The characteristic elements analysis of litchi in the main production areas, Guangdong province

By comparative analysis of characteristc distribution, correlation, biological absorption coefficient and the characteristc element pairs of 13 trace elements in Litchi and soils from four production areas, Guangdong province, the results revealed that the characteristic elements of four production areas are Cu, Mg, Zn, Fe, Cr, and the characteristic element pairs are Cu-Li, Cu-Zn, Li-Mg, Li-V, Mg-V, Mn-Ti, Pb-V. The group of Cu, Zn, Cu-Zn pairs was considered as the characteristic significance, which provided a clue in further research on geological breakground of geographical origin products.
