| 摘 要： | 针对传统灌溉方式下大水漫灌所造成的水资源浪费,采用固定道耕作结合垄作沟灌并进行秸秆覆盖的方法,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。结果表明:固定道耕作秸秆覆盖(CTS)处理灌水沟内的水分水平侧渗范围比固定道耕作不覆盖(CT)处理宽约15 cm,在全生育期垄体保持了较好的水分,水分利用效率较CT处理提高3.4%;株高和千粒重优势明显,产量提高11.1%。

| Abstract: | Conventional flat irrigation is widely used in irrigated area,which led to the waste of water resources.Therefore,the controlled traffic tillage with straw cover was adopted based on the ridge culture techniques,by changing flood irrigation to furrow irrigation to study the effect of soil water under controlled traffic tillage irrigation.The ration of ridge and ditch is 2.23 to 1.The results indicate that the width of water side infiltration of CTS treatment(controlled traffic tillage with straw cover)is wider than CT treatment(controlled traffic tillage)15 centimeters approximately,there are better water surroundings under straw cover in whole phenological stages,height and grain weight are higher than CT treatment obviously and WUE and yield is increased by 3.4% and 11.1% respectively. |
