马褂木的习性、分布与造林初探

马挂木(Liriodendron chinesis)是我国亚热带地区重要的造林绿化树种之一,过去对该树种的研究甚少。根据笔者的调查试验资料及各地报告的汇集,本文从营林角度对马褂木的地理分布、生长习性、生态要求和造林等进行综合介绍,目的为深化马褂木的阐述并开拓今后的研究思路。

A PRIMARY STUDY ON CHINESE TULIP TREE AND ITS YOUNG PLANTATION IN CHINA

Liriodendron has only two species, yellow-poplar in the United States, Chinese tulip tree in China. The original of Chinese tulip tree is a second-class national protection species in our country. It distributes naturally in the south-central of the Chinese subtropical zone. There are three distribution areas and the main production one is in Xiang-E-Qian region. This paper is dealing with its ecological environment, biological characteristics, growth and development. A primary study on its young plantation's growth, biomass and thinning period has been made.Chinese tulip tree grows fast. Its timber has many uses, especially in the production of plywood and pulp. It is also a fine ornamental tree and should be planted more in the future.
