摘　　要：[目的]研究海拔与生长时间对栽培人参土壤中大量元素的影响。[方法]采集我国人参主产地长白山地区不同人参生长时间、不同海拔的人参土壤,测量其大量元素和微量元素的含量,并研究变化规律。[结果]相同参龄条件下,土壤中大量元素pH值、有机质、全氮、全磷、全钾、碱解氮、速效磷和速效钾整体随着海拔高度的增加而变化,不同参龄土壤,大量元素含量整体随着参龄年限的增长而变化,其中土壤pH值随着参龄的增长有变小的趋势。[结论]不同海拔与生长时间对人参大量元素均有影响。[Objective] To study the impact of growth years and altitudes on the macro elements in ginseng-growing soils.[Method] The ginsengs with different growth years were collected from different altitudes of Changbai Mountain in China,and the contents and change laws of both macro and micro elements in the ginsengs were determined.[Result] The pH value,organic matter,TN,TP,TK,available nitrogen,available K and available K in the soil cultivated with the same ages of ginseng improved with the elevating altitude.The macro elements contents in the soil cultivated with the different ages of ginseng changed with the increasing years of growth,and soil pH showed a decreasing tendency with the extending years of growth.[Conclusion] Both altitude and growth years produce influence on the macro elements contents in ginseng-growing soils.
