Abstract:

fungi diversity and its effect factors were studied in the thesis. 74 species included 24 genus were identified such as Phytophthora、 Mucor Syncephalastrum、 Chaetomium、 Fusarium、 Acremonium、 Colletorichum、 Penicillium、 Cephalosporium、 Botryotrichum、Myrothecium、Mortierella、Cephalotrichum、Torula、Gliocladium、Myceliophthora、Chrysoporium、Vertillium、Tolypocladium、Humicola、Stachybotrys、Trichoderma and Rhizoctonia .And there are obvious correlation between usable k ,organic nutrition, humidity and soil texture and fungi species and quantity.In particular ,the related coefficient of organic nutrition to fungi species and quantity are 0.976 and 0.960, respectively. But there are no regularity between usable N , P and quantity and species of Fungus.
