摘  要：
为研究不同灌溉定额下地下渗灌对干旱地区枣树生长、产量和水分利用效率的影响,以5 a生枣树为研究对象,设不同灌溉定额(828、1 248、1 668 m~3/hm~2)和不同灌溉方式(地下渗灌、地面滴灌、管灌)2因素3水平的田间试验。结果表明:灌溉定额相同时,与地面滴灌和管灌相比,地下渗灌能够促进枣树新梢直径、枣吊长度和座果率的增长,同时枣树产量提高2.84%～25.70%,水分利用效率提高8.02%～18.96%。地下渗灌条件下,灌溉定额从1 248 m~3/hm~2提高为1 668 m~3/hm~2时枣树产量和水分利用效率反而分别降低2.47%,8.84%。因此,地下渗灌在灌溉定额为1 248 m~3/hm~2时更适宜枣树生长,该处理产量最高(9 418.85 kg/hm~2),水分利用效率最高(3.84 kg/m~3),研究成果可为地下渗灌技术在干旱区推广提供理论依据。

摘  要：
To study the effects of subsurface irrigation on the growth, yield and water use efficiency of jujube trees in arid areas under different irrigation quotas, field experiments were conducted with 5 years old jujube trees under different irrigation quotas(828, 1 248, 1 668 m~3/hm~2) and different irrigation methods(subsurface infiltration irrigation, surface drip irrigation, pipe irrigation) with 2 factors and 3 levels. The results showed that: compared with surface drip irrigation and tube irrigation, subsurface infiltration irrigation could increase the diameter of new shoots, the length of jujube slings and the fruit setting rate of jujube trees, and increase the yield of jujube trees by 2.84%～25.70%, and increase the WUE by 8.02%～18.96%; under subsurface infiltration irrigation, when the irrigation quota increased from 1 248 to 1 668 m~3/hm~2, the yield and WUE of jujube decreased by 2.47% and 8.84% respectively. Therefore, subsurface infiltration irrigation is more suitable for the growth of jujube trees when the irrigation quota is 1 248 m~3/hm~2. This treatment has the highest yield(9 418.85 kg/hm~2) and the highest water use efficiency(3.84 kg/m~3). The research results can provide theoretical basis for the popularization of subsurface infiltration irrigation technology in arid areas.
