有机肥料中有机质的测定及影响因素

Determination of organic matter in organic fertilizer and its influencing factors

目前有机肥料中有机质的检测方法最广泛的为重铬酸钾容量法,在此检测过程中的不当操作以及不同的影响因素会对检测结果造成误差。通过对样品制备情况,检测条件的优选,对反应温度和时间的准确控制,减小了误差。

At present,the most widely used method of detecting organic matter in organic fertilizers is potassium dichromate volumetric method. Improper operation in this detection process and different influence factors will cause errors in the test results. Through the preparation of samples,the optimization of detection conditions,the accurate control of reaction temperature and time,the existence of error is reduced.
