摘要
采集山杨主要分布区内15个种源171份材料，在黑龙江省迎春林业局进行种源试验，并进行生长与纸浆材性的综合分析，其结果表明：种源树高、地径、材积、新生长和冠幅等生长性状和纤维长、宽、长宽比、基本密度和纤维素含量等材性指标的差异达显著或极显著水平，通过综合指数法和PCA分析，初步选出适合黑龙江省营造山杨纸浆林的7个最佳种源。
One hundred and seventy one of materials of 15 provenance were collected in the main distribution (P. Davidiana Dode) and data of provenance testing in Yingchun Forest Bureau of Heilongjiang Province were analyzed in growth and wood quality. The results indicate that there are significant lever (0. 5 - 1. 0) different between the provenance in height, diameter, volume,shoot and crown diameter and fiber length, fiber width, ratio of length to width. By means of the deviation analysis and comprehensive index analysis, 7 provenances (such as Jiangshanjiao,Yongxing etc.) are superior in the growth and wood properties.
