摘　　要：甲氰菊酯和辛硫磷及其混合剂分别在土壤中使用后 ,定期取样测定在土壤中残留量。结果表明 ,单剂及混剂甲氰菊酯在土壤中半衰期分别为 17.4和 18.6d ;单剂及混剂辛硫磷在土壤中的残留半衰期分别为 14 .8及 14 .6d。甲氰菊酯和辛硫磷单独使用或混合使用在土壤中的降解规律及降解速率常数没有显著差异。从甲氰菊酯和辛硫磷在土壤中残留角度考虑 ,两者混合使用对环境是安全的。s: After applying of fenpropathrin,phoxim and their mixture in soils, respectively, the residue of fenpropathrin and phoxim was analyzed by gas chromatography. The results showed that residue half time (T 0.5 ) of fenpropathrin in soil were 17.4d and 18.6d. The residue half time (T 0.5 ) of phoxim in soil were 14.8d and 14.6d. There were no remarkable differences between the use alone and the mixed use of fenpropathrin and phoxim. From the residue standpoint, the mixed use of the two insecticides in soil was safety.
