| 摘要: |
| 【目的】探究内镶贴片式滴灌带灌水均匀度和流量降幅与滴灌带铺设坡度、灌水水源含沙量、进水口运行压力的关系，提高灌水均匀度和降低流量降幅，减少滴灌带堵塞。【方法】设计铺设坡度（-1、0、1%）、含沙量（1、2、3 g/L）及运行压力（40、70、100 kPa）三因素三水平的均匀正交试验方案，开展滴灌带长度为35 m的室内物理试验。【结果】灌水均匀度的影响因素大小为：含沙量>铺设坡度>运行压力；流量降幅的影响因素大小为：含沙量>运行压力>铺设坡度；构建了含沙量、铺设坡度及运行压力与灌水均匀度和流量降幅的投影寻踪回归模型，两个模型的标准化均方根误差为2.98%和2.42%，预测模型表现效果极好。【结论】含沙量是影响内镶贴片式滴灌带堵塞的重要因素，以及构建了不同含沙量、铺设坡度、运行压力与灌水均匀度和流量降幅的关系。研究成果可对一定范围内不同含沙量、铺设坡度、运行压力下内镶贴片式滴灌带的灌水均匀度和流量降幅进行预测，在滴灌系统设计和运行理论体系中起到一定的参考作用。 |

| Abstract: |
| 【Objective】The effects of laying slope, sand content, and operating pressure on the irrigation uniformity and flow drop of the inlaid patch drip irrigation belt were explored to reduce the clogging of the drip irrigation belt.【Method】Design a uniform orthogonal test plan with three factors and three levels of laying slope (-1, 0, 1%), sand content (1, 2, 3 g/L) and operating pressure (40, 70, 100 KPa), and carry out the length of drip irrigation belt, It is an indoor physical test of 35 m.【Result】The influencing factors of irrigation uniformity are: sand content > laying slope > operating pressure; the influencing factors of flow drop are: sand content > operating pressure > laying slope. For the projection pursuit regression model of uniformity and flow drop, the standardized root mean square errors of the two models are 2.98% and 2.42%, and the prediction model has excellent performance.【Conclusion】The sand content is an important factor affecting the clogging of the inlaid patch drip irrigation belt, and the relationship between different sand content, laying slope, operating pressure and irrigation uniformity and flow rate drop was established. |
