本文就我国引种柚木的历史和效果作一回顾,并与世界各地的柚木生长进行比较。最后评价了柚木在我国的发展前景和提出了柚木引种地带的区划。我国从十九世纪初期开始引种柚木,1960年以后才大量发展。柚木种源来自缅甸、泰国、印度、老挝、越南、印度尼西亚和马来西亚。现已引至南方7个省(区)45个以上的县(市);最北界已达福州(26°05′)和四川的渡口(26°35′)。柚木成年大树可越冬,但生长已受低温制约。台湾与海南岛是我国栽培柚木最多的地方。海南岛10—20年生柚木树高年平均生长量为0.5—1.5m,胸径0.6—1.7cm,接近原产地水平。
This paper reviews the history and effects of introduction of teak in China and compares it with the growth of teak all over the world. Finally, the development prospects of teak in our country were evaluated and the zonation of teak introduction zone was put forward. Since the beginning of the nineteenth century, China began to introduce teak wood, which was not developed until 1960. Teak provenance comes from Myanmar, Thailand, India, Laos, Vietnam, Indonesia and Malaysia. It has been introduced to more than 45 counties (cities) in seven southern provinces (districts); the northernmost border reaches Fuzhou (26 ° 05 ’) and Sichuan (26 ° 35’). Teak adult trees can wintering, but the growth has been constrained by low temperature. Taiwan and Hainan Island are the most cultivated teak in our country. Hainan 10-20 year-old teak high average annual growth of 0.5-1.5m, diameter 0.6-1.7cm, close to the level of origin.
