农业节水耕作措施在旱作农田中研究相对较多，而在灌溉农田上的研究则较少，通过对低压管道灌溉条件下，深耕措施对农田水分利用效率的影响研究，重点探讨节水灌溉的水利措施与农业措施相结合，使其优势互补，最大限度地调控农田水分利用状况，提高农田水分利用效率。试验结果表明，深耕措施比常规耕作产量提高17．9％，农田水分利用效率提高19．5％，节水27．6％。
The research on agricultural water-saving cultivation has relatively more research in dry farmland, but few in irrigation farmland. Through the research on the effect of low-pressure pipeline irrigation on farmland water use efficiency, the paper mainly discusses water-saving irrigation Of the water conservancy measures and agricultural measures combined to make it complementary to each other to maximize the regulation of farmland water use and improve farmland water use efficiency. The results showed that the depth of tillage was 17.9% higher than that of conventional tillage, the water use efficiency of farmland increased by 19.5% and the water saving was 27.6%.
