| 摘 要： | 通过田间试验,采用气相色谱法分析研究了溴虫腈在湖南和浙江两地稻田土壤、稻田水和水稻植株中的消解动态。结果表明:溴虫腈在水稻土壤、稻田水和水稻植株中的平均添加回收率分别为90.0%~108.0%、96.2%~105.0%和87.9%~105.0%;溴虫腈在稻田环境中的消解动态符合一级动力学指数模型,在两试验地稻田土壤中的平均半衰期为11.17 d;稻田水中的平均半衰期为5.17 d;水稻植株中的平均半衰期为6.27 d。

| Abstract: | A field experiment and gas chromatography analysis were conducted for revealing the degradation dynamics of chlorfenapyr in paddy soil,paddy water and rice plant from Hunan Province and Zhejiang Province,respectively.The results showed that the average recoveries of chlorfenapyr residues in paddy soil,paddy water and rice plant were 90.0%~108.0%,96.2%~105.0% and 87.9%~105.0%,respectively;degradation dynamics of chromatography in paddy-field accord with first-order dynamic equations.The average half-life of chlorfenapyr in paddy soil,paddy water and rice plant from both province all was 11.17 d,5.17 d and 6.27 d,respectively. |
