Squat Silos taken positions on the circulation phosphine fumigation insecticidal methods, not only to achieve the purpose of the pesticide control, and effectively reduce the cost of fumigation, a decrease of gas in the fight against the occu pational hazards, and have achieved good results.展开更多
采用粮面投药的方式并结合双侧内环流熏蒸系统,开展了架空式浅圆仓熏蒸试验。通过对不同粮层、粮面空间、出粮口、环流管道进行PH_3浓度检测,着重分析了PH_3在粮堆内分布扩散规律。结果表明:环流熏蒸过程中,PH_3浓度分布均匀,整仓平均...采用粮面投药的方式并结合双侧内环流熏蒸系统,开展了架空式浅圆仓熏蒸试验。通过对不同粮层、粮面空间、出粮口、环流管道进行PH_3浓度检测,着重分析了PH_3在粮堆内分布扩散规律。结果表明:环流熏蒸过程中,PH_3浓度分布均匀,整仓平均浓度与时间变化符合多项式变化规律,7 d^34 d不同粮层PH_3平均浓度与时间呈线性负相关,下降速度在12.12 m L/m^3·d^18.88 m L/m^3·d。展开更多
