摘要
选取伊春林科院实验站内落叶松试验林6个树种,对其生长和纸浆材材性进行分析。结果表明,各树种的树高、胸径、材积、基本密度、纸浆得率、综纤维素含量、木素含量、纤维长度、纤维宽度等指标差异均达到了显著或极显著水平。通过综合坐标法,选出黑龙江省伊春地区生长和纸浆材材性兼优的落叶松树种。
This article investigated the growth characteristics and pulpwood quality of 6 species in the larch experimental forest at Yichun academy of forestry experimental station. The results showed that the average tree-height, diameter at breast height （DBH）, timber volume, basic density, pulp yield. Holocellulose content, lignin content, fiber length and fiber width of 6 species are significant（ P 〈 0. 05） and extremely significant（ P 〈0. 01 ）difference. L. olgensis was the best pulpwood species in Yichun of Heilongjiang.Province by comprehensive evalution.
