| 摘 要： | 报道了苄嘧磺隆在水稻上的残留量分析方法。样品经提取、液－液分配、Ｃ－１８小柱净化，添加浓度０．０１～２．００ｍｇ／ｋｇ，回收率可达到７３．５％～９６．３％。北京、杭州两地的试验结果表明：①残留消解半衰期，田水为３．０～３．５ｄ，植株为６．８～８．１ｄ，土壤为１７．６～２２．１ｄ。②３０％威农可湿性粉剂每６６６．７ｍ＾２有效量５．０～７．５ｇ施用，糙米、谷壳、土壤、植株中的残留量≤０．０３ｍｇ／ｋｇ。

| Abstract: | Residue determination of bensulfuron-methyl on rice was studied. Samples were extracted,liquid-liquid partitoned, and cleaned up through C-18 cartricdge. Fortified with 0.01 - 2.00 mg/kg, the recovery rates amounted to 73.5%-96.3% .Result of the two site experiments showed that: (1)Half life:3.0- 3.5 days in field water, 6.8-8.1 days in straw, 17.6-22.1 days in soil; (2) Applying 5.0 - 7.5 g bensulfuron-methyl every 666.7 m2,the final residue in rough rice,husk,soil,rice straw was all ≤0.03 mg/kg. |
