摘要
从猕猴桃根际土壤中分离到的115株芽孢杆菌中,经过皿内拮抗活性试验筛选到12株对猕猴 桃细菌性溃疡病有较好抑制效果菌株。进一步单胞分离纯化后,拮抗活性明显增强,尤以B17-4、B56-1 和B56-3效果显著。田间药效试验表明:B56-3菌株发酵滤液稀释500倍时,采用刮除病斑涂抹法防治 效果达到88％。
Twelve antagonistic strains, which inhibit the pathogen of kiwifruit cancer disease seriously, were screened out from rhizosphere soil. Activity of biologic inhibition was enhanced obviously, after purified by single-cell isolation. Especially, B17-4, B56-1 and B56-3 were obvious. The result of field trial showed that control effect could get to 88%, by getting rid of infected tissue with smearing, when the filtration of B56-3 fermentation was dilute 500 times.
