仓房气密性改造与害虫熏蒸防治技术探索

Air Tightness Transformation of Large Size Horizontal Warehouse and Explore Phosphine Fumigation Technology

中央储备粮湖州直属库对部分仓房进行了气密性改造,并对改造后的仓房进行了实仓磷化氢熏蒸防治储粮害虫试验。试验表明:通过实施一系列气密性改造措施,可以显著提高储粮仓房的气密性,延长磷化氢气体较高浓度水平的保持时间,延迟补药时间,甚至无需补药,而最终可以有效杀死仓内的储粮害虫,实现低剂量熏蒸。

The central grain reserves Huzhou depot on the part of the barns were gas tight reform, and real storehouse phosphine fumigation to control stored grain pests test on the transformation of the barns.The experiment results showed that： it can significantly improve air tightness of large size horizontal warehouse,extend the keep time of phosphine in the high level, delay the tonic time even never, effectively killed the grain pets and achieve low dose fumigation in the end during a series of measures about air tightness transformation; in addition, the no insects interval is more than 4 months.
