| 摘 要： | 采用GC ECD测定了二甲戊灵在马铃薯及土壤上的残留动态和最终残留量。2年2地的测定结果表明:喷施33%(质量分数)二甲戊灵乳油(2 475 0 g·hm-2,有效成分),土壤中原始沉积量长春为2 98~11 22 mg·kg-1,济南为2 12~6 96 mg·kg-1;用方程Ct=C0 t -k计算半衰期,长春1 6~3 0 d,济南1 8~3 4 d。收获的马铃薯块茎上残留量低于推荐的最大允许残留限量值(0 1 mg·kg-1)。

| Abstract: | The dynamic residues and final residues of pendimethalin in potato tubers, plants and soil were determined with GC-ECD. A method for pretreatment and analysis of samples was established. The potato was applied with 33wt% EC pendimethalin (2 475.0 g ·hm -2, a.i.) and the results in 2002～2003 showed that the primitive residual amount in soil was 2.98～11.22 mg·kg -1 in Changchun and 2.12～6.96 mg·kg -1 in Ji’nan, and that half-life of pendimethalin in Changchun was 1.6～3.0 d and in Ji’nan 1.8～3.4 d. The final pendimethalin residues in potato tubers were lower than 0.001~0.006 mg·kg -1. |
