| 摘 要： | 本文以目前引种较多的20个优良杨树无性系为研究对象，通过栽植对比试验，借助林分全面调查和树干解析等方法，研究各无性系树高、胸径和材积生长特性，以期获得各无性系的生长特性表现差异，为试验区杨树栽培品种的选择提供科学依据。结果表明：中驻6号为最适于试验地区推广栽植的无性系，50杨、桑迪、NL351表现也较好，可供选择；I-107和中洛759不宜在试验区栽植。无性系中树干饱满度最高的为无性系2001，饱满度最低的为无性系102。

| Abstract: | 20 superior poplar clones serve as our research objects. We investigate their tree height, DBH (diameter at breast height) and volume growth property by planting contrast test, comprehensive investigation and stem analysis to get their growth difference. This can provide scientific reference for poplar selection in experimental area. Experimental results show that Zhongzhu 6 is the most suitable clone. 50 Yang, sandy and NL351 exhibit well. I-107 and Zhongluo 759 are not suitable for the test area. Clone 2001 has the highest trunk plumpness while clone 102 has the lowest trunk plumpness. |
