前言小麦散黑穗病是我省小麦的主要病害之一,发生普通,危害严重。五、六十年代采用温水浸种方法,基本控制了危害,但七十年代以来,推广的品种多不抗病,又缺少高效的拌种剂,在生产上发生散黑穗病得不到控制,因此小麦散黑穗病又迅速回升,据近年调查全省感病品种平均发病率为3～5％。 Introduction Wheat smut is one of the major diseases of wheat in our province, with ordinary and serious harm. In the 1950s and 1960s, the method of warm water soaking was used to basically control the harm. However, since the 1970s, the varieties promoted were not resistant to disease and lacked efficient seed dressing. The occurrence of casual smut was not controlled in the production. Therefore, scattered smut and wheat quickly picked up, according to the survey in recent years, the average incidence of susceptible varieties in the province of 3 to 5%.
