What changes have taken place in farming techniques in Jiangnan during the Ming and Qing Dynasties? What are the reasons for the slow development of ancient farming techniques in China from the Spring and Autumn Period and the Warring States Period to the Ming and Qing Dynasties? Changes: Niu Geng withdrew in large numbers, and Jiangdong Plough, which represented advanced productive forces in the Tang and Song Dynasties, was replaced by Tieta in the Ming and Qing Dynasties. The fundamental reason is that the population has increased, the cost of raising cattle is high, iron is used by people, and Jiangdong plough is used by cattle.

The slow development of ancient farming techniques in China is rooted in the self-sufficient small-scale peasant economy.
