Abstract
OBJECTIVE
To study the effect of inorganic fertilizer on the heavy metal and harmful element residues, the content of total ginsenoside and yield of ginseng.
METHODS
Graphite furnace atomic absorption spectrometry was used for determinating the content of lead, cadmium, copper, nickel and chrome atomic fluorescence spectrometry for arsenic, antimony and mercury. The content of ginsenoside Rg1, Re, Rb1 was determined by HPLC.
RESULTS
Compared with the blank ginseng, the ginseng in the normal fertilization did not significantly increase the content of heavy metals. The heavy metals and harmful elements of ginseng met the requirement of Chp 2010.
CONCLUSIONS
Appropriate fertilizer could help the growth of ginseng. Compared with the production, it should focus more on the content of total ginsenoside.
