| 摘 要： | 为了制定糖草酯在大豆上的安全使用标准,采用田间试验方法,研究了糖草酯在大豆及土壤中的残留动态,应用HPLC测定了糖草酯在大豆及土壤中的残留量.两年的试验结果表明,糖草酯在土壤和植株中半衰期分别为1.8～2.4 d和0.63～0.69 d;在大豆植株中的消解速度要快于土壤;大豆收获期土壤和籽粒中的残留量均低于各自检出极限0.005 mg/kg和0.01 mg/kg.从吉林和黑龙江两个试验点的残留量测定结果看,糖草酯在土壤和大豆鲜植株中的消解较快,具有相似的消解规律.

| Abstract: | In order to make up a standard procedure for safe use of quizalofop-P-tefuryl on soil and bean,a field supervised conducted to reveal dynamic of quizalofop-P-tefuryl in soil and bean,respectively.The residue of quizalofop-P-tefuryl in soil and bean were determined by HPLC produre.The result of two year's study showed that half-life of quizalofop-P-tefuryl in soil and plant were 1.8-2.4 day and 0.63-0.69 day.degradation of quizalofop-P-tefuryl was relatively fast in plant.The final residues in soil and soybean were all below their detectable limits of 0.005 to 0.01 mg/kg. |
