Cabbage rot disease is a common disease. There are many causes of the disease. There are roots caused by physiological diseases and pathological roots such as soft rot. This has a lot to do with rain, soil moisture, and temperature fluctuations. 1. Cabbage belongs to cool and cool vegetables. The suitable temperature for growth is 10-22°C. When the temperature is over 32°C, the photosynthesis is weak and the respiration is enhanced. The growth is very weak. Cabbage is a hi wet vegetable, and it requires moist soil conditions throughout the growing season, especially the Chinese cabbage can not lack water in the rosette period and the package period. Chinese cabbage is also not resistant to waterlogging, and long-term waterlogging can also cause roots to die. Because in the hot season, in the event of continuous rain, the soil is full of moisture, lack of oxygen, anaerobic respiration of cabbage roots, will lead to root cell death. 2. When the seedlings are onset, the base of the stems is immersed in water, rotted, lodging, and falling star-shaped. In the case of adult disease, most of the outer leaves become wilted during the day, recover at night, and then gradually die from the outer leaves. The roots turn brown and rot. The roots shrink in the middle and the lower part disappears, leaving only the upper part. 3, prevention and control methods: 1 choose to plant high or flat terrain. 2 Avoid continuous cropping of cruciferous vegetables. 3 disease is best changed live broadcast transplanting. 4 to prevent flooding after flooding and irrigation and after the rain. 5 In the early stage of disease, it can be controlled with pesticides in time, and can be used to irrigate or spray the plant stem base and surrounding soil with 72% Kelu 1000 times liquid, or 72.2% Prec 800 times liquid, or 15% hymexazol 400 times liquid.
