摘要
通过抛秧田主要病虫发生动态调查 ,对比插秧田进行分析 ,结果表明 :抛秧有利于纹枯病水平发展 ,而不利于垂直发展 ;有利于稻纵卷叶螟的发生为害 ,而不利于 1代二化螟及稻飞虱的发生为害 ;
Through the investigation on occurring dynamics of the main diseases and insects and by the comparison and analysis between the rice throwing seedlings fields and rice planting seedlings fields,the results showed that rice throwing seedlings had advantages for the level development and disadvantages for the vertical development of the sheath blight. Besides, it had advantages for the occurence of rice beafroller and disadvantages for the first generation of the rice stem borer and rice planthopper. It had little influence upon the rice blast isolates during the year when the rice blast isolates seldom occurred.
