- 摘要:
- 为了制定氯嘧磺隆在大豆上的安全使用标准，将50%氯嘧磺隆可湿性粉剂于大豆生长期进行茎叶喷雾处理，用高效液相色谱法，研究了氯嘧磺隆在大豆植株及土壤中的残留动态，测定了氯嘧磺隆在大豆及土壤中的残留量。两年的试验结果表明，氯嘧磺隆在大豆植株中比在土壤中消解得快，其半衰期分别8.7~8.6 h和10.7~11.7 d。大豆收获期籽粒中最终残留量低于0.05 mg/kg，土壤中最终残留量低于0.03 mg/kg。
- Abstract:
- In order to set up a standard procedure for safe use of Chlorimuron-ethyl in soil and soybean plants，a field experiment was conducted in 2004 and 2005 year and the residual dynamic of Chlorimuron-ethyl in soybean and soil were analyzed by HPLC.he results showed that Chlorimuron-ethyl decomposed fastly in both soybean plants and soil.ts half-lives in soybean plants and soil were 8.7-8.6 hour and 10.7-11.7 day,respectively.he final residues of the Chlorimuron-ethyl in soybean and soil were﹤0.05 and ﹤0.03 mg/kg respectively.
