Chinese cabbage is a Brassica plant in Cruciferae and is known as the "king of vegetables". Originated in the north of China, it has been cultivated all over the north and south, and was introduced to Japan, Europe and America in the19th century. It has broad green leaves and white side dishes. Many leaves are tightly wrapped together to form a cylinder, and most of them will form a dense head. The leaves wrapped inside are light green or even light yellow because they can't see the sun.
Geographical distribution:
The origin of Chinese cabbage is the Mediterranean coast and China. South of the Yangtze River is the main producing area, and the planting area accounts for 40%-60% of the planting area of vegetables in autumn, winter and spring. After the 1970s, the planting area in the north of China also expanded rapidly, with large areas planted everywhere. Its planting area and consumption rank first among all kinds of vegetables in China.
