对几种非腐解有机物料施于水田土壤后，土壤固相有机质和有效态氮、磷、钾的动态变化进行了研究。试验结果表明：非腐解有机物施入水田土壤后，在整个土壤淹水期间，水田土壤固相中的有机质、碱解氮、速效磷和速效钾含量都显著增加。非腐解有机物的施用显著增强了水田土壤固相的保肥性和供肥性
After several non-decomposed organic materials were applied to paddy soil, the dynamic changes of soil organic matter and available nitrogen, phosphorus and potassium were studied. The results showed that the content of organic matter, available nitrogen, available phosphorus and available potassium in the solid-phase of paddy soil increased significantly after the non-decomposed organism was applied to paddy soil. The application of non-decomposing organic matter significantly enhanced soil fertility and fertility of paddy soil
