摘　　要：研究了花卉常用的 4种栽培基质 (草炭土、植金石、仙土和含 2 0 %河砂的腐殖土 )对59Fe的吸附及解吸附。结果发现 ,植金石和腐殖土对59Fe吸附最高 ,且土柱上层高于下层 ,其解吸附较少 ,这与土壤的pH值有关 。The adsorption\|desorption of 59 Fe in 4 types of soils for flower planting were studied.The results indicated that the adsorption of 59 Fe in Zhijingshi soil and muck soil is high,and upper layer is higher than lower layer.The desorption is small and relates to pH.
