    摘要对肥料中腐殖酸含量测定的不确定性因素进行了分析，并在现行国家标准或行业标准的基础上对腐殖酸含量检测方法进行了优化，以期为各种腐殖酸肥料标准的制定和检测提供参考。试验结果表明，优化后的方法既可以对成分复杂的腐殖酸类产品(如风化煤)进行测定，又可对腐殖酸钠及其他水溶肥料中腐殖酸含量进行测定。

    AbstractThe uncertainties in determination of humic acid content in fertilizers are analyzed, and based on current national standard and industrial standard, the determination method of humic acid content is optimized in order to provide a reference for formulating humic acid fertilizer standard and detection method. Experimental results show that the optimized method can not only determine humic acid products with complex compositions, but also can determine humic acid content in sodium humate and other water- soluble fertilizers.
