【摘要】 小麦条锈病已成为威胁四川省小麦安全生产最重要的病害。探讨条锈病的有效控制措施,为病害的综合治理提供技术支撑,具有特别重要的意义。本研究通过对6个不同抗性水平的小麦品种进行不同组合的混播,系统调查了各品种净作和多品种混播田小麦条锈病的病情发展动态。试验表明4个或6个品种混播能推迟条锈病发病期、延缓发病速率、降低发病程度,而且具有较好的稳产作用。更多还原

【Abstract】 Wheat stripe rust became the most important disease to threaten wheat’s safe yield in Sichuan province.To study available control measures and provide technique supports for the integrate control of the disease,systematic surveillances to the development of the disease in different fields planting different varieties and variety mixtures was conducted.It was revealed that planting of four or six variety mixtures with different resistant level could put off the date of appearance of wheat stripe rust,slow down spread speed and decrease the disease degree.And at the same time,planting of four or six variety mixtures could ensure high yield of wheat.更多还原
