香港植林樹種中桉屬樹木是佔有很大的數量,它們快高長大,樹幹畢直,適應環境能力強,是選擇原因.今次介紹的大葉桉在大陸廣泛種植,它是紙漿的原材料,約十年便可以採用.葉片散發的桉油精有消毒淨化空氣的好處.
那麼缺點呢?它快高長大的優點伴著的是容易折斷的缺點,而且斷位很快出現腐爛.大葉桉是白蟻喜愛的樹木.它葉片跌在泥土會釋出物質污染泥土,讓其他植物較難生長.
此樹木在香港已種有多年,壞處不難觀察.
In Hong Kong,
Eucalyptus accounts for a substantial quantity amongst the different
afforesting species. They grow fast with a straight trunk. Their
ability to adapt to environment is strong and it is the reason of
being selected. They have also been widely grown in China. Their
wood pulp is the raw materials for making paper. They can be used
when they』re grown for just about ten years. Their leaves transpire
Eucalyptol which is good for air disinfection and purification.
Then, how about their shortcomings? Accompanying
with their rapid growth, they are prone to easy breakage and the
broken bits soon rot. They are the favorite tree species of
termites. Their leaves, fall onto the soil, release some substances
which contaminate the soil and make it difficult to grow other
plants.
This tree species has been planted in Hong Kong
for many years. Its shortcomings are not difficult to see. |
