【摘要】 研究了潮土和红壤中积累态磷的活化动力学及其有机质的影响。四种动力学方程均能很好地描述积累态磷的活化。用H2 O2 去除有机质加快了潮土中积累态磷的活化 ,对红壤影响不明显。施加 2 %葡萄糖培育促进了红壤中积累态磷的活化 ,对潮土影响不大更多还原

【Abstract】 This paper deals with activation kinetics of accmulative phosphorus in fluvoaquic soils and red soils, as is influenced by organic matter. Four kinetic equations can well describe the activation of accumulative phosphorus. Removing organic matter with H 2O 2 accelerated activation of the accumulative phosphorus in fluvoaquic soils, but had no significant influence on red soils. Incubation with addition of 2% glucose promoted activation of the accumulative phosphorus in red soils, but did little in fluvoaquic soils. \;更多还原
