中文摘要： 南疆地区由于自然条件优越已成为我国重要的优质红枣生产基地，但由于缺乏对不同自然条件下枣树水肥、树体的科学管理，使红枣品质大幅降低。项目以南疆地区种植面积最广的骏枣为研究对象，利用土壤-植物-大气连续体（SPAC）分析方法，结合南疆地区气象因素和土壤环境对枣树的作用规律，建立枣树冠层蒸发蒸腾模型（枣树冠层结构模型和蒸发蒸腾模型耦合）、枣树三维根系吸水模型（根系三维生长分布模型和根系吸水模型耦合）和NPK综合动力学模型，依据实测数据对以上三个子模型进行校正，最终建立水分养分综合效应三维动力学模型，并在VC++开发环境下，以三维图像操作函数OpenGL和NURBS曲线为工具，实现南疆地区骏枣水分养分效应动力学三维动态模拟。项目研究成果对揭示骏枣水分养分效应的作用机理和合理有效的灌溉施肥具有重要的指导意义和实用价值。

英文摘要： Due to the superior natural conditions, the southern XinJiang has become an important production base of high quality red dates. However, the red jujube has significantly declined in the quality due to the lack of scientific management of the jujube tree fertilizer under different natural conditions. This project studies on the Junzao which is widely planted in the southern border region, by the use of the soil-plant- atmosphere continuum (SPAC) analysis, combined with the role of the law of the meteorological factors and soil environment of the southern border region of the jujube tree to set up the jujube tree canopy evapo transpiration model (Jujube tree crown structure model and evapotranspiration model coupling); jujube three-dimensional root water uptake model (three-dimensional root growth and distribution model and root water uptake model coupling) and NPK comprehensive dynamic model. According to the actual measurement of the above three sub-models correction, the combined effect of three-dimensional dynamic model of water and nutrient is finally established. And under VC++ development environment, using the 3D image manipulation functions, OpenGL and NURBS curves, we can make the three-dimensional dynamic simulation of the southern border region red jujube on water and nutrient effects.The research results has an important guiding significance and application value on the reveal the mechanism of the water and nutrient effects of red jujule and on how to irrigate and fertilize properly and effectively.
