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 mycor-rhizal 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。
The effects of Arbuscular mycorrhizal fungi (AMF), Glomus mosseae (Gm), Glomus versifome (Gv) and Sclerocystis sinousa (Ss) Ecological effects of growth. The results showed that the root activity of maize treated with AMF was 2.32-3.05 times that of the control, the N absorption of maize increased by 24.14% -56.65% compared with the control, and the absorption of P by maize increased by 41.14% -78.29% compared with the control, which promoted the growth and development of maize; Compared with the control, the treatments of Gm, Gv and Ss increased by 17.63%, 22.91% and 10.80% respectively under the sterilizing conditions, but increased by 10.35%, 20.56% and 4.53% Moisture supply.
