山西中南部黄波椤引种的适应性

以4种当地常见森林树种为对照,研究了黄波椤在山西中南部地区的适应性。试验结果表明:黄波椤的树高生长量处于参试树种的中间位置,而树高连年生长量在栽培后期(26 a)达到0.45 m,高于油松、落叶松、辽东栎和白桦4个树种;黄波椤胸径生长量处于参试树种的中间位置,而胸径连年生长量在栽培后期(22 a)达到0.76 cm,高于其他4个参试树种;材积生长量和连年生长量处于5个参试树种的中间位置,黄波椤立木蓄积为24.654 9 m3/hm2,高于油松和辽东栎。因此认为,黄波椤树种可以很好地适应山西中南部的环境气候条件。

Introduction Adaptability of Phelodondrom amurense in the Centric-south Area of Shanxi

We studied the introduction adaptability of Phelodondrom amurense in the centric-south area of Shanxi with four local forest tree species.The height increment of P.amurense in middle of tested tree species, current annual height increment reached 0.45 m (26 a), and bigger than that of the other four tested tree species (Chinese Pine, Larch, Liaodong Oak, and White Birch) .The DBH increment of P.amurense was in middle of tested tree species, current annual DBH increment reached 0.76 cm ( 22 a) , bigger than that of the other four tested tree species.The volume increment and current annual volume increment of P.amurense was in middle of tested tree species with unit area of 1 hm2 , the growing stock volum of P.amurense reached 24.654 9 m3/hm2 , bigger than those of Chinese Pine and Liaodong Oak.Therefore, P.amurense had the ability to adapt the climatic and environmental in the centric-south area of Shanxi.
