摘要
[目的]掌握蔬菜中农药残留检出率的规律性,为提高西宁市蔬菜质量安全提供参考。[方法]2011-2013年在西宁市规模化蔬菜生产基地和农贸市场共采集蔬菜样品784个,采用气相色谱法对其进行农药残留检测。[结果]西宁市蔬菜农药残留检出率具有一定的规律性,1和3月是农药检出的高峰期,其中豆类、甘蓝类和根菜类是农药残留检出率较高的蔬菜种类。农药残留主要集中在三唑酮、甲拌磷、氧化乐果;其次为乙酰甲胺磷、毒死蜱、腐霉利。[结论]为蔬菜生产过程中农药残留的控制提供了理论依据。
[Objective] To master the regularity of detection rate of pesticide residue in vegetables,and provide reference for improving quality and safety of vegetables in Xining City. [Method]From 2011 to 2013,wholesale market,farmers market and vegetable production base,collect the total samples of vegetables 784 were determined by gas chromatography GC. [Result]Vegetable pesticide residue detection rate in Xining has certain regularity. January and March is at the peak of pesticide detection and pesticide residue detection rate higher species including legume vegetables,Brassica vegetable and root vegetable. The main residue pesticides are Traidimefon,Phorate,Omethoate,and the next are Acephate,Chlorpyrifos,Procymidone. [Conclusion] The study can provide theoretical basis for control of pesticide residues in vegetable production.
