Microbial Diversity in Rhizosphere Soil of Rhododendron moulmainense with Different Tree Potential in Wutong Mountain of Shenzhen

[Objective] This study aimed to explore the relationship between the degradation of tree potential of Rhododendron moulmainense and the physical and chemical properties as well as the microbial community structure in the rhizosphere soil in Wutong Mountain of Shenzhen by analyzing the physical and chemical properties and microbial community diversity of the rhizosphere soil.[Method] The water content,pH value,organic carbon,total nitrogen,and mineral nitrogen of rhizosphere soil of R.moulmainense trees with different tree potential in Wutong Mountain were analyzed.Additionally,the DNA of rhizosphere soil was extracted,and was used to investigate microbial diversity and community structure using high-throughput sequencing technology.[Result] The result showed that there was no significant difference in physicochemical properties of rhizosphere soil among the three tree potentials.A total of 681 807 effective bacterial sequences were detected in rhizosphere soil of three tree rhizosphere,with an average of 79 8
