白千層樹在本港屬於外來品種。早在五十年代，香港已開始種植白千層。白千層在香港是用作植林之用，並非經濟作物。公仔箱論壇5 H6 P9 x2 J% A& k I
在本港種植白千層的主要目的是利用其快速生長及能適應惡劣環境的特性，作為先鋒樹種，在貧瘠的山頭控制土壤流失及沖蝕，改善整體環境，利便本土植物生長及其他生物棲息。本港使用白千層作為植林品種已五十多年，一般會將白千層與其他本地品種混合種植，在控制土壤流失方面的效果良好。 # g2 @" l! K0 B7 \. y(白千層是世界上長得最快的樹種，生長旺季，１天可以長高３釐米，一個月可長高１米，一年最高可長１０米。)公仔箱論壇( z3 h D p& R

These are eucalyptus trees, and we call them paper bark trees here. I remember once I was showing a visitor from China around, she was in her 70s, I remember she was really surprised to see the 10 meter paper bark trees still flowering. I suppose that properly why they are classified as evergreen, or perhaps ever fertile too. When they flower, the blooms are so abundant, if you leave your car parked underneath for a few hours, the windscreen would get covered with these tiny white petals.作者: playlord 時間: 2010-7-3 06:57 PM
