Test on Recirculation Fumigation under Plastic Sheet in Squat Silo

摘要

To improve the sealing performance of squat silos, an experiment on recirculation fumigation under plastic sheet in squat silo was made at Daminggong Grain Depot. Comparing with the common recirculation fumigation technologies, it has more advantages, such as the fumigant concentration balance being reached in shorter time, maintaining a high enough dosage for sufficient time, good cost benefit and the chance of infesting insects again being reduced.
