Abstract:
Pinus bungeana,Platycladus orientalis,Sabina chinensis and Sabina vulgaris were used as test materials.In order to measure the water-consumption characteristics of seedlings′transpiration,this experiment used potted plants weighing method and studied the effect of vapor pressure deficit and leaf stomatal conductance on the seedling transpiration water-consumption.The results showed that the use efficiency of water for nursery stocks overall was declining under the condition of adequate soil water supply.The average daily use efficiency of water for nursery stocks overall performanced for Pinus bungeana(3.01 μmol?mmol-1)>Platycladus orientalis(2.62 μmol?mmol-1)>Sabina vulgaris(2.57 μmol?mmol-1)>Sabina chinensis(2.35 μmol?mmol-1).The ability of water-consumption for transpiration was sunny>half sunny>cloudy in the typical weather;the capability of daily water-consumption for transpiration of seedlings day and night was Pinus bungeana(0.030 g?cm-2?d-1)>Sabina vulgaris(0.026 g?cm-2?d-1)>Platycladus orientalis(0.018 g?cm-2?d-1)>Sabina chinensis(0.008 g?cm-2?d-1).The water-consumption of transpiration for nursery stocks,vapor pressure deficit and stomata conductance were positively correlated relationship,which biggest affected was Pinus bungeana.The results of the study were a gist for scientific evaluations for water-consumption of landscape greening tree species and could improve the utilization efficiency of water for landscape greenbelt.
