丁草胺在蔬菜及环境中的残留探讨

Study on Butachlor Residues in Vegetables and Environment

摘要: 本文应用可行的丁草胺在蔬菜中残留分析方法,通过对除草剂丁草胺在蔬菜和土壤中残留检测,探讨其在环境中的残留性。根据丁草胺在蔬菜和土壤中的降解速率,表明丁草胺属低残留农药,残留积累现象不明显。建议以900g/hm2和1350g/hm2两种浓度使用较经济安全。

Abstract: The reliable method was used to analyse residues of herbicide butachlor in vegetables and soil.According to the degradative speed of butachlor in vegetables and soil,the result showed that butachlor belonged to the lower residue herbicide,and the residue accumulation was not distinct.It was suggested that the concentration for safe use was 900g/hm2 and 1350g/hm2.
