摘　　要：建立气相色谱法测定猕猴桃和土壤中百菌清残留的方法,方法的检出限为0.005 mg·kg-1,通过对百菌清在猕猴桃和土壤中降解动态研究,表明百菌清在猕猴桃和土壤中的降解半衰期为5.74 d和7.76 d,施药后第35 d,猕猴桃中百菌清未检出,土壤中百菌清残留量为0.012 mg·kg-1,推荐百菌清在猕猴桃上使用的安全间隔期为35 d。The method was developed for the determination of chlorothalonil residues in Actinidia and soil using Gas Chromatography.The detection limit of chlorothalonil was 0.005 mg-kg-1 ,the half-life of 5.74 days and 7.76 days in the degradation of chlorothalonil in Actinidia and soil was indicated.After spraying 35 days,the chlorothalonil residues were not detected in Actinidia and the chlorothalonil residues in soil was 0.012 mg-kg-1 .The use of the safety interval of chlorothalonil on the Actinidia is recommaned as 35 days.
