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 INVESTIGATIONS ON ACTINOMYCETE POPULATION AND RESOURCES IN SOME AREAS IN YUNNAN X.ACTINOMYCETE POPULATION IN SOUTHEASTERN YUNNAN

从云南省文山、红河等地采集不同植被、不同海拔高度的土壤样品,用不同方法分离高温、中温放线菌,按国内外通用的方法进行鉴定。滇东南地区的土壤放线菌种类丰富,分离到了13个菌属,稀有放线菌的数量所占比例较高。原始森林中的放线菌种属最丰富。本文对该地区放线菌的生态分布进行了探讨。

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.
