| 【Objective】The rhizosphere soil of Davidia involucrate in different regions was tested in order to
understand the species and diversity of the rhizosphere microorganisms, and provide basic data and theoretical basis for the
introduction and breeding of D. involucrate. 【Method】High-throughput sequencing was applied to study the microbial
species and diversity of rhizosphere soil of D. involucrate in three regions of Zhaotong, and the species composition and
abundance, Alpha diversity, Beta diversity and microbial community structure were analyzed. 【Result】The results
showed that Alphaproteobacteria was the most abundant in the bacterial community (>17.02%), Fungal community was
obviously different in three regions. Pezizomycetes was the most abundant fungi class (17.01%) in Yongshansanjiangkou,
Archaeorhizomycetes was the most abundant fungi class (29.79%) in Yiliangxiaocaoba, Sordariomycetes was the most
abundant fungi class(20.77%) in Zhenxiongtangfang. Among the three regions, the microbial community structures in
Sanjiangkou, Yongshan and Tangfang, Zhenxiong were highly similar. The rhizosphere soil in Sanjiangkou, Yongshan
reflected the richest bacterial diversity, while that in Tangfang, Zhenxiong mirrored the richest fungal diversity. 【Conclusion】
The microbial community in rhizosphere soil of D. involucrate in the three regions had high biodiversity, but there were
differences in the distribution of species composition. |
