摘要
对有机肥料中有机质的测定,按现行标准NY525-2002分析耗时,试剂用量大,操作过程手续繁琐等。在多年的有机质分析工作中,对有机肥料中有机质含量测定,采用不同方法进行了实验比较,并从溶液配制、所用器皿、试剂用量等方面进行了深入研究。
For the determination organic matter in organic fertilizers , according to current standards NY525 -2002 analysis of time-consuming and reagent large, the process is complicated and so on. after years of analysis in organic matter, organic matter content of organic fertilizers measured using different methods for experiments, and from the solution preparation, the use of containers, reagent and other aspects of the in-depth study,improve and optimize potassium bichromate titrimetric method determination organic matter content in organic fertilizers.
