摘要:

摘要：本文以行业标准LY/T 1237-1999《森林土壤有机质的测定及碳氮比的计算》为基础，应用外加热重铬酸钾氧化-容量法测定森林土壤有机质含量，对测定结果的主要影响因素进行分析探讨，提出解决方案，以保障样品分析测试的准确度，提高工作效率。

Abstract:

Abstracts:Based on the standard LY/T 1237-1999 (determination of organic matter in forest soil and calculation of carbon nitrogen ratio), this paper determined the organic matter contents by the method of potassium dichromate heating oxidation volumetric. We analyzed and discussed the main influence factors on determining result. Furthermore, some solutions were proposed to guarantee the testing analysis accuracy on forest soil sample and enhance the test efficiency.
