Are there fast growing eucalyptus trees in Japan? What are the hazards?

Fast-growing eucalyptus. Fast-growing eucalyptus.

Aliases: White Diesel Tree (Chaoshan), Mangshu (South Australia), Yougali, Eucalyptus Big-leaved (Puning), Eucalyptus Big-leaved, Oil Galli, Garry Tree, Eucalyptus Big-leaved (Huiqi Ziyang).

Fast-growing eucalyptus refers to the hybrids of Eucalyptus macrophylla*Caudal Eucalyptus, Eucalyptus macrophylla*Red Eucalyptus, Eucalyptus willowifolia*Eucalyptus longensis and Eucalyptus caudal*Eucalyptus microphylla, etc., with many strains, named after the series code. The characteristics of each strain are different: the one that grows fast rolls up to 10 meters a year; cold-resistant ones are more resistant to two degrees of low temperature than the original species; There are also disease-resistant.

There are two main ways of seedling propagation: tissue culture and cuttings, and it is necessary to regularly select superior plants as seed sources. If the site conditions are good, it can be harvested for five years, and the yield per mu is eight cubic meters of woodThe rate of economic return (economic maturity) is more than 20% years.

The wood is mainly made of plywood, and the secondary wood is used to make high-grade coated paper or copy paper.

1.Natural forests are destroyed. Forest land is needed to create fast-growing forests.

2.The single tree species causes simple plant communities, destroys the ecology, and causes serious soil erosion. The growth cycle of fast-growing forest is very short, and because it is developed as a cash forest crop, it is often unable to form the ecological chain that the mountain forest should have in the area where it is planted, and the vegetation is single, which causes great damage to the living environment of wild animals, birds and insects.

3.Those who demand more than return soil fertility have experienced destruction.

4。Excessive use of chemical fertilizers, poisoning the soil.

5.Invasive alien species, most of the fast-growing forest species introduced in the south are alien species, such as eucalyptus, which has strong vitality and is difficult to break roots, which threatens native species and changes the entire natural ecological balance. Native trees in fast-growing forests are difficult to survive and other crops cannot be grown.

6.Fast-growing forests usually have the ability to absorb water and fertilizer, which often makes the plants around the fast-growing forest unable to survive, and destroys the diversity of vegetation searched by the first party. At the same time, because of his domineering ability to absorb water, people who are familiar with this plant usually give him the title "pump".

In areas where "pumping" is planted, after many years, it is often found that the soil is loose and desertified. Often, in the cols with dense vegetation, we can find springs and streams. However, where fast-growing forests grow, it is difficult to find springs and streams in even the densest areas due to frequent logging.

7.The income period is short, and the first three rounds of planting generally have better economic benefits, but even if a large amount of chemical fertilizer is used in the future, it is difficult to have better forest income.

Fast-growing eucalyptus is a tree that has a significant negative impact on the environment.

One. Due to the rapid growth and high water consumption of young eucalyptus plantations, the regulated flow rate is poor.

Two. Eucalyptus is not an excellent tree species for controlling soil erosion.

Three. Eucalyptus natural forests can control soil leaching and surface flow, while eucalyptus plantations can form humus and prevent soil degradation, but they are not as effective as local broad-leaved tree species.

Four. In eucalyptus plantations with short rotation periods, if the entire biomass is removed during the felling period, the nutrients stored in the soil will be quickly depleted.

Five. Eucalyptus produces intense competition with the vegetation on its surface, because it has a well-developed root system and more branches and leaves, in dry and poor soil conditions, there is little vegetation, on the contrary, in moist soil fertile conditions, competition decreases sharply and vegetation increases.

Sometimes, it is difficult to strike a balance between the economy and the environment. At present, in many places, paying attention to the economy and developing the economy is the last word. We must take a long-term view and take the path of sustainable development, after all, we have a future.

Personal opinion, no harm.

Many people are saying that there is no grass under the eucalyptus tree, there are no birds flying on the eucalyptus tree, and even the caterpillars do not eat the leaves of the eucalyptus tree!

I don't know if anyone who said these things had ever seen eucalyptus, or for what purpose, but I do know that the state does not prohibit the cultivation of eucalyptus, but encourages the rational and long-term development of the eucalyptus industry.

If eucalyptus is poisonous, why can eucalyptus leaves be used as food for koalas koalas? Why can it be used to refine eucalyptus oil as a flavor additive to produce perfumes, cooling oils, cough drops, and carminative oils?

If eucalyptus trees are poisonous, then why can shade-loving crops such as watermelon, pineapple, ginger and other shade-loving crops be grown under eucalyptus forests?

There are fewer birds in eucalyptus forests because eucalyptus trees are healthier and have fewer insects, and there is no food, so there are naturally fewer birds.

Eucalyptus forests can be used for beekeeping and honey production.

Eucalyptus roots can burn charcoal.

Someone's one amazes me!! I don't know if Sufeng eucalyptus is poisonous, but a few years ago, I said that it was poisoned to make glutinous rice with those maple leaves next to the Sufeng eucalyptus tree, and it was on the news. And there is really no grass under those eucalyptus trees!

The grass next to it is also sparse! After chopping, the old water bubbled. The landlord will know if he has planted it.

It is not recommended to plant.
