Origin of Chinese cabbage:

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.

If the temperature reaches -8℃ and continues to drop to about-1 1℃, it will not be able to resume normal growth and suffer from freezing injury. Chinese cabbage is suitable for planting in fertile land. Loam, sandy loam, black loess and other soil with water retention and rich organic matter are not suitable for planting on sandy soil that is easy to leak water and feces, nor on clay with poor drainage.
