尖峰岭位于海南岛西南部,植物生长茂密,树种繁多,植被和土壤类型的垂直带谱明显,保存着较为完整的热带森林。因此,研究尖峰岭热带林生态系统的物质循环和了解放线菌在不同生态环境中的分布,对合理利用和开发热带森林资源,更好地发挥经济效益,具有重要意义。 1982—1983年,笔者对尖峰岭热带林三种不同森林类型土壤放线菌数量和组成特性作了调查,放线菌培养采用高泽氏一号琼脂培养基,链霉菌类群鉴定根据《链霉菌鉴定手册》,有关林地概况、土壤样品采集时间和方法见初报Ⅰ。
Located in the southwest of Hainan Island, Jianfengling has rich plant species and many species, and the vertical bands of vegetation and soil types are obvious, preserving more complete tropical forests. Therefore, it is of great significance to study the material circulation and understand the distribution of actinomycetes in different ecological environments in Jianfengling tropical forest ecosystem, which is of great significance to the rational utilization and development of tropical forest resources and better economic benefits. From 1982 to 1983, the authors investigated the quantity and compositional characteristics of soil actinomycetes in three different forest types of Jianfengling tropical forest. The actinomycetes were cultured with high Zeiss agar medium. The identification of Streptomyces Identification Manual ", the general situation of forest land, soil sample collection time and method, see the first report Ⅰ.
