摘　　要：[目的]针对传统常规施肥存在肥料利用率低、用工量大的问题,研究柑橘水肥一体化技术对产量和效益的影响,以达到节肥、省工、增效的目的。[方法]以广西壮族自治区柳州市柳城县种植的早熟温州蜜柑(宫川)、柳城蜜橘、沙糖橘为试材,采用配方肥与滴灌结合的水肥一体化施肥方式,统计不同处理对产量和效益的影响。[结果]采用水肥一体化不同施肥处理,与对照相比,处理①、处理②、处理③化肥使用成本分别下降了55.04%、39.96%和24.98%,人工成本下降了68.89%,产量则有较大幅度的增加。其中,以处理②效果最佳。[结论]传统常规施肥存在肥料利用率低、浪费大、用工多的问题。采用水肥一体化技术是一个较好的解决途径。[Objective] Aiming at the problems of low fertilizer utilization rate and large amount of labor by the traditional fertilization technique,the effects of yield and benefit on the citrus were studied by integration technology of water and fertilizer,which achieved the purpose of the saving fertilizer and work,and the increasing efficiency.[Method] As the test materials of the precocious Gongchuan mandarin,Liucheng tangerine and Satang tangerine in Liucheng County,Liuzhou City,Guangxi Province,the effects of yield and benefit of different treatments were counted up by the technology of the formula fertilizer combined with drip irrigation.[Result] By the technology of the formula fertilizer combined with drip irrigation,compared with the control,fertilizer use cost of treatment①,treatment② and treatment③ decreased by 55.04％,39.96％ and 24.98％ respectively,labor costs decreased by 68.89％,production has greatly increased.Among them,the best effect was treatment ②.[Conclusion] Using the traditional fertilization technique had the problems of low fertilizer utilization rate and large amount of labor,a better solution way was used by the technology of the formula fertilizer combined with drip irrigation.
