Agriculture in China took place in the Neolithic Age. The Yellow River and Yangtze River basins in China are one of the cradles of world agriculture. In the development of 89,000 years, China's agriculture once had many inventions that were ahead of the world, but it also experienced a long period of stagnation.
The production structure of agriculture in China includes planting, forestry, animal husbandry, fishery and sideline; But for thousands of years, it has been mainly planted. Due to the large population and relatively small cultivated land area, grain production is particularly dominant.

Basic features:
(1) Integrity.
They are interrelated and restricted to form a unified whole. For example, under certain hydrothermal conditions, a certain amount of soil and vegetation, and corresponding animal and microbial communities are formed.
② regionality.
Due to the relative position of the earth and the sun and their movement characteristics, as well as the distribution of land and sea on the earth's surface and the changes of geological landforms, the hydrothermal conditions in different regions of the earth are different.
③ Reproducibility.
Different from the situation that mineral resources tend to decrease with the development and utilization, agricultural natural resources are renewable and recyclable. Mainly manifested in the periodic recovery of soil fertility, the constant death and reproduction of organisms, the circular supply of water, seasonal changes in climatic conditions and so on.
④ Culturability.
Although human beings can't create natural resources, they can take various measures to change their shape and nature to some extent. For example, by improving soil fertility, improving water conservancy and cultivating excellent biological varieties, the production potential of natural resources can be further exerted.
⑤ The finiteness of quantity and the infinity of potential.
The area of land on the earth, the amount of water, and the amount of solar radiation reaching the ground. , are limited to a certain area and a certain period of time.
