云南若干地区土壤放线菌区系及资源考察 X.滇东南地区

The soil samples were collected from primeval forest, secondary forest, wasteland, farmland and vegetable farmland in eight areas of southeastern Yunnan. Actinomycetes in the samples were isolated and identified by various procedures. It is indicated from the results that the population of soil actinomycetes in the southeastern Yunnan is complex, and 13 genera of actinomycetes were isolated; a great variety of actinomycetes in the soil of primeval forest; the rare actinomycetes had a more ratio.
