The problem of soil degradation is becoming more and more serious, how to effectively repair desertified degraded soil has aroused widespread concern. As one of the emerging strategies, plant restoration has great advantages such as high efficiency and low cost, but this technology also has some defects, that is, it is difficult for plants to be established in the coercive environment of ecological destruction. Modified plant growth-promoting bacteria (PGPB) is usually used to increase crop yield. In addition to their proven uses in agriculture, they also have potential in solving environmental problems. This paper analyzes the limitations of solving the problem of environmental degradation based on phytoremediation, and enumerates and explains two methods for screening PGPB. By enumerating the application status of PGPB in promoting the growth of native plants to prevent soil erosion in degraded areas, the importance of plant growth-promoting bacteria to soil quality and microbial structure before plant remediation was discussed. The purpose of this paper is to provide thoughts and suggestions for the study of phytoremediation by combined plant growth-promoting bacteria and plants in desertified degraded soil environment.
