[Objectives] To analyze the microbial community structure and diversity in the rhizosphere soil of peach trees in the Tangshan area of Hebei Province, identify the dominant microbial groups, and explore their potential ecological functions. [Methods] Amplification sequencing analysis of bacterial and fungal communities in the rhizosphere soil of a peach orchard in Qian’an County, Tangshan City, Hebei Province, was performed using Illumina MiSeq high-throughput sequencing technology. [Results] The indices of Sobs, Chao, ACE, and Shannon for soil bacteria in the rhizosphere soil of peach trees were all higher than those for fungi, indicating a more uniform and diverse bacterial community structure. At the phylum level, the bacteria with relatively high abundance included Pseudomonadota (28.29%), Acidobacteriota (18.10%), Bacillota (12.17%), and Actinomycetota (11.73%). In contrast, the fungi with relatively high abundance were Ascomycota (64.64%), Basidiomycota (14.22%), and Mortierellomycota (14.09%). At the genus level, the bacteria with relatively high abundance comprised Sphingomonas (5.00%), Priestia (3.38%), Nitrospira (2.05%), etc. The fungi with relatively high abundance included Fusarium (13.13%), Mortierella (12.86%), Tausonia (6.97%), Neocosmospora (4.77%), etc. [Conclusions] This study offers a foundational dataset and theoretical reference for the regulation of rhizosphere microecology and the management of soil health in peach orchards in Tangshan. |
