| 中文摘要 | 为了比较不同树种叶片的吸水性能,在陕北黄土丘陵沟壑区采用浸水法测定刺槐、臭椿、小叶杨、新疆杨、河北杨、84K杨(银白杨×腺毛杨)6种常见树种叶片的吸水能力。结果表明:1)不同树种叶片的吸水量均随浸水时间的增加而增加,与浸水时间呈对数关系;吸水速率均随浸水时间的增加而降低,与浸水时间呈幂函数关系;叶片浸水后0～60 min吸水速率较大,是叶片的主要吸水阶段。2)不同树种叶片吸水量、吸水速率表现为:新疆杨>刺槐>84K杨>臭椿>河北杨>小叶杨,其中新疆杨叶片的吸水量为0.415 g/g,小叶杨为0.179 g/g。3)不同树种中,新疆杨的吸水量、吸水速率最大,新疆杨在树冠截留方面应具有更重要的作用。 |
| 英文摘要 | In order to compare the water absorption of different trees leaves，the water absorption capacity and water absorption rate of leaves of Robinia pseudoacacia，Ailanthus altissima，Populus simonii， Populus bolleana，Populus hopeiensis，Populus alba × Populus glandulosa were measured by using water immersion method in loess hilly and gully region of Northern Shaanxi． The results showed that: 1) Water absorption capacity of 6 species leaves all increased with immersed time，and their relationship performed as logarithmic function; while water absorption rate decreased with immersed time，performing as power function． The water adsorption rate was the highest within 0 － 60 min after leaves immersed in water， which was the critical stage for leaves to absorb water． 2) The sequences of water absorption capacity and water absorption rate were both as followed: Populus bolleana ＞ Robinia pseudoacacia ＞ Populus alba × Populus glandulosa ＞ Ailanthus altissima ＞ Populus hopeiensis ＞ Populus simonii，the water absorption capacity of P． bolleana and P． simonii leaves were 0. 415 and 0. 179 g /g respectively． 3) On the aspects of water absorption capacity and water absorption rate，P． bolleana leaves were the highest among 6 species，and P． bolleana plays a more important role in crown interception． |
