| 摘 要： | 以压力衰减法测定两个相似的薄膜密封包装玉米垛的气密性、采用PH3和CO2混合熏蒸后PH3和CO2气体浓度在粮垛内的保持情况以及对玉米象、米象和赤拟谷盗3种害虫处理的结果。试验结果表明：PH3和CO2气体浓度在粮垛内保持时间与粮垛气密性呈明显相关性，本试验条件下，可以完全杀死供试害虫。

| Abstract: | The experiments of pressure test and monitoring of phosphine and carbon dioxide concentration,and the effectiveness of killing three insects ( Sitophilus zeamais,S.oryzae,Tribolium castaneum ) were carried out in two stacks of bagged corn which covered on five and six sides with PVC sheeting of 0 18mm thick respectively.The results indicated that the higher the gastightness in the stacks was,the longer the pressure decay and maintaining time of fumigant were.At the conditions of the experiments the tested insects were killed completely. |
