摘　　要：对小麦、玉米一体化垄作沟灌种植模式的垄宽、沟深、沟宽和田面坡度4个灌水技术要素进行正交试验,研究其水流推进规律及灌水质量评价指标,通过极差分析优化技术要素组合。结果表明,田面坡度和垄宽的影响最大,沟宽和沟深影响较小,较为合理的技术要素组合为垄宽70cm、沟宽40cm、沟深20cm和坡度2‰。Experiments were conducted to test on ridge width, ditch depth, ditch width and field surface slope of wheat and corn integration ridge and furrow planting mode, and study the water promote regularity and quality of irrigation evaluation. The technical combination of elements was optimized by the range analysis. The results showed that： field surface slope and ridge width were the main influent factors, and ditch width and ditch depth became second. Combination with the ridge width of 70 cm, ditch width of 40 cm, ditch depth of 20 cm and slope of 2‰ was more reasonable.
