Seek the detailed development history of agriculture in China.

About seven or eight thousand years ago, the main farming method of primitive agriculture in China was slash and burn. People first cut down trees with stone knives and axes, dried them, put them on the fire, and finally turned over the soil with stone plows to sow. But a year or two later, due to the decline of land fertility, people had to migrate to find fertile land.

Bronze farm tools appeared in Shang and Zhou dynasties, but due to the preciousness of bronze, stone plows and hoes are still important tools for people to carry out agricultural production. At that time, people already knew how to ditch and drain water, weed and cultivate soil, use weeds as fertilizer, prevent and control pests and diseases, and greatly improve the land utilization rate. At that time, the land was owned by the state, that is, "the land under heaven is not a king's land."

During the Western Zhou Dynasty, most of the main crops of later generations were already available. Since then, China's agriculture has developed independently and formed its own system, laying the foundation for China's ancient agricultural society.

During the Spring and Autumn Period and the Warring States Period, Chinese traditional agriculture was characterized by intensive cultivation. The farming method is Niu Geng's iron plow. The farming method adopted was the most advanced ridge farming method in the world at that time. Moreover, with the improvement of social productivity and the establishment of private ownership of feudal land, the basic mode of Chinese traditional agricultural social production-self-sufficient small-scale peasant economy with men plowing and women weaving as the unit-has gradually taken shape. Dujiangyan and other agricultural irrigation.

During the Western Han Dynasty, Zhao popularized the combined plough, ordered the sowing tools to be used as lathes, and carried out the field substitution method. The farming system is one crop a year. Agricultural irrigation such as Caoqu, Baiqu and Longshou Canal.

During the Sui and Tang Dynasties, Qu Yuan Plough appeared in Jiangdong. So far, China's plough has been quite perfect and has been used by later generations. Created a convertible.

After the Song Dynasty, with the economic center of gravity moving southward, a stable rice-wheat rotation system was gradually formed in the south of the Yangtze River, with two crops a year and three crops a year in some places. There is a car spinning at high speed.

Wind turbines appeared in the Ming and Qing Dynasties.

1949 10 People's Republic of China (PRC) was founded, China entered a new stage of development, China's rural economy recovered and developed rapidly, and 1952 agricultural production returned to the highest level in history. From 1952 to 1965, China completed agricultural cooperation and people's communalization, and established a unified distribution and purchase system adapted to the planned economic system. Ten years after the "Cultural Revolution" began. Social unrest, everyone is in danger, and the rural economy and agricultural production order have been seriously damaged. The ultra-left route prevailed and the agricultural Dazhai developed abnormally. From 1966 to 1977, the total agricultural output in China basically did not increase.

1978 After the Third Plenary Session of the Eleventh Central Committee opened the prelude to China's economic reform, the stagnant situation of agricultural production was fundamentally changed. This reform began in the countryside, and the most extensive and profound influence is the implementation of the household contract system. According to statistics, from 65438 to 0978, in Anhui Province, where the household contract system developed earliest, the production teams contracted to households accounted for only 0.4% of the total production teams, but by 65438 to 0982, the production teams contracted to households accounted for 92.3% of the total production teams, and a new pattern of rural economy has been fully established.

So far, agriculture in China is still in the period of reform.
