摘　　要：采用平板对峙法和相对抑菌效果来判别真菌拮抗能力的大小,筛选出对蓝变菌株抑制效果显著的菌株,试验结果表明:所选的10种拮抗菌(6种慢速生长菌和4种快速生长菌)对蓝变真菌(Ophiostoma penicillatum)都有不同程度的抑菌作用,拮抗效果最佳的菌株有Fusarium tricinctum、Gibberella moniliformis和Hypocrea lixii,相对抑制率分别为34.7、6.77和0.36(60 h),所筛选出的拮抗菌株都具有潜在的生物防治开发前景。We adopt the methods of tablet standoff and relative bacteriostatic effect to distinguish the ability of antagonisting, and Fungi with obvious and significant effects on Sapstain Fungi were screened. The results demonstrate that 10 antagonistic fungi have different control degree on Ophiostoma penicillatum, and that Strains Fusarium tricinctum, Gibberella moniliformis and Hypocrea lixii have significant inhibition effects on strain C3 growth-the relative antagonistic effects are 34.7,6.77 and 0,36 （60 hours after antago- nistic culture）,respectively.Strains which are screened out have a potential prospect of biological preservation.
