摘　　要：随着设施农业的快速发展,设施土壤普遍出现次生盐渍化、养分失调、土壤板结等退化问题。引发的根区氧气含量不足已经成为制约设施农业生产力的主要因素之一。加氧灌溉通过向灌溉水中掺入空气或氧气,以直接向作物根区输氧的形式提高根际氧气含量,从而实现作物产量与品质的提升。纳米气泡作为一种高效加氧方式,在农业领域的应用逐渐引起人们的广泛兴趣,也取得了良好的应用效果。目前,关于纳米气泡产生方法、表征手段、在水处理以及矿石浮选方面的应用等已经被竞相报道,然而对于纳米气泡在农业领域的效果与应用还鲜有概述。综述聚焦于纳米气泡特性,以及纳米气泡灌溉对设施作物生长、产量、品质、土壤理化指标与土壤微生物的影响,对纳米气泡在设施农业领域的现有研究成果进行了总结,并对未来纳米气泡在农业领域的研究重点提出了展望。With the rapid development of facility agriculture,soil degradation such as secondary salinization,nutrient imbalance,and soil compaction has emerged in facility cultivation.Consequently,greenhouse crops usually suffer from oxygen deficiency in the rhizosphere,and hypoxic stress has become a major constraint hampering crop production in facility.Aerated irrigation,i.e.,oxygenation of irrigation water,directly delivers the oxygen to the plant root zone,thereby increasing crop yield and quality.Nanobubbles(NBs)irrigation is considered as one of the most efficient aerated methods,and its application in agricultural field has attracted extensive attentions.At present,the generation ways,observation methods,and the applications of NBs in water treatment and ore flotation have been successionally reported.However,the effects and applications of nanobubbles in agriculture are rarely reviewed.This review focuses on the characteristics of nanobubbles,and the effects of nanobubble irrigation on the growth,yield,quality,soil physical and chemical indexes and soil microorganisms of facility crops.It summarizes the existing research results of nanobubbles in the field of facility agriculture,and puts forward the prospects for the future research focus of nanobubbles in the field of agriculture.
