摘　　要：在香榧、山核桃、杨梅等控根容器苗培育过程中,选用固氮菌、解磷菌及其混合菌进行菌肥试验。结果表明:施菌肥3 a后,香榧容器苗解磷菌、混合菌处理苗高生长量比对照分别增加18.26%和18.06%,差异显著(P<0.05);山核桃容器苗固氮菌、混合菌处理高生长量比对照分别增加46.25%和47.23%,差异显著(P<0.05);杨梅容器苗混合菌处理苗高生长量与对照相比差异显著(P<0.05),明显优于它们单独使用效果;此外,不同菌肥对香榧等3种苗木地径生长也有一定的促进作用。由于不同的菌肥对各树种的苗木生长促进效果有明显差异,在苗木培育过程中,应根据不同的苗木合理选用菌肥。Experiments were conducted on application of microbial fertilizers like nitrogen fixing bacteria,phosphate-dissolving bacteria and mixed bacteria on root-pruning container seedling cultivation of Torreya grandis cv.Merrillii,Carya cathayensis,Myrica rubra.The result showed that after 3 years test,height growth of container T.grandis cv.Meirrillii seedlings treated by phosphate-dissolving bacteria and mixed one increased 18.26% and 18.06% than that of the control,with great difference（P0.05）.Height growth of container C.cathayensis seedlings treated by nitrogen fixing bacteria and mixed one increased 46.25% and 47.23% than that of the control,with great difference（P0.05）.Height growth of container Myrica rubra seedlings treated by mixed bacteria had significant different with that of the control and was better than that treated by the other two fertilizers.
