摘　　要：As the main environmental factor of ginseng growth,illumination plays an important role in ginseng（ Panax ginseng） growth and development. Although ginseng is a shade-demanding plant,we need to get higher yield and quality under ideal light conditions. Three different illumination conditions for growth were created through different shading treatments. It was concluded that the adjustment of illumination according to monthly irradiance is beneficial to ginseng growth; appropriate illumination significantly affected root diameter; and SPAD value could also be used in the production of ginseng,but different light environments have influences on its accuracy. Reasonable light adjustment could improve the accuracy of the prediction value of SPAD.As the main environmental factor of ginseng growth,illumination plays an important role in ginseng（ Panax ginseng） growth and development.
