摘要
选取不同树干高度的栓皮栎和麻栎木材,分别测定树皮、边材和心材的苯醇抽出物、综纤维素(α-纤纤维素和半纤维素)、木质素(酸不溶和酸溶木质素)、灰分、pH值和缓冲容量,为软木及栎木人造板的生产加工利用提供科学依据。栓皮栎软木生产工艺应关注树皮苯醇抽出物含量、灰分、pH值及缓冲容量;用于人造板加工,则需考虑树种及心边材纤维素、木质素和pH值。
Two species of native Quercus wood(Q.variabilis and Q.acutissima) were selected for evaluating chemical compositions in the bark,sapwood and heartwood,to aim at providing scientific information for making better cork products and wood-based panels.It was suggested that in making cork products,more attention should be given to the changes of bark phenyl alcohol extract content,ash content,pH value and buffer capacity;while in making panel products,it should be taken into consideration the differences of cellulose,lignin and pH value between the two species and between sapwood and heartwood.
