A new water-saving irrigation technique-sophon surge flow irrigation method for well-irrigation districts is put forward in this paper,which makes use of a regulating pond and a set of system for producing surge flow ,and intermittent flow occurs from outlet of the low-pressure pipeline automatically,then surge flow can be achieved.

In view of the fact that the availability of well water and the electric energy comprehensive utilization rate are low in surface irrigation under low pressure pipeline of water delivery; a new idea of applying frequency control technology to a low pressure pipeline was proposed in this paper, which allows the pump to operate under the condition of constant discharge at varied pressures.
