桉树优良无性系制浆造纸性能与适应性的研究

对福建漳州岩溪、天马和南靖3个试验点桉树品系的抗风抗冻、纤维材生长性状、木材纤维形态和化学组成成分等性能的测定与分析,经多性状综合评判、交互效应与变异分析,从中选择出具有抗逆性强、纸浆性能好、较高生长量、生物量和纤维产量,适合闽南山地发展的C9、C10和C6等3个桉树优良品系 这3个无性系4年生年平均树高和胸径生长量、每株干·a-1和4 2～7 5kg·材重量和纤维产量分别可达3 7～4 4m、3 3～3 7cm、9 2～16 1kg·株-1株\+-1·a-1,且抗逆性强、稳定性好、木材纤维形态和化学组成等良好特性,是制浆造纸优质原料

Study on Adaptability and Function of Eucalyptus Fine Clone for Paper Pulp Timber

The measurement and variance analysis were conducted on resisting storm and freezing calamity, growth character, wood fiber form, chemical composition etc. of Eucalyptus clones in Yanxi, Tianma and Nanjing experimental plot of Fujian province. By comprehensively evaluation each other effect and variance analysis on clones,three Eucalyptus clones(C6,C9,C10) were selected which have character of strong resistance, good paper pulp function, high growth, biomass and high fiber weight and fit for growing on hilly land of southern Fujian. In those three clones, the average annual growth of height , DBH, log weight , fiber production per tree were 3.7～4.4 m , 3.3～3.7 cm, 9.2～16.1 kg株~(-1)a~(-1), 4.2～7.5 kg株~(-1)a~(-1) at 4 years old, and they have good character of strong resistance, good stability and good wood-fiber form and chemical composition.So,there are excellent material for making paper.
