病虫害防控是新一轮小麦高产攻关的重要环节。小麦白粉病的防治选用抗病品种和加强品种的抗性布局。这是控制白粉病危害的基础,特别是在越夏区的小麦品种的抗性基因要和临近麦区的抗性基因不同,大面积种植品种的抗性基因和越冬区的抗性基因也要不同。这样形成抗性阻隔布局策略。
Pest control is an important part of a new round of high yield wheat research. Wheat powdery mildew prevention and control use of resistant varieties and varieties to enhance the resistance layout. This is the basis for the control of the hazards of powdery mildew. In particular, the resistance genes of the wheat cultivars in the Yuexia district should be different from the resistance genes in the vicinity of the wheat area. The resistance genes of the large-scale cultivated varieties and the resistance genes of the overwintering areas different. This forms a resistance barrier layout strategy.
