title: [Biological effects of supplements on soil properties and the growth of Panax quinquefolium].
abstract: This paper suggests that the physical and chemical characteristics of soil in American ginseng field were greatly improved after utilization of supplement on soil. Compared with the contrast, the soil gravity ratio decreased from 0.812 g/cm3 to 0.715 g/cm3, while the soil porosity increased from 69.36% to 73.03%. These improvements are benefit for the growth of Panax quinquefolium. Biological observations show that the fresh weight of ginseng root enhanced 53.8%, and the content of total saponins in root enhanced 0.5%-1% (get to 8.28%).
