What effect did Qu Yuanli's invention have on the development of ancient agriculture?

Qu Yuan's plough was invented by the working people in China in the Tang Dynasty. Its axis curve, because of its name, is different from the straight axis plow. Because it was first popularized and applied in Suzhou and other places, it is also called Jiangdong Plow.

Compared with the previous plough, Qu Yuan's plough has several major improvements. First, the straight shaft and long shaft are changed into curved shaft and short shaft, and the plow plate which can rotate freely is installed at the shaft head, which not only makes the plow frame smaller and lighter, but also facilitates turning around and turning, which is flexible in operation and saves manpower and livestock.

Its appearance marks the maturity of ancient farming tools in China. Before the plow was widely used, it was the main farming tool. Animal-drawn plows have been gradually popularized in some places since the Spring and Autumn Period and the Warring States Period.

Qu Yuan's strength in the Tang Dynasty embodies the creativity of the Chinese nation. It not only has exquisite design and exquisite craftsmanship, but also contains some aesthetic laws, which has far-reaching historical and social significance. In the design of contemporary farm tools, Qu Yuan's plough still has a good reference significance.
