摘　　要：利用Lcro+便携式光合仪,对青岛市3种主要灌木树种连翘、金银木、锦带花的蒸腾耗水规律进行了测定和研究。结果表明:在水分充足条件下连翘呈典型的双峰曲线,金银木和锦带花呈单峰曲线;金银木在1 d的各时间段耗水速率明显高于连翘和锦带花的耗水速率;3种灌木晴天的耗水速率明显大于阴天的耗水速率;此外,在春季,连翘对土壤含水量比金银木、锦带花敏感。试验的结果能够为植物的合理选择、水分的量化管理提供科学依据。In this study, Lcpro＋portable photosynthesis system was adopted, the three major shrub species in Qingdao Forsythia suspensa ,Lonicera maackii, Weigela florida transpiration water consumption was measured and studied. The results indicated that in the water sufficient conditions, Forsythia suspensa was a typical bimodal cttrve, Lonicera rnaackii and Weigela florida were a single peak curve; Lonicera maackii all in one day time rate of water consumption was significantly higher than Forsythia and Weigela water consumption rate; three kinds of shrubs the water consumption rates in sunny were significantly greater than cloudy water consumption rates. In addition, in spring the Forsythia on the soil moisture was more content than Lonicera and Weigela. Test results could provide scientific reasonable irrigation, and could make full use of green plants choice.
