摘　　要：文章主要探讨了生产中利用磷化氢环流熏蒸技术对立筒库群进行熏蒸的方法和杀虫效果。试验结果表明 ,该项技术对于立筒仓这类深粮层仓型熏蒸杀虫有很好的效果 ,对仓内的主要害虫有较好的杀死作用 ;但由于仓房气密性、环流方法和设备性能等因素的影响 ,操作不当就不能彻底杀死某些局部虫害或不久又再次发生害虫危害 。The method of PH 3 recirculation fumigation and its effect on insects in silos was probed.The results showed that this technique had efficiency against main insects in such deep granary,like silo.But owing to some factors,such as airtightness of silo,method of recirculation and facility character,the insects in some parts can not be controlled throughly if incorrect operation was adopted.The insects will soon occur again.
