摘要
通过Trichoderma属 3个菌株与樟子松枯梢病菌 (Sphaeropsissapinea)对峙培养试验的结果表明 :Tri chodermaviride1,Trichodermaviride 2及Trichodermaharzianum对樟子松枯梢病病原菌都有抑制效果 ,其中Trichodermaviride 2对病原菌的相对抑制效果最好 ,且其相对抑制效果随着时间的增加而增长 ,在 4 0h达到最高 ,为 73.5 5。Trichodermaviride 1和Trichodermaharzianum对病原菌的相对抑制效果在 16h达到最高 ,分别为 4 .86及 2 .5 9。
The antagonistic experiments between Trichoderma spp. and Sphaeropsis sapinea showed that Trichoderma viride 1, Trichoderma viride 2 and Trichoderma harzianum could be used as antagonistic fungi to Sphaeropsis sapinea for biological control. Trichoderma viride 2 had the best depressing effect on Sphaeropsis sapinea. The depressing effect increased with time, and it reached to 73.55 at 40 hours. The depressing effects of Trichoderma viride 1 and Trichoderma harzianum achieved the highest at 16 hours, and they were 4.86 and 2.59, respectively.
