Agricultural tools and the motivation of Chinese traditional agriculture

He Lei was the main agricultural tool in the Western Zhou Dynasty. Wood and stone farm tools are still widely used, but bronze tools are gradually dominant. Reddy is an ancient agricultural tool operated by human hands with both hands and feet, which is suitable for cooperative coupling farming. More use of iron farm tools and animal-drawn farming began in the Spring and Autumn Period. From the Warring States Period to the Wei and Jin Dynasties, Niu Geng with iron plough was popularized to the whole country from the Yellow River valley and the Yangtze River valley, and agricultural machinery using water power and wind power also appeared. In the Han Dynasty, iron plows began to be fitted with plow walls. In the Tang Dynasty, the curved plow of the lasso drive shaft replaced the straight plow of two cows. Soft covers and hooks appeared in the Song Dynasty, and various forms of plows were suitable for farming in dry land or paddy fields. Various agricultural tools for sowing, irrigation, harvesting and processing are also complete. There was no great development in Ming and Qing Dynasties.
