In the seedling stage, the root system is underdeveloped and the absorption is weak. In autumn, it is often hot and dry. Therefore, it is necessary to supply enough water in time, insist on small water pouring and promote root growth. When the heart breaks, a top dressing is carried out. Each time the seedlings are combined with the cultivating, the thin fertilizer is used to raise the seedlings. The rosette period is a period of rapid growth of Chinese cabbage. In this period, water and fertilizer management must be strengthened to promote plant growth. After the seedlings or the plants are slowed down, the fertilization should be carried out between the rows or between the plants. After the top dressing, the vegetables and the stems will be sprayed once to promote the expansion of the cabbage, and then the soil will be watered according to the dry and wet conditions. The ball-forming period is the period of formation of Chinese cabbage products. It requires a lot of fertilizer and water. The management of water and fertilizer during the ball-forming period focuses on the beginning and the middle of the ball. These two times must use fast-fertilizer and must be applied in advance. When filling the heart, it should be topdressed immediately, and the new high-fat film can be used together with the fertilizer to improve the fertilizer efficiency. After the plant is pumped, it can be applied once again. After topdressing, combined with irrigation, the method of watering should be slow water and slow irrigation. The irrigation was stopped 10 days before the harvest, so that the leaf ball was not resistant to storage due to excessive water content.
