Colonization of Arbuscular mycorrhizal Fungi from the Rhizospere of Three Legume Species in Maowusu Sandland

The colonization coincide of AMF from different host plants,such as Melilotus suaveolens、Leapedeza bicolor and Astragalus adsurgens,was investigated and its relation to soil factors in Maowusu sandland was analyzed.The experiment separated 28 AMF species of 3 genera,Glomus is dominant genera.The host plants were all colonized by AMF and spore density had obvious difference,but the colonization coincides of AMF had a significant diversity in different host plants and had a different effect on the percent colonization of AMF in different sample sites.Soil available N had a significant correlation with vesicular and total colonization of AMF,its colonization rate may be probably influenced by host plants and AMF.
