In the southern area of Song Dynasty, wagons and new overturned waterwheel keels appeared, and iron plows and pommel horses for transplanting rice instead of Niu Geng appeared. Other farm tools are constantly improving and developing, and the output of farmland crops has also been greatly improved in the Song Dynasty.

During the period of Northern Song Zhenzong, the government ensured the uninterrupted supply of national grain and adapted to the local hydrological conditions. In particular, drought-tolerant and early-maturing rice was introduced from Zhancheng and distributed to people in Jianghuai area for farming. Not only that, rice seeds in the north and south also spread across regions, and millet, wheat and beans in the north began to migrate to the south.
