三唑醇及其对映异构体在3种不同类型土壤中的降解动态
Degradation dynamics of triadimenol and its enantiomers in three different types of soil
摘要
Abstract
The degradation dynamics of triadimenol and its enantiomers in fluvo-aquic soil ( organic substances content is 1. 90%, pH 6. 85)from Hangzhou city in Zhejiang Province, paddy soil(organic substances content is 1. 63%, pH 4. 94 ) from Jinhua city and red soil ( organic substances content is 0. 38%, pH 4. 03) from Lanxi city under laboratory conditions were investigated. The results showed that half-lives of triadimenol were 56. 4, 105. 0 and 154. 0 days in fluvo-aquic soil, paddy soil and red soil, respectively. The degradation rate of triadimenol at 180 days were 91. 9%,79. 2% and 57. 7%, respectively. Triadimenol-A transformed to triadimenol-B twice and triadimenol-B transformed to triadimenol-A once in fluvo-aquic soil. Triadimenol-A transformed to triadimenol-B once and triadimenol-B transformed to triadimenol-A once in paddy soil and red soil. In conclusion, triadimenol enantiomers′degradation dynamics varied in different soils.关键词
