摘　　要：农药能够有效防治茶园中病虫草害及调节茶树生长,而茶园土壤是农药的“储存”和“分配”中心。无论直接施用于茶树,还是施用于茶园杂草,农药最终都会到达土壤,随后被茶树吸收,造成茶叶中农药的残留污染。因此,分析茶园土壤中农药的残留情况才能从根本上探究茶叶中农药的污染问题。文章综述了近年来茶园土壤中多种农药的提取、净化和检测方法,对比了土壤中不同农药检测方法的优缺点,发现QuEChERS结合超高效液相色谱-串联质谱法已成为土壤样品中农药多残留定性定量分析最可靠的检测方法,该方法为保障我国茶园土壤生态健康及茶叶质量安全提供技术支撑。Pesticides can effectively control diseases and insects in tea gardens and regulate the growth of tea plants,and the soil of tea gardens is the"storage"and"distribution"center of pesticides.Whether applied directly to the tea plants or to the weeds in tea gardens,pesticides eventually reach the soil and are subsequently absorbed by the tea plants,resulting in the contamination of residual pesticides in the tea.Therefore,the analysis of pesticide residues in tea garden soil can fundamentally explore the pesticide pollution in tea.In this paper,the extraction,purification and detection methods of various pesticides in soil in recent years were reviewed.By comparing the advantages and disadvantages of different soil pesticide detection methods,we found that QuEChERS combined with UPLC-MS/MS has become the most reliable detection method for qualitative and quantitative analysis of pesticide residues in soil samples,which provided technical support for ensuring the ecological health of tea garden soil and the quality and safety of tea.
