Abstract: Oral history of science and technology recently emerges as a new research field in the history of science and technology in China. Under the action of the Academic Growth Data Collection Project of Old Scientists, this paper investigated the practice experience and the academic data of two agricultural scientists, and summarized the preparation, process and interpretation of oral datasets, and proposed an idea of multiple historical data mutual evidence that might become useful in examination and identification of oral data. Furthermore, it briefly introduced the purpose, content and process of the oral agricultural science and technology history, and hopefully that might provide insight to promote the development in the field of agricultural science and technology history.
