What are the four granaries in China?

1, Northeast Plain:

The northeast plain is fertile and is one of the only three black soil areas in the world. The grain output of the four northeastern provinces accounts for one third of the country's total output. It is an important production base of grain, soybean and animal husbandry in China, and also an important base of coal, steel, machinery, energy and chemical industry in China. ?

2. North China Plain:

The soil layer in North China Plain is deep and fertile. The main food crops are wheat, rice, corn, sorghum, millet and sweet potato, and the cash crops are mainly cotton, peanuts, rape, sesame, soybean and tobacco. North China Plain is an important grain, cotton and oil production base in China.

3, the middle and lower reaches of the Yangtze River plain:

The plain in the middle and lower reaches of the Yangtze River is an important production base of grain, oil and cotton in China, and it is also the region with the richest water resources in China. The natural water system of the Yangtze River and criss-crossing artificial canals make this area the densest river network area in China. At the same time, this area is the most concentrated area of freshwater lakes in China. The famous freshwater lakes are Poyang Lake and Dongting Lake.

4. Pearl River Delta Plain:

The estuary along the southeast coast of China forms a delta plain, of which the Pearl River Delta is the largest. It is formed by the confluence of three major rivers, namely, the east, the west and the north, with an area of over 6,543,800 square kilometers, and is one of the commodity grain bases in China. The area is small, but the productivity is very strong, and it can feed nearly a thousand people per square kilometer.
