摘　　要：研究了河北省蔬菜保护地土壤镰孢菌种群分布情况,分析了棚龄、蔬菜种类、土壤真菌、土壤有机质及速效性化肥对镰孢菌种群分布的影响,鉴定出13种镰孢菌,分别是雪腐镰孢菌(Fusarium nivale)、茄病镰孢菌(Fusarium solani)、水生镰孢菌(Fusarium aquaeductum)、梨孢镰孢菌(Fusarium poae)、拟枝孢镰孢菌(Fusarium sporotrichioides)、弯角镰孢菌(Fusarium campto-ceras)、半裸镰孢菌(Fusarium semitectum)、潮湿镰孢菌(Fusarium udum)、串珠镰孢菌(Fusariummoniliforme)、尖孢镰孢菌(Fusarium oxysporum)、木贼镰孢菌(Fusarium equiseti)、柔毛镰孢菌(Fusarium flocciferum)和双胞镰孢菌(Fusarium dimerum),其中尖孢镰孢菌(F.oxysporum)和茄病镰孢菌(F.solani)是优势种;同时表明土壤等因子对镰孢菌种群的分布有着重要的影响,但规律不尽相同;木霉对镰孢菌的生长有着明显的抑制作用。Fusarium species distribution and its effect factors were studied in the thesis. 13 Fusarium species were identified such as Fusarium nivale ,Fusarium solani ,Fusarium aquaeductum ,Fusarium poae ,Fusarium semitectum ,Fusarium udum ,Fusarium monili forme, Fusarium oxysporum ,Fusarium equiseti ,Fusarium flocci ferum and Fusarium dirnerum. F. oxysporum and F. solani were dorminant species. And there were no obvious regularity between soil factors and numbers and species of Fusarium. But the Trichoderma spp. could inhibit Fusarium oxysporum.
