摘要
Abstract
[Objective] The aim was to explore biocontrol effects of ginseng rust rot by two strains of Streptomyces spp.. [ Method] The antagonistic action of two strains of Streptomyces spp. Selected from rhizosphere of ginseng on Cylindrocarpon destructans was studied by indoor antagonistic test. The control effect of two strains of Streptomyces spp. Against ginseng rust rot as well as effects of two strains of Streptomyces spp. On the yield and growth of ginseng were studied by field biocontrol test. [ Result] The two strains of Streptomyces spp. Both had stronger inhibition to Cylindrocarpon destructans. After the two strains of Streptomyces spp. Were applied, disease indexes of ginseng rust rot both significantly decreased (P < 0.01) ,and their control effects reached 41.94% and 44.28% ,respectively. Compared with control,the yield of ginseng treated by two strains of Streptomyces spp. Were higher,but the difference was not significant. The two strains of Streptomyces spp. Had no significant effect on the survival rate of ginseng seedings and plant growth. [Conclusion] The research provides theoretical basis for studies on the biocontrol of ginseng rust rot.关键词
