摘要
在不同磷化氢环流熏蒸设备配置条件下采用气化施药法在粮堆中施用甲基嘧啶磷防治储粮害虫。试验结果表明:气化施药法可以使储粮保护剂在粮堆中具有一定的穿透能力,但在粮堆上下层的浓度相差较大,在环流系统效率较好的情况下,粮堆上层1 m多的粮层中药剂浓度可达到全仓平均施药浓度以上。
Pirimiphos-methyl was applicated in grain bulk to control stored-grain insect by gasification application method with different recirculation fumigation facilities. The results showed that the grain protectant can permeate through the grain bulk by gasification application method, but the concentration difference between top and bottom was significant. The concentration under 1 m of the surface of grain bulk was higher than the mean concentration of the whole grain bulk under high efficiency condition of recirculation system.
