The application of Niu Geng technology in China began in the Spring and Autumn Period and the Warring States Period. It is a sign that human society has entered a certain civilized era.
Niu Geng began in the Spring and Autumn Period and the Warring States Period in the East. After Shang Yang's political reform, Qin came from behind and was widely used. At that time, horses were also used to cultivate land. In order to attach importance to agriculture, Shang Yang stipulated: "Those who steal horses die, and those who steal cattle add." It is said in Salt and Iron Theory that "the ancients" used horse-drawn carts when walking and "stopped farming". The "ancients" mentioned by the Han people refer to the Warring States and the Qin Dynasty. Modern archaeology has found that many kinds of ironware, such as iron plows, have appeared in ancient tombs in the late Spring and Autumn Period.
Extended data:
The popularization of Tieli Niu Geng shows that the productive forces have developed, which has promoted the development and progress of society and the development of small-scale peasant economy. The appearance of Niu Geng marks the progress of human productivity and the agricultural society has reached a new height. The combination of animal power and iron provides conditions for intensive cultivation.
"Farming, you don't have to learn, people do what they do." It shows that the technical content of farm work is low and simple. As the technology of Niu Geng, its "technical content" is relatively high and it is difficult.
Nowadays, as a symbol of the farming era, Niu Geng technology has already withdrawn from the historical stage. Cattle raising has been replaced by many agricultural machinery and is no longer the main "power" of agricultural production.
