| 摘 要： | 2001—2006年对天津地区水稻条纹叶枯病的上升原因及灰飞虱发生动态进行了调查研究,并对水稻条纹叶枯病的综合防治进行了探讨。研究表明,冬季出现暖冬,春季和秋季雨水偏少,灰飞虱越冬基数增加,春季繁殖系数增大,虫口密度逐年上升是水稻条纹叶枯病上升的主要原因。通过选用抗病品种,调整播种期和插秧期,结合药剂防治,可控制病害的发生程度。

| Abstract: | The reasons of the increasing of Rice stripe disease and dynamic of small brown rice planthoppers in Tianjin from 2001 to 2006 were studied in the paper. The integrated control of Rice stripe disease was discussed in addition. The results showed that the reason of the increase of Rice stripe disease was the warm winter, the little quality of rain from spring to warm, increasing of the base number of small brown rice planthoppers, the increasing of propagation coefficient in spring, the going up of insect density year by year. The disease can controlled through using the resistant varieties, adjusting sowing dates and seedtime''s and chemical control. |
