- 摘要:
- 以白皮松、侧柏、桧柏和沙地柏为试材，采用盆栽称重方法，研究了水汽压亏缺与叶片气孔导度对苗木蒸腾耗水的影响，以期测得苗木的蒸腾耗水特性。结果表明：在土壤水分充足的情况下，苗木的水分利用率总体呈下降趋势，苗木日平均水分利用率表现为白皮松（3.01 μmol?mmol-1）＞侧柏（2.62 μmol?mmol-1）＞沙地柏（2.57 μmol?mmol-1）＞桧柏（2.35 μmol?mmol-1）。3种典型天气中，苗木蒸腾耗水为晴天＞半晴天＞阴天。苗木昼夜蒸腾耗水排序为白皮松（0.030 g?cm-2?d-1）＞沙地柏（0.026 g?cm-2?d-1）＞侧柏（0.018 g?cm-2?d-1）＞桧柏（0.008 g?cm-2?d-1）。苗木的蒸腾耗水与水汽压亏缺、叶片气孔导度呈正相关关系，受其影响最大的是白皮松。研究结果可为科学评价园林绿化树种耗水状况、提高园林绿地水分利用率提供参考依据。
- 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.
