| 摘 要： | 为探明绿色木霉和哈茨木霉的提取物对松枯枝病的抑制作用机制,通过绿色木霉（Trichoderma viride）和哈茨木霉（Trichoderma harzianum）提取物对松枯枝病病原菌（Cenangium ferruginosum Fr.）进行平板表面涂抹法和混合培养基法抑制生长试验,观察松枯枝病病原菌生长情况,结果表明,2种木霉菌的提取物对松枯枝病病原菌均有抑制作用,且效果比较明显,抑制效果最佳的为绿色木霉,病原菌的被抑制率达53.54%,混合培养基法中哈茨木霉菌20%提取物对枯枝病原菌的抑制率高达31.67%。

| Abstract: | In order to ascertain the inhibitory mechanism of extract from Trichoderma viride Trichoderma harzi-anum ,the experiments to inhibit the growth for the extract of Trichoderma viride Trichoderma harzianum on Cenangium ferruginosum by using method of plate mix-cultivation media were conducted .Result shows that ：the extracts of two kinds of Trichoderma spp .all have inhibition on Cenangium ferruginosum and have significant re-sult .T .v iride has the optimal inhibition result ,the inhibition rate of pathogens is 53 .54% ;the inhibition rate of 20%extract of Trichoderma harzianum on Cenangium ferruginosum are 31 .67% . |
