Among the various lakes and lakes there is such an aquatic plant, which blooms with beautiful purple flowers, which is pleasing to the eye from afar.
But it is such a beautiful aquatic creature that is the nightmare of many countries, and this aquatic creature is the famous water hyacinth.
Water hyacinth used to be an ecological problem that made it difficult for the United States to spend tens of billions of dollars to cure, and the Americans racked their brains to solve the problem of water hyacinth.
In this way, ecological problems that even Americans struggle to solve have been solved in China in an unexpected way.
This can't help but arouse the curiosity of many netizens, what kind of method does China use to subdue the water hyacinth problem, and what are the reasons behind it?
«——【America's "Green Nightmare"·】——»
Water hyacinth is a magical aquatic creature known for its tenacious vitality and beautiful appearance, and his figure can be found almost all over the world.
In the distant United States, this beautiful creature is like a green nightmare, constantly invading the local waters.
Water hyacinth is a plant native to South America that is known for its amazing fecundity and vitality. The waters of various countries are spreading wantonly, and as long as there are water hyacinths, the ecological environment of the lakes will not be very good.
Water hyacinth is probably best known for its very fast spreading and well-developed root system that absorbs nutrients from the water quickly.
At the same time, the leaves of water hyacinth are also extremely lush, and these lush leaves can effectively block the sun, and other aquatic organisms living in the water will not be able to survive because the sunlight is blocked.
Therefore, once the water hyacinth takes root in a certain body of water, the water area will soon become a dense green water forest, as if the water is covered with a thick green barrier, which will hide the otherwise clear water surface tightly.
The large and small lakes in the United States are not too much, but basically more than half of the waters of the United States have water hyacinths, and the crazy growth of this plant has also brought very serious damage to the water ecology of the United States.
First of all, the spread of water hyacinth will block the river, and after the river is blocked, the water flow in the water will become slow or even stagnant, which will seriously affect the self-purification ability of the water body.
In addition, the roots and leaves of water hyacinth can cause very serious damage to the habitat of aquatic organisms, and many fish and other aquatic organisms have no way to survive in the large areas of water hyacinth breeding.
In addition, water hyacinth will also absorb oxygen from the water, which will reduce the dissolved oxygen content in the water body, and other aquatic organisms living in the same water area will face a serious survival crisis.
The most terrifying point is that once the water hyacinth settles down in a certain body of water, it is difficult to be completely removed, and the time for water purification is slow.
Sometimes it can be as long as a hundred years, so people are often helpless when there is a water hyacinth rampant situation.
In the United States, the U.S. government is faced with the unscrupulous invasion of water hyacinth by water hyacinths, so the U.S. government has to take a series of measures to deal with them, and has invested a lot of manpower, material and financial resources.
They tried to control the growth of water hyacinth through physical and chemical means and spent tens of billions of dollars on controlling water hyacinth, but all these measures were not effective.
The life of water hyacinth is tenacious, even if a part of it is removed, it will soon grow again, and it will form a new green barrier, causing new water disasters, so solving the water hyacinth problem has become the most headache for the US government.
But it is this green nightmare that has plagued the United States for decades that has been solved by the Chinese.
«——【·Chinese Wisdom·】——»
Like the United States, China is facing the thorny ecological problem of water hyacinth, but in the face of these problems, the Chinese have not adopted simple and crude removal methods, but have shown unique wisdom and solutions.
Scientists from China, through in-depth research on the growth habits and ecological environment of water hyacinth, have found an environmentally friendly and economical solution, that is, biological control.
While many countries are intimidated by the amazing fecundity and vitality of water hyacinth, Chinese scientists are not panicked by this, but they see hope for solving the problem in the amazing fecundity and vitality of water hyacinth.
Through long-term observation and research, scientists from China have discovered the natural enemy of water hyacinth - water hyacinth weevil.
The water hyacinth weevil is a small insect that is related to water hyacinth as the name suggests.
That's right! This is a small insect that feeds on water hyacinth, and their existence is like a sharp sword given to humans by nature, and they happen to be the nemesis of water hyacinth, which can effectively control the number of water hyacinth.
After discovering that this small insect was effective in controlling the water hyacinth disaster, Chinese scientists began to introduce and release this small insect to allow it to reproduce naturally in the waters of the mainland, so as to start an ecological war against water hyacinth.
Water hyacinth weevils are tiny insects that are as fertile as water hyacinths, and they are able to reproduce quickly in a body of water.
As their numbers increase, a large army of creatures will form, and these small insects will attach themselves to the leaves of the water hyacinth and gnaw on the leaves of the water hyacinth.
This small insect has an amazing appetite, and it is very suitable to treat the water hyacinth problem with water hyacinth weevils, and over time, the ecological problems of water hyacinth with water hyacinth weevils have also been benignly verified.
After the water hyacinth weevil was introduced, Chinese scientists found that the number of water hyacinth weevils in the water area where the water hyacinth weevil was put into the water area would indeed show a significant downward trend after a period of time.
The water surface that was originally covered by water hyacinth has gradually revealed the rippling blue waves, and the water flow has become unimpeded again.
The habitat of the aquatic organisms living in this area of water has also been restored to a certain extent, and most importantly, the water quality of this area of water has been significantly improved, becoming more and more clear and transparent.
The successful application of this biological control method has not only effectively curbed the spread of water hyacinth, but also set a new model for ecological and environmental protection in China and even the world.
This also tells people that in the face of ecological problems, human beings should not only rely on physical and chemical means to eliminate them, but should pay more attention to the balance and stability of the ecosystem.
Human beings can solve ecological problems by introducing biological control methods such as natural enemies, which will also be more environmentally friendly and economical, and can better realize the harmonious coexistence of man and nature.
It can be seen that China's successful experience in facing the water hyacinth problem fully demonstrates China's wisdom and strength in ecological and environmental protection.
This wisdom is not only due to the in-depth research and technological innovation of Chinese scientists, but also inseparable from the scientific decision-making of the government and the active participation of the masses.
It is believed that in the future, China will be able to make more breakthroughs and innovations in the field of ecological environmental protection, and contribute more Chinese strength to the cause of global ecological environmental protection.
