The four stages of agricultural development in our country

The first stage - primitive agriculture

Primitive agriculture is a kind of agriculture close to the natural state gradually transitioning from gathering and hunting, which is the initial stage of the development of world agriculture and has experienced the development from gathering economy to planting economy. The main use of stone knives, stone shovel, stone hoe and sticks and other production tools, simple and backward. The farming method of primitive agriculture is primitive and extensive, using slash-and-burn. Mainly through engaging in simple cooperative collective labor, to obtain limited means of living, so as to maintain a low level of common living needs, its production development speed is slow, the level of productivity is very low.

The second stage -- ancient agriculture

Ancient agriculture refers to the period from the appearance of iron farm tools to the appearance of agricultural machinery. The main use of hand-made iron tools, wooden tools, such as plows, hoes, harrows, 耧车, windmills, waterwheels and so on. The main labor force of ancient agriculture is human and animal, relying on traditional experience for production, intensive farming, long-term in the state of self-sufficiency of natural economy, agricultural production efficiency is low, production development speed is slow.

The third stage -- modern agriculture

Modern agriculture refers to the agriculture of economically developed countries from the late 19th century to the 1940s. In modern agriculture, semi-mechanized and mechanized agricultural machinery and tools were gradually popularized. Modern agriculture applied the achievements of natural sciences such as botany, zoology, genetics, chemistry and physics to agricultural production, and the production technology system began to take shape. Agriculture has changed from a natural economy to a commodity economy.

The fourth stage is modern agriculture

Modern agriculture originated in the capitalist industrialization period and came into being after the Second World War. It is an era of intelligent agriculture driven by resource integration and data. Its production tools are characterized by intelligence and mechanization. Production based on traditional experience is transformed into production based on scientific knowledge. From a natural economy to a highly developed commodity economy. With the transfer of land, the scale of agricultural land is deepened, and resources are concentrated in the hands of a small number of professional farmers, and technologies such as the Internet of Things, big data and artificial intelligence are used to complete unmanned management. Among them, the application of modern information technology is not only reflected in the agricultural production link, but also penetrates into all links of the agricultural industry chain such as agricultural operation, management and service. It is the intelligence of the entire agricultural industry chain, and the whole process of agricultural production and business activities will be controlled by information flow, forming a new agricultural form of high integration, industrialization and low-cost.
