1. Quickly clear the ditch and drain the stains. The four ditches are matched and the ditches are deep to ensure that the open water in the field is quickly drained, the groundwater level is lowered, and the damage of water to the cotton root system is reduced.
2. Quickly support seedlings and cultivate soil. Straighten cotton seedlings in time, cultivate soil and protect roots, wash leaves and clean pollution, and break compaction in cultivation.
3. Quickly re-chase the flower bell fertilizer. The flowering boll period is the period when cotton needs a lot of fertilizer, and the heavy rain has caused a serious loss of water and fertilizer to cotton, so it is necessary to quickly re-chase the boll fertilizer. After the cotton returns to normal growth, 10-25 kg of urea and 7-10 kg of potassium fertilizer are applied per mu. After topping, 10 kg of urea per mu is applied as peach fertilizer. At the same time, foliar sprays of potassium dihydrogen phosphate, urea and boron fertilizer are applied in combination with insect control and disease treatment.
4. Quickly do a good job in chemical regulation. After the cotton plant returned to normal growth, spray 35 kg of arthromine with 2-3 grams of water per mu, and spray 5-7 kg of arthroamine with 4-5 grams of water per mu 5-7 days after topping. Rational control can coordinate the growth of aboveground and underground parts, adjust the internodes and plant height of cotton, shape the ideal plant type and group structure, reduce the shade and shedding in the field, increase the bud into boll form, control the ineffective flower buds, and inhibit the growth of buds.
5. Strengthen pest control. After the affected cotton plants resumed their growth, the branches and leaves were young and tender, and there were many aphids in the early stage, and they were susceptible to cotton bollworms and cotton small bridge-building insects in the later stage. Therefore, it is necessary to treat early and ruthlessly, so that every leaf must be protected, and every bud (boll) must be competed for, and the yield of a single plant should be increased to a limited extent. At the same time, due to the high humidity in the waterlogged cotton fields, it is easy to cause rotten bells, so it is necessary to strengthen the prevention and control. In addition, the cotton that has suffered from waterlogging should be appropriately postponed (generally 5-10 days later than normal cotton), watered in time in case of autumn drought, and manually matured in a timely manner in the later stage.
6. For the cotton fields with serious damage, interplant in time before July 25, and replant corn, sesame, soybeans, mung beans and other crops.
The production management measures after the cotton flood are introduced here, and I hope it will be helpful to everyone.
