摘要： 采用砂滤管法和田间试验，结合室内分析，测定了７种有机物料的腐殖化系数、分解量以及土壤有机质矿化率。提出了中、低产田在各保持两个量级有机质平衡对，每年应投入各有机物料的数量。研究结果为河套灌区中、低产田的改土培肥，以及指导合理施肥提供了量化指标。

Abstract: Humification coefficients and decomposition ratio of 7 sorts of organic matter,mineralization ratio of soil organic matter have then tested.The tests were conducted through both field experiments by using the methods of sand filter tube and the analysis in the lab.Two grades of yearly input of organic fertilizer has been suggested for the organic matter balance of medium or low productive soil respectively.The studies provided the quantitative criterions for improving soil condition and proper fertilizer applications in medium and low productive soil.
Key words:
Soil organic matter balance,
Humification coefficient,
Minerallzation of soil organic matter
