【摘要】 “95-8”为较易感白粉病的小麦品系。拔节期见病,孕穗期发展迅速,大发生年能侵害麦穗,病害每上升一个等级,产量多损失9.18％,白粉病对每穗粒数影响最大,对粒重也有较大影响。防治该品系白粉病的技术要点是:大发生年应在孕穗初期和抽穗扬花期确保单独防治2次;普通发生年在孕穗初期和抽穗杨花期防治1～2次。更多还原

【Abstract】 95-8 wheat line was rather susceptible to powdery mildew. Powdery mildew occurred at the wheat jointing stage and quickly developed at the booting stage. When powdery mildew occurred heavily the disease could damaged the wheat ears. The wheat yield loss increased by 9.18% every one level the disease raised. The disease affected the grains per wheat ear the most and also had a rather influence on the 1000-grain weight. In order to control the disease, agents should be generally applied for one or two times at the beginning of booting stage and at the heading and flowering stage, and when the disease occurred heavily agents should be indepently applied two times respectively at the beginning of booting stage and at the heading and flowering stage.更多还原
