象牙树学名Diospyros ferrea),常綠小喬木, 株高可達5~6公尺,为柿科柿属下的一个种。象牙樹曾是臺灣特有種,但約於1870年時由人工栽植於東南亞,現分布於臺灣印度琉球馬來西亞四個地區。

生長環境

[编辑]

象牙樹大多生長在沿海地區,可忍受鹽質土壤,耐強風、乾旱,可用作防風林,喜好年均溫約21~25℃。

用途

[编辑]

象牙樹木材呈黑色,生長緩慢,堅重致密,磨之有光澤,用途和烏木類似,為珍貴的木材之一,可作小用具、手杖等。木材深埋地下日久,漸起化石作用,質地更加堅重,顏色也更暗,即“陰沉木”的一種,是庭園美化、盆景之優良樹種。

繁殖

[编辑]

繁殖以扦插和播種爲主,扦插法用技插或芽葉插,極易生根,一年四季均可扦插。冬季扞插溫度需保持在10℃以上,約1~2個月可生根;夏季扦插則僅需2~3周。
