摘要
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。
In this paper, the dynamic changes of the organic matter and the available nutrients in solid phase of the paddy soils after the undecomposed organic materials were studied The results showed that the organic matter content and the available N、P and K contents were greatly increased by application of the organic materials during entire flooding period The application of the undecomposed organic materials improved the capability of the soil solid phase preserving and supplying nutrients
