【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8.77～8.86 h和10.47～11.07 d。大豆收获期籽粒中最终残留量低于0.005mg/kg,土壤中最终残留量低于0.003 mg/kg。更多还原

【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.The results showed that Chlorimuron-ethyl decomposed fastly in both soybean plants and soil.Its half-lives in soybean plants and soil were 8.77-8.86 hour and 10.47-11.07 day,respectively.The final residues of the Chlorimuron-ethyl in soybean and soil were﹤0.005 and ﹤0.003 mg/kg respectively.更多还原
