilizer deficiency, spray 300-500 times dilution (or 0.3-0.5 jin per mu) of potassium dihydrogen phosphate, or 15 ml of Lüzhi Feng (Shuofeng 481), or 10 ml of Duoxiao Fengchan Ling, and other plant growth regulators or foliar fertilizers, mixed with 30 kg of water, and spray 1-2 times. This has an obvious effect on increasing boll weight. (2) Irrigate in drought and drain in waterlogging. During the flowering and boll-setting stage, cotton is sensitive to water and is neither tolerant of drought nor waterlogging. Therefore, it is necessary to promptly meet the large water consumption demand of cotton fields. In high-yield cotton fields, as long as there is no rain for 7-10 days, irrigation should be carried out promptly. In general cotton fields, if the top leaves of the cotton plants show wilting at noon, they should be watered. When rainfall is heavy, drainage should be carried out promptly. (3) Intertillage and hilling. Before the cotton field closes in the early flowering stage, intertillage and hilling should be combined. This is beneficial for irrigation during drought and drainage during waterlogging in the full flowering and boll-setting period and helps prevent lodging in the later stage of high-yield fields. (4) Pruning. Top the plants early at the appropriate time, generally from July 15-20, and finish before July 25. Tip the side branches around August 10, no later than August 15. For row spacing above 1.1 m, retaining one vegetative branch (smooth shoot) during pruning gives the highest yield.
