黄梁木又名团花(AnthocephalnsChinlnsis)是一个生长快、成材量大的热带速生造林树种,在国外被誉为“奇迹之树”,“宝石之树”。为了掌握黄梁木的生长规律和利用价值及其发展前途,我们曾经深入我国黄梁木产区的广西十万大山和云南省西双版纳进行调查。现将调查结果,简报如下: 1.生长快天然生长:在云南省西双版纳地区,仅14年生的黄梁木,树高达26米,胸径59厘米(平均每年长4.2厘米),单株材积3.3立方米以上。在广西龙州,4年生,树高达9.8米,胸径
Anthocephalns Chinlnsis is a fast-growing, large-scale tropical fast-growing afforestation species, known as “the tree of miracles”, “tree of precious stones” abroad. In order to grasp the growth law, utilization value and development prospects of Huangliangmu, we have conducted an investigation into Guangxi Shilan Mountain in Huangliangu producing area and Xishuangbanna in Yunnan Province. The results of the survey are summarized as follows: 1. Growing fast Natural growth: Only 14-year-old yellow-beam wood in Xishuangbanna Prefecture of Yunnan Province has a tree height of 26 meters and a diameter of 59 centimeters (average length of 4.2 cm) per year. The volume per plant is 3.3 cubic meters the above. In Longzhou, Guangxi, 4-year-old tree up to 9.8 meters, diameter at breast height
