中文摘要：

NY525-2012《有机肥料》标准中有机肥有机质测定氧化校正系数为1.5,该设定导致检测时一些有机肥有机质的含量增大,有的甚至超过了100%。为使有机肥料现行标准中有机质氧化校正系数更加细化、精确化,选取有代表性原料样品进行测试。结果表明：NY525-2012中有机质测定氧化校正系数定为1.5较为笼统,按照基本资源氧化校正系数在1.32%~1.51%,派生资源氧化校正系数在1.30%~1.45%,可利用资源氧化校正系数在1.35%~1.47%。

英文摘要：

Calibration factor set for 1.5lead the detection of organic matter oxidation increased by ＂NY525-2012＂standard,some even more than 100%.In order to make the organic fertilizer standards more detail and accurate correction,and the organic matter of raw materials of representative samples were tested.The results showed that NY525-2012 in the determination of organic matter oxidation correction factor for 1.5was more general,in accordance with the basic resources was in 1.32%~1.51%for basic oxidation correction,oxidative correction coefficient for derived resources was in 1.30%~1.45%,the oxidative correction coefficient of available resources was in 1.35%~1.47%.
