巢湖马鞍山土壤有机质和N、P变化研究

Study on Soil Organic Matter and N and P Variations of Ma'anshan in Chaohu

对巢湖马鞍山从山脚到山顶进行不同海拔土壤取样,经过相关处理和分析表明:在空间上,随着海拔的升高,土壤有机质、水解N、全N、全P的含量都基本呈减少的趋势,而速效P含量则呈现出山体下部与顶部含量高、中部含量低的特点;在时间上,有机质、全N、水解N含量基本表现为1月份小于4月份,而全P的含量呈现出4月份比1月份减少的趋势。

It takes soil samples at different elevations from the foot to the top of the hill of Ma'anshan in Chaohu.It shows after correlated processing and analysis that on point of space,the content of soil organic matter,hydrolysis N,total N and total P are getting less along with the increase of elevation and the content of quick result P is higher at the lower and top hill and lower at the middle and;on point of time,the content of soil organic matter,total N and hydrolysis N becomes lower in January than that of in April and the content of total P becomes lower in April than that of in January.
