摘　　要：无论是从林业角度还是在制浆性能方面，不同种源间存在明显差异。本文研究了我国亚热带地区引种澳大利亚相思树的基本密度、纸浆产率、制硫酸盐浆和漂白性能，比较了不同种源间的差异。研究结果表明，在有效碱用量为１２．５％～１５．５％时纸浆得率达５１．２％～５３．６％，经ＣＥＨＤ四段漂白后，所得纸浆性能可以满足配抄印刷和包装类用纸要求。综合考虑并结合生长性能，福建南乎地区黑荆树最佳种源应为１４９２２和１４９２５，漳州地区最佳纸浆材种源为６８７８和１４２２９。Wood and its pulping properties can be affected obviously by difference of provenances of trees. Kraft pulping and bleaching (by a CEHD sequence)experiments on Acacia spp. grown in Nanping and Zhangzhou,both in substropical area of China,and introduced from different parts of Australia are reported.Basic density,pulp pro-ductivity,kraft pulping and bleaching of nine species were tested.By kraft pulping with active alkali levels ranging from 12.5%to 15.5%,the pulp yield was from 51.2%to 53.6% After CEHD bleaching,all pulps obtained are adequate for printing and pack-ing furnishes. It was concluded in combination with forestry studies that Acacia mearn-sii 14922 and 14925,each from NW of Braidwood,NSW and Blackhill Reserve,Vic.,Australia are the best provenances for Nanping area,A. parramattensis(6878 from Gorse R Blue MTNS,NSW)and A.trachyphloia(14229 from Monga State Forest,NSW)are best for pulpwood plantations in Zhangzhou area.
