摘　　要：本文对兴安杜鹃菌根形态、侵染情况进行了初步研究。观察到的兴安杜鹃菌根形态特征比较复杂,既有典型的杜鹃花类菌根(ERM)特征,即菌丝节、菌丝团和菌套,也有细胞内贯穿菌丝、根上菌丝网、根表面的游走菌丝和降解的菌丝,在少数根样中还有典型的丛枝菌根(AM)特征,即泡囊的存在。兴安杜鹃菌根侵染率8月较高6,月和9月较低。用SPSS统计软件进行兴安杜鹃菌根侵染率与土壤理化性质相关性分析,结果表明菌根侵染率与土壤的理化性质相关性不显著。The mycorrhizal morphology and colonization rate of Rhododendron dauricum were surveyed.Mycorrhizal morphology observed is more complex.There are typical ericoid mycorrhiza（ERM）feature.But there are fewer typical arbuscular mycorrhizal（AM） feature in a few root samples,namely the vesicles.The Mycorrhizal colonization rate is higher in August,lower in June and September.The correlation between the mycorrhizal colonization rate and chemical properties of soil were not significant.
