摘　　要：作为一种高效的灌溉技术,增氧灌溉技术能提高作物的产量、提高水资源利用效率、提升作物品质,在农业领域应用广泛。增氧灌溉可以提高植物根际氧含量,增强作物根系呼吸作用,提高好氧型微生物的相对丰度,增强土壤肥力,改变土壤中的微生物结构。由于土壤环境的复杂性,不同作物间的差异性,农艺方式和增氧方式的不同,导致增氧灌溉技术效果差异较大。基于此,分析了目前国内外增氧灌溉技术的应用现状,尤其是在水稻种植领域的应用情况,探讨了后续增氧灌溉技术发展的路径,以期为增氧灌溉技术的应用提供参考。Oxygenated irrigation as a new irrigation technology,can increase crop yield,improve water use efficiency,and crop quality,and was widely used in agriculture.Oxygenated irrigation increases oxygen content in rhizosphere,thus,enhances crop root respiration,increases the relative abundance of aerobic microorganisms,promotes nitrification,nitrogen fixation,enhances soil fertility,and changes the soil microbial structure.Due to the complexity of the soil environment,crops diversity,and the various method of agronomic and oxygenation,the effect can be very different.Summarized current status both domestic and overseas for oxygenated irrigation,especially application in rice planting area,and the possible development of oxygenated irrigation,for future reference.
