对８个人参根际土壤研究结果表明，土壤ＦＡ／可提取总Ｃ比值与病情指数相关显著（ｒ＝０７２２ｎ＝８），ＦＡ高，使溶液中高铁还原并以有机络合铁的形态而被吸附于参根周表皮。红皮病发生与根际土壤ｐＨ上升有关。本文还研究了土壤中微量元素与人参红皮病的关系
The results of the study on eight ginseng rhizosphere soils showed that the total soil FA / total C extractable ratio was significantly correlated with the disease index (r = 0722n = 8) and FA was high. The form is adsorbed on the ginseng root epidermis. The occurrence of erythroderma is related to the increase of rhizosphere soil pH. The paper also studied the relationship between trace elements in soil and erythroderma ginseng
