土壤养分检测能力验证结果分析

Evaluation on Analytical Results of Soil Nutrient in Proficiency Testing Program

为了提高四川省农业检测实验室土壤养分的检测能力,组织了土壤pH、有机质、全氮、有效磷、碱解氮、缓效钾和速效钾等7个项目的能力验证活动。采用稳健统计对结果进行了分析和评价,参加实验室的7项能力验证结果满意率为71.1%~100.0%,客观反映参加实验室的测试能力和测试水平。根据参加实验室反馈的原始记录和评定结果,给出了针对性的技术分析和建议。

The proficiency testing activities of pH,organic matter,total nitrogen,available phosphorus,alkali-hydrolyzed nitrogen,slow-acting potassium and quick-acting potassium in soil were organized to improve the soil nutrient detection ability of Sichuan Agricultural testing laboratory.The results were analyzed and evaluated by robust statistcs,and the satisfaction ratios of the participatory labs were 71.1%~100.00%,which objectively reflected the test ability and test level of the laboratory.The technical analysis and recommendations were provided according to the original recording and ability evaluation results.
