【摘要】：基于北京市郊区县设施蔬菜用水现状与农户节水行为的调研,采用DEA方法对采用节水技术的北京设施蔬菜投入产出效率进行了评价。结果显示,基于节水的京郊设施蔬菜生产效率为0.900,处于较高水平,但设施黄瓜和设施茄子仍存在10.212%、0.285%的节水提升潜力;基于膜下滴灌、水肥一体化、畦灌等技术设施蔬菜生产已发挥最佳投入产出的配置效率,但基于沟灌、膜下沟灌、膜下微喷的设施蔬菜仍存在2.902%、12.162%和2.792%的节水提升潜力。结论表明,不同的设施蔬菜品种、节水技术选择对于设施蔬菜生产效率存在差异性,通过调整结构和创新技术,可提升设施蔬菜节水效率。
[Abstract]:Based on the investigation of the present situation of vegetable water use and household water-saving behavior in suburban counties of Beijing, the input-output efficiency of protected vegetables in Beijing using water-saving technology was evaluated by DEA method.The results showed that the vegetable production efficiency was 0.900 in Beijing suburb based on water saving, but the water saving potential of greenhouse cucumber and eggplant was still 10.2120.285%, and based on drip irrigation under film, the integration of water and fertilizer.The vegetable production of border irrigation and other technical facilities has played the best input-output allocation efficiency, but based on furrow irrigation and submembrane furrow irrigation, there is still 2.902% 12.162% and 2.792% water-saving potential for the facility vegetables with micro-spraying under film.The results showed that the selection of water-saving techniques had different effects on the production efficiency of greenhouse vegetables, and the water-saving efficiency of protected vegetables could be improved by adjusting the structure and innovating the technology.
