在高大平房仓中运用磷化氢仓外投药环流熏蒸技术进行熏蒸杀虫,能有效解决药剂穿透力和分布速度以及毒气在粮堆中的均匀分布等问题,使用磷化氢环流熏蒸处理的效果优于常规熏蒸处理的效果。但在实际运用过程中,由于仓外投药磷化氢环流熏蒸需要二氧化碳气体作为载体和起防燃爆作用
Circulation fumigation of pesticides using phosphine outside the warehouse in the high warehouse to fumigation insecticide, which can effectively solve the pesticide penetration and distribution speed and the uniform distribution of gas in the grain piles and other issues, the use of phosphine circulating fumigation The effect is better than the effect of conventional fumigation.
