| 摘 要： | 为了提高毛白杨良种基地建设质量,对天水码头苗圃培育的1609号毛白杨生长状况进行跟踪研究,选择1609号毛白杨标准木进行树干解析,分析和研究引种该树种16年后,其胸径、树高和材积生长状况。结果表明：1609号毛白杨在养分贫瘠的沙质盐碱土上不仅生长量大,而且有较强的抗逆性和适应性,虽在该区域生长16年,但还未达到数量成熟阶段,具有一定的生长潜力和培育价值。

| Abstract: | In order to search the growth status of asexual families of Populus tometosa 1609 that planting at Matou nursery in Tianshui. On the basis of fully investigation, the sample trees were selected and conducted trunk analysis and explored its growth laws in terms of breast diameter, height of trees and stem volume. The result showed that Populus tometosa1609 has a rapid growth, big increment, stronger resistance and adaptability compared with other species in the salt sandlot lack of nutrient. In spite of 16 years growing in this area, it is still not an age of quantitative maturity, but it has some growth potentials, and would be a promising species to be cultivated in the northwest area. |
