摘　　要：以贵州和新疆产葵秆为原料 ,对其进行化学分析并试制葵秆层积材 ,试验结果表明 :两种葵秆原料主要化学成分与杨木相当 ,但抽提物含量高 ,酸碱缓冲容量大 ,对胶合有不利影响 ;葵秆层积材静曲强度较高 ,但内结合强度偏低。In this paper,chemical composition,pH value and acid alkali buffer capacity of two kinds of sunflower-stalks from Xinjiang and Guizhou were analyzed,and laminated sunflower-stalk board were developed.The result indicated that chemical composition of two kinds of sunflower stalks was similar to poplar,but extractives and acid alkali buffer capacity were taller,which had some harmful influence on bonding.The MOR of laminated sunflower stalk-board was high,but the IB was low.
