硫酰氟熏蒸在砖圆仓应用效果评价研究（网络首发、推荐阅读）

为探索砖圆仓硫酰氟熏蒸杀虫和防护效果，分别在3个不同气密性仓房，分别采用整仓不环流熏蒸和环流熏蒸，以及采用不同的熏蒸药剂浓度，通过分析比较气体均匀性，浓度保持时间和杀虫防护效果进行评价。试验结果表明，硫酰氟气体可在4 h内自然扩散穿透10 m粮堆，并在24 h内达到整仓气体均匀。环流熏蒸由于环流管道老化造成药剂损失，气体浓度保持时间短。5 g/m3的药剂浓度即可实现较好的快速杀灭4种主要储粮害虫的效果。

Research on the Effectiveness of Sulfuryl Fluoride Fumigation in Brick Silo(Online First, Recommended Article)

To investigate the insecticidal and protective effectiveness of sulfuryl fluoride fumigation in brick silos, three warehouses with different air-tightness were used for evaluation by analyzing gas uniformity, concentration retention time and insecticidal effects. Whole warehouse non-circulation fumigation and circulation fumigation were adopted with different fumigation concentrations applied. The experiment results show that sulfuryl fluoride gas can naturally diffuse thoroughly through a 10 m grain pile within 4 hours, and achieve uniform gas in the entire warehouse within 24 hours. However, circulation fumigation caused a large amount of chemical loss and the concentration retention time was comparatively short. Results also prove the concentration of 5 g/m3 can achieve a desired and rapid killing effect of 4 main types of pests in stored grains.
