Ecological effects of arbuscular mycorrhizal fungi on the growth of maize

摘要: 1996～1998年试验研究了大田不施肥条件下3种泡囊丛枝菌根真菌Arbuscular mycorrhizal fungi (AMF)，即 Glomus mosseae(G.m)、Glomus versifome(G.v)、Sclerocystis sinousa(S.s)对玉米生长的生态效应。结果表明，AMF处理的玉米根系活力为对照的2.32～3.05倍，玉米N素吸收比对照增加24.14%～56.65%，玉米P素吸收比对照增加41.14%～78.29%，促进玉米生长发育显著；在灭菌条件下G.m、G.v、S.s处理分别比对照增产17.63%、22.91%和10.80%；而不灭菌条件下3个处理分别比对照增产10.35%、20.56%和4.53%，同时显著提高玉米的水分供应状况。

Abstract: 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.
