摘要
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。
In order to selecte the proper poplar varieties for paper-making wood 14 fast growth poplar varieties that are widely cultivated in Shan dong province have been tested.Different variances including volume growth,fiber shape and chemical composition are analyzed.The results show that:The average fibre length and fibre content of 14 poplar varieties in 6-year-old stand is 0.863-1.051mm and 51.37%-58.17% respectively.All the varieties except P.×eur`sacrau-79',P.×eur`I-214'and P.×eur.`I-45'conform to the pulp-making standard.Taking both the growth and fibre characteristics into comsideration,poplar varieties of P.×eur.`Zhong Lin 46',P.×eur.`Zhong Lin 23',P.detoides`Lux'and P.×eur.`Zhong Lin 28'are highly recommended for pulp making.P.×eur,`San Martino',P.×eur.`ZhongLin 14',P.×eur.`ZhongLin 45',P.×eur.`Luisa Avanzo'and P.×eur.`cima'are also suitable for it.
