摘　　要：我国大部分地区处于干旱和半干旱地区,发展节水农业是我国农业发展的必然趋势。保水剂由于其高吸水性和良好的保水能力,有效的满足了我国发展节水农业的要求,在农业生产中受到了越来越多的重视,具有广阔的应用前景。简述了保水剂的发展概况、作用原理进行,重点讨论了其在农业上所发挥的保水保墒、改良土壤、保肥以及增效等作用,同时对保水剂在农业应用研究中存在的问题进行了探讨。As most regions of china are in the arid and semi-arid region, developing water-saving agriculture is an inevitable trend in china＇s agricultural development. Owing to the super water absorption, good water-holding capacity and effectively meeting the requirements of china＇s water-saving agriculture, water retaining agents has got more and more attention and thus has wide application prospects. This paper simply described the history and mechanism of water retaining agent, and detailedly analyzed its effects in agriculture, such as water conservation, soil improvement, nutrient preservation and synergy effect on fertilizer. The problems in the current agriculture applications are also discussed.
