Research on Assembly Matching Technology of Efficient Mixed Irrigation Systems in Well Irrigation Area of Shiyang River Basin

Through matching high-effective water-saving and frequency control technology of sprinkler irrigation,drip irrigation and pipe irrigation,the paper adopted scheme of constant variation to study the relationship of various irrigation techniques between flow and pressure,which to search optimize mode for well irrigation area in Shiyang River basin.The results show that the efficiency of water pump is rather higher under the rotation speed of water pump as 1 710 r/min for sprinkler irrigation,drip irrigation and pipe irrigation.It's a way to solve the contradiction of local irrigation method between the adjustment of planting structure and improving the working conditions compression equipment and irrigation equipment.In the meanwhile,it also shows that the parameter calculator formula and method about constant variation of whole water pump are reliable.
