Contrastive Research on Single Plant Water-consumption Quantity of Main Landscape Shrub in Beijing

LI Xin-yu,LAI Na-na,QIE Yi-bin,LIN Yan(Beijing Institute of Landscape Gardening,Beijing,100102 China)  
Single plant water consumption rules and growth performances under different irrigation conditions of six kinds of landscape shrub in Beijing,namely Euonymus japonicus,Lonicera maacki,Swida alba,Buxus microphylla,Euonymus kiautschovicus and Kerria japonica,were studied by means of potted weighing method.The result showed that according to water consumption quantity,the six kinds could be divided into three categories,namely high water consumption type,low water consumption type and middle water consumption type.Euonymus japonicus was high-water consumption type,Lonicera maackii and Swida alba were low water consumption type,Buxus microphylla,Euonymus kiautschovicus and Kerria japonica were middle water consumption type.Different irrigation treatment had significant influence on the water consumption quantity of the six kinds,as P0.001.The water consumption quantity of the six kinds showed ordinal decrease tendency with the increase of drought stress.Two indexes,namely plant photosynthesis rate and leaf area,could be selected to evaluate plant water lacking degree.Plant photosynthesis rate had linear relation with irrigation water quantity.The more irrigation water quantity was,the larger plant photosynthesis rate was and the better plant shape was.Leaf area showed significant correlation with irrigation level.So it also was a good index to reflect the plant water lacking degree.
