磷化氢环流熏蒸生产性应用研究

Application of circumfluent fumigation with phosphine

以高大房式仓散存硬麦为实验对象,运用磷化氢环流熏蒸装备,分别采用仓外施药、仓外与粮面施药相结合、仓外与粮面间歇投药法不同方式生产性应用。根据不同区域和厂房条件,可以制定经济、安全、有效的熏蒸工艺,节省熏蒸时间,且浓度均匀,杀虫效果好。

The technique of phosphine circumfluent fumigation was applied to wheat stored in high large warehouse.The test included three modes of apply drug,outside warehouse,combination of outside warehouse with grain surface and combination of outside warehouse with apply drug on grain surface intermittently.Different technique is chosen for different conditions,which is not only economic,safe and effective,but also saving time,concentration uniformity,and good effect in killing insect.
