摘要
新仓的气密测试和熏蒸杀虫试验的结果表明,精心施工的新建仓房,在500 Pa压力下完全可以达到100 s以上的压力半衰期。在有效密闭期间内,该气密标准可以维持仓内较高的熏蒸浓度,有利于杀死全部害虫和避免害虫抗性产生;与原来相比还可以减少一半用药量,大大节约了熏蒸成本。
Tests of pressure decay and fumigation were carried out in a new horizontal storehouse, and the results showed that at 500 Pa of original pressure, pressure half--life of the new one might completely reach above 100 seconds. In a effective fumigation period, the concentration in the storehouse could keep a higher concentration for a longer time, and it could control all kinds of pests effectively and prevent insecticide resistance from development. Moreover, the dosage could reduce half and the fumigation cost was saved greatly than before.
