摘　　要：采用田间试验方法,对5%顺式氰戊菊酯微乳剂在大棚、露地条件下甘蓝及土壤中残留动态进行了对比研究。结果表明,顺式氰戊菊酯在大棚甘蓝中降解动态方程为Ct=0.1005e-0.1023t,露地为Ct=0.1417e-0.1764t,半衰期分别为6.8d和4.2d。顺式氰戊菊酯在大棚土壤中降解动态方程为Ct=0.07326e-0.0703t,露地为Ct=0.0959e-0.073t,半衰期分别为9.8d和5.7d。顺式氰戊菊酯在大棚上的降解速度要稍慢于露地。The residual dynamics of esfenvalerate on cabbage and soil in plastic house and open field were compared.After application,the dynamics of esfenvalerate residues on cabbage grown in plastic house and field could be described, respectively,as Ct=0.1005e^-0.1023t,Ct=0.1417e^-0.1764t;with a half-life of 6.8 and 4.2 days,respectively. The dynamics of esfenvalerate residues in soil in plastic house and field could be described, respectively, as Ct=0.07326e^-0.0703t, Ct=0.0959e^-0.073t, and respectively with a half-life of 9.8 and 5.7 days. The degradation of esfenvalerate on cabbage grown in the plastic house was slower than that of cabbage grown in open field.
