浅谈土壤检测项目结果计算

Discussion the result calculation of testing items in soil analysis

建立一种统一的、更具可比性的土壤分析检测结果的计算方法。通过分析比较土壤检测现行有效的国家标准和行业标准,发现各标准中的结果计算差异主要在土壤水分概念以及数据的运用,提出统一以烘干土壤为基准并用干物质含量对称样质量进行修正的计算方法,这是一种更合理的结果计算方法。统一土壤检测项目结果计算方法更能体现检测结果的准确性和可比性,消除各检测项目分析过程中土壤水分的差异,简化实验过程,提高批量多项目检测的效率。

The differences between calculating results of the national and industry standards on soil testing were mainly from the different understanding on soil moisture. In this paper, a more reasonable calculating method using the dry soil as the benchmark was proposed. And the sample weight was corrected by the dry matter contents. The experimental process was simplified and the efficiency of batch multiitem testing was improved.
