[The influences of inorganic elements in soil on the geolism of Atractylodes lancea].
OBJECTIVE
To study the influence of inorganic elements in soil on the geolism of Atractylodes lancea.


METHODS
The concentrations of 15 kinds of inorganic elements of regional A. lancea and their correspondingly soils were determined, and the data were analysed with the SPSS10.0 software.


RESULTS
The mean concentration of Ni in geoherbs of A. lancea was 3 times higher than that in the non-geoherbs. The accumulation of Ca is high in geoberbs. There is no relationship between the concentrations of inorganic elements in A. lancea and those in their corresponding soil.


CONCLUSIONS
A. lancea adjusts the concentration of inorganic elements mainly by active absorption, and there are good relationship between the accumulation of Fe and Cr, Fe and Hg, Hg and Cr, As and Pb, Co and Sr.
