摘　　要：采用磷化铝动态潮解膜下环流熏蒸较好地解决了高大平房仓气密性不足、熏蒸效果不理想的问题。试验证明不仅提高了防治效果,降低了熏蒸药剂量,节省了费用,还能使磷化氢气体在粮堆内实现快速均匀分布,具有PH3有效浓度维持时间最长、CT值最大、PH3浓度的连续性和杀虫效果最好的优点。The technology of recirculation fumigation under film could solve the problems of poor airtightness of large horizontal warehouse and poor effect of fumigation.The test improved has the control effect,lowered the dosage of fumigants,saved the cost.Phosphine in grain bulks realized the fast and even distribution.It also had lots of advantages,such as the longest time for effect phosphine concentration maintenance,the maximum CT value,the best persistance of phosphine concentration and excellent effect of pests control.
