Abstract：Based on the main types and distribution of degraded soil in China, different amelioration techniques of degraded soil were compared and analyzed. Combined with the research situation at home and abroad and the raw materials and classification of soil amendments, the main functional effects of soil amendments on soil and crops were summarized. The research results of soil amendments in acidified soil, saline-alkali soil and heavy metal contaminated soil were expounded, and the problems existed in the application of soil amendments in different types of degraded soil were put forward. Finally, the main problems in soil conditioner research and development and application process were further explored. Combined with the green and sustainable development orientation, pointed out that strengthening the application basic research, the research and development of new and environmental protection and low-cost, the application evaluation, the application standard establishment, the certification ma-nagement of soil amendments and the comprehensive management of degraded soil is the develop-ment tendency of soil amendments research and application.
