本文采用生态样块的方法，对白浆土区人参红皮病发生条件做了较深入的研究。结果表明，在床上处于田间持水量且通气状况良好情况下，活性还原有机物质仍可形成，并促进土壤铁、锰氧化物活化，使亚铁、二价锰积累。人参红皮病是亚铁在参很周皮氧化沉积的结果，也可能是参根对亚铁毒害作用的保护性反应，而二价锰对红皮病有抑制作用。床土活性还原有机物质是红皮病发生的诱导因素，而亚铁则是主导因素。
In this paper, ecological samples of the method of white soil area ginseng erythroderma conditions made a more in-depth study. The results showed that active organic matter could still be formed when the bed was in the field with good water holding capacity and ventilation, and the iron and manganese oxides in soil could be activated and ferrous and manganese could be accumulated. Ginseng erythroderma is the result of the oxidative deposition of ferrous iron in the periforms of the peri-epidermis. It may also be a protective reaction of the root to the toxic effect of ferrous iron, while the bivalent manganese has an inhibitory effect on erythroderma. Active reduction of bed soil organic matter is an inducing factor for the occurrence of erythroderma, while ferrous iron is the dominant factor.
