| Abstract: | Soil specimens were collected from rhizosphere and non-rhizosphere soils in five different soil layers(0~10,10~20,20~30,30~40 and 40~50cm) in Populus euphratica forests of different ages in Wulateqian Banner,Dengkou and Ejina Banner.A total of 462 bacteria of 34 genera,307 fungi of 29 genera,and 255 actinomycetes of 23 genera were isolated,among which Micrococcus,Clavibacter and Brevibacterium were the dominant genera in bacteria,Penicillium,Fusarium,Aspergillu and Trichoderma were dominant genera in fungi,... |
