土壤有机质含量与土壤物理性能参数的相关性分析

Analysis of Interrelation Between Organic Matter Content and Soil Physical Property Parameters

根据大田土壤物理特性参数测定的试验数据,分析了土壤有机质含量与土壤含水量、物理性粘粒含量、土壤入渗能力之间的相关关系。分析结果表明:土壤有机质含量与这些土壤物理参数有一定的相关性,且拟合曲线符合对数关系。研究结果对土壤保肥和农业增产具有重要意义。

The interrelations between the organic matter content and water content, physical clay content and infiltration capacity into soils are analyzed by the field experimental data of the physical property parameters of soils. The results of the research show that there is a certain interrelation between the organic matter content and the soil physical property parameters. The correlation curve accords with the logarithmic interrelation. The results are of great significance for the retaining of soil fertility and the increasing of farming production.
