摘要
[目的]筛选强拮抗能力强的芽孢杆菌。[方法]从山东莱芜采集病姜及附近土壤中分离出姜瘟致病菌高毒力菌株,并利用芽孢杆菌进行了拮抗试验。[结果]LW-4、LW-7、LW-32这3株菌对姜瘟致病菌有较强的拮抗能力,其抑菌圈面积较其他菌株大。[结论]为防治姜瘟病提供了理论依据。
[Objective] The paper was to screen Bacillus with strong antagonistic effect.[Method] The diseased ginger and the surrounding soils were collected from Laiwu of Shandong Province,and the high-virulence strains of the pathogen of ginger blast（Ralstonia solanacearum） were isolated,Bacillus was used to carry out antagonistic test.[Result] Three strains LW-4,LW-7 and LW-32 had strong antagonistic effect against R.solanacearum,the area of their inhibition zone was larger than other strains.[Conclusion] The study provided theoretical basis for the control of ginger blast.
