Evaluation of water hyacinth, hazards of water hyacinth

Reviews are mixed.

Water hyacinth can purify water, that is to say, polluted river areas, can be purified with water hyacinth, but it must be encircled, otherwise it will flood.

Water hyacinth can feed domestic animals, such as pigs and ducks, and it seems that feeding ducks is good! Very nutritious! As for making biogas, I don't know! Hehe... Hope it helps. Excerpts).

At first, China imported purified sewage from foreign countries, but because of its strong reproductive ability, it played a negative role, and the entire water surface was occupied, and the organisms under the water lacked oxygen and sunlight, resulting in a large number of deaths, and at present, various localities have to increase funds for cleaning up water hyacinth every year.

Hyacinth is not"Horses"

The hyacinth that I have seen can grow in COD is 162 mi L-374 mi LAmmonia nitrogen is

Sulfide is an extreme environmental water body, where bacteria X species, n million MI, virus Y species. M10,000 mi, which effectively suppresses carbon dioxide. Methane

Nitrous oxide. Sulfide gases. Greenhouse gases spill into the atmosphere, affecting terrestrial organisms and human survival, effectively absorbing Class V.

Carbon dioxide from inferior Class V water bodies. Ammonia nitrogen was stored. Phosphorus.

Potassium. Sodium. Heavy metals such as calcium and harmful substances release oxygen.

It purifies the air and water and inhibits the occurrence of the urban heat island phenomenon; It effectively reduces the dirt-holding burden of algae, especially cyanobacteria"Zhao Gao"Mr. and the like, there are such things in the world"harm"Grass? Please do not continue to bring calamity to the country and the people and their descendants.

I would like to invite our experts. Scholars question. Criticize. Guidance is also welcome"Zhao Gao"and stream attacks. Obloquy.

In South America it is an ornamental plant, but in our country it is a disaster. I don't think it's good.

The hazards of water hyacinth include blocking rivers, affecting navigation, and hindering drainage and irrigation. Moreover, as an invasive alien plant, water hyacinth will compete with native aquatic plants for nutrients and destroy the local ecological environment. At the same time, water hyacinth will adsorb a large number of harmful substances such as heavy metals, and will cause secondary pollution to water quality after death.

Water hyacinth covers a large area of the water surface, affecting the domestic water of residents and livestock around Li Sui, breeding mosquitoes and flies, and posing a threat to people's health. Water hyacinth can also clog the filter and affect the production of the water plant.

The ecological balance of an area is very important, and the balance can only be maintained when the species influence each other and the blind land inhibits each other. And the crazy growth of water hyacinth will largely upset the balance of the area and deprive other creatures of living space.

Water hyacinth is very harmful, but it is more sensitive to arsenic, can detect the degree of arsenic pollution in lake water, and water hyacinth can purify industrial wastewater, so it can also be cultivated in moderation.

The harm of water hyacinth is to destroy the ecological balance, it will rob the oxygen in the water, release a large amount of carbon dioxide into the water, lead to the death of fish and aquatic plants in a large area, and the growth rate of water hyacinth is faster, it will block the river, affect the flow of shipping and water bodies, and also make the filter of the water plant blocked.

What are the hazards of water hyacinth.

1. Destroying the ecology.

The harm of water hyacinth has to destroy the diversity of ecology, because water hyacinth has a strong reproductive ability, will grow vigorously in the water, inhibit the growth of other species, and fish, plankton, aquatic plants to rob the oxygen and nutrients in the water, and increase the concentration of carbon dioxide in the water, so that the fish and plants are wiped out in a large area.

2. Affect shipping.

The growth rate of water hyacinth is extremely fast, and in a suitable environment, it will grow on a large scale, which will seriously block the river, lead to paralysis of shipping, and water hyacinth will also endanger the production of the water plant, which will make the filter blocked, resulting in the shutdown of the water plant, which will affect the drinking water.

3. Variety introduction.

Water hyacinth is native to South America, also known as water floating lotus, phoenix eye blue, etc., its flowers are trumpet-shaped, with high ornamental value, and the stem height of water hyacinth can reach 50 cm, its leaves are broadly ovate or diamond-shaped, mostly grow in rivers or ponds, is a common aquatic plant in tropical and temperate tropical areas.

4. Double-sidedness.

Water hyacinth is extremely harmful, but it is sensitive to arsenic elements, can detect the degree of arsenic pollution in the lake water, and water hyacinth will absorb zinc, lead, mercury and other elements in domestic sewage, can purify industrial wastewater, and the stems and leaves of water hyacinth can be made into poultry feed, can be appropriately cultivated water hyacinth.

In the poem "On the River", the "water hyacinth" refers to a child swimming by the river. The author compares "water hyacinth" to a child playing by the river, which is a close-up of a child, giving people a vivid sense of image.

Water hyacinth, also known as water hyacinth, is a kind of aquatic plant in the water, which is a good plant to beautify the environment and purify water quality. Its stems and leaves hang over the water, and its tillers and branches creep on the water's surface. The flowers are multi-edged and trumpet-shaped, and the flower color is gorgeous and beautiful.

The leaves are emerald green and dark. The leaves are full-edged, smooth and textured. The fibrous roots are well developed, and the tillers reproduce quickly.

"On the River" is like a flock of ducks that have just entered the water, flapping Duan Tong's wings and slapping the water bureau to argue and play.

A pair of small hands are swaying the waves, and you make me laugh haha.

Which "water hyacinth" got into the water at once, and when it came out of the water, I saw a splash of water and two pairs of tiger teeth.

Translation: Children playing in the water, such naughty, a group of children jump into the water like a flock of ducks, splashing and playing with each other in the water. A pair of small hands plucked out a wave of flowers, just in this play, a child into the water, gone, suddenly a burst of water tung burned flowers, he appeared, naughty smile, showing two pairs of small tiger teeth.

Extended information: "On the River" is a poem from "Ink Painting in Childhood" by modern writer Zhang Jilou. His work "Ink Painting of Childhood" and Gao Hongbo's "I Think" were selected into the ninth lesson of the fifth grade of the People's Education Edition, "Two Children's Poems".

This children's poem captures a group of shots of children's life through three subheadings: "Street", "Streamside" and "River", showing the children's playful life scenes, intertwined with stillness and movement, forming a yearning picture of innocent childhood. It can be imagined that the children had a very happy childhood, or quietly reading, or calling friends to go fishing and swimming, and always enjoying the joy of childhood life.
