蒙古口蘑(Tricholoma mongolicum Imai.)蘑菇圈及其两侧的土壤细菌分布的比较研究

A Comparative Study on Distribution of the Bacteria in Soil Around Fairy Rings of Tricholoma Mongolicum

在内蒙古锡林郭勒草原，蒙古口蘑蘑菇圈及其两侧的土壤中细菌的数量及种类分布有明显差异．产生子实体的出菇圈带中存在两种优势细菌。

In the fairy rings of Tricholoma monglicum in the steppe of NeiMongol,distribution of the bacteria in soil of defferent rings or zones had a significant difference in the number and species. There was two species of bacteria that Bacillus macerans and Acidovorax delafieldii with large amount in the ring of growth the fungus fruits,and there was probably close relation between action of the two species and forming of T.mongolicum
