摘要
本次试验针对小麦仓中上层局部生虫问题 ,采用粮堆局部处理机环流熏蒸 ,一次投药 ,总计熏蒸处理 11天。试验证明 :PH3 浓度大于 30 0 ppm能够维持 7天 ,10 0~ 30 0 ppm能够维持 3天。处理部位害虫全部杀死 ,实仓生物试验 ,成虫的死亡率也为 10 0 % ,虫粮经温室培养 4
Partial recirculation fumigation against the insects in upper and middle layer in wheat stored warehouse,was carried out in 11 days and applied only once.The results showed that PH 3 concentration can maintain above 300ppm for 7days,and then 100~300ppm for 3 days.The mortality of adult insects was 100%,and after 42 days no insects was found.
