上世纪60年代初我国华东和华北地区分别发现了水稻黑条矮缩病和玉米粗缩病,后来都分别发生了2次大流行,同时都以病害防治为目标分别开展了研究,探明了当地病害发生规律,提出了相应的防治方法,获得了不同程度的防病效果。80年代以来,水稻黑条矮缩病的发生报道仅限于华东地区局部地市,玉米粗缩病的发生涉及华北、东北、西北、西南和华中地区13个省市。根据各地对两病病原形态、寄主及症状、介体昆虫及传病特性等方面相似性的报道,提出了我国玉米粗缩病与水稻黑条矮缩病病原异同性问题。经近10年来对两病用生物学和分子生物学方法进行比较鉴定,证明我国玉米粗缩病和水稻黑条矮缩病病原同属水稻黑条矮缩病毒(RBSDV)。同时基本探明了水稻黑条矮缩病在浙江杂交稻区和华北玉米区的再次流行成灾的原因,提出了相应的防治措施.并有效地控制了病害的流行危害。
In the early 60s of last century, black-streaked dwarf disease and maize rough-set disease were found in East China and North China, respectively. Two pandemics were later carried out. At the same time, studies were carried out on the prevention and treatment of diseases respectively, The occurrence of local diseases, put forward the corresponding prevention and treatment methods, access to varying degrees of disease prevention. Since the 1980s, the occurrence of black-streaked dwarf rice in China has been reported only in parts of eastern China. The occurrence of maize rough-shirking involves 13 provinces and cities in North China, Northeast China, Northwest China, Southwest China and Central China. According to the similarities and differences of pathogen morphology, host and symptom, mediator insects and transmission disease in different places, the similarities and differences of pathogen of maize rough-hay disease and rice black-stalk dwarf disease in China were put forward. After nearly 10 years of biological and molecular biology of the two diseases were compared to identify, prove that China’s maize disease and rice black-streaked dwarf disease pathogen belong to the black-streaked dwarf virus (RBSDV). At the same time, the reasons for the recurrence of rice black-streaked dwarf disease in the hybrid rice areas of Zhejiang and North China were basically ascertained, and the corresponding control measures were put forward, and the epidemic hazards of the diseases were effectively controlled.
