What river formed the North China Plain? What cash crops are suitable for growing in the North China Plain?

The landforms shaped by the Yellow River, Huai River, Hai River, Luan River and other rivers constitute the main body of the North China Plain. The North China Plain is an important grain, cotton and oil production base in China. The North China Plain is an agricultural area dominated by dryland farming. The main food crops are wheat, rice, corn, sorghum, millet and sweet potatoes, and the main cash crops are cotton, peanuts, sesame, soybeans and tobacco.

What river formed the North China Plain?

The North China Plain is formed by the alluvial deposits of the Songhua River. It is bordered by the Bohai Sea and the Yellow Sea to the east, and spans seven provinces and municipalities, namely Beijing, Tianjin, Hebei, Shandong, Henan, Anhui, and Jiangsu, with an area of ​​300,000 square kilometers. The plain has a flat terrain, numerous rivers and lakes, convenient transportation, and a developed economy. It is the political, economic, and cultural center of China, and its population and cultivated land area account for about 1/5 of China's total.

The North China Plain is a Cenozoic fault depression on the North China Platform. In the late Tertiary and Quaternary periods, a large continuous plain was formed. At the same time, the fault block mountains on the edge of the plain were relatively uplifted, and the outline of the large plain became increasingly clear. In the Cenozoic era, it sank relatively and received thicker sediments, with local sediments reaching up to a thousand meters.

The North China Plain is less than 100 meters above sea level, and the terrain is gently sloping. From the foot of the mountain to the coast, there are landforms such as diluvial inclined plains, diluvial-alluvial fan-shaped plains, alluvial plains, alluvial-lacustrine plains, marine-alluvial plains, and marine plains. The landforms shaped by the Yellow River, Huai River, Hai River, Luan River and other rivers constitute the main body of the North China Plain, namely the Yellow River alluvial fan plain; the middle and lower reaches of the Huai River plain; the middle and lower reaches of the Hai River plain; and the lower reaches of the Luan River alluvial fan plain.

What cash crops are suitable for growing in the North China Plain?

The soil layer of the North China Plain is deep and fertile. The main food crops are wheat, rice, corn, sorghum, millet and sweet potatoes, and the main cash crops are cotton, peanuts, sesame, soybeans and tobacco. The North China Plain is an important grain, cotton and oil production base in China. The North China Plain is an agricultural area dominated by dryland farming. North of the Yellow River, the main cropping system is three crops per year, wheat and corn are the main food crops, and cotton and peanuts are the main cash crops. With the development of irrigation, the area of ​​two crops per year is expanding. Most areas south of the Yellow River can have two crops per year, with two years and three crops and three years and five crops as the main crops. The multiple cropping index ranks first in North China. Food crops are also mainly wheat and corn. Since the 1970s, the rice planting area has been expanded along the Huai River and the lake area. The main cash crops are flue-cured tobacco, sesame, cotton, soybeans, etc. The North China Plain is also rich in apples, pears, persimmons, dates, etc.

What is the soil of the North China Plain?

The soil of the North China Plain is loess.

The North China Plain is also known as the Huang-Huai-Hai Plain. It is a plain formed by rivers. The middle reaches of the Yellow River flow through the Loess Plateau. The soil of the Loess Plateau is loose and easily eroded by water. A large amount of loess is lost and left downstream with the water of the Yellow River. The terrain in the downstream is flat, the water flow rate slows down, and silt is deposited and precipitated to form loess. Loess is primary and distributed in thick layers, covering low watersheds, hillsides, and hills. It is often in unconformable contact with bedrock, has no stratification, often contains paleosol layers and calcareous nodule layers, has developed vertical joints, and often forms steep walls.
