摘  要:
以抚顺地区的不同林龄的落叶松林为研究对象,通过采集林下土壤进行化学性质变化分析试验,结果表明:随着树龄的增长,林下土壤pH值逐渐增大,由偏酸性转变成偏碱性;有机质随着林龄的增长而增多,速效氮钾元素呈增多趋势,而速效磷呈递减趋势。

摘  要:
Taking different-aged larch in Fushun Region as research objects,experiments of analyzing chemical properties by collecting undergrowth soil were conducted.Result shows that PH value increases with the increase of forest age;the forest soil change from partial acid to alkaline.Organic matter increase with the increase of the forest age;available nitrogen & potassium show an increasing trend,while available phosphorus show a decreasing trend.
