摘要
本文结合防治不同粮温条件下不同储粮害虫的最低磷化氢浓度和熏蒸时间,确定磷化氢熏蒸方案,并在熏蒸过程中监测磷化氢气体浓度,研究熏蒸过程中磷化氢浓度空间扩散分布的规律。将杀虫期间磷化氢气体浓度变化情况与杀虫效果进行关联评价,为磷化铝熏蒸剂在储粮熏蒸中的高效应用提供技术支撑。
In the present study, the phosphine fumigation scheme was determined by investigating the pests’ situation in fumigated granaries, combined with the minimum phosphine concentration and the fumigation time of different species of stored pests under different grain temperatures. The concentration of phosphine gas was monitored during fumigation in order to analyze the spatial diffusion distribution pattern of phosphine concentration during fumigation. In addition, the relevance evaluation between the changes of phosphine gas concentration and the pesticidal efficacy was performed to facilitate the aluminum phosphide fumigant application in stored grain fumigation.
