- 摘要:
- NY5252012《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:NY5252012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%。
- Abstract:
- Calibration factor set for 1.5 lead the detection of organic matter oxidation increased by “NY5252012” 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 NY5252012 in the determination of organic matter oxidation correction factor for 1.5 was 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%.
