小麦黄矮病是1960年以后被注意到的一个新问题,1964年经初步试验研究证明是由麦蚜类所传播的一种病毒病害。目前已知在我国北方麦区都不同程度的有所发生和分布,而西北各省区发生范围较广,发生频率较高,为害较严重。冬、春小麦在各个阶段都可感染黄矮病,受病小麦一般叶片呈姜黄色变,植株有不同程度的矮化,养分合成和积累的功能降低,因而造成减产。但色变、低矮、减产的程度和情況
Wheat yellow dwarf is a new problem noticed after 1960, and preliminary pilot studies in 1964 proved to be a viral disease transmitted by wheat aphids. It is known that the occurrence and distribution of wheat fields in the northern part of our country are all occurring in varying degrees. However, the occurrence and distribution of wheat fields in the northwestern provinces and regions are relatively wide, with a high frequency and serious damage. Winter wheat and spring wheat are susceptible to yellow dwarf disease in all stages, and the general leaves of the affected wheat are turmeric-like, the plants have different degrees of dwarfing, the functions of nutrient synthesis and accumulation are reduced, and the yield is reduced. But color change, low, the extent and circumstances of the reduction
