Abstract

A field experiment was conducted to analyze the changes of soil nutrients in mining area after different microbial plant combined remediation. The results showed that the application of microbial agents could significantly increase soil total nitrogen content in coal mine area. The contents of GH, GS and GX were the highest, which were 0.54, 0.51 and 0.41 g/kg, respectively. The contents of available phosphorus and available potassium in AX treatment were the highest, reaching 57.1 and 194 mg/kg. Comprehensive analysis showed that microbial agent + mixed seed mode could effectively increase soil catalase content, among which AH had the best effect.
