摘　　要：对杜鹃、桂树、月季3种不同耗水等级的盆栽进行蒸腾量和土壤蒸发量的测定实验,合理估算出了3种盆栽的需水区间,结合北京市家庭盆栽浇灌情况调查的统计结果对北京市盆栽节水潜力进行分析.结果表明:截止到2010年11月份,北京市家庭盆栽节水潜力区间为1.93×106～2.61×106 t,占北京市年生活用水量的比例区间为0.13%～0.18%,而且其节水潜力将随着家庭绿化的普及而逐渐增大.该研究结果对提高人们对家庭盆栽节水效益的认识和推广使用盆栽节水器具有重要意义,也为盆栽的日常浇水提供了理论依据.Water demand of three pot plants,azalea,cherry bay and Chinese rose,were estimated.Transpiration rates and soil evaporation rates were measured.Water saving potential was analyzed from a survey on pot plant watering.It was found that up to November 2011,water saving potential was from 1.93×106 to 2.61×106 t,amounting to 0.13% to 0.18% of total water consumption in Beijing annually.Further,water saving potential is likely to increase with the spread of family greening.This work has important implications for heightening the awareness of water conservation and use of water-saving devices for pot plants.This work also provides a theoretical basis for daily watering of pot plants.
