摘要
本文以溶质运移理论为基础，建立了淹水稻田中氨态氮（－Ｎ）运移、转化的数学模型，并以室内土柱试验进行了验证．应用该模型模拟计算了控制不同稻田中渗漏强度、施肥管理制度下淹水稻田中（－Ｎ）的运移及分布动态．可为拟定合理的水肥管理措施提供依据．
Based on the theory of solute transfer a mathematical model for NH-N transformation and movement in flooding paddy soil is established and verified by experiments in laboratory.The pattern of transfer and distribution of NH-N in flooding soil under different seepage rate and ragime of fertilizer application are investigated by numerical simulation.Measures for effective use of fertilizer and management of field water are also discussed.
