| 摘 要： | 建立了冬小麦生长、根系吸氮耦合模拟模型。冬小麦生长动态受到气象、土壤水分、氮肥等外界因素和作物吸氮能力等内在因素的影响 ,而作物吸氮量与干物质增长量和土壤水分、氮肥条件也有着密切的关系。模拟结果表明 :该模型能够较好的反映冬小麦生长动态、叶面积指数变化及作物吸氮过程

| Abstract: | A dynamic simulation model for soil plant system was developed. The model consists of two sub models: biomass formation sub model and nitrogen uptake sub model. Two sub models are coupled to describe dry matter transformation and formation in soil plant system. Comparing the simulated results with the experimental data, including dry matter amount, leaf area index and nitrogen accumulated in shoot part in winter wheat shows that the simulation model is satisfactory. |
