节水耕作措施在旱作农田中研究的相对较多 ,而在灌溉农田上则较少研究。本文重点探索在灌溉农田上 ,节水耕作措施 (免耕 )与高效节水管灌技术相结合 ,充分发挥耕作措施与灌溉技术的节水潜力和优势 ,提高农田水分利用效率。试验结果表明 :同常规耕作相比 ,玉米全程免耕下棵间蒸发的无效耗水可降低 2 7.6% ;农田水分利用效率提高幅度达 18.9% ;同时 ,免耕措施具有明显的省工和节能效果 ,耕作成本可降低 52 .9%～ 74.3%。 There are relatively few studies on water-saving farming practices in dry farmland, but less on irrigated farmland. This paper mainly explores the combination of water-saving and tillage (no-tillage) and water-efficient pipe irrigation in irrigated farmland, giving full play to the water-saving potential and advantages of tillage measures and irrigation technologies, and improving the water use efficiency of farmland. The results showed that compared with conventional tillage, the ineffective water consumption of evapotranspiration among maize under whole tillage could be reduced by 2 7.6%; the water use efficiency of farmland increased by 18.9%; meanwhile, no-tillage measures had obvious labor-saving and energy-saving Effect, farming costs can be reduced by 52.9% ~ 74.3%.
