柚木(Tectona grandis L.f.)国际上誉为重要的热带用材树种之一。原产东南亚,分布印度、缅甸、泰国、老挝等国家。其地理位置南界位于北纬9°(印度),北界位于北纬25°36′。引种区有四大洲51个国家,并已普遍栽培。我国云南南部、台湾南部有大面积栽培,广东、广西、福建也有引种。海南岛引种的3000多亩已成林。我国柚木栽培区与柚木原产地气候上不同特点是气温、水分和风的差异。为了进一步弄清缅甸种源在我国对生态条件适应性的反映,从中找出规律,为柚木速生丰产、良种培育、扩大试种提供数据,从1975年以来,我所对柚木多年生长及年生长周期和物候变化进行了定位、半定位研究。本文仅从柚木年生长规律与温度,水分关系方面加以论述。
Teak (Tectona grandis L.f.) internationally known as one of the important species of tropical timber. Originated in Southeast Asia, India, Myanmar, Thailand, Laos and other countries. Its geographical location is located at 9 ° N (India) in the southern boundary and 25 ° 36 ’north at the northern boundary. The introduction zone has 51 countries on four continents and has been widely cultivated. China’s southern Yunnan, southern Taiwan have large-scale cultivation, Guangdong, Guangxi, Fujian also introduced. Hainan Island introduced more than 3000 acres have become forest. China’s teak and teak cultivation area of origin climate is different from the characteristics of temperature, water and wind differences. In order to further clarify the reflection of the provenance of Burmese on the adaptability of ecological conditions in our country, we can find out the law and provide the data for the fast growing and yielding of teak, cultivating and expanding the trial of teak. Since 1975, I have studied the growth and annual growth of teak Periodic and phenological changes were located and semi-localized studies. This article only from teak annual growth law and temperature, moisture to be discussed.
