海南椴生态生物学特性初步研究

A PRELIMINARY STUDY OF ECOIOGICAL AND BIOIOGICAL CHARACTERISTICS OF HAINANIA TRICHOSPERMA

海南椴是我国特有珍贵树种，广西第一批保护植物，仅分布在海南和广西南部局部地区；热带性树种，喜光耐旱，对土壤适应性强。引种试验表明，能耐－６℃低温，种子场圃发芽率８０％以上。实生苗六年生便开花结果。

Hainania trichosperma is an endemic species from China and including in the List of Rare and Endangered Plants. It distributes in Hainan and Guangxi. It is a tropical plant, light-demanding and drought resistant, adapts to limestone soil and acid soil.
