摘  要:
以科尔沁大青沟差巴嘎蒿群落的土壤为研究对象,采用挖掘法对土壤做剖面,研究了不同深度下土壤有机碳含量与土壤养分(氮、磷、钾)的分布及其相互关系。结果表明:1)在土壤深度0~60cm内,随土壤深度的增加,土壤有机碳含量整体呈下降趋势,其变化范围18.31~5.18g/kg,在0~5cm内,达到最大值为18.31g/kg;2)对土壤养分分析得知,速效钾平均含量为101.29g/kg,有效磷平均含量为2.89g/kg,碱解氮平均含量为18.77g/kg,全钾平均含量(33.60g/kg)比全磷平均含量(0.09g/kg)、全氮平均含量(0.69g/kg)都大;3)通过相关分析可知,土壤有机碳含量与速效钾含量存在极显著的相关性,土壤有机碳含量与全效钾含量不相关。

摘  要:
Through the research of the soil profile,the study on distribution and relationships of soil organic carbon and soil nutrient(Nitrogen,Phosphorus,Potassium)under different depth in the Artemisia halodendron community in Daqinggou of Horqin was conducted.The results were as follows:1) in 0~60 cm depth soil,the soil organic content decreases with depth,which changes in scope of 18.31~5.18g/kg,the maximum of them is 18.31g/kg in 0~5cm depth soil;2) Through soil nutrient analysis,average content of available potassium,available phosphorus and available nitrogen were 101.29g/kg,2.89g/kg,and 18.77g/kgrespectively.Total content of potassium,phosphorus and nitrogen were 33.60g/kg,0.09g/kg and 0.69g/kg;3) The correlation analysis shows that soil organic carbon and available potassium content have a significant correlation but no correlation with soil organic and the total potassium.
