Value Time of Chinese Cabbage Seeds

Chinese cabbage is planted in July and August every year. 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.

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.

Chinese cabbage is suitable for planting in loam, sandy loam and black loess with rich organic matter, but not in sandy soil which is easy to leak water and feces, and even less in clay with poor drainage.
