摘　　要：为预防苗期病害的发生,选择土壤消毒、种子消毒及不同辣椒品种三个因素进行正交试验设计,探究不同处理组合对辣椒灰霉病的防治效果。结果表明:三处理因素对辣椒幼苗灰霉病发病率及病情指数具有一定抑制效果,其中土壤消毒方式影响最大,因此选择合适的土壤消毒方式可有效抑制辣椒灰霉病的发生。In this paper,orthogonal experiments with the factors of soil disinfection,seed disinfection and pepper variety were carried out to investigate their preventive effects on gray mold incidence in pepper seedlings.The results showed that the three factors had inhibitive effects on the incidence and disease index of gray mold in pepper seedlings,whereas soil disinfection had the most positive preventive effect.Therefore,soil disinfection can be used to prevent the gray mold incidence in pepper seedlings.
