摘要
以半湿润易旱区灌溉冬小麦为对象,对比分析了田间根域集雨(免灌)种植、集雨补灌种植、传统平地旱作及水平畦灌方式下冬小麦产量和水分利用效率的变化。结果表明,根域集雨(免灌)种植较平地旱作可显著提高冬小麦产量及水分利用效率,增产节水效果显著;集雨补灌种植下产量较畦灌差异不显著,但显著提高了水分利用效率。集雨节灌种植方式在保证产量的基础上,可实现雨水和灌溉水的高效利用。
The yield and water use efficiency of winter wheat in sub-humid areas were analyzed comparatively under the modes of root domain rainfall harvesting (no irrigation), rainfall harvesting with supple-mentary irrigation, traditional rain-fed cultivation and border irrigation cultivation. The results showed that root domain rainfall harvesting (no irrigation) cultivation could significantly increase the yield and water use efficiency of winter wheat compared to traditional rainfed cultivation. There was no significant difference of the yield between rainfall harvesting with supplementary irrigation and border irrigation cultivation, but water use efficiency increased significantly under rainfall harvesting with supplementary irrigation and border irrigation cultivation compared to border irrigation cultivation. On the basis of high yield, rain water and irrigated water were used efficiently under rainfall harvesting with water-saving irrigation cultivation.
