摘要:

在模拟的土壤生态系统中研究了甲氰菊酯对蔬菜土中微生物数量的影响。结果表明:低浓度甲氰菊酯对蔬菜土中微生物数量影响不大,高浓度甲氰菊酯短期内,对土壤微生物具有抑制作用,17 d后恢复至对照水平。土壤微生物30 d对土壤中120mg/kg的甲氰菊酯的降解率为37.71%。

Abstract:

The effects of fenpropathrin on vegetable soil microbial population was investigated in a microcosm mimicking soil ecosystem. The results showed that the microbial population was slightly inhibited by fenpropathrin at low concentration, but significantly at high concentration. The vegetable soil microorganism could degrade 120 mg/kg fenpropathrin up to 37.71% in 30 d.
