云南省西部属横断山脉的南端,该地区内温泉分布十分广泛。云南省的东北部则属中山山原区,是乌蒙山系向北伸延的末端。这两个地区的地貌、气候、植被区系均有很大差异。从上述两个样区的原始森林、次生林、荒地、旱地、蔬菜地、水田采集200份土样,用多种培养基分离和鉴定其中的放线菌,并从中筛选出有用的菌株,研究了上述两地区的土壤放线菌的区系组成及异同。
The western part of Yunnan Province is the southern end of the Hengduan Mountains, where hot springs are widely distributed. The northeastern part of Yunnan Province belongs to the Zhongshan mountainous area, which is the end of the Wumeng Mountain System extending northward. The geomorphology, climate and the flora of these two areas are very different. A total of 200 soil samples were collected from the primary forest, secondary forest, wasteland, dry land, vegetable land and paddy field in the two sampling plots. The actinomycetes were isolated and identified by using a variety of media and the useful strains were screened out. The Floristic Composition and Similarities and Differences of Soil Actinomycetes in the Two Areas.
