摘要
百合枯萎病是甘肃省百合产区近年来新发生的一种重要病害。研究证明,百合枯萎病系由尖孢镰刀菌(Fusarium oxysporum Schlecht.)、串珠镰刀菌(F.moniliform Sheldon)和茄病镰刀菌[F.solani(Mart.)Sacc.]侵染所致。病菌以菌丝体在种球内,或以菌丝体、厚垣袍子及菌核随病残体在土壤中越冬,成为翌年的主要初侵染源。病害的发生与连作、线虫、栽培技术及气候因素等密切相关。多菌灵对此病有显著防治效果。
Lily wilt is an important disease recently spreading on cultivated areas in Gansu Province. This study carried out during 1989-1992 demonstrated that this disease was caused by Fusarium oxyaporum Schlecht. ,F. mmiliforme Sheldon and F. sotani (Mart) Sacc. . The main source of primary infection comes from hypha, akinetes and sclerotiums over-wintering in the bulb, residues of diseased plants and the soil. The prevalence of this disease was closely related with the cropping systems, nematodes, cultivated methods, soil and climatic factors. Carbendazim showed good control effect on this disease.
