The following is the introduction of Chinese cabbage:

Chinese cabbage is a biennial herb with a height of 40-60 cm. The whole plant is slightly white and hairless, and sometimes there are several bristles on the lower midvein. Basal leaves are large, obovate oblong to obovate, 30-60 cm long, blunt at the top, wrinkled and wavy at the edge, sometimes with inconspicuous teeth, and the midvein is white and wide.

Chinese cabbage was originally distributed in North China and widely cultivated in China. Cabbage is hardy, likes cold climate and is suitable for growing in cold season. If cultivated in high temperature season, it is prone to pests and diseases, or the quality is poor and the yield is low, which is not suitable for summer cultivation.

Its low temperature resistance is very strong. After the temperature reaches -3℃, if the temperature can be gradually increased, the growth can also be resumed, but after reaching -8℃, if the temperature continues to drop to about-1 1℃, the normal growth cannot be resumed and it will suffer from freezing injury.
