Ancient agricultural poems

During the Qin and Han Dynasties, the southern part of China was still a region with a vast territory and a sparse population and backward production, and extensive farming techniques such as fire tillage and hydroponics were mostly used. During the Eastern Han Dynasty, rice production in China began to develop from direct seeding to transplanting. After the "An Shi Rebellion" in the Tang Dynasty, a large number of people in the north moved south, and advanced tools from the north were introduced to the south, which promoted the development of farming technology in the south. Lu Guimeng recorded in Lei Ji Jing that the farming methods in the south of the Yangtze River in the late Tang Dynasty were "ploughing and ploughing" ... harrowing and driving. Because the role of grinding wheel in breaking clods, mixing mud and leveling fields is not ideal, it was improved in the Song Dynasty and a wheel was made. Wang Zhen's "Agricultural Book" said that this kind of farm tool "sees the work quickly, and then uses it after plowing and harrowing, and the soil begins to ripen." It plays a very good role in breaking soil blocks, mixing mud and leveling fields. Working with this farm tool has become an important part of paddy field farming in the Southern Song Dynasty. This point has been recorded in Lou Yi's "Poetry of Farming and Weaving" in the Southern Song Dynasty: "When I leave the field, I will see the end of the field and travel all over the border to help me." From then on, a farming technology system combining tillage, harrowing and tillage was formed in southern paddy fields.
