摘要: 调查了云南省4种植被下土壤真菌总数、木霉数量及种类分布特点.森林土壤中木霉相对数量约占土壤真菌总数的3~15%,并随不同样地、采样季节及土层而异,优势种类因不同林型土壤而异.钩状木霉分布广泛,尤其在热带雨林的土壤生境中占优势.哈茨木霉和黄绿木霉则分别在季风和半湿润常绿阔叶林土壤中出现频率较高.

Abstract: Studies on total soil fungi and abundance and distribution of Trichoderma in different vegetation soils of Yunnan show that relative amount of Trichoderma in forest soil occupies 3~15% of total fungal propagules, and varies with different sites, seasons and soil layers.Dominant species varies with different forest types. T. hamatum is widely distributed in all vegetation soils, especially in tropic rain forest soil. T. harzianum and T. aureoviride are frequently found in monsoon and semi-humid evergreen broad-leaved forest soils, respectively.
