1.选用抗病品种。目前我省推广应用的品种大都不抗白粉病,因此,应以引进国内外抗病品种为主要措施,如白银市农科站从陕西汉中引进的“87加67”,对白粉病免疫,比对照花培764增产2.6％,可推广应用,另外,四川、山西、北京等地科研单位已培育出许多抗白粉病的新品种,可引进试种,进而推广。同时,从长远考虑,我省各级科研单位应注重抗病品种的培育,选育出适合我省种植的抗病丰产 1. Use resistant varieties. At present, most varieties of popularization and application in our province are not resistant to powdery mildew. Therefore, we should take the introduction of domestic and international resistant varieties as the main measures, such as “87 plus 67” introduced by Baiyin Agricultural Science Station from Hanzhong, Shaanxi Province, In addition, Sichuan, Shanxi, Beijing and other scientific research institutes have cultivated many new varieties of resistant to powdery mildew, which can be introduced for trial cultivation and further popularized. In the meantime, in the long term, scientific research institutes at all levels in our province should pay attention to the cultivation of disease-resistant varieties and bred high yield-resistant crops suitable for planting in our province
