The Chinese cabbage seedling period generally refers to the emergence of about eighty-nine true leaves. This period generally requires the principle of “three-water seedlings and five-water setting treesâ€. That is, the first water is poured on the sowing day, and the seedlings are topped with soil. After the water is poured out, it is poured with water again; in addition, water is poured once after two seedlings and one seedling. Generally, during the time of breaking the heart and after each seedling, topdressing is carried out, mainly with thin decomposed manure.
After the Chinese cabbage has been planted, it will grow 15 to 16 leaves from the group tree to the Chinese cabbage. During the rosette period of Chinese cabbage, it should be applied to the tree when it begins to grow. Usually, organic manure is applied at 667 square meters. 500 ~ 1000kg or topdressing urea 10kg, and appropriate increase in phosphorus and potassium fertilizer or plant ash or superphosphate and potassium sulfate. After the fertilization, the water was poured once and then the soil was kept dry and wet during the rosette period.
