摘　　要：采用温室盆栽试验测试5株芽孢杆菌属生防细菌对烟草黑胫病的拮抗作用。结果表明,拮抗细菌芽孢杆菌1205对苗期烟草黑胫病有较稳定的防治效果,其分泌物还有促进烟株生长的作用,经鉴定1205菌株为蜡样芽孢杆菌(Bacillus cereus)。5 Bacillus strains with strong antagonism were selected with a pot experiment simulating to control Phytophthora parasitica var. nicotianae at stage of seedling. The control effects of strain 1205 were relatively high. Secrete of strain 1205 accelerated the growth of tobacco. 1205 was identified as Bacillus cereus.
