摘　　要：通过湖南、海南和山东2 a 3地田间试验,采用气相色谱分析法研究了喹硫磷在水稻植株、田水和土壤中的残留消解动态。结果表明,在0.02-5.00 mg/kg添加水平下,水稻植株、田水和土壤中喹硫磷的添加回收率为84.8%-104.9%,相对标准偏差为2.1%-5.0%;喹硫磷在水稻植株、田水和土壤中的消解半衰期分别为0.4-4.2,0.7-1.0和4.0-16.9 d,属易降解农药。By the gas chromatograph method, the dissipation dynamics of added quinalphos in rice, paddy water and soil were studied in Hunan, Hainan and Shandong provinces under field experimental conditions for two years. The results showed the average recoveries of added quinalphos were 84.8% - 104.9% with the relative standard deviations of 2.1% - 5.0% under the addition rates of 0.02 - 5.00 mg/kg. The half life of quinalphos was 0.4 - 4.2 d in rice plants,0.7 - 1.0 d in paddy water and 4.0 - 16.9 d in soil, indicating that quinalphos is an easily degradable pesticide.
