重点对自行设计开发的磷化氢、二氧化碳混合钢瓶剂型（２：９８Ｗ／Ｗ）仓外投药的车载钢瓶施药装置、用于仓内使熏蒸气体分布均匀的环流熏蒸装置、用于检测仓内磷化氢浓度的气体取样装置以及选用的磷化氢检测仪进行了实仓实验。结果表明，该设备安全可靠，使用方便，熏蒸用药量较少，杀虫彻底，在平房仓和筒仓熏蒸中均取得良好效果，用于高大粮堆和筒仓熏蒸杀虫时更具优越性。
Focus on the design and development of their own phosphine, carbon dioxide mixed steel bottle dosage (2: 98W / W) outside the cast administration of the cylinder feeding device for the warehouse so that fumigation gas distribution fumigation circulation device is used to detect the warehouse Gas concentration of phosphine gas sampling device and the selected phosphine detector was real warehouse experiments. The results show that the device is safe and reliable, easy to use, less dosage for fumigation, complete insecticide, good effect in fumigation of silos and silos, and superiority in fumigation and insecticide of tall grain piles and silos .
