Soil rhizosphere fungal community structure of different planting systems in 2021. (A) Principal coordinate analysis (PCoA), Reflecting the differences between different planting systems, there was a significant difference between MC and HC in PCoA1; (B) percentage of fungal community structure at the phylum level. In the phylum-level analysis, the fungal community richness was highest for Ascomycota and Mortierellomycota; (C) functional prediction of fungal communities in different planting patterns by FUNGuild. Twenty representative functional groups were predicted and analyzed in total; (D) ACE, Chao1, and Shannon diversity indices. In the analysis of abundance and diversity, the significance of HC was significantly higher than that of the other three planting systems.
