摘要
通过田间灌溉试验和计算机模拟 ,对景泰提水灌区现行地面灌水技术进行了评价 ,研究对比了地面灌溉田间灌水效率的 2种计算方法。用模拟地面灌溉水流运动的计算机模型模拟灌溉试验 ,得到平均灌水均匀度和田间灌水效率 ,并针对灌区田间灌水技术存在的问题 。
Through farm irrigation experiment and computer simulation, the current surface irrigation technique in jingtai pumping irrigation district is evaluated. Two kinds of calculation methods for farm irrigation efficiency of surface irrigation are researched and compared. By using surface irrigation water movement computer Simulation model to simulate irrigation experiment, the average irrigation uniformity and farm irrigation efficiency are obtained. Aiming at the existing problems in farm irrigation technique of irrigation district, suggestions for improvement are proposed.
