【摘要】 以38份不同生态类型的黄瓜品种(系)为试验材料进行研究,在黄瓜盛果期进行毒死蜱农药喷施处理,利用气相色谱对黄瓜果实进行检测,以期对黄瓜主要种质资源毒死蜱的残留性进行评价。结果表明,不同供试材料果实中的毒死蜱残留量有较大差异,毒死蜱残留量平均值为0.795mg·kg-1,变幅为0.072～1.835mg·kg-1,变异系数为0.549。不同生态类型和来源地的黄瓜种质果实中毒死蜱的残留量有明显差异。筛选出果实中毒死蜱残留量符合国家标准0.1mg·kg-1(GB2763—2005)的有1份材料。更多还原

【Abstract】 In this experiment,38 cucumber(Cucumis sativus L.)samples of different ecological types were tested.The chlorpyrifos pesticide was sprayed on cucumber samples during the full fruit period.Then we tested the samples with gas chromatography,in order to evaluate the chlorpyrifos residue in the main cucumber germplasm resources.The results showed that there were great differences between different samples fruits in the level of chlorpyrifos residue. The chlorpyrifos residue is 0.795 mg·kg -1 on average,the change is between 0.072-1.835 mg·kg -1 ,and the CV is 0.549. Furthermore,different chlorpyrifos residue levels exists in cucumbers fruits of different ecological types and cucumbers from different producing areas. Only one sample,with chlorpyrifos residue lower than the national standard 0.1 mg·kg -1 (GB2763—2005),was selected.更多还原
