为提高熏蒸效果 ,减轻保粮人员劳动强度 ,降低熏蒸费用 ,减少熏蒸用药量 ,我库积极进行了一些有益的探索。 2 0 0 4年我库改进熏蒸方式 ,把原先利用仓外投药器施药膜下环流熏蒸改用通风槽投药膜下环流熏蒸 ,通过试验 ,取得了良好的杀虫效果和经济效益。现就具体熏蒸试验情况介 In order to enhance the fumigation effect, reduce the labor intensity of grain-conserving staff, reduce the fumigation costs and reduce the dosage of fumigation, our library has actively conducted some useful explorations. In 2004, our library improved the fumigation method, and the original fumigation under the membrane of the external applicator was changed to fumigation under the membrane of the ventilating trough, which achieved good insecticidal effect and economic benefits through the experiment. Specific fumigation test on the situation now
