实验确定的气相色谱分析方法测定小麦、稻谷、面粉、馒头、大米及米饭中的仓储磷残留回收率皆在90%以上。以15ppm 剂量机械喷雾于储藏稻谷,施药后药剂收率约50%,经12个月储藏期原粮上残留约1ppm,以10ppm 剂量处理小麦,施药后乳剂及粉剂收率分别为50%及65%左右,经12个月储藏原粮上残留2—2.5ppm,在整个储藏期间面粉上残留<2ppm,大米<0.5ppm,馒头<0.5ppm,米饭上为痕迹量。 The gas chromatographic analysis method was used to determine the residual phosphorus recovery of storage phosphorus in wheat, rice, flour, steamed bread, rice and rice all above 90%. 15ppm dose of mechanical spraying in the storage of rice, pesticide yield after application of about 50%, after 12 months of storage on raw grain residue of about 1ppm, 10ppm dose of wheat treatment, the emulsion and powder yield were 50% and About 65%. After 12 months of storage, the remaining 2.5-2.5ppm on the original raw grain, <2ppm of flour, <0.5ppm of rice, <0.5ppm of bread, or traces of rice on the whole storage period.
