单翼迷宫式滴灌带的关键参数与灌水均匀度的响应关系

为探究单翼迷宫式滴灌带坡度、进水压力和铺设长度对灌水均匀度的影响,以3种单翼迷宫式滴灌带为研究对象,以灌水均匀度作为评价指标,采用UL₉(3⁴)均匀正交设计试验,比较了3种不同流量的单翼迷宫滴灌带在进水压力、铺设长度和坡度作用下的灌水均匀度的变化规律。经直观分析、方差分析和多重比较进行综合评价,再由SPSS和PPR对试验数据进行数学建模。结果显示,3种单翼迷宫式滴灌带灌水均匀度的外界因素排序均为压力>坡度>长度,相比于SPSS、PPR所建立的模型具有更高的精度。研究成果不仅为灌水均匀度计算与预测提供了理论依据,还对各学科试验优化设计、高维数据建模分析提供了有效的解决方案。

Response Relationship between Key Parameters of Single-wing Labyrinth Drip Irrigation Belt and Irrigation Uniformity

In order to explore the influence of single wing labyrinth drip irrigation belt slope,water inlet pressure and laying length on irrigation uniformity,this paper took three kinds of single-wing labyrinth drip irrigation belts as the research object and irrigation uniformity as the evaluation index,and the orthogonal test was designed to compare the variation law of irrigation uniformity of single-wing labyrinth drip irrigation belts with three different flow rate under the influence of water inlet pressure,laying length and slope.The comprehensive evaluation was carried out by visual analysis,variance analysis and multiple comparisons,and then the mathematical modeling of the test data was carried out by SPSS and PPR.The results showed that the order of the external factors of the irrigation uniformity of the three kind of single-wing labyrinth drip irrigation belts was pressure>slope>length;the model established by PPR had higher accuracy compared with SPSS.The research results not only provide a theoretical basis for the calculation and prediction of irrigation uniformity,but also provide an effective solution for the experimental optimization design of various disciplines and the modeling and analysis of high-dimensional data.
