摘　　要：为探明烯酰吗啉在不同土壤中的降解状况,采用LC-MS/MS检测方法,对烯酰吗啉在不同土壤中的降解进行测定。结果表明：烯酰吗啉在土壤中的添加回收率为85.55%~99.52%,相对标准偏差（RSD）为0.58%~1.75%,土壤中含水率越多,微生物越多,有机质越多,烯酰吗啉在土壤中的降解越快。烯酰吗啉在土壤中的降解主要受微生物和有机质含量影响。In order to explore the degradation factors of dimethomorph in different soils,a method of determining dimethomorph in soil was developed by LC-MS/MS.The results showed the adding recovery rate of dimethomorph in the soil was 85.55% ~99.52%,the relative standard deviation（RSD）was0.58%~1.75%,the more the moisture content,microorganism,and organic matter in soil,the faster the degradation of dimethomorph in the soil.The speed of dimethomorph＇s degradation in soil was mainly influenced by microorganism and organic matter content in soil.
