摘　　要：利用高效液相色谱对油菜地土壤和油菜植株中的胺苯磺隆残留量进行了检测，同时研究了14．5％胺·吡·草除灵可湿性粉剂在油菜地施用后，胺苯磺隆在油菜地土壤和油菜植株中的残留消解动态。结果表明：14．5％胺·吡·草除灵可湿性粉剂施用后，胺苯磺隆在油菜地土壤和油菜植株中的消解半衰期为4．26～6．29d。这说明胺苯磺隆属易降解农药，对油菜地土壤和油菜植株安全无害，但由于其在油菜地土壤和油菜植株中的残留量与施药时间呈较明显的负指数关系，所以应合理控制施用量。The residues of ethametsulfuron in rape growing soil and rape plants were analyzed by HPLC, and the degradation dynamics of ethametsulfuron in rape growing soil and rape plants after applied 14.5% amine ＂topiramate＂ Benazolin WP to rape fields were also studied. The results showed that the degradation half-life of ethametsulfuron in rape growing soil and rape plants was 4.26-6.29 d. Therefore, ethametsulfuron is a kind of pesticide degraded easily, and it is safe for rape growing soil and rape plants. However, the residues of ethametsulfuron in rape growing soil and rape plants showed an obvious negative exponential correlation with pesticide applying time, the applying dosage of ethametsulfuron should be controlled rationally.
