摘　　要：以喜树幼苗为试材,通过温室盆栽接种试验,研究了在不同接种时期接种蜜色无梗囊霉(Acaulospora mellea)对喜树幼苗生长的影响。结果表明:丛枝菌根的形成促进了喜树幼苗的生长,但其促进作用受到接种时期的影响,早期接种菌根真菌(喜树幼苗长出真叶后第0天和20天),更有利于喜树幼苗的生长和对氮、磷营养的吸收。Taking Camptotheca acuminata seedlings as test material, through pot inoculation experiment in the greenhouse,effect of inoculation Acaulospora rnellea on the growth of Camptotheca acuminata seedlings in the different inoculation time was studied. The results showed that the formation of AM promoted the growth of C. acuminata seedlings, but the promotion impact got affected by inoculation time. The AMF was more beneficial to the improvement of the growth and absorbing the nitrogen and phosphorus of seedlings,which were inoculated at early stage （0 and 20 days of seedlings after true leaf stage）.
