摘　　要：为研究纳米腐植酸类肥氮素释放特性,以元胞自动机为模拟工具,肥料养分扩散的离散性为理论基础,系统进行了纳米腐植酸缓释肥中氮素在土壤中运移的动态可视化模拟.研究结果表明:元胞自动机模拟的纳米腐植酸肥中氮素释放规律与所选取的两种包膜肥料于25℃下氮素释放特性基本一致,为肥料中氮素释放特性研究提供了有效模拟手段.In order to investigate nitrogen release characteristics of the nanoscale humic acid fertilizers, cellular automata and the spread of fertilizer nutrients discreteness were used as simulation tools and theoretical basis, respectively. Nitrogen dynamic visual simulation was systematically studied by nitrogen migration of nanoscale humic acid fertilizer. The research results showed that the nitrogen release characteristics of cellular automata simulation was consistent between nanoscale humic acid fertilizer and the selection of two kinds of coated fertilizer under 25 ℃. This model provides an effective simulation tool for studying the features in fertilizer nitrogen released characteristics.
