摘要:
研究首先基于GC-TOF/MS(气相色谱飞行时间质谱联用仪)对叶菜根系分泌物成分进行定性分析,然后选取单一根系分泌物成分如有机酸、氨基酸、糖类对土壤中结合态苯醚甲环唑和吡虫啉的活化规律进行研究。试验结果表明,基于GC-TOF/MS分析叶菜根系分泌物样品共检测出535个特征质谱峰,基于FiehnBinbase数据库共定性出的75个化合物,包括糖醇类20个、氨基酸类6个、有机酸类31个、脂肪酸类10个、其他类8个。不同根系分泌物对土壤中2种结合态农药的活化差异存在显著差异,其中对结合态苯醚甲环唑的活化效果为草酸>柠檬酸>丙氨酸>甘氨酸>葡萄糖>果糖,而对结合态吡虫啉的活化效果为柠檬酸>草酸>果糖>葡萄糖>甘氨酸>丙氨酸。另外,同一根系分泌物对结合态苯醚甲环唑的活化效果要高于吡虫啉,这可能与农药的物理化学性质相关,如辛醇比分配系数(lgKow)等。研究结果对农产品安全生产以及有效地评价土壤残留农药的危害风险具有重要的理论指导意义。
