Treatment of several special conditions after cotton sowing 1. Insufficient lyricism After cotton is sown, it is necessary to check the soil moisture in time. For the poorly plucked and possibly dry cotton fields, it is possible to dig small water at the edge of the seed sulcus; water-free irrigated cotton fields can be crushed before seedling emergence. Hey. 2. After raining, it rains after sowing cotton, and the ground is easy to form a shell. After the rain, it should be timely scratched and loosen to remove the compaction to help the seedlings unearthed. If the soil is too thick, the soil shall be used to save the seedlings; the seedlings that emerge will not withstand the sun's strong light, and when the seedlings are planted, a small amount of wet soil shall be kept in the upper part of the seedlings. 3, incomplete emergence of cotton after sowing, it is necessary to promptly check the emergence of seedlings, if it is found missed sowing or rotten species, bad buds, early reseeding germination; found missing lines, immediately transplanted seedlings and plants. Before emergence of a true leaf, the cotton seedlings were transplanted with buds and seedlings were transplanted with tape. Regardless of the transplanting method used, watering should be minimized to reduce the time for seedlings. In order to prevent seedlings from sprouting seedlings, transplanted cotton seedlings should occupy more space. 4, encountered cold weather during the emergence of cotton sowing, often the weather is changeable, once encountered low-temperature weather, it is necessary to timely increase the temperature, or sway turfgrass ash to increase soil temperature around the cotton seedlings. When necessary, cotton seedlings can be sprayed with 36% carbendazim cotton and 1000-1500 times liquid or 50% sterilization star 1000 times to prevent blight and anthracnose from spreading.
