为了评价4种水稻田新除草剂对后茬烟草的安全性,通过室内盆栽和田间小区试验评估了4种水稻田新除草剂对烟草生长的影响,并采用QuEChERS前处理方法结合高效液相色谱-串联三重四极杆质谱(HPLC-MS/MS)联用技术检测了...展开更多 为了评价4种水稻田新除草剂对后茬烟草的安全性,通过室内盆栽和田间小区试验评估了4种水稻田新除草剂对烟草生长的影响,并采用QuEChERS前处理方法结合高效液相色谱-串联三重四极杆质谱(HPLC-MS/MS)联用技术检测了二氯喹啉草酮在烟田土壤中的残留水平。结果表明,氯氟吡啶酯、氟酮·呋喃酮和硝磺草酮对烟草生长没有明显影响。在750~2 250 g a.i./hm2剂量下,二氯喹啉草酮对盆...
