Impact of planting Phallus rubrovolvatus on physicochemical and microbial properties and functional groups of soil

Abstract

Abstract Purpose Soil microbial communities are critically important to agricultural ecosystems. The present study aimed to evaluate the changes in soil microbial community composition and functional groups after planting Phallus rubrovolvatus. Methods Illumina platform were adopted to characterize the bacterial and fungal diversity in the soil cropped with P. rubrovolvatus for 0 and 1 year. Results The results showed that planting P. rubrovolvatus reduced the bacterial and fungal diversity in the soil, and the dynamics of the soil bacterial diversity changed more drastically. This study also indicated that, as keystone taxa, the dominant bacteria (Actinobacteria, Sphingomonas, Xanthobacteraceae, and Gemmatimonadaceae) and dominant fungi (Mortierellales and Eurotiales) served as a key component in the network of soil microbial communities. Moreover, the bacterial and fungal communities in the soil planted with P. rubrovolvatus formed more similar and weak networks. Conclusion Planting P. rubrovolvatus significantly influenced the structure and composition of microbial communities. In the future, we will focus on ways to improve the soil environment after planting P. rubrovolvatus.
