摘　　要：通过对福建省漳洲、福州等地豌豆不同生育期的根腐病原进行调查,基本明确了福建豌豆根腐病的病原。分离鉴定结果表明,福建省豌豆根腐病主要是由茄镰刀菌[Fusarium solani(Mart.)Sacc.]、尖孢镰刀菌(Fusariumoxysporum Schtesht.)、立枯丝核菌(Rhizoctonia solani Khn)、终极腐霉(Pythium ultinum Trow.)、根腐丝囊霉(Aphanomyces euteiches Drechs.)、根串珠霉[Thielaviopsis basicola(Berk.et Br.)Ferr.]和一种未鉴定镰刀菌(Fusarium spp.)等复合侵染引起的;致病性试验表明,茄镰刀菌和根腐丝囊霉对豌豆具有较强的致病力。The pea root diseases at different stages in Fujian Province were investigated. The results showed that the diseases were caused by complex pathogenic fungi belonged to Fusarium solani (Mart. ) Sacc. , Fusarium oxysporum Schlesht. , Rhizoctonia solani Kuhn. Pythium ultinum Trow. , Aphanomyces euteiches Drechs. , Thielaviopsis basicola (Berk, et Br. ) Ferr. and Fusarium spp. The results of inoculation and re-inoculation experiments proved the Fusarium solani (Mart. ) Sacc. and Aphanomyces euteiches Drechs. had a higher virulence than others.
