摘　　要：通过菌丝生长速率法测定了6种生物制剂对人参根腐病菌的抑制效果。结果显示,抑制作用由强到弱依次为枯草芽孢杆菌、苏云金杆菌、EM菌肥、解磷菌、嗜热性侧孢霉、哈茨木霉菌。其中枯草芽孢杆菌、苏云金杆菌对人参根腐病菌均具有明显的抑制作用,以枯草芽孢杆菌抑制作用最强,其EC_(50)为0.17mg/L;苏云金杆菌次之,EC_(50)为707 mg/L;EM菌肥、解磷菌、嗜热性侧孢霉、哈茨木霉菌的EC_(50)分别为1 148、3 630、7 943、91 201 mg/L,抑菌效果较差。To determine 6 kinds of biological agents for inhibition effect of ginseng root rot fungus by the mycelium growth rate method.The results showed that the sequence of the inhibiting effect from strong to weak was Bacillus subtilis,Bacillus mucilaginosus,Efective Micro-organisms,Bacillus mucilaginosus,Phosphate-solubilizing microorganisms,Sporotrichum thermophile, Trichoserma harzianum.B.subtili,B. mucilaginosus had obviously inhibitory effect on ginseng root rot fungus. B. Subtilis had the strongest inhibiting effect whose EC50 was 0.17 mg/L. B. mucilaginosus had the second best inhibiting effect whose EC50 was 707 mg/L. The inhibitory effect of Efective Micro-organisms,B. mucilaginosus,Phosphate-solubilizing microorganisms,S. ther-mophile ans T. harzianum were relatively poor, whose EC50 were 1 148、3 630、7 943、91 201 mg/L respectively.
