In the Yuan Dynasty, in addition to Wang Zhen's agricultural books, there were two famous agricultural books, Nong Sang Summary and Nong Sang Summary. In this historical period, it is not accidental that several agricultural scientific works can be produced one after another. First of all, our hardworking ancestors have accumulated rich agricultural production experience in long-term production practice from generation to generation. As early as the Warring States Period in the 5th century BC, China's agricultural production techniques began to be intensively cultivated. From the Warring States Period to the early years of the Yuan Dynasty, 1700 years passed. In this long period, the technology of agricultural production has been continuously improved, the production experience has been richer, and agricultural production has also made greater development.
In the process of unifying China in Yuan Dynasty, feudal rulers gradually saw that agricultural production was beneficial to feudal exploitation. When Yuan Shizu suddenly came to power, he began to take some measures to develop agricultural production, set up agricultural persuasion officers, and set up organizations specializing in agriculture, mulberry and water conservancy, which promoted the compilation of agricultural books. But the compilation of these agricultural books is mainly because farmers have mastered the production technology. Secondly, the authors of these agricultural books summed up the experience of farmers' hard work.
