1977 after the "cultural revolution", colleges and universities across the country resumed enrollment, and the Department of Soil Chemistry enrolled 1~2 classes every year. Under the guidance of the spirit of the Third Plenary Session of the 11th CPC Central Committee, teaching and scientific research have entered a period of all-round development. According to the needs of social development and economic construction, the teaching plan and training objectives have been revised again, and teaching activities have moved towards the road of normal development. According to the needs of land work in China, the Department of Soil Chemistry took the lead in setting up the specialty of land resources (specialist) and master's degree program (soil) in China on 1985. By 1993, the major of land resources was upgraded to the major of land management (undergraduate), and 2~3 classes were enrolled each year. In 2000, a master's degree in land resource management was established, 193. After the establishment of land resources specialty, teaching and scientific research are closely combined with land management (land resources survey, overall land use planning, land evaluation, basic farmland protection, etc.). ), which has increased the vitality of teaching and scientific research, adapted to the urgent needs of the country, and trained the first batch of land science and technology professionals for our province. Now some people have served as department heads and professors, making contributions to national and provincial land management. 1989 according to the adjustment of school disciplines, the major of agricultural environmental protection was merged from the department of plant protection into the department of soil chemistry. 1993 according to the needs of social development, the undergraduate direction of agricultural environmental protection was established in the specialty of soil and plant nutrition.
