[目的]探讨黄芩白粉病在河北承德的发生规律,并用不同肥料、不同药剂对黄芩白粉病进行处理。[方法]田间实地观察记载黄芩白粉病的发生规律,结合施肥、施药处理。[结果]黄芩白粉病主要为害叶片和果荚,病菌以菌丝体和闭囊壳在黄芩病残体上越冬,发病高峰期在8月上旬～9月中旬;多晴少雨有利此病发生发展。黄芩白粉病主要为害叶片和果荚,施用尿素有利于发病,施用磷酸二氢钾、复合肥可减轻发病;40%氟硅唑EC10000倍液防治黄芩白粉病效果最佳,防效达87.33%。[结论]为生产区有效地防治黄岑白粉病提供理论依据。
[Objective] The research aimed to discuss the rule of occurrence of Scutellaria baicalensis Blume in Chengde, Hebei Province, and treat Scutellaria baicalensis with different fertilizers and different medicaments. [Method] The field observation recorded the occurrence of Scutellaria baicalensis powdery mildew, combined with fertilization and pesticide application. [Result] Scutellaria baicalensis cv. Phyllostachys praecox mainly damage leaves and pods. The mycelia and the closed shell of the Scutellaria baicalensis ssp. Cristata were overwintered on the Scutellaria baicalensis fali.
