摘　　要：以春玉米为供试材料,以传统灌溉方式为对照,研究集雨节灌对土壤水分和作物产量的影响。结果表明,集雨节灌处理下土壤含水率较沟灌、畦灌、沟垄集雨种植分别提高0.58%～1.74%、4.55%～5.14%、3.21%～6.48%。集雨节灌各处理下产量和水分利用效率均高于对应沟灌、畦灌、沟垄集雨种植处理,其中产量分别提高5.03%～15.45%、14.57%～21.85%、2.32%～5.72%,水分利用效率分别提高28.41%～40.23%、39.58%～54.70%、2.99%～5.09%。Spring corn was taken as the material to study the effects of rainfall harvesting planting combined with water-saving irrigation （RHWI） on soil moisture and yield of spring corn with the traditional irrigation modes of furrow irrigation and border irrigation as the control. The results showed that the soil moisture under RHWI increased by 0. 58% - 1. 74%, 4.55% - 5.14%, 3.21% - 6.48% compared to those under furrow irrigation, furrow border irrigation and planting of rainfall harvesting （PRH）, respectively. The average yield and water use efficiency （WUE） under RHWI were higher 5.03%-15.45%, 14.57% - 21.85%, 2.32% -5. 72% and 28.41% -40.23%, 39.58%- 54.70%, 2.99%- 5.09% than those under furrow irrigation, border irrigation and PRH.
