山东青州市耕地利用方式对土壤养分状况影响研究

通过调查山东省青州市不同耕地利用方式间土壤养分数据,利用数理统计处理软件对土壤养分数据进行处理分析,对耕地利用方式与土壤养分状况之间的关系进行了系统探讨。结果表明,不同耕地利用方式对土壤中有机质、大量元素以及中量元素都有显著的影响。对有机质和大量元素的影响程度为碱解氮>有效磷>全氮>速效钾>缓效钾>有机质;对中量元素的影响程度为交换性钙>交换性镁>有效硅>有效硫;土壤中的微量元素除有效锌、硼在不同耕地利用方式间有差异性外,耕地利用方式的变化对有效锰、铜、铁以及氯离子均没有显著的影响。

Effects of Different Arable Land Use on Soil Nutrients in Qingzhou County of Shandong Province

This study was undertaken to evaluate the effects of arable land use on soil nutrients in Qingzhou county of Shandong province. This study used mathematical statistical software to deal with the basis data. The result indicated that different arable land use could exert an important influence on organic matter, macroelements and middle elements. The influence degrees were alkali hydrolysable N > available P > total N > quickly available K > slowly available K > organic matter and exchangeable Ca > exchangeable Mg > available Si > available S. Different arable land use only exerted an important influence on available Zn and B in microelements. The influence on available Mn, Cu, Fe and chloride ions were not very remarkable.
