环流熏蒸技术是四项储粮新技术之一,现已广泛应用于储粮害虫防治。单一采用仓外磷化氢发生器施药方法,虽能节约大量人力,但操作耗时长,二氧化碳用量大,费用也较高。而采用磷化铝(AlP)粮面施药环流熏蒸和仓外磷化氢发生器补药相结合,能有效地均衡磷化氢(PH3)在熏蒸期间的浓度,确
Circulation fumigation technology is one of four new grain storage technologies, which are now widely used in the prevention and control of stored grain pests. A single use outside warehouse phosphine generator application method, although a lot of manpower savings, but the operation takes a long time, carbon dioxide consumption, high cost. The use of aluminum phosphide (AlP) grain noodles circulation fumigation and warehouse outside the phosphine generator tonic combination, can effectively balance the concentration of phosphine (PH3) during fumigation, and indeed
