摘　　要：花生根腐病是造成花生严重减产的重要土传病害之一,其病原菌包括尖孢镰孢菌(Fusarium oxysporum)、层出镰孢菌(F.proliferatum)和茄腐镰孢菌(F.solani)。本试验以新鲜大蒜为材料,研究大蒜鳞茎浸提液对3种镰孢菌菌丝生长、产孢量及孢子萌发的抑制作用。结果表明:大蒜鳞茎浸提液对3种镰孢菌均有显著的抑制作用,且随着大蒜鳞茎浸提液质量浓度的提高,其抑制效果越明显,其中对尖孢镰孢菌和层出镰孢菌的防治效果较好。Peanut root rot is one of the most important soil-borne diseases which causes serious yield decrease of peanut.Its pathogens include Fusarium oxysporum,F.proliferatum and F.solani.In this test,we used fresh garlic as material to study the inhibitory effects of garlic bulb extract on hyphae growth,sporulation quantity and spore germination of the three Fusarium species.The results showed that the garlic bulb extract had significant inhibitory effects on the three Fusarium species.With the increase of garlic bulb extract concentration,the inhibitory effect on Fusarium was more obvious,especially on F.oxysporum and F.proliferatum.
