摘　　要：利用选择性培养基,对本溪山樱(Cerasus sachalinensis)根际微生物进行了分离、鉴定和分类,分析了不同物候期根际微生物区系的变化.结果表明:从本溪山樱根际分离纯化获得的细菌分别属于15个属,以芽孢杆菌属(Bacillus)、假单胞菌属(Pseudomonas)、黄杆菌属(Flavobacterium)为主;放线菌的7个类群中,以黄色链霉菌属(Flavus)和白色链霉菌属(Al-bosporus)为主;真菌以毛霉属(Mucor)、曲霉属(Aspergillus)和青霉属(Penicillium)为主.本溪山樱不同物候期根际微生物区系不同,落叶期根际微生物区系最丰富,萌芽期较少.By using selected culture media, the microbes in Cerusus 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 being the richest at defoliation stage and the least at budding stage.
