摘　　要：为了彻底杀灭不同虫期的储粮害虫,防止害虫交叉感染,避免重复熏蒸,保障广东省储粮安全,本文通过对包装小麦采用聚氯乙烯薄膜六面密闭的方式研究磷化氢释熏蒸技术,一次投药,控制药剂反应速度,使其缓慢均匀释放。然后,通过试验对比磷化铝常规熏蒸和缓释熏蒸。结果表明,采用六面密闭的方式,在保证密闭的情况下,常规熏蒸和缓释熏蒸均能达到良好的杀虫效果,保证小麦不因虫害而影响粮温变化。相比常规熏蒸,经过60d的低剂量缓释熏蒸后,磷化氢平均浓度保持在285mL/m^3,能有效延缓磷化氢浓度变化,减少用药量,为磷化铝安全高效熏蒸提供技术保障。In order to completely different insect pests,and prevent cross infection o£pests,avoid repetition and fumigation,ensure the security of grain storage in guangdong province,this article through to the packaging of wheat with the method of polyvinyl choride(PVC)six sides sealed,the phosphine slow-release fumigation technology,a drug delivery,controlled drug reaction speed,make its slow release.Then the conventional fumigation and the slow-release fumigation of aluminum phosphide were compared through experiments.The results showed that the conventional fumigation and the slow-release fumigation could achieve effective insecticidal effect under the condition that the six-side airtight was ensured,and the grain temperature change was not affected by insect pests.Compared with conventional fumigation,after 60 days o£low-dose slow-release fumigation,the average concentration of phosphine is maintained at 285mL/m3,which can effectively delay the change of phosphine concentration,reduce the amount of drug used,and provide technical guarantee for safe and efficient fumigation of aluminum phosphide.
