摘　　要：本研究采用Illumina MiSeq高通量测序技术,对河北承德栽培和野生北苍术根区土壤AM真菌群落多样性的差异和群落组成进行了检测,同时解析了土壤养分因子对AM真菌群落多样性的影响。结果显示,北苍术根区土壤中检测的AM-OTU分属于1门1纲5目6科8属AM真菌。野生北苍术AM真菌群落由球囊霉属(77.20%)等组成;栽培北苍术由巨孢囊霉属(34.48%~47.20%)、球囊霉属(30.05%~53.7%)等组成;土壤有机质、pH、有效磷、有效钾与AM真菌多样性指数Shannon、Simpsoneven呈正相关,其中有机质对AM真菌群落多样性影响最大。硼与AM真菌多样性指数Shannon、Simpsoneven、Sobs均呈正相关,铁、铜、锰、锌与之呈负相关。本研究阐明了野生与栽培北苍术根区AM真菌多样性及优势菌群差异,揭示了土壤养分因子与其多样性间的关系,为AM真菌在北苍术仿野生栽培中的应用提供了理论依据。In this study,the diversity and community compositon of AM fungi in root-zone soil of wild and cultivated Atractylodes chinensis(Chengde,Hebei province)was detected by the high throughput sequencing technology,and revealed the correlation between AM fungi diversity and nutrient factors.The results showed that the AM-OTU obtained from the root zone soil of wild and cultivated Atractylodes chinensis belonged to 8 genus,6 families,5 orders,1 class,1 phylum.The dominant AM fungi community of wild Atractylodes chinensis was composed of Glomus(77.20%),etc.,The cultivated Atractylodes chinensis was composed of Gigaspora(34.48%-47.20%)and Glomus(30.05%-53.7%),etc..Canonical correspondence analysis(CCA)showed that soil organic matter,pH value,available phosphorus,and available potassium were positively correlated with the Shannon index and Simpsoneven index of the AM fungal community,and organic matter showed the greatest impact on the diversity of the AM fungal community.The element B was positively correlated with the Shannon index,Simpsoneven index,and Sobs index of AM fungal community,and iron,copper,manganese,and zinc are negatively correlated with it.The results of this study interpreted the diversity of AM fungi and the difference of dominant fungi between wild and cultivated Atractylodes chinensis,revealed the relationship between soil nutrient factors and their diversity,which provided a basis for the application of AM fungi in wild-type cultivation of Atractylodes chinensis.
