| Abstract: |
| 【Objective】The objective is to reasonably divide the field pipe network construction scale of multi-level gravity drip irrigation system, which minimizes the comprehensive cost.【Method】Taking the lowest comprehensive cost per unit area considering the service life of the project as the objective function and taking the pipe network layout, pipe diameter, flow and pressure as constraints, the construction scale optimization mathematical model of field pipe network project of multi-level gravity drip irrigation system was established and solved by atom search optimization (ASO).【Result】Taking the gravity two-level drip irrigation project of Xinjiang as an example, this method was used to optimize its field pipe network construction scale. The results showd that when the field pipe network engineering is 89 hm2, the total cost of comprehensive cost per unit area is the lowest, and it is excellent when the construction scale is 74 hm2 to 101 hm2. At the same time, the optimal project scale under different emitter spacing, different capillary spacing and different design flow of emitter was calculated and analyzed. The results showed that the combination of the three is different, the optimal scale is different, the corresponding length-width ratio of field ranges from 1.00 to 1.30, and the comprehensive cost per unit area of the optimal scale decreases with the increase of emitter spacing or capillary spacing, and increases with the increase of emitter design flow.【Conclusion】This method can be optimized for the construction scale of field pipe network project of multi-level gravity drip irrigation system. In addition, the atom search optimization algorithm is stable, and its calculation speed is fast and the calculated accuracy is high. The proposed method has a certain value of the optimization design of the gravity drip irrigation network system. |
