系统地研究了稻田土壤有机质氧化稳定性与土壤养分、土壤结构及水稻产量的关系。结果表明：土壤易氧化有机质含量与土壤有机质、全氮、碱解氮、土壤速效磷、速效钾、土壤阳离子代换量、土壤容重、孔隙度、土壤有机无机复合量等皆有显著的相关性，土壤有机质氧化稳定系数ＫＯＳ值与氮素矿化率呈显著负相关。且易氧化有机质含量与阳离子代换量、土壤有效养分指标及水稻产量的相关系数皆大于有机质总量与它们的相关系数。初步认为：土壤易氧化有机质含量和有机质氧化稳定系数，反映了土壤有机质品质，可作为衡量稻田土壤肥力及培肥水平的重要指标
The relationship between soil organic matter oxidation stability and soil nutrients, soil structure and rice yield was systematically studied. The results showed that there was a significant correlation between soil organic matter content and soil organic matter, total nitrogen, available nitrogen, soil available phosphorus, available potassium, cation exchange capacity, soil bulk density, porosity, soil organic and inorganic compound content , Soil organic matter oxidation stability coefficient KOS value and nitrogen mineralization rate was significantly negatively correlated. Moreover, the correlation coefficient between the content of organic matter and cation exchange capacity, soil available nutrient index and rice yield were all larger than the total organic matter and their correlation coefficient. It is preliminarily believed that the content of soil organic matter and the oxidation stability of organic matter reflect the quality of soil organic matter, which can be used as an important index to measure soil fertility and fertilization level in paddy field
