Abstract：The irrigation district is the smallest unit of drip irrigation system, whose design will directly affect the project investment, operating costs and safety reliability.[Objective]Optimalize the layout of pipe network of ro-tation irrigation with branch pipe.[Method]The network was considered as a whole in this study. The model was established based on the minimum investment per unit area and the maximum control area. Meanwhile, the genetic algorithm was used to complete optimization calculation.[Result]Compared with one-way capillary tube, the two-way capillary unit area investment was reduced by 4.31％, and the control area was increased by 28.41％;Under the condition of water supply, when the pipe diameter increased from 32 mm to 75 mm, the con-trol area increased by 393.78％. When the pipe diameter was reduced from 75 mm to 32 mm, the minimum invest-ment was reduced by 11.50％.[Conclusion]The bidirectional laterals is better than unidirectional one in both control area and unit area investment;Increasing diameter of branch pipe is conducive to increasing irrigation ar-ea control area to and reducing diameter of branch pipe is conducive to reduce the unit area investment.
