Effect of combined microbial-plant remediation on soil physical properties in mining area

 In view of the problems of vegetation damage, soil water and fertilizer shortage, soil heavy metal pollution, ecosystem damage and other problems existing in the long-term mining of the coal mine area, this study uses micro-organism-plant to bioremediation the coal mine area. The changes of soil physical properties were studied through pot experiment. The results show that the combined remediation can change the physical properties of soil to a certain extent, but the effect is not significant in the short term.
