Also known as the Paradise Tree, the Tsubaki tree is native to the northeastern region of the mainland and the Korean Peninsula.
The almond tree prefers fertile, moist soil and thrives in warm, humid climates.
The trunk of the almond tree is straight and thick, with a broad crown and dark green leaves.
In spring and summer, the canopy resembles a giant green umbrella and is beautiful.
Because of this, in the 18th century, the stinky tree was introduced to the United States as an ornamental tree species for landscaping.
United States like to plant ornamental trees to beautify their environment, and the flowers and plants in the front and back yards are always almost the same colorful.
When United States first introduced the almond tree, they liked the ornamental and aesthetic beauty of the tree, and it didn't take long for many places in the United States to be planted with almond trees, and the leaves of the almond trees were lush when spring and summer came, adding a lot of life to the surrounding environment.
The stinky tree invaded the United States.
But it wasn't long before these parts of the United States began to be flooded with skun trees.
After being introduced, the tree had no natural enemies in the new environment, so it was like a wild horse on the United States land, growing bigger and bigger, and even growing the momentum of "swallowing mountains and rivers".
As the tree expands, its seeds are spread to more and more places by more and more birds.
Originally, the introduced almond trees were only planted by the locals in backyards or parks and other places to enjoy it as an ornamental plant, but before they knew it, they were not only limited to the places where humans planted them, but their seeds also spread to the farmland, destroying the growth of crops.
There are even people who use the trees as building materials, but they don't know that the roots of the trees contain a lot of toxic ingredients, so they build the untreated trees into the walls of their houses, causing the people who live in them to suffer physical and mental injuries.
What's more, the expansion of the stink tree is so fast that it occupies the living space of most native plants in the United States.
The growth rate of the stinky tree is extremely fast, not only growing faster, but also taking the sunlight and nutrients needed by other plants to grow on the side, so how can other plants compete with it for living space?
As a result, the mortality rate of native plants has gradually increased, and the stinky tree has gradually become an ecological killer in the United States.
As the flooding of almond trees became more and more serious, the lives and property of residents also suffered more and more losses, and there was even a situation where there was no way to grow food because of the expansion and death of the almond trees, and food became more and more expensive.
This is a disaster that no United States could have imagined.
At first, United States only regarded the stinky tree as a small problem that affected the beauty of the ornament, and no one expected that this small problem would gradually heat up into a very large and widespread problem.
Therefore, the United States want to eliminate all the stinky trees that were first introduced.
In the beginning, United States used physical methods to destroy the stinky tree that was not supposed to live in the United States.
They used a large tree digger to dig up the trees, and they wanted to dig up every stink tree that had been introduced, burn it, and process the roots again.
But this physical method is extremely inefficient, there are countless stinky trees in the land of United States, not to mention that there are many weeds growing between these stinky trees, so large tree diggers cannot dig out roots because of the obstacles of these weeds.
So the United States chose chemical methods and wanted to kill the stinky tree by spraying with chemicals.
The origin of the stinky almond tree.
As a result, the sprayed agent not only did not kill the tree, but was absorbed into the soil by their roots and veins, becoming nutrients for their growth, so that the tree not only was not killed, but also grew more fat.
Faced with such a headache of the problem of stinky trees, the government has long had nothing to do.
After several years of flooding, calm has finally returned.
Ecologists who maintain ecological balance have explored this and found that the flood of almond in the United States is because it is an alien species in Asia, and no natural predator can control the growth of almond, so it is out of control in the United States.
But they also found that China, the origin of the stinky tree tree, has not been overflowing, why is this?
So they compared the environment between China and United States.
It turns out that in China's place of origin, the expansion of the stinky tree is not as serious as that of the United States, because China's agricultural development is slightly later than that of the United States, and the stinky tree has not yet flooded, and Chinese farmers have long used the land for growing the stinky tree.
Because Chinese farmers have long discovered the value of the almond tree, the almond tree can not only prevent wind and fix sand, but also absorb nutrients and harmful substances in the soil while its trees absorb nutrients, purifying the soil, and is a good tree that can be used to protect the environment and prevent wind and sand fixation.
Therefore, the mainland will take advantage of this characteristic of the stinky tree to develop various resources.
The folk of the mainland will also dry the fruit of the stinky tree and make it into food, as a very nutritious food for their own use or sale.
Because the food full of the fruity aroma of the stinky almond is very popular, which makes the farmers on the mainland use the land to protect the ecology at the same time, the economic income is also preserved, which happily solves the problem of the proliferation of the stinky almond tree.
Compared with China's folk, researchers in the mainland have studied the data of the almond tree and found that the allelopathic substances of the alpine tree have a good control effect on pests and diseases, so the researchers in the mainland have conducted an in-depth discussion on this research.
The introduction of the spotted wax cicada.
After discovering the excellent properties of the tree through various studies, the ecological scientists of the United States have finally found a good way to control the tree.
As a plant, the stink tree can also be infested by bugs.
Due to the presence of aphids in the origin of the tree, the tree and the aphid have already established a balanced food chain.
The aphid feeds on the sap of the tree, and at the same time multiplies some viruses in the body, so it mutates into the spotted wax cicada.
This insect is designed to harm the stinky tree, and in severe cases, it can even suck a tree to death.
Ecologists in the United States introduced the spotted wax cicada to the United States to control the flood of the stinky tree.
Over the course of several years, the spotted wax cicada found a suitable environment to thrive on United States soil and began to reproduce rapidly.
Under the damage of the spotted wax cicada, the expansion rate of the tree slowly slowed down, and the flooding was controlled.
This situation gave hope to the United States, so they did their best to cultivate the spotted wax cicada to make the bug reproduce better.
But the good times didn't last long, and after a while, ecologists in the United States found that the number of spotted wax cicadas had decreased dramatically.
It turned out that at the same time as the cicada flourished, the fungus that helped the cicada reproduce also began to multiply rapidly, and even greatly infected the cicada, reducing the number of cicadas to a very low level.
Without the harm of the spotted wax cicada, the tree began to multiply rapidly, and is now a natural predator of other tree species in the Americas.
epilogue
Ecologists continue to introduce various alien species to balance the ecological environment, but this attempt has made the ecological environment of the United States worse.
In order to restore the ecological environment of the United States, United States ecologists are constantly exploring solutions.
With the deepening of ecological research, researchers have also discovered the allelopathic effect of plants, and perhaps the allelopathic effect of plants can bring a little change to the current ecological crisis in United States.
