选择在山东省广泛栽植的 14个杨树品种为研究对象 ,测试了木材的纤维形态、化学成分及林分生长量 ,采用多维空间En多向量理论综合评定法 ,选择纸浆林的适宜品种。研究结果表明 :14个杨树品种 6年生林分木材的平均纤维长度为 0 .863～ 1.0 51mm ,除沙兰杨、I - 2 14杨、I - 4 5杨外均达到中级纤维长度标准 ( 0 .9～ 1.6mm) ;纤维素含量为 51.37%～ 58.17% ,达到了造纸用材的一般标准要求 ;每公顷林分蓄积量可达 191.6m3。综合考虑生长量和纤维性状 ,在选择纸浆材的品种时 ,应首先考虑使用中林 4 6杨、中林 2 3杨、I- 69杨、中林 2 8杨 ;也可使用I - 72杨、中林 14杨、中林 4 5杨、露伊莎杨、西玛杨。
Fourteen poplar cultivars widely planted in Shandong Province were chosen as the research object. The fiber morphology, chemical composition and stand growth of the wood were tested. The multi-dimensional space En multi-vector theory comprehensive assessment method was used to select suitable varieties of pulpwood. The results showed that the mean fiber length of 6 - year - old timber of 14 poplar varieties was 0.863 ~ 1.051 mm, which reached the intermediate fiber length standard except for the Populus tomentosa, I - 2 14 Yang and I - 45 Yang. 9 ~ 1.6mm). The content of cellulose is 51.37% -58.17%, which meets the general standard of papermaking timber. The stock volume per hectare can reach 191.6m3. Taking into account the growth and fiber properties, we should first consider the use of Zhonglin 46, Zhonglin 23, I-69 and Zhonglin 28 Yang when selecting the pulp material. I-72 can also be used , Zhonglin 14 Yang, Zhonglin 45 Yang, Luisisha Yang, Sima Yang.
