Abstract Background: Dendrobium is a precious herbal belongs to Orchid and widely used as health care traditional Chinese medicine in Asia. Although orchids are mycorrhizal plants, most researches still focus on endophytes, and there is still large unknown in rhizosphere microorganisms. In order 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 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, Gemmatimonadetes. We analyzed the environmental factors of the growth of Dendrobium and found that the environmental factor that affects the rhizosphere soil microorganisms of Dendrobium is the soil factor. Among them, soil factors most closely related to the influence of Dendrobium rhizosphere soil microorganisms include total nitrogen, available phosphorus, ammonium nitrogen and pH value.Conclusions: We found that the rhizosphere bacterial communities of the three kinds of Dendrobium have significant differences, and the main species of rhizosphere microorganisms of Dendrobium are concentrated in the Proteobacteria, Actinobacteria, Bacteroidetes. Moreover, the smaller the level of bacterial, the greater the difference among Dendrobium species. Soil is the most important environmental factor affecting the bacterial communities in the rhizosphere soil of Dendrobium. These results fill the gap 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.
