Water high efficiently utilization pattern and demonstration for canal irrigation farmland

This paper was based on the summary of the special topic research project of "Water High-Efficiency Utilization Pattern and Demonstration for Canal Irrigation Farmland" from the national "Ninth Five-Years-Plan", as well as the work of demonstration zone construction and management. The basic idea for achieving high efficiency utilization of water in canal irrigation farmland is put forward first, based on the analysis of the present problems in this area. Some techniques and measurements were found to improve the water use efficiency during water delivery, irrigation in field, and water production efficiency. Secondly, the water high efficiency utilization pattern as well as the demonstration model was presented. This utilization pattern was proved to be high efficient by the demonstration model. The demonstration project results show that this utilization pattern has great significance for practical application and demonstration.
