【摘要】 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。更多还原

【Abstract】 In the work, the reason of ginseng red skin sickness in albic soil were studied by the ecological quadrat methods. Results showed that achve reducing organic substances could form in bed soil under moisture capacity and well aerated condihons, and theypromoted the activation of iron and manganese oxides and enhanced the accumulation of divalent iron and manganese. Ginseng red skin sickness could be attributed to the oxidizing and depositing of ferrous iron in epidermis of ginseng root or to the protechve reachon of ginseng root to poisonousnss of fermus ions. The results also showed that divalent manganese inhibited ginseng red skin sickness. In the bed soil, achve reducing substances is the induced factor and ferrous ions is the leading factor in the occurrence of ginseng red skin sickness.更多还原
