羊草草原土壤微生物的数量和生物量

羊草原原土壤微生物数量特征是，细菌数量在名生境中分布的顺序为：拂子茅群落〉杂类草〉榆树疏林〉羊草群落〉碱蓬群落；真菌的分布：榆树疏林〉羊草群落〉杂类草群落〉指子茅群落〉碱茅群落〉碱蓬群落，放线菌为：羊草群落〉发类草群落〉碱茅群落〉碱蓬群落〉指子茅群落〉榆树疏林。土壤微生物生物量在６个植物群落中的大小顺序为：羊草群落〉杂类草群落〉榆树疏林〉拂水茅群落〉碱茅群落〉碱蓬群落，土壤微生物数量在土壤剖面中的

STUDY ON NUMBERS AND BIOMASS OF SOIL MICROORGANISM IN ANEUROLEPIDIUM CHINENSE GRASSLAND

The size features of soil microorganism were studied in this paper. For bacteria the numbers different habitats: Calamagrosts epigeios community >weeds community >the sparse woods of Ulmus pumila >Aneurolepidium chinense community > Puccinellia tenuiflora community >Suaeda glauca community. The order for fungi was: the sparse woods of Ulmus pumila >Aneurolepidium chinense community >weeds community > Calamagrosts epigeios community >Puccinellia tenui flora community > Suaeda glauca community. The order of actinomycetes was: Aneurolepidium chinense community >weeds community >Puccinellia tenuiflora community >Suaeda glauca community > Calamagrosts epigeios community >the sparse woods of Ulmus pumila. The order of soil microorganism biomass in six plant communities was: Aneurolepidium chinense community >weeds community >the sparse woods of Ulmus pumila >Calamagrosts epigeios community > Puccinellia tenuiflora community >Suaeda glauca community. The numoers in vertical distribution of soil microorganism was decreased gradually with the soil depth.
