Abstract: Several AMF species were isolated from Triticum acstivum、Hordeum vulgare、Zea mays 、Setaria italica and Glycine max. Seven species were identified. They were Glomus mosseae、Glomus constrictum、Glomus versiforme、Glomus caledonium、 Glomus aggregatum、Glomus geosporum、Glomus dimorphicum. Infection rate of AM and spore density of different hosts were also measured.
