摘要
本研究选取泰山王母池、罗汉崖、中天门、南天门、花口顶5个不同海拔高度,长势相近古树(侧柏)下土壤为研究对象,测定土壤中N、P、K及微量元素(Ca、Mg、Cu、Zn)含量及pH。选取泰山王母池、罗汉崖、中天门、南天门、花口顶5个不同海拔高度,长势相近古树(侧柏)下土壤为研究对象,测定土壤中N、P、K及微量元素(Ca、Mg、Cu、Zn)含量及pH。结果显示:泰山随着海拔高度的增加,土壤pH逐渐降低,海拔165m以上,土壤中全氮含量随着海拔高度的升高先升高后降低;土壤全磷含量则是低海拔处最高达到25mg/kg,海拔300m左右为最低值;土壤含K量为先降低再升高的"U型"曲线,升高降低趋势明显,海拔847m左右为最低值;土壤含Ca量差异不显著,随着海拔高度的升高有下降的趋势,总体含量在700～800mg/kg;而土壤中Mg的含量则随着海拔的升高明显升高,各个海拔高度差异性显著;土壤中Cu的含量则呈现先下降后上升又下降的趋势,低海拔高度165m时,土壤含Cu量最高,高海拔1540m时最低;土壤中Zn的含量各个海拔高度差异显著,没有明显的变化趋势,300m处含量在1mg/kg以下。
This study used the soil under the old Platycladus orientalis （Linn.） lived similarly in Wang Muchi, Luo Hanya, Zhong Tianmen, Nan Tianmen and Hua Kouding from different altitude. To determine the content of available nitrogen （AN）, total phosphorus （TP）, available phosphorus （AP） and any other micro-amounts such as Ca, Mg, Cu, Zn, and pH. The results showed that with altitude ascending on Mountain Tai , the pH decreased. The N content of different altitude first increased then decreased; The content of total phosphorus in soil decreased down to 25mg/kg. At an altitude of 300 Where was the lowest. The content of K increased firstly then decreased in the obviously ＂U＂ curve. It was the lowest at 847m. The content of Ca was not significantly, range from 700-800mg/kg; The content of Mg increased significantly with the increasing of altitude. The content of Cu increased firstly then decreased. It was the highest at 165m and lowest at 1540m; The content of Zn had significant difference in different places, which get down to 1mg/kg at 300m.
