摘要:
采用16SrDNA高通量测序技术分析杭州临安区正常生长和不良生长状况2种山核桃Caryacathayensis林地土壤真菌群落结构。结果表明,生长不良山核桃林地与正常林地真菌优势类群相同,不同样地中子囊菌门Ascomycota、接合菌门Zygomycota、担子菌门Basidiomycota均为优势类群,但相对丰度不同,正常林地土壤中担子菌门和接合菌门的相对丰度高于生长不良林地。在属的分类水平上,正常林地土壤中小画线壳属Monographella、镰刀霉属Fusarium和土赤壳属Ilyonectria的相对丰度明显低于生长不良林地。生长不良林地土壤真菌多样性高于正常林地,Shannon-Wiener指数,ACE指数,Chao1指数与土壤pH之间呈显著负相关(P<0.05),与有机质、碱解氮和交换性酸显著正相关(P<0.05)。
Abstract:
Soil samples in 0-20cm layers were collected in August of 2016 from six plots at normal and unhealthygrowth Caryacathayensis stands in Lin’an, Zhejiang province.Determinations on chemical properties were implemented and fungi community structure was analyzed by 16SrDNA sequencing.The results indicated that dominantphylums and genera were similar in the two different kinds of soil, including Ascomycota, Zygomycota and Basidiomycota, but relative abundance was different.Relative abundance of Basidiomycota and Zygomycota in normal growth plots was higher than that in unhealthy ones.Relative abundance of Monographella, Fusarium and Ilyonectria in unhealthyplots was higher than that in normal ones.Correlation analysis demonstrated that Shannon-wiener, ACE and Chao1 index had significant negative correlation with pH and positive onewith organic matter, alkaline nitrogen and exchangeable acidity.
