Origin and habitat
Cabbage was originally distributed in north China and is widely cultivated throughout China[4] .
Cabbage is hardy and prefers cooler climates, so it is suitable for growing in cooler seasons. If it is cultivated in the hot season, it is prone to diseases and insects, or poor quality and low yield, so it is not suitable for cultivation in summer. Its resistance to low temperature is very strong. After the temperature reaches -3℃, if it can gradually warm up, it can also resume growth, but if it reaches -8℃ after the temperature continues to fall to -11℃ or so, it can't resume normal growth and suffers from frost damage. Cabbage is suitable for planting in fertilizer, water and rich in organic matter loam and sandy loam and black and yellow soil, not suitable for planting in sandy soil that is easy to leak water and manure, and even less suitable for planting in poorly drained clay soil.
