摘　　要：为指导节水灌溉,2010年在上海植物园利用微型蒸渗仪法研究了大花六道木、亮叶忍冬和红叶石楠在不同灌溉水平下的蒸散规律及植物长势。3种植物在不同的灌溉水平下月蒸散量和6～10月总蒸散量差异达到显著水平,说明不同的灌溉水平是影响植物蒸散的重要因素。测量、分析各种植物在4种灌溉水平下的生长和观赏指标,结合各个灌溉水平下的总蒸散量,灌溉水平3(即40%～100%最大持水量)和灌溉水平4(即25%～100%最大持水量)可以满足3种植物对水分的需求,并达到节水灌溉和减少养护的目的。In order to guide the water-saving irrigation of three plant species(Abelia grandiflora,Lonicera nitida Maigrun and Photinia serrulata) for Living Wall in Shanghai,their evapotranspiration rule and growth vigor at four irrigation levels were studied by mini-lysimeter in 2010.There were significant differences in both monthly evapotranspiration and total evapotranspiration from June to October of three plant species among different levels of irrigation treatments,indicating the irrigation is an important fa...
