摘要
本文利用浓度４～１５％的低ＣＯ＿２和剂量为０．６～４ｇ／ｍ￣３的磷化铝对小麦、稻谷进行了混合熏蒸。多次试验表明：用浓度为８～１２％的ＣＯ＿２气体和浓度０．１８ｇ／ｍ￣３的磷化氢气体混合熏蒸能有效地杀死长角谷盗等１２种常见害虫和粗脚粉螨等６种常见螨类及大量为害的书虱，处理后的粮食经渡夏储藏为安全粮。熏蒸２４小时后仓内ＣＯ＿２和ＰＨ＿３达到均匀分布。
Study on mixed fumigation of carbon dioxide at a concentration of 4-15%andaluminium phosphide at the dosage of 0.6-4.0g/m￣3 shows that carbon dioxide can potentiatethe action of phosphine against 12 species of stored grain pests such as Cryptolestes pusillus,Tribolium Confusum and 6 species of nomal mites such as Acalus siro L,A.casalis Berlese.Mixedfumigation of the cabon dioxide at the conentrition of 8-12%with the dosage of 0.18g/m￣3phosphine can effectively control insects and mites.The wheat and paddy treated by mixed fumi-gation has passed unharmfully through the summer,The result of the mixed fumigation also indi-cates that carbon dioxide can accelerete the phosphine infiltration into the bulk grain.The distri-bution of carbon dioxide and phosphine in the storehouse is uniform 24 hours after the mixed fu-migation The mixed fumigation covered with a PVC plastic film on the grain surface produces abetter result in killing the insects than the normal fumigation,and the dose of aluminum phos-phide is reduced by 50%.
