Abstract: 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.
