two. Cultivation should be late or not. In the production process of autumn cabbage, three major diseases of downy mildew, soft rot, and viral disease are often encountered. Such as the early cultivation of Chinese cabbage due to the Department of summer high temperature and humidity often cause poor seedling growth, to create conditions for the spread of the disease, this should be appropriate late sowing, vigorous seedlings can effectively avoid the occurrence of disease, the most appropriate The sowing date is 3-4 days before the beginning of autumn. three.
