摘要
采用平板对峙培养法、对扣培养法和圆盘滤膜法研究绿色木霉和枯草芽孢杆菌对玉竹锐顶镰孢菌的拮抗作用。结果表明:木霉和枯草芽孢杆菌对锐顶镰孢菌菌丝生长具有一定抑制作用,木霉的抑制效果较差,枯草芽孢杆菌的抑制效果较好,其中枯草芽孢杆菌菌株Dc10的抑制作用最强,其非挥发性代谢产物对病原菌的抑制率可达100%。
The antagonistic activity of Trichoderma viride and Bacillus subtilis against Fusarium acuminatum was analyzed by competitive culture,culture on facing each other,and filter membrane culture in disk,respectively.The results indicated that both T.viride and B.subtilis had the efficacy to inhibit the development of mycelium of F.acuminatum.The efficacy of inhibition of T.viride was low,but B.subtilis had strong inhibition capability to F.acuminatum.It was the best for the efficacy of inhibition of B.subtilis Dc10,its inhibition for non-volatile metabolize product could up to 100%.
