摘要
测土配方施肥标准化验室进行内部质量控制是保证土壤分析数据质量的重要手段。笔者结合土壤分析围绕实验准备、实施、核查3个阶段中各个重要环节的质量控制进行讨论,列举了在检测环境、仪器设备、试剂器皿、样品制备、方法选择等方面进行质量控制的方法和注意事项,同时列举了标准物质法、质量控制图、标准曲线等多种方法在土壤分析质量控制中的运用。
Internal quality control is an important mean for standard laboralory, of soil testing and formulated fertilization to guarantee the testing quality of soil analysis. Based on soil analysis, various important parts of quality control were discussed through the three stages of experiment preparation, implementation and inspection. Methods and details on quality control were listed in the aspects of test environment, instrument, reagent, chemical vessels, sample preparation and method selection, etc. Practical applications of QC methods such as reference material, quality control charl, standards curve were also listed for aetual soil analysis.
