宜宾油樟人工林生长特性

Research on Growth Characteristics of Cinnamomum longepaniculatum Plantation in Yibin County

  • 摘要: 采用树干解析法对27 a生宜宾油樟人工林生长规律进行研究。结果表明:27a生宜宾油樟的树高、胸径与材积总生长量分别为14.6 m、17.00 cm和0.141722 m3;宜宾油樟树高年平均生长量在12 a生时达到最大值,树高数量成熟龄约为13 a。其胸径生长培育关键期是在生长期的前18 a;材积的连年生长量在18a生时达到最大值为0.009631 m3,材积的数量成熟龄约28 a。材积生长过程可分为3个阶段:1 a~9 a生长缓慢期,9 a~18 a生长快速期,18 a后生长减缓期。

     

    Abstract: The research was conducted on forest growth characteristics of Cinnamomum longepaniculatum planted in Yibin county by stem analysis method. The results showed that tree height, DBH and total volume increment of the 27 year old Cinnamomum longepaniculatum were 14.6 m, 17.0 cm and 0.141 722 m3, respectively. The annual increment of tree height reached the maximum at the age of 12, and its quantitative maturity age was about 13. Its critical growth period of DBH was in the first 18 years during plant growth. The current annual increment of volume reached the maximum (0.009 631 m3) at the age of 12, and its quantitative maturity age was about 28. The growth process of volume could be divided into three stages:1 year~9 years being slow growth phase, 9 years~18 years being fast-growing stage, and being progressive decelerational phase after 18 years.
