At present, cotton is in the seedling stage, which is a crucial period for cultivating strong seedlings and promoting early seedling growth, which is a high yield and high yield of cotton. As one of the three major cotton-growing counties in Shaanxi Province, the reporter saw in the Daxie Cotton Technology Experimental Demonstration Base in Tongdi Village, Yanqiao Township, that cotton farmers have fixed seedlings and sprayed foliar fertilizers in their respective cotton fields. Because the cotton seedling stage is dominated by growth, that is, the period of long roots, stems and leaves, cotton grows weakly and has poor resistance to stress, and cotton seedlings are often accompanied by natural disasters such as low temperature, drought, pests and diseases, such as management. Inadvertently, it is easy to cause the cotton field to lack the seedlings and stems. In this regard, Xia Zhiming, an associate professor at the College of Agriculture, Northwest A&F University, suggested that cotton seedlings should be classified according to the corresponding measures, namely, to prevent low-temperature freezing damage, but also to prevent high-temperature burning, strengthen management, early detection of seedlings, replenishing seedlings, and doing everything possible to preserve seedlings and breeding. Strong seedlings promote early development and lay a solid foundation for capturing cotton production throughout the year. The disease of cotton seedlings is mainly caused by blight and anthracnose. The factors such as low temperature, rainy, heavy sputum and early sowing in seedling stage are important causes of cotton seedling disease. Xia Zhiming said that on the basis of doing a good job in seed disinfection and soil treatment, we should focus on the cultivation management and chemical control measures at the seedling stage. Xia Zhiming suggested: First, after the emergence of cotton, the ability to absorb inorganic nutrients is weak, the leaf area is small, and the organic nutrients produced by photosynthesis are insufficient. Coupled with the adverse weather environment, root growth is more difficult, which increases the disease. happened. Therefore, the cultivation of cotton at the seedling stage and the improvement of the ground temperature are necessary means to solve the disease at the seedling stage, and it is necessary to be early, deep and diligent. Secondly, spray 1-2 times of humic acid foliar fertilizer after emergence to improve the resistance of cotton seedlings to low temperature and disease resistance. In the early stage of the disease, spray 50% carbendazim WP or carbendazim WP 3000 times spray and root irrigation, according to the situation every 5-7 days, 1 time, continuous control 2-3 times, with foliar fertilizer effect better.

Immunity, which has been developed over the course of human evolution, can help protect the body from viruses. It is a mechanism of the body. He can develop a kind of resistance to outside bacteria, viruses and other viruses that invade. Immunity can be divided into innate immunity and acquired immunity. People with low immunity are prone to infection with viruses, leading to allergic reactions and frequent autoimmune diseases. The immunity OF the room is low, the performance is the constitution is weak, malnutrition, spirit is flagging, fatigue is weak, appetite is reduced.
