摘　　要：通过对信阳地区不同茶龄茶园土壤中根部真菌的调查发现,其多样性明显。从茶树根部分离鉴定出真菌10个属,主要包括青霉属、木霉属和曲霉属三大类群。真菌分布总的趋势是根际多于非根际,而且根际效应(R/S)明显。在茶树根部生境中,微生物区系的组成类群多样,数目众多。The diversity of radical fungi has been investigated in soil of the different age tea gardens in Xinyang. The results shows that ten genera of fungi were identified in the root of the tea tree, mainly including Penicillium, Trichoderma, AspergiUus. The general tendency of fungi distribution is that the microorganism of rhizosphere soil is more than that of Nonrhizosphere soil, the rhizosphere effect（R/S） is obvious. There are various microbial groups in root habitat of in tea tree.
