Correlation between soil rhizosphere microbial communities and soil nutrients and Redundancy analysis of soil physicochemical properties(A). The correlation between rhizosphere soil nutrients and the rhizosphere bacterial community shows a very significant relationship between Acidobacteria and organic matter (OM); (B) The correlation between rhizosphere soil nutrients and the rhizosphere fungal community shows a very significant relationship between Mortierellomycota and available phosphorus (AP); (C) Underneath the door, the results of fungal community RDA analysis show that the first and second axes explain 54.68% and 32.61% of the total variation in microbial communities, respectively; (D) The results of the RDA analysis at the phylum level for bacteria show that the first and second coordinate axes account for 55.32% and 37.22% of the total variation in the microbial communities, respectively.
