土壤有机质是土壤养分的源泉,尤其是土壤中氮素等营养元素的主要来源。因此,土壤有机质必然与全氮,碱解氮间存在着相应的内在联系,探讨这种内在关系,并对其进行相应的统计分析,以相应的数学模式来表示土壤养分间变化的规律性,对以某一种养分含量测试数据估算另种养分含量,或验证另种养分含量测试结果的准确性及可靠性有重要意义。 Soil organic matter is the source of soil nutrients, especially the main source of nitrogen and other nutrients in the soil. Therefore, the relationship between soil organic matter and all-nitrogen and alkali-nitrogen is bound to be discussed. The inner relationship is discussed and the corresponding statistical analysis is made. The regularity of soil nutrient change is expressed by the corresponding mathematical model, It is important to evaluate the nutrient content of another nutrient content test data or to verify the accuracy and reliability of the test results of other nutrient content.
