大麦网斑病是目前大麦感染较重的一种病害,一般在抽穗后如遇阴雨多湿的天气,常因网斑病大发生,导致上部三张功能叶片早期受到破坏,影响籽粒的饱满程度和制啤酒的工艺品质。大麦网斑病在我国江淮之间和长江以南的大部分冬麦区,以及北方春麦区,因抽穗、灌浆期,雨量较多,湿度较高,温度适宜,发病较重,在年际间常因抽穗后降水量的多少,而表现重发生和轻发生年。因此,为了保证大麦优质、高产、稳产,积极地防治网斑病,使后期功能叶片不受危害或减轻危害,延长灌浆功能,实为一项重要的技术措施。近三年来,我们从大麦 Barley net blotch is currently a serious barley infection, usually in the rainy weather after heading, often due to the occurrence of net blotch, leading to the early destruction of the top three functional leaves affect the fullness of the grain and Process beer beer quality. Barley net blotch in China between the JAC and most of the winter wheat south of the Yangtze River, and the northern spring wheat area, due to heading, filling period, rainfall, humidity, temperature, the incidence of heavier, during the inter-year Often due to the amount of precipitation after heading, and the performance of re-occurrence and light years. Therefore, in order to ensure barley high quality, high yield and stable yield, and actively prevent and control net blotch disease, make late function leaves harm or reduce harm and extend the grouting function, it is an important technical measure. In the past three years, we have been from barley
