| 摘 要： | 研究了硝磺草酮在玉米植株、籽粒和土壤中的残留分析方法及残留动态。结果表明,硝磺草酮最小检出量为0.3ng,在植株、籽粒及土壤中的最低检测浓度分别为0.02mg/kg、0.01mg/kg和0.01mg/kg。硝磺草酮在植株中添加回收率为80.94%～89.0%,相对标准偏差为3.66%～12.54%;籽粒中添加回收率为78.11%～87.15%,相对标准偏差为3.95%～11.54%;土壤中添加回收率为81.27%～95.38%,相对标准偏差为4.25%～6.28%。植株中半衰期为5.6～6.8d,土壤中半衰期为10.4～10.8d。

| Abstract: | The method to detect mesotrione residue and the residual dynamics of mesotrione in maize plants,maize seeds and the soil was studied.The results showed that the minimum detectable amount of mesotrione was 0.3 ng.The minimum detectable concentrations of mesotrione in maize plants,maize seeds and the soil were 0.02 mg/kg,0.01 mg/kg and 0.01 mg/kg,respectively.The fortified recoveries of mesotrione in maize plants,maize seeds and the soil were 80.94%-89.0%,78.11%-87.15% and 81.27%-95.38%,with the relatively st... |
