[Microbial flora in Cerasus sachalinensis rhizosphere].

By using selected culture media, the microbes in Cerasus sachalinensis rhizosphere were isolated, identified and classified, with their community structure and dynamic changes at different growth stages of C. sachalinensis studied. The bacteria isolated were belonged to 15 genera, among which, Bacillus, Pseudomonas and Flavobacterium were the dominant ones. Flavus and Albosporus were the two dominant genera in seven groups of Actinomyces, and Mucor, Aspergillus and Penicillium were the main genera of fungi. The microbial flora varied with C. sachalinensis growth stage, being the richest at defoliation stage and the least at budding stage.
