| 摘 要： | 以不同地区的红松为研究对象,测定了针叶中Ca2+、Mg2+、S及土壤中交换性Ca2+、Mg2+、有效S的质量分数,并结合海拔、纬度、坡度等地形因子进行相关性分析。研究结果表明:红松针叶营养中Ca2+质量分数最大,Mg2+和S的质量分数相差不大;红松林下土壤中交换性Ca2+、Mg2+、有效S的质量分数比较高,并不需要施肥,质量分数由大到小顺序为Ca2+、Mg2+、S。土壤交换性Ca2+质量分数与针叶Ca2+质量分数不相关,土壤交换性Mg2+质量分数与针叶Mg2+质量分数极显著正相关,土壤有效S质量分数与针叶S质量分数不相关。针叶中的Mg2+与纬度极显著正相关,与海拔极显著负相关;Ca2+与坡度极显著正相关;S与坡度显著正相关。

| Abstract: | An experiment was conducted to select different places Pinus koraiensis in the latitude to analyze the leaf and soil Ca2+, Mg2+, S element determination.Combining with the relevant analysis of their elevation, latitude and slope, the con-tent of Ca2+in leaf was the highest, Mg2+in leaf was similar with S in leaf.Comparison of the size of the soil nutrient con-tent was Ca2+﹥Mg2+﹥S.The contents of Ca2+, Mg2+, S were rich without fertilization.Ca2+content in soil and in leaf had no significant correlation.Mg2+in soil and in leaf showed a highly significant correlation.S in leaf and in soil had no significant correlation.Mg2+in leaf was remarkably related with latitude, and had the remarkable negative correlation with elevation.Ca2+and S in leaf was remarkably related with slope. |
