闽南山地桉树纤维材优良无性系的选择研究

STUDY ON SELECTION OF EUCALYPTUS FINE CLONE FOR FIBER TIMBER IN SOUTHERN HILLY LAND OF FUJIAN

对福建漳州岩溪、天马 2个试验点 1 3个桉树纤维材无性系的生长性状、木材纤维形态和化学组分等性能进行测定与分析 ,并经多性状综合评判 ,选择出具有较高的生长量、生物量和纤维产量 ,适合闽南山地发展的C9、C1 0、EC1、EC3、C6共 5个纤维材优良无性系 ,其中尤以C9、C1 0、EC1三个无性系的各性状为最优。这 5个无性系 ,3a生年平均树高和胸径生长量、每株干材重量和纤维产量分别可达 3 93～ 6 60m、3 83～ 4 97cm ,9 71～ 2 0 48kg·a- 1 和 4 3 6～ 9 5 2kg·a- 1 ,而且木材纤维形态和化学组成等特性良好 ,可进一步扩大繁殖、推广应用。

The measurement and analysis were conducted on growth character, wood fiber form, chemical composition etc. on 13 eucalyptus clones in Yanxi and Tianma experimental point,Fujian Province. Through comprehensively evaluation on clones,the selected clones with attributes of fast-growing, higher biomass and fiber weight included C9、C10、EC1、EC3、C6, among them C9、C10、EC1 were the best. For these five clones, the average annual growth of height and DBH, and log weight and fiber production per tree were 3.93～6.60*!...
