近年来,在华东地区发生了水稻黑条矮缩病、条绞叶枯病及普通矮缩病,而且从1965年看,还有迅速发展的趋势,对水稻生产造成很大威胁。这些病害,特别是前两种还能侵害大小麦和玉米。因此,为确保粮食的稳产高产,必须加强对这些病害的防治。现把两年来有关的资料,特别是华东水稻病毒性矮缩病研究协作组的一些调查研究资料,汇集一起并提出防治意见,希望能通过边试验、边防治的实践过程,修改补充,逐步改进。
In recent years, there have been rice black-streaked dwarf disease, bar-striped leaf blight and common dwarf disease in East China. From 1965 to the present, there is also a trend of rapid development, which poses a great threat to rice production. These diseases, especially the first two, can also affect large wheat and corn. Therefore, in order to ensure a steady and high yield of grain, prevention and control of these diseases must be strengthened. Now we put together the relevant information in the past two years, especially some investigation and study materials of the Cooperative Group for Research on Rice Virus Dwarf Disease in East China and put forward the opinions on prevention and treatment. We hope that through the process of trial and control, the course of prevention and treatment will be supplemented and gradually improved .
