土壤中绿磺隆残留量生物测定方法

Bioassay of Chlorsulfuron residues in soil.

用生物测定方法测定了土壤中绿磺隆残留量，建立了绿磺隆浓度（Ｙ）与玉米根长（Ｘ）之间的相关模式：Ｙ＝３０．５６２－３６．３８ＩｎＸ＋１４．８２８（ＩｎＸ）￣２＋２．０４３（ＩｎＸ）￣３．此模式适用于土壤中０．１～４．０μｇ／ｋｇ浓度范围的绿磺隆残留量测定，最低检出量为０．１μｇ／ｋｇ。

The soil Chorsulfuron residue bioassaymethod is described in the article. The relative model has beenestablished between the chlorsulfuron concentration(Y)andthe Iength of corn root(X):Y=30.562-36.38 InX+14.828(InX)￣2+2.043(Inx)￣3. The models is suited to determine thesoil Chorsulfuron residue concentration from 0.1 to 4.0 μg/kg. The minimum detection for Chlorsulfuron is 0.1μg/kg.
