| 摘 要： | 农业灌溉中目前普遍使用节水灌溉技术。采用数值模拟的方法可使灌溉系统内部流场和颗粒运动可视化,同时也可节约开发和运行成本,缩短开发周期。由于灌溉土壤不同,灌溉农作物不同,灌水器结构不同,农作物所需的灌溉量不同,灌溉肥料种类不同等等,通过数值模拟合理配置各类灌溉系统的参数,旨在节约室内及田间试验的时间,更快、更好的设计灌溉系统。

| Abstract: | Currently, water-saving irrigation technology is widely being used in agriculture.Applying the numerical simulation method can make the internal flow field and particle motion in irrigation system visible, and save the cost and the time of the developing and running a water-saving irrigation system.Due to the different kinds of irrigation soil, irrigation crops and irrigation device structure, different needs for crop irrigation quantity, different irrigation fertilizer types, reasonably choosing various irrigation system parameters through the numerical simulation can save the indoor and field test time to faster design a better irrigation system. |
