ZG's agricultural heritage research can be roughly divided into four stages: (1) 19 to 1954. The germination of agricultural heritage research. Several predecessors have done some pioneering practical work in agricultural heritage research. In addition to the early explorations of Luo Zhenyu and Gao Runsheng in the late Qing Dynasty, Luan Tifu and Hu in cheeloo university during the Republic of China also engaged in the study of Qi Yao Min Shu in their early years. Jinling university. Other influential works include History of Water Conservancy by Zheng (Commercial Press, 1939), History of Disaster Relief by Deng Yunte (Commercial Press, 1937) and History of Fisheries (Commercial Press, 1937). 192 1 year, Jinling university library set up a special agricultural history information department and began to systematically collect ZG ancient agricultural materials, and the research on ZG agricultural heritage began to sprout. (B) 1954 to 1966, Preliminary Development of Agricultural Heritage Research In the early 1950s, New China was just established. Facing the blockade of western countries, the people of China strive for self-improvement and attach importance to the use of existing resources. ZG is rich in cultural heritage (agronomy, medicine, literature, etc.). ), agronomy and medicine are most closely related to the national economy and people's livelihood. Therefore, in the upsurge of studying and sorting out the outstanding cultural heritage of the motherland, a number of specialized agricultural heritage research institutions have been established one after another. 1954 In July, with the support of the Central Rural Work Department, the Agricultural Office of the State Council and the Ministry of Agriculture, the Agricultural Heritage Research Office, the first specialized research institution in China with ZG agricultural history as its main task, was established in Nanjing, under the dual leadership of China Academy of Agricultural Sciences and Nanjing Agricultural College, with Mr. Wan as the first office director. 1956 northwest agricultural college established paleoagricultural laboratory. Subsequently, Beijing Agricultural College and South China Agricultural College also established agricultural history research institutions. Gradually formed four ZG agricultural heritage research bases represented by "Dongwan (Wan Guo Ding), (Shishenghan), Nanliang (Liang Jiamian) and (Wang Yuhu). In terms of scientific research, the focus of this period is to sort out and annotate ancient agricultural classics, and various agricultural heritage research units have done a lot of related work and achieved outstanding results. They have published Agricultural History of China (I), Agricultural Records of China, Compilation and Interpretation of Fan Sheng Zhi's Books, Revision and Interpretation of Qi Yaomin's Books, Compilation and Interpretation of Four People's Monthly Orders and Compilation and Interpretation of Four Seasons. (3) 1966 to P977, the research on agricultural heritage stopped. Due to the Cultural Revolution, most of the research work in this period stopped, and the ZG Agricultural Heritage Research Office was merged into Jiangsu Academy of Agricultural Sciences and renamed as the Agricultural Technology History Research Office. Most other agricultural history research institutions in China also suffered the same fate. (D) 1978 till now. Great development of agricultural heritage research. After the reform and opening up, scientific research gradually returned to normal. 1984 after years of preparation, ZG agricultural history society was established at Zhengzhou conference, which announced the arrival of ZG agricultural heritage research spring. During this period, not only the agricultural heritage research institutions established before the Cultural Revolution were restored, but also some new scientific research units-www.bfblw.com/lw.asp? were established. ,。 ID= 16 1 paper net, such as the Agricultural History Research Office of Zhejiang Agricultural College, Agricultural History Research Office of Hebei Agricultural College, Jiangxi Agricultural Archaeological Research Center, ZG Agricultural Museum, Contemporary Agricultural History Research Office of Rural Economic Research Center of Ministry of Agriculture, etc. Some places, such as Guangdong, Henan, Shaanxi, Jiangsu and other provinces, have also established provincial agricultural history research societies. Some specialized agricultural history research publications have also appeared one after another, such as China Agricultural History, Agricultural Archaeology, Agricultural History Research, and Ancient and Modern Agriculture. Agricultural heritage education has also ushered in spring. 198 1, ZG Agricultural Heritage Research Office was authorized by the State Council to grant a master's degree in agricultural history, 1986 to grant a doctor's degree, and 1995 to grant a postdoctoral mobile station in the history of science and technology (agricultural history). In addition, Northwest A&F University has a doctor's degree in agricultural history in the discipline of agricultural economic management; South China Agricultural University has a doctorate in crop science and agricultural history. Other universities that have the right to award master's degrees in agricultural history include Beijing Agricultural University and Yunnan Agricultural University, from which ZG agricultural heritage research has established a pyramid-shaped multi-level talent training structure from master's degree to doctor's degree to postdoctoral degree.
