摘要

Through a pot experiment,effects of various microbial inoculums on soil microbial diversity and enzyme activity in a typical reclaimed mining area in Shanxi Province were discussed based on quantitative analysis of PLFA,soil urease,phosphatase and sucrase activity. The results showed that the application of microbial inoculums increased microorganism quantity in rhizosphere of rape by 2. 3%-66. 4%,and quantities of bacteria,gram-positive bacteria,gram-negative bacteria,fungi and actinomycetes in the treatments with microbial inoculums were significantly higher than the contrast( P <0. 05),while there was no obvious change in protist quantity. In comparison with the contrast,the application of various microbial inoculums also improved soil urease,sucrase and phosphatase activity by 4. 2%-61. 4%,18. 0%-32. 5% and 64. 2%-199. 0% respectively. It indicated that the application of microbial inoculums can improve soil microbial diversity and enzyme activity,so it is an effective way to speed up ecological restoration of soil.
