摘　　要：对脐橙根际土壤细菌进行分离,得到116个土壤分离物。通过对峙试验筛选,共选出16个细菌分离物对炭疽病病原菌有良好的拮抗效果,并对其进行了初步鉴定。根据分离物的理化性质并结合《常见细菌系统鉴定手册》,将QC38、QC61、QC63、QC68四株菌初步鉴定为芽孢杆菌属(Bacillus);将QC8、QC79、QC83三株菌初步鉴定为黄色杆菌属(Xanthobacter);将QC13、QC14、QC30、QC35、QC47、QC87、QC123、QC124、QC129九株菌初步鉴定为假单胞菌属(Pseudom onas)。One hundred and sixteen bacteria were isolated from the navel orange rhizosphere soil. Through the confrontation test, sixteen bacteria were screened which could effectively antagonize against Colle- totrichum gloeosporioides Penz. Based on the physical and chemical properties and the Identification Manual of Common Bacteria＇, QC38, QC61, QC63 and QC68 were preliminary identified as Bacillus spp. ;QC8, QC79 and QC3 were preliminary identified as Xanthobacter spp. ;QC13, QC14, QC30, Qc35, QCA7, Qc87, Qc123, Qc124 and QC129 were preliminary identified as PseucIomonas spp..
