The Spearman correlations between rhizosphere microbial communities of Paphiopedilum helenae and ecological factors are shown in Figure 9 , SOM and AN exhibited positive mutual correlation, jointly enhancing Chloroflexi abundance while significantly ( p < 0.05) or highly significantly ( p < 0.001) reducing abundances of Myxococcota , Entotheonellaeota, Firmicutes, and Methylomirabilota ; Soil pH showed significant or highly significant negative correlations with Acidobacteriota and Gemmatimonadota , respectively, while demonstrating a highly significant positive correlation wi
