In order to cultivate Chinese cabbage, we must first select the plots. Because the root system of Chinese cabbage is shallow and requires high soil moisture and nutrients, we should choose the soil with strong water retention and strong fertility. Chinese cabbage seeds are small and require a flat topography and fine crushing of soil particles in order to ensure high seedling emergence and uniformity of emergence. In order to enhance the soil's ability to retain water and fertility, the soil will be soft, the roots will develop well, and the range of water and nutrients will be increased to require deep plowing. In order to reduce the damage caused by insects in latent soil, after the land is ploughed, it should be implemented as earthworms or short-term earthworms.
Deep plowing of soil and leveling of land are general requirements for site preparation, but they must also be implemented according to different circumstances. If there is less rainfall, deep plowing should be done; if the previous crop is harvested, whether it is deep plowing or shallow plowing, shallow plowing should be done before sowing, so that the soil is loose and the ground is flat. The depth of deep plowing is generally 30 to 35 cm, the depth of shallow plowing is 15 cm, and the depth of cultivated land is 3 to 5 cm.
