The long-term growth of cotton in Dunhuang City, coupled with the influence of factors such as low temperature and high humidity after sowing, caused the disease of cotton seedlings to increase year by year, especially the occurrence of anthracnose, blight, damping-off, red rot and other seedling diseases. In the same cotton field, serious mixing occurred, resulting in the death of cotton seedlings and the formation of seedlings and ridges, which caused difficulties in cotton production. To control the disease at the seedling stage of cotton, we must conscientiously implement prevention and control. 1. Reasonable rotation of pathogenic bacteria of cotton seedling disease overwintering in the soil in the body, accumulated a large number of pathogenic bacteria in the soil. Therefore, it is necessary to carry out crop rotation, which can greatly reduce and eliminate pathogens in the soil, and have a good effect on controlling blight and anthracnose. 2. The fine preparation site encourages deep-turning after the autumn harvest each year. Through freeze drying, some pathogens can be frozen to reduce the risk of pathogenic bacteria on the surface of the soil. The bottom fertilizer should be applied before sowing, and the ground should be leveled and thinned to facilitate emergence. 3. Select fine seeds to use fully mature, healthy, full, strong seed germination, ensure germination, make cotton seedlings robust. 4. Before sowing, drying seeds before sowing can break the dormancy of cotton seeds, increase their viability, and use ultraviolet rays in the sun to kill pathogens on the surface of seeds. About 20 days before sowing, choose a sunny day to expose the cotton seeds for 3 to 5 days. The drying seeds should not be carried out on the slate or cement field to avoid burned cotton seeds and affect germination. Should not be too thick, usually 10 to 13 centimeters, can be turned 3 to 5 times a day, to ensure that the sun evenly. 5. Chemical seed dressing is a simple and effective measure to control the disease at seedling stage. 1 Seed dressing: Use 50% carbendazim 500g watered 2 ~ 3 kg or 55% enemy pine 500g watered, mixed cotton 100 kg. 2 cotton seed coating: before planting, use Jinhua seed coating agent 1 kg watered 0.5 kg can be coated seed 50 ~ 60 kg or use Weifu suspension seed coating agent 200 ml evenly stirred coating seeds 50 kg. 6. Suitable sowing early sowing, temperature and soil temperature is low, slow emergence is conducive to the invasion of bacteria, late sowing is not conducive to the normal growth of cotton seedlings. Under normal circumstances, when the average temperature is stable at 10 °C, 5 cm below the membrane temperature of 12 °C, you can film seeding, sowing depth of 2 to 3 cm is appropriate. 7. Strengthen the management of seedlings and timely cultivating loose soil after emergence and after rain, remove the consolidation to increase the ground temperature, in order to facilitate the development of the root system and reduce the incidence; the principle of weakening, removing the residual, and removing the disease when thinning the seedlings, and bring out the diseased seedlings Fields are destroyed and destroyed to prevent the spread of germs. 8. Chemical control of cotton seedlings, in case of low temperature and rain or cold invasion, seedling disease is likely to occur in the epidemic, and timely spraying protection. Select 50% carbendazim 800 to 1000 times or 50% of the special 800 ~ 1000 times liquid spray, spray once every 7 to 10 days, even spray 2 to 3 times.
