摘　　要：通过对感病及对照参Fe、Mn含量及发病条件的比较研究,认为人参红皮病是在白浆土的白浆化过程中,在周期性过湿的氧化还原状态波动的影响下,土壤中铁、锰向根部沉淀的结果。防治的重点,应是排水通气。提出了参床排水的设计方案。By comparitive study on Fe and Mn content of ginseng roots and the enviroments betweer healthy and infected plants. It was concluded that the red skin disease of ginseng was caused by pre cipitation of Fe and Mn on roots in the process of soil lessivation under the influence of fluctuation of redox in periodically over-wet condition of lessive soil. The main point of prevention should be to drain and aerate the over-wetted soil. A scheme for draining ginseng growing-bed soil was proposed.
