楸树心材与边材的生长特征及变异规律
|
摘要
为系统了解珍贵阔叶树楸树心材与边材的生长特征及边心材转化规律,采用树木年轮分析仪对5株楸树不同树高处的圆盘进行年轮数、宽度等生长特征测定,建立心材与树木各生长量之间的回归模型。结果表明:楸树年轮宽度在10～15年达到峰值,可持续10年左右;心材起始树龄为5.26a,心材形成速率为0.90轮/a;属于生长收获周期短、心材形成时期较早且形成速率较快的树种。
To better understand growth characteristics of heartwood and sapwood and variation in heartwood formation of Catalpa bungei,a series of experiments were conducted to measure ring number,and widths of heartwood and sapwood at different tree heights by using tree-ring measuring station.A regression model of relationship between heartwood and tree growth was established.The results showed that annual ring widths of the trees reached peak at the 10th～15th year and could maintain the peak in 10 years.The heartwood started to form at age 5.26 a,and the heartwood growth rate was 0.90 rounds/a.It was concluded that Catalpa bungei is a hardwood species with a short growing and harvesting period,an early heartwood forming period and a fast growing rate.
