After planting, it is necessary to replenish the water needed for the growth of Chinese cabbage, the heat tolerance of Chinese cabbage is poor, and the temperature at noon in autumn is still very high, so it is necessary to reasonably water to reduce the soil temperature and keep the soil moist. In addition to reasonable irrigation, topdressing should be applied in time, sufficient base fertilizer should be applied before planting, and topdressing in seedling stage, rosette stage and heading stage can effectively improve the yield of Chinese cabbage.

3. Bundling management

It should be noted that the first 3-4 can not be watered, after bundling can be poured with small water to promote the growth of Chinese cabbage.

4. Pest control

The diseases and insect pests promoted by Chinese cabbage are aphids, standing blight, quenching disease, downy mildew and so on, which not only seriously affect the growth of Chinese cabbage, but also reduce the yield and quality of Chinese cabbage. Therefore, it is necessary to control in time, give priority to prevention, combine prevention and control, and timely spray control in the peak period of the occurrence of diseases and insect pests to control the spread of germs and pests.
