| 摘 要： | [目的]探讨沙地云杉在河西沙区的适应性及其影响因子,为该区生态建设中树种的选择提供依据。[方法]通过对河西地区沙地云杉生长情况的观测研究,以及搜集沙地云杉原产地和其他引种地相关资料,从气候、种子育苗、苗木移栽成活率及生长速度等方面比较分析沙地云杉在河西地区的适应性。[结果]河西地区温度条件适宜沙地云杉生长发育,但降水不足造成的土壤水分亏缺问题必须要通过人工灌水措施加以解决;7a后的沙地云杉生长速度超过原产地白音敖包,适应性强,在农田防护林建设中发展潜力大。[结论]沙地云杉在河西地区具有较大的发展潜力。

| Abstract: | [Objective] The objective of this study is to investigate the adaptability of Picea mongolica and its impact factor, and provide support for tree species selection in ecological construction in Hexi area. [Methods] According to the observation and research on the growth of P. mongolica in Hexi area and the related data of the provenance and introducing area of P. mongolica, we analyzed the adaptability of P. mongolica in Hexi area in terms of climate, seed seedling, seedling transplanting survival rate and growth rate. [Results] The temperature condition of Hexi area was suitable for the growth of P. mongolica, but soil water deficit caused by the lack of precipitation had to be solved by artificial irrigation. The growth rate of 7-year old P. mongolica was faster than that from the source area(Baiyinaobao), and the adaptability was strong, therefore, it showed a great potential in construction of farmland shelterbelt. [Conclusion] Picea mongolica has a great development potential in Hexi area. |
