Inductively coupled plasma mass spectroscopy (ICP-MS) determination of the trace element of Physalis alkekengi L. and its influence on the succession cropping obstacle

摘要

To determine the contents of trace element (Mg, K, Ca, V, Mn, Fe, Co, Ni, Cu, Zn, Se, Pb) inPhysalis alkekengiL. rhizomes and the soil near the rhizomes, ICP-MS method was applied. The result indicated that the enrichment of Mg, K, Ca reduced, simultaneously, Se and Pb increased in the rhizomes along with the years increasing, suggesting the contents of Mg, K, Ca, Se and Pb are the important reason leading to the succession cropping obstacle ofP. alkekengiL.
