摘要
在宁夏南部干旱山区的试验结果表明 ,集蓄雨水进行有限补充灌溉 ,可以显著提高地膜春小麦的产量和水分利用效率。同时满足作物水分利用效率最高和籽粒产量最大时所需的补充灌水量为 90 mm,满足灌水效率最高时所需补充灌水量为 60 mm。
Limited supplementary irrigation with catchment of rainfall was made for spring wheat mulched with plastic film in dry mountainous areas of South Ningxia. The results showed that it could increase the yield and water use efficiency remarkably, providing 90mm supplementary irrigation required by achieving the highest grain yield and water use efficiency, and 60mm by gaining the best irrigation effect.
