| 摘 要： | 针对传统灌溉方式下大水漫灌所造成的水资源浪费，采用春小麦垄作结合地膜覆盖的方法，改传统耕作的大水漫灌为小水沟内侧渗灌，设置垄沟比例为2．23：1。试验结果表明：地膜覆盖增强了水分向垄体的侧渗，减少了水分的向下入渗，垄体水分侧渗范围比不覆盖宽约10～15cm，灌水沟水分下渗深度为100cm。水分利用效率较不覆盖的提高了6．5％，株高、穗粒数和千粒重都高于不覆盖处理，产量提高了6．7％。

| Abstract: | Aiming at the water resources waste of conventional flood irrigation, ridge culture combining with film mulching for spring wheat was applied in this paper. The irrigation method was changed from flood irrigation into furrow irrigation, and the ration between ridge and ditch was set as 2. 23/1. The experimental result indicated that under the condition of film mulching, the capacity of side infiltration was enhanced ,while the capacity of vertical infiltration was reduced , the range of soil water side infiltration was wider than uncover treatment about 10- 15 cm, the depth of water vertical infiltration in ditch was 100 cm. Compared with uncover treatment, the water use efficiency was increased by 6. 5%, the plant height, the quantity of grain per ear and 1000-grain weight were higher, and the yield was increased by 6.7%. |
