| 摘 要： | 近几年水稻条纹叶枯病(Rice stripe virus简称RSV)自然发生程度严重,通过实施综合防治措施,病害得到了有效控制.而2010年在局部又出现重发,上海市发生面积约12 093.33 hm2,平均病株率0.66％,严重田块病株率达20％以上.主要因素是灰飞虱发生量大、带毒率高、麦田和绿肥田混茬种植、一代灰飞虱成虫迁移峰期与水稻苗期吻合期长等.根据发生因素分析,提出了麦收后及时耕翻和灌水、适当推迟播期、避开稻麦共生等综防措施. |
| 关 键 词： | 水稻条纹叶枯病 综合防治 灰飞虱 |

| Abstract: | The natural occurrence of rice stripe virus(RSV)in Shanghai,being heavy in recent years,was effectively controlled through integrated prevention and control measures.However,it was heavy again in 2010 in some areas where the total area was 12 093.33 hm~2,average rate of diseased plants was 0.66%and the highest was over 20%.The major factors were a large number of Laodelphax striatellus,a high rate of media carrying the virus,mixed planting of wheat and green manure crops,and a quite long coincidence period between the migration peak of first generation L.striatellus adults and the rice seedling stage.According to the factor analysis,integrated control measures were proposed,including timely plowing and irrigation after wheat harvest,appropriately putting off seeding date,avoiding symbiosis of rice and wheat,etc. |
| Keywords: | Rice stripe virus Integrated control Laodelphax striatellus |
