红椿天然林木材解剖性质研究
|
摘要
为了给四川红椿的材性选育提供依据,采用生长锥钻取木芯的方法,对红椿天然林木材解剖性质进行了研究。结果表明:攀西地区红椿天然林木材平均纤维长度、宽度、双壁厚、腔径分别为1 118.1、17.2、7.0、14.4μm,平均导管长度、宽度、壁厚、腔径分别为297.4、205.7、9.8、175.4μm。随着树龄的增加,不同单株木材纤维及导管各指标均呈上下不规则波动且整体略微增加的趋势;不同地区间木材解剖性质各指标除导管腔径没有显著差异外,其余各指标均有显著差异。德昌县木材导管腔径和纤维腔径大,可作为装饰用材和改性用材的重点育种材料;盐边县木材纤维长度及双壁厚大、力学强度好,可作为家具用材的重点育种材料;米易县红椿木材导管腔径较大,也可作为改性用材的育种材料。
The wood anatomical structure of natural Toona ciliate Roem. forest in Sichuan province were studied by using growth cone for wood core in order to provide basis for timber material selection. The results show that the average fiber length, width, double wall thickness and cavity diameter of Toona ciliate Roem. were 1118.1 μm, 17.2 μm, 7.0 μm and 14.4 μm, respectively. While the average catheter length, width, wall thickness and cavity diameter were 297.45 μm, 205.69 μm, 9.81 μm and 175.43 μm, respectively. The size of indexes of fiber and catheter of single plant fluctuated irregularly and slightly increased as a whole with the increase of tree age.There was significant difference in the index of wood anatomical structure among different areas except the catheter cavity diameter. The Toona ciliate Roem. wood from Dechang county can be used as important breeding materials for decorative and modified timber with large cavity diameter of catheter and fiber. And the wood from Yanbian county can be used as important breeding material for furniture timber with large fiber length and double wall thickness and good mechanical strength, while the wood from Miyi county can be used as breeding materials for modified timber with large catheter cavity diameter.
