Ecological effects of arbuscular mycorrhizal fungi on the growth of maize

Ecological effects of Arbuscular mycorrhizal fungi (AMF)，Glomus mosseae(G.m)，Glomus versifome(G.v)，Sclerocystis sinousa(S.s) on the growth of maize were investigated on non-fertilizer field in 1996～1998.The results showed that the root vigor of maize plant treated by AMF was 2.32～3.05 times as much as the control.The amount of absorption on N and P was increased by 24.14%～56.65% and 41.14%～78.29%,and the plant growth and development of maize were obviously enhanced.The inoculation with G.m、G.v and S.s could increase the maize yield by 17.63%，22.91% and 10.80% compared with the control in sterilizing soil,and 10.35%，20.56%，4.53% in non-sterilizing soil respectively.The treatment with AMF could obviously improve the condition of water suppliment in maize.
