本文从我国所处的地理位置,结合国外主要水稻病毒病发生流行的动向,联系我国水稻病毒病的实际,历史地回顾并总结了水稻黑条矮缩病和暂黄病六十年代前中期及其以后几次大的流行的主要原因和经验教训;概要地综述了水稻病毒病的现状,介绍了我国发生的11种水稻病毒及类似病害的病原、分布、介体、传播和发生流行的一些关键因素,指出在全国稻区仍以暂黄病和矮缩病的发病面积最大,为害最重。病害在品种间的抗性有显著差异,只有适合流行的年份栽培大量感病品种,遇上大量带毒介体,流行才成为可能。展望未来的5年,
In this paper, from the geographical location of our country, combined with the trend of the prevalence of major foreign rice virus diseases in foreign countries, with the actual and historical history of rice virus diseases in our country reviewed and summarized, The main causes and experiences of several major epidemics in the future; the current situation of rice virus diseases is summarized and the pathogen, distribution, mediator, transmission and occurrence of some 11 kinds of rice viruses and similar diseases occurring in our country are introduced The key factors that pointed out that in the national rice area is still the incidence of Huang Huang and dwarf disease incidence of the largest and most damaging. Disease resistance in different varieties have significant differences, only suitable for popular years cultivated a large number of susceptible varieties, met with a large number of toxic mediators, the epidemic has become possible. Looking forward to the next 5 years,
