| Abstract: | 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. |
