2010年上海局部地区水稻条纹叶枯病重发原因与综防探讨
The cause and integrated control of heavy occurrence of rice stripe virus in some areas of Shanghai in 2010
摘要
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 hm2,average rate of diseased plants was 0.66% and the highest was over 20%. The major factors were a large number of Laodel-phax 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.关键词
