摘　　要：【目的】研究水肥调控对香蕉生产的影响,探索节水、节肥的栽培技术,以提高香蕉种植的经济效益。【方法】通过田间试验,从水肥调控入手,探讨水肥一体化滴灌施肥、喷水带灌溉加人工撒肥、传统的畦沟灌溉施肥3种水肥管理方式对香蕉生长的影响,并对3种灌溉施肥方式下的经济效益进行比较分析。【结果】在一个香蕉生长周期,与传统的畦沟灌溉施肥相比,水肥一体化滴灌技术每公顷节水2788.1~3164.2t、节肥3582.1~5977.6kg、节本增效17810.05~44806.15元;喷水带灌溉加人工撒肥每公顷节水2716.4t、节肥3582.1kg、节本增效20005.95元。【结论】水肥一体化滴灌施肥和喷水带灌溉加人工撒肥两种灌溉施肥方式均有节水、节肥、增效作用,不同种植人群可根据具体情况选择不同的方式种植香蕉。【Objective】The effects of different water and fertilizer regulation practices on banana production were studied in order to find out a water and fertilizer saving cultivation technology and to increase the economic benefits from banana crop. 【Method】Three treatments, viz., （1） integrated drip irrigation and fertilizer management; （2） irrigation with water-spraying belt and artificial fertilization; （3） ridge fertilization （traditional management）, were used under field conditions and economic benefits were compared. 【Result】During one crop cycle of banana, 2788.1-3164.2 t/ha water and 3582.1-5977.6 kg/ha fertilizer were saved in treatment 1 compared to treatment 3, which resulted in economic benefits of 17810.05 - 44806.15 Yuan/ha. Treatment 2 saved 2716.4 t/ha water and 3582.1 kg/ha fertilizer and resulted in economic benefits of 20005.95 Yuan/ha compared to treatment 3. 【Conclusion】Treatments 1 and 2 both saved water and fertilizer and increased economic benefits from banana production in Nanning City. It was recommended to choose suitable water and fertilizer regulation practices according to local condition.
