高温高湿地区充氮气调杀虫效果试验

摘要

在华南高温高温地区,通过对高大平房仓实仓充氮气调,使氮气浓度达到杀虫有效浓度并维持一定时间,从而杀死储粮害虫,实现绿色储粮.分析总结了高温高湿地区充氮气调杀虫效果、经济成本及综合效益.%Nitrogen storage in a large horizontal warehouse has been carried out in South China of high tempera-ture and high humidity, the stored grain insects could be killed by maintenance of N2 effective concentra-tion for a certain exposing time, and green grain storage has realized. The insecticidal effect, economic cost and comprehensive effects were also discussed.
