摘　　要：综述了近年来国内外对草坪硝态氮淋溶问题的研究现状与进展,以及国内草坪施肥管理的研究现状,对有效的减少我国草坪硝酸盐淋失的途径和方法进行了探讨。影响草坪硝酸盐淋溶的因子主要包括:氮肥种类、施氮水平、施肥时间、灌溉、土壤状况等。减少硝态氮淋溶的合理途径有:合理确定施肥量;选择合适的氮肥种类和施肥方式,如使用缓释氮肥,碳/氮比高的有机肥;施用硝化抑制剂;合理的灌溉等。目前,国内有关草坪硝酸盐的研究与国外相比,还较为欠缺,研究适合我国草坪的长效氮肥,制定合理、有效、安全的草坪施肥制度已成为研究发展的趋势。Research advances were reviewed on theories and techniques of turf-grass fertilization in recent years. Focus was given on turf-grass soil nitrate leaching. Effective methods of decreasing nitrate leaching were discussed and comments were made. The reviews show that the influential factors of nitrate leaching are nitrogen source and release mechanism; application rate, time of application, irrigation, soil physical and chemical properties etc. The effective methods to control nitrate leaching were selecting suitable N carriers; appropriate application rate,and the correct application method ;using DCD, reasonable irrigation. Spoon-feedlng philosophy should adopted and slow release N fertilizers should be used in golf putting green management. At present, there are very few researches on nitrate leaching in the field of turf-grass in China. Finding suitable nitrogen fertilizers for turf-grass management is urgently needed. Research tendencies in this area will be developing more reasonable, effective and safe fertilizer programs for different turf types.
