| 摘 要： | 对不同树龄黑荆树间伐材、枝丫材〈大头直径≤４ｃｍ 〉生物量和单宁含量测定的基础上，研究试材不经剥皮、直接削片提炼栲胶的可能性． 试验结果表明， 黑荆枝丫材在适宜的工艺条件下提炼的栲胶质量达ＧＢ２ ６１７—８１ 一级木麻黄栲胶指标值， 达ＦＤＢ／ＬＹ１ ８７９－ ８７ 二级黑荆树栲胶指标值． 产品具有优良的鞣革性能， 原料成本仅为一级木麻黄栲胶原料的４１％ ～５７％ ，不失为栲胶生产的好原料． 而黑荆间伐材不宜单独作栲胶生产原料

| Abstract: | Based on the analysis of the biomass and tannin contents of Acacia mearnsii Willd thinned wood and branches(butt end diameter≤4cm) with different stand ages,this paper systematically studied possibility of selecting tannin extract from the samples of unbarked and direct chipped branches and the thinned wood of Acacia mearnsii Willd.The results showed that the product quality could meet China National Standard (GB2 617 81AND) and Fujian Local Standard (FDB/LY1879 87) with suitable technical parameter.The product has good tanning properties and the cost of its raw material is only 41%～57% of asuarina bark's. |
