Peeling eucalyptus, but a big head, an adult, it can grow to about 70 meters, equivalent to 20 storeys high. I want to look good, because as it is maintained in an appropriate place. Peeling eucalyptus very cold, often rainy most like to live in the tropics
.
The introduction of history
Stripping is a new species of eucalyptus plantations in comparison, until recently still in the pilot stage or try to grow. First in 1918 and 1926, the growth in Mindanao Cotabato region of native species introduced to other islands in the Philippines, namely northwestern Luzon Baguio. 1954 was first introduced to the island of Cebu. Introduction of the main island of Papua New Guinea for the first time in 1948 also stripped eucalyptus, species from the neighboring island of New Britain carat watts. In addition to Southeast Asia and other countries in the late 1950s or 1960s also carried out small-scale introduction. Such as Ivory Coast and the Solomon Islands in 1958 and the introduction, Congo introduction in 1961, the introduction of Sri Lanka in 1967.
Compared with other species, the total area of cultivated eucalyptus stripping is still small. By 1974, the cultivation area of about 7000 hectares of the Philippines, the Philippine paper industry mainly by the company's culture. To 1973, the cultivated area of Papua New Guinea is 736 hectares, and plans to rapidly accelerate the cultivation of speed. Congo reported cultivated area of 170 hectares, mainly in the period 1961-1966 cultivation. Ivory Coast reported that try to grow 50 hectares peeling eucalyptus, and plans to foster large-scale industrial peeling eucalyptus forest. British Solomon Islands has planned to cultivate 32,000 hectares in 1985. Many other tropical countries have stripped the introduction of eucalyptus trees in the area and the test area.

, where a rainbow eucalyptus origin. As an odd tree, rainbow eucalyptus has also been introduced
in South America
,

and other countries.
Growth habit
Stripping Eucalyptus is
the only naturally grown in the north and south of the equator nuclear tree species
,
suitable for the growth in annual plenty of rain and high uniformity and temperature conditions
, and under these conditions, other species may be infected with the disease. Under these conditions, stripping fast nucleation and growth, and has good dry form. It's very easy to catch fire. It is early flowering and seed, cuttings of young branches root easily, but poor ability to initiation, initiation and therefore can not be used to update the stripping method eucalyptus forest.
The main value
Mainly used for peeling eucalyptus pulpwood. Due to rapid growth, eucalyptus or stripping ideal fuelwood, more than 15-year-old wood, can produce high-quality
charcoal
. In addition, according to further large peeling made for plywood, joinery and construction timber.
Some people may think that one color rich tree, if not become the object of worship, at least for public exhibition in the park and forest. Unfortunately, rainbow eucalyptus did not get this treatment. People around the world planted this tree is mainly due to get
wood
for this purpose. Wood pulp is the most common type of material used for paper, can be extracted from wood by chemical or mechanical means. It is a dry, raw materials rich in fiber, when floating in the water, contained fibers fanned out at the same time become more flexible.
Pulp
is seen as a green resource demand in the past few years has been a growing trend, planting trees for wood pulp to obtain pulp produced only 16% of world production. In addition, about 9% of the original forest, and the remaining 75% from the second generation, the forest is more rearward third generation and era. For that little bit of wood pulp each year a large number of trees tragic waste. At the same time, reforestation and tree planting these efforts devoted to wood pulp production is also increasing, so the trees become a renewable resource in the true sense.
Planted
Many world
multi-tropical countries
are already in the park afforestation experiments and peeling eucalyptus introduction of recording, but overall, peeling eucalyptus plantation area is not large, plantation history is not long. Peeling eucalyptus plantations, mainly in the Philippines,
Solomon Islands
, New Guinea,
Congo
,
Ivory Coast
, Sri Lanka,
Uganda
, more than 10 countries.
In 1948, New Guinea for the first time stripping planting eucalyptus plantation, 1950's and 1960's, some other countries have begun planting introduction.
