From "making money" to "being cleaned up", should eucalyptus be banned? What is the harm of eucalyptus?

The so-called "relying on mountains to eat, relying on water to eat", Guangxi is a typical area with less land and more mountains. If we want to develop Guangxi well, we must make a fuss about the mountains.

In this case, Guangxi has found a way to "plant eucalyptus".

From the end of last century to the beginning of this century, in a short period of more than ten years, the planting area of eucalyptus in Guangxi has increased at the rate of 2 million mu per year, which has rapidly increased by more than 10 from the beginning to the present, with a total area of 32 million mu.

Today, the eucalyptus planting area in Guangxi accounts for half of the country's total area.

There is even a famous saying that "the world eucalyptus sees Brazil and China eucalyptus sees Guangxi".

I thought I had found a way to develop, but I didn't expect the eucalyptus trees in Guangxi to be devastated in recent years.

This year, the spring in Guangxi came very early. Spring has come, not spring ploughing, but it has ushered in the "Eucalyptus Cleaning Action".

Eucalyptus is thicker and taller, so cut it when you say it.

Even the saplings planted in Lian Gang that haven't grown into big trees have been uprooted.

Eucalyptus planting was advocated two years ago. Why should it be cleaned up now?

Planting eucalyptus in Guangxi has natural geographical and climatic advantages.

Since it was introduced to Guangxi, it has grown faster than other trees planted in Guangxi. Eucalyptus has excellent materials and wide uses. After decades of breeding and improvement, it has become the most popular tree in Guangxi.

However, Eucalyptus, as an exotic variety, was widely discussed when it was introduced. Some people think that it can bring benefits to Guangxi and can be planted. Some people think that it is a "poisonous tree" and should not be introduced. Discussions never stop.

The introduction of eucalyptus planting was originally a good thing for Yimin, but the interests of villagers were damaged because local tyrants invaded forest land under the banner of planting trees.

Later, rumors about eucalyptus emerged one after another, from the earliest "rich tree" and "rich tree" to today's "water pump" and "seedless tree", all of which were placed on eucalyptus.

Of course, the reason why a variety show will be cleaned up in a large area is not only because of these external word-of-mouth reasons, but also because of its fundamental reasons.

1, eucalyptus source

Eucalyptus comes from Australia and its surrounding islands.

Since19th century, countries have introduced eucalyptus planting.

More than 120 countries introduced eucalyptus, with a planting area of over 200 million mu.

Eucalyptus has been introduced to China from 1890 for a long time. In the past 100 years, eucalyptus planting has not had any negative problems, nor has it caused any adverse ecological impact.

2. Why do you want to clean eucalyptus?

What is the problem of eucalyptus planting? Eucalyptus is planted for the purpose of obtaining wood, so it should be planted in woodland, but some people are driven by interests and begin to ignore it.

Cultivated land was destroyed, eucalyptus was planted, and what's more, it was planted in farmland.

Improper planting measures and poor management of managers lead to short rotation period, single species, low biodiversity and abuse of chemical fertilizers and pesticides, which leads to soil erosion and water quality destruction.

All these consequences are actually caused by improper artificial planting.

Therefore, the large-scale "Eucalyptus Clean-up Action" we are seeing now actually cleans up illegally planted Eucalyptus, not Eucalyptus in woodland.

3. Change the development mode of eucalyptus.

The controversy about eucalyptus is still going on, but in any case, we should realize that Guangxi has now formed a complete eucalyptus industrial system.

The annual output value of Guangxi eucalyptus industry chain exceeds 400 billion yuan. The beneficiaries of this industrial chain are not only businessmen, but also farmers and workers, including taxes.

So in any case, the industrial chain of eucalyptus planting cannot be broken.

The fact that eucalyptus is the industrial pillar of Guilin, Guangxi will not change until better trees are found to replace it and ensure the national wood supply.

In this case, how to change the development mode of eucalyptus has become a top priority.

First of all, we should reasonably control the eucalyptus planting area and the total scale, and control the eucalyptus planting area within 12% of the total forest area.

At the same time, the yield per unit face value can be improved by formula fertilization and seedling improvement.

Simply put, it is to plant more trees with less land.

Secondly, we should strictly follow the laws of nature and choose suitable areas to plant trees.

It is forbidden to plant eucalyptus in water sources, cultivated land, nature reserves and other places.

Reduce the phenomenon of pure eucalyptus planting, replant broad-leaved forest after thinning, gradually transform a single pure eucalyptus forest into a mixed forest, and advocate natural management.

Avoid burning mountains and keep the original vegetation in the mountains.

Third, use herbicides and other pesticides carefully, use pesticides safely, use organic fertilizers and slow-release fertilizers to reduce mountain pollution.

Only in this way can we ensure the planting of eucalyptus and maintain the original ecological environment.

Guangxi's "Eucalyptus Cleaning Action" is intended to clean up, and its purpose is to standardize the land order.

Only in this way can it be more conducive to the future development of eucalyptus.

Nowadays, it is no longer feasible to blindly expand the planting area, but it is fundamental to increase the yield per unit area.
