摘　　要：利用气相色谱法检测了推荐剂量下30%莎稗磷乳油在福建稻田系统中的残留动态及最终残留量.结果表明,莎稗磷在稻田水、土壤、稻叶以及稻茎中的半衰期分别为1.36、1.37、1.41和1.34 d;收获时在稻秆、稻米、稻壳、水中均未检测出莎稗磷,在稻田土壤中有痕量的莎稗磷被检出.The residue and dynamic degradation of 30% Anilofos EC in paddy field system were investigated under recommended dosage by gas chromatography （GC）. The result showed that the half lives of Anilofos in water and soil of paddy field, rice leaves and r^ce stalks were 1.36, 1.37, 1.41 and 1.34 days respectively. No residual Anilofos was detected in samples of haulms, rice, rinds and water, but trace Anilofos was found in soil when harvest.
