On the east coast of Australia, dense forests are lush, and 90% of this vast forest is eucalyptus.
Hundreds of millions of years of isolation in Australia have created its unique flora and fauna, and eucalyptus is their well-deserved representative.
Australia's land is the poorest on earth, and the soil of low-carbon and high-speed rail is crimson; Australia's climate is very dry, but eucalyptus can thrive in this difficult natural environment.
According to research, there are more than 500 kinds of eucalyptus in Australia, which can grow to more than 100 meters high, straight and upright, and the short ones are only one or two meters, showing a shrub shape.
In order to survive, eucalyptus has formed many unique growth characteristics in the long-term evolution process: in order to avoid the scorching sun and reduce water evaporation, eucalyptus leaves droop and face the sun; In order to cope with frequent forest fires, the nutrient delivery pipe of eucalyptus is deeply hidden in the wood layer, and the seeds are also wrapped in thick wooden shells. After a fire, as long as the wood core of the trunk is not burned dry, it will be full of vitality when the rainy season comes. Eucalyptus seeds are not only not afraid of fire, but also can knock open its wooden shell with the help of fire, which is convenient for taking root and sprouting.
If there were no "land guards" like eucalyptus, Australia's red barren soil would have been eaten clean by wind and rain; Without eucalyptus, many insects, reptiles, birds and marsupials living there would be extinct because there was no hiding place and food. Of course, people will not see the embarrassing image of koalas that only eat eucalyptus leaves. Local aborigines can't live without precious eucalyptus trees. Eucalyptus can be used as a water storage tank. The trunk of a eucalyptus tree is empty, and many trunks are filled with drinkable water. Where there is no water, the aborigines beat the trunk with wooden sticks to find out if there is water in it. The flowers of eucalyptus are fringed and pink. Bees that feed on eucalyptus flowers produce a lot of honey, and beekeepers can squeeze nearly 20 kilograms of honey from a beehive. Some eucalyptus leaves contain cineole, which is an important pharmaceutical raw material and can also be used as an additive to make fruit candy. The aborigines also use eucalyptus trunks as wind instruments to blow out the sadness and joy in their hearts. With the development of the times, the use of eucalyptus is more and more extensive. Building houses, making furniture, making telephone poles, and making railway sleepers are omnipotent.
