摘　　要：采用生物测定的方法,研究了7种植物不同部位的浸提液对黄芪根腐病的3种主要病原菌的抑制作用.结果表明,不同作物的浸提液对3种镰孢菌的孢子萌发和菌落生长的影响不同,既有抑制作用,也有促进作用.其中小麦、玉米、马铃薯和党参浸提液对3种镰孢菌的孢子萌发和菌落生长的抑制作用较显著,而黄芪根和甘草根浸提液对3种镰孢菌的孢子萌发和菌落生长均表现出不同程度的促进作用.The inhibition of vavious organs of 7 kinds of plant infusion on Astragalus membranaceus root rot is studied using biometric methods. The results show that different species infusion on three of Fusarium spore germination and colony growth performance is different, not only inhibition, but also promotion： of which Triticum aestivurn, Zea mays L. , Solanum tuberosum and Codonopsis pilosula infusion on the three types of Fusarium spore germination and growth of bacteria inhibitory is more significant, while the infusion of Astragalus membranaceus root and Clycyrrhiza aralensis Fisch root to the three of Fusarium spore germination and growth of bacteria show various degrees of promotion.
