摘要：濒危植物翠柏为柏科高大珍贵用材树种,通过对翠柏主要分布区墨江、昌宁翠柏植株树干解析,研究了两地翠柏的生长特性,结果表明:(1)翠柏在20年前生长缓慢,20—60年进入快速生长期,70年以后达到数量成熟,材积生长量开始下降并趋于稳定;(2)翠柏幼苗期具有耐荫性和长大后有喜光特性,墨江地区翠柏生长好于昌宁地区,其生长表现与两地自然条件相符合;(3)针对翠柏特点,提出幼苗时搭建荫棚,幼树时期进行疏伐,数量成熟时期进行间伐或疏伐等促进生长经营措施,为翠柏资源培育与保护奠定基础。
Calocedrus macrolepis is a precious timber species in China. The method of stem analysis was used to compare the growth characteristics of C. macrolepis in Mojiang and Changning of Yunnan Province, which are the main distribution of C. macrolepis. The results indicated that： （ 1 ） The growth rate was slow in the initial 20 years, and the stand reached quantitative maturity at 70a when the volume increment began to decrease and tend to be stable. （2） C. macrolepis are shade tolerance and heliophilic. The growth vigor of C. macrolepis in Mojiang was better than that in Changning, which was consistent with environmental conditions. （3） According to its growth characteristics, some management measure were put forward including putting up shed in seedling stage, release cutting in sapling stage, thinning in mature age, etc.
