摘要
从青藏高原的土壤样品中分离到1株新生防放线菌AL-04,其产生的活性物质对多种植物病原真菌和细菌有较强的抑制作用。草莓田间防效试验结果表明:该生防菌剂采用蘸根处理的草莓发病率显著低于不蘸根的对照,防治效果高达84.8%,表现出较强的防病作用;同时还发现蘸根处理的草莓植株健壮旺盛,根系较对照明显发达,干重比高达2倍,表现出很强的促生作用。
A new biocontrol actinomycete strain AL-04 was isolated from a soil sample collected in Qingzang Plateau. It produces a new antibiotic, with a strong inhibition against phytopathogenic fungi and bacteria. Farm experiment of AL-04 showed that incidence of a disease of strawberries that were treated by dipping root was smaller than that of control significantly. Its biocontrol effect was 84.8% high, which showed a strong immune effect. Furthermore it was discovered that trunk of strawberry by the treatment growed healthier and better than that of control, Also roots of strawberry was more developing than that of control. Its dry-mass was 2 times high as that of control, which showed a quite strong growth promoting effect.
