Old seedlings should not be easily plowed. The sooner the drainage, the more active the disaster relief. (2) Heavy rain injury seedlings, big fertilizers nourish. The loss of fertilizer in the cotton fields in the backwaters was much more likely. One had to catch the quick-acting fertilizer once it rained, and the other needed to increase the number and amount of fertilizers, and applied urea 15-20 kg to 667 square meters. After a lot of peaches, the amount of topdressing should be increased. (3) loose soil training, ventilation and loose wet. After the rain, the cotton field is severely knotted. After grabbing topdressing, it is necessary to cultivate the soil as soon as possible. One can increase the permeability, the second can promote new roots, and the third can prevent the cotton plants from lodging. 2, cotton drought. Drought inhibits fertility in cotton, causing premature aging and reducing yields. Corresponding technologies are: (1) Fertilization with water, trickle irrigation. (2) Spray fertilizer to adjust temperature and reduce shedding. Every 667 square meters of cotton special fertilizer 100 grams plus urea 400 grams, spray 30-40 kg of clean water.
