Abstract—with the trend of global economic integration, agriculture, forestry, chemical and other fields. A rapid
strengthening economic and trade exchanges between different method was established for simultaneous determination of Cu,
countries, the economic value of products of designations of Pb, Zn, Cr, Cd, Ni, Mn, Sr and other 14 kinds of elements in
origin increased. Fourteen trace elements of soil and plants KGL and soil by ICP-AES with wet digestion, in order to find
samples were determined by ICP-AES. The accuracy of method the fingerprinting marker of products of designations of origin.
