摘　　要：本文介绍了影响烯草酮降解的一些因素。明确了微生物、腐殖酸和单线态氧对土壤中烯草酮有降解影响，即施药后72h烯草酮在微生物、腐殖酸和单线态氧作用下，相对降解率分别为对％、52．61％和18．15％。而水溶液中的烯草酮在光和腐殖酸的作用下，不产生降解。The degradation factors of clethodim were introduced. The results showed that microorganism. humic acid and singlet state oxygen in soil fluenced degradation of clethodim. After clethodim was used for 72 hours, in a condition of microorganism, humic acid and siglet state oxygen, the relatively degradation rate of clethodim in soil respectively were 31 %, 52. 6% and 18.15%. However in a condition of light and humic acid, clethodim wasn' t occured degradation in aqueous solution.
