| 摘 要： | 微生物通常是土壤中有机质分解以及养分积累的积极参与者,因此,对林地土壤微生物分析,是森林生态系统中物质循环的重要内容之一。本文仅就两年的调查研究,对其中丝状真菌和固氮菌在三个森林类型林地的分布状况及组成特征进行初步分析。

| Abstract: | This papar reports the number and distribution of Fungi and Nitrogen-fixing bacteria in the tropical forest soils at Jianfengling, Hainan Island. The results show that there are differences in the number of fungi in both different season and different vegetation soils. The most is in the low-temperature season, followed successively by the dry season and the rainy season. The fungus number in tropical semideciduous monsoon forest soil is more than that in tropical evergreen monsoon forest soil and the lest number is in tropical mountain rain forest soil. A number of fungus strains were isolated from the above three types of the forest soils. They were identified to belong to 14 genera or groups. Five of the strains were not classified to genera. Nitrogen-fixing bacteria were not obtained from the soils. |
