摘要
本文以福建省顺昌县三种立地条件下的 2 4年生杉木人工林木材为对象 ,首次分别建立了三种立地条件下以及不考虑立地条件下杉木人工林木材密度与纤维长度随生长因子中的生长轮年龄和年轮宽度的一系列回归模型 ,并进行回归显著性检验 ,为杉木人工林木材材质的早期预测和定向培育提供科学的理论依据。
In this study,the Chinese fir wood from plantation with 24 ages grown in three different sites from Shunchang county of Fnjian province were settled as material.The wood density and the fiber length varied with the cambium age and ring width were firstly quantitatively modeled in three different sites or any sites.Meanwhile,remarkable test on these regressive equations were carried out.The conclusions provided a scientific basis for early forecast and directive culture about wood quality of Chinese fir from plantation.
