摘要
有机质是土壤检测的重要指标之一,也是衡量土壤肥力高低的重要指标。对重铬酸钾容量法中不同的加热方式进行了比较分析,对土壤有机质检测方法进行了改进,发现恒温电加热法可控性好,结果精确度高,检测结果与标准检测方法一致,可实现快速批量检测。
Organic matter is one of the important indexes of soil testing, and also an important index to measure soil fertility.The different heating methods in the potassium dichromate volumetric method were compared and analyzed, and the detection method of soil organic matter was improved. It is found that the constant temperature electric heating method is controllable, the result precision is high, the detection result is consistent with the standard testing method, and the fast batch inspection can be realized.
