皖赣滇藏部分土壤中真菌种类的初步调查研究

A Preliminary Investigation in Soil Fungi from Anhui,Jiangxi,Yunnan and Tibet

为给土壤真菌多样性研究提供一些基础资料,本文对安徽、江西、云南、西藏4个省区35份土样分别利用稀释平板法进行了真菌种类的调查研究。结果表明:各地区土壤中真菌数量均很丰富,共得到2683个真菌菌落。其中,青霉属真菌的比例最高,为59.6%;曲霉属真菌次之,为23.41%;而顶头孢属、拟青霉属、粘帚霉属、圆孢霉属等所占比例相对较小。此外,安徽省区土壤中的真菌种类最丰富,其余3省相差不大。

In order to provide some foundational information for soil fungi diversity, the fungi species of 35 soil samples from four provinces in China were investigated by adopting dilution plate methods in the current work. The results showed that the diversity of soil fungi is rich in all samples, up to 2 683 fungal colonies. The population of Penicillium spp. is the highest, accounting for 59.6% of its total, which is followed by As- pergillus （23.41%）, while the occurrence rates of the genus Acremonium, Paecilomyces, Gliocladium and Staphylotrichum fungi resources are small. In addition, the most abundant fungi species of the soils was in- vestigated from Anhui Provinces, and that from other three provinces are almost the same level.
