摘　　要：为评价腐霉利在保护地番茄上使用的安全性,建立其使用规范,2013年在6地进行了15%腐霉利烟剂在番茄和土壤中的残留试验。样品采用乙腈提取,固相萃取柱净化,气相色谱电子捕获检测器进行检测,外标法定量。结果表明：腐霉利在番茄和土壤中的半衰期分别为1.9～3.7 d和1.4～2.7 d。番茄及土壤中腐霉利残留量均低于2 mg/kg。In order to evaluate the safety and establish the regular use of procymidone in tomato in protected field, the final residue and degradation dynamic of procymidone 15%FU were studied in six provinces in 2013. The samples were extracted with acetonitrile, cleaned up by SPE column, and determined using GC with ECD. The results showed that the half-lives of procymidone in tomato and soil were 1.9-3.7 d and 1.4-2.7 d. The residues were all below 2 mg/kg.
