摘　　要：从定西市4个生态区豌豆田土样中分离到立枯丝核菌、粘帚霉、茄病镰刀菌、茄病镰刀菌蓝色变种、拟丝孢镰刀菌、半裸镰孢、单隔镰孢等7种豌豆根腐病致病菌。在室内条件下对4个生态区豌豆田土样进行根腐病预测,结果表明,陇西县福星镇杨寨村最重,通渭县华家岭乡老站村次之,安定区宁远镇李塘村第3,定西市农业科学研究院试验农场最轻。The seven kinds of pea root rot pathogens was isolated from soil sample of four ecological zones of pea field in Dingxi city which Rhizoctonia solani Kühn,Gliocladium Corda,F. solani,F. solani var. coeruleum、F. trichothecioides、Fusarium semitectum、Fusarium dimerum. Under laboratory conditions,the root rot disease of soil samples of 4 ecological zones pea field was predicted. The results showed that Yangzhaicun,Longxi county Fuxing town was the most important condition. Secondly,Laozhancun,Tongwei county Huajialing township. Thirdly,Litangcun,Anding District Ningyuan town,the experimental farm of Dingxi Institute of Agricultural Science was the most light.
