Abstract Background The Gastrodia elata Bl. is an orchid, and its growth demands the presence of Armillaria species. The strong competitiveness of Armillaria species has always been a concern of major threat to other soil organisms, thus disrupting the equilibrium of soil biodiversity. Introducing other species to where G. elata was cultivated, could possibly alleviate the problems associated with the disequilibrium of soil microenvironment; however, their impacts on the soil microbial communities and the underlying mechanisms remain unclear. To reveal the changes of microbial groups associated with soil chemical properties responding to different cultivation species, the chemical property measurements coupled with the next-generation pyrosequencing analyses were applied with soil samples collected from fallow land, cultivation of G. elata and Phallus impudicus , respectively. Results The cultivation of G. elata induced significant increases ( p < 0.05) in soil pH and NO 3 -N content compared with fallow land, whereas subsequent cultivation of P. impudicus reversed these G. elata- induced increases and was also found to significantly increase ( p < 0.05) the content of soil NH 4 + -N and AP. The alpha diversities of soil microbial communities were significantly increased ( p < 0.01) by cultivation of G. elata and P. impudicus as indicated with Chao1 estimator and Shannon index. The structure and composition of soil microbial communities differed responding to differe...
