Soil Bacterial Community Diversity under Mangifera persiciformis in Guangxi

  • 摘要: 2020年6月,以广西南宁市、崇左市扶绥县、百色市田阳区的原生天桃木Mangifera persiciformis为研究对象,采用PacBio第三代高通量测序技术,对天桃木土壤细菌群落多样性进行了研究,并通过测定土壤化学性质,分析天桃木土壤优势细菌群落与土壤化学因子的关系。结果表明:在门水平上,共存在23门细菌,其中变形菌门Proteobacteria和酸杆菌门Acidobacteriota是4个样地土壤的优势菌门;在属水平上,共鉴定出118属细菌,其中Vicinamibacter、疣微菌属Pedosphaera、硝化螺旋菌属Nitrospira为4个样地土壤的优势菌属;在种水平上,共鉴定出123种细菌,其中酸杆菌Vicinamibacter silvestris、疣微菌Pedosphaera parvula、芽单胞菌Gemmatimonas sp.、土生单胞菌Terrimonas sp.为4个样地土壤的优势菌种。冗余分析结果显示,土壤pH、速效K含量和有效P含量对细菌群落门水平和属水平组成影响较大,土壤pH、有效P含量、全P含量对细菌群落种水平组成影响较大。
    Abstract: In June 2020, 3 typical quadrats were established in 4 research areas in nature growing Mangifera persiciformis in Nanning, Chongzuo and Bose of Guangxi. Soil bacterial community under Mangifera persiciformis was determined by high-throughput sequencing technology, and the soil chemical properties were measured. The results showed that there were 23 phyla, of which Proteobacteria and Acidobacteriota was dominant in the four research areas. A total of 118 genera were identified, of which Vicinamibacter, Pedosphaera and Nitrospira was dominant in the four areas. There were 123 species were identified, of which Vicinamibacter silvestris, Pedosphaera parvula, Gemmatimonas sp. and Terrimona sp. were dominant. Redundancy analysis demonstrated that the available potassium, available phosphorus and pH had great influence on the composition of bacterial phylum and genus levels, and the total phosphorus, available phosphorus, and soil pH had great influence on the composition of species level.
