This region is dry and has long, cold winters. Drought-tolerant crops such as millet and gaoliang are common. Wheat, corn, and cotton are also planted extensively, especially where irrigation water is available. The North China Plain lies south of the Great Wall and extends from the coast to the mountains and hills to the west and south. He are the main features.
Several problems exist here.
There is not enough rainfall, the winters are cold and long, and some of the soils are salty because of poor drainage. The main crops are wheat, barley, cotton, corn, gaoliang, millet, and peanuts. The fields in this region are large, and heavy farm machinery has been used extensively. The chief crops include spring wheat, corn, millet, gaoliang, flax, and soybeans. A great deal of land reclamation has taken place in Heilongjiang Province.
