Background   Dendrobium  is a precious herbal that belongs to Orchidaceae and is widely used as health care traditional Chinese medicine in Asia. Although orchids are mycorrhizal plants, most research still focuses on endophytes, and there is still large amount unknown about rhizosphere microorganisms. To investigate the rhizosphere microbial community of different  Dendrobium  species during the maturity stage, we used high-throughput sequencing to analyze microbial community in rhizosphere soil during the maturity stage of three kinds of  Dendrobium  species.    Results  In our study, a total of 240,320 sequences and 11,179 OTUs were obtained from these three  Dendrobium  species. According to the analysis of OTU annotation results, different  Dendrobium  rhizosphere soil bacteria include 2 kingdoms, 63 phyla, 72 classes, 159 orders, 309 families, 850 genera and 663 species. Among all sequences, the dominant bacterial phyla (relative abundance > 1%) were Proteobacteria, Actinobacteria, Bacteroidetes, Acidobacteria, Firmicutes, Verrucomicrobia, Planctomycetes, Chloroflexi, and Gemmatimonadetes. And through WGCNA analysis, we found the hub flora was also belong to Acidobacteria, Actinobacteria and Proteobacteria.    Conclusions  We found that the rhizosphere bacterial communities of the three kinds of  Dendrobium  have significant differences, and that the main species of rhizosphere microorganisms of  Dendrobium  are concentrated in the Proteobacteria, Actinobacteria, and Bacteroidetes. Moreover, the smaller the bacterial level, the greater the difference among  Dendrobium  species. These results fill knowledge gaps in the rhizosphere microbial community of  Dendrobium  and provide a theoretical basis for the subsequent mining of microbial functions and the study of biological fertilizers.
