Why is the water hyacinth that used to be planted in ponds in the countryside now not planted?

It was already flooded before, and there was no way to catch it, and of course no one planted it. Water hyacinth originated in Brazil. It is widely distributed in the Yangtze River, the Yellow River basin and southern China.

Like a warm, humid and sunny environment, it is also very adaptable and able to withstand growing in ponds, ditches and rice paddies at heights of 200-1500 meters. The tropics of Asia are also widely developed. Due to overbreeding, waterway blockage, and traffic impacts, water hyacinth is usually located in a suitable growing area.

Water hyacinth has been introduced to many countries, is widely distributed around the world, and is listed as one of the top 100 invasive alien species in the world. The whole grass is fodder for livestock and poultry, and the young leaves and petioles can be used as vegetables. The whole plant can also be used for medical purposes, such as cooling and detoxification, dehumidification, phlegm and external application of heat, heat wounds.

There are many water hyacinths in our hometown every year, and it is difficult to basically clean and actively grow every year. But water hyacinth also has a certain value, for example, the purification of the water quality mentioned above can improve the water quality and make the sewage appear fresh again. Of course, it is also a pig feed, so many farmers catch some to take home to feed their pigs, and end up consuming a lot of protein to supplement nutrients while reducing feed costs.

Of course, water hyacinth can also be consumed, especially fresh stems and leaves can be used well, and of course can also be used as medicine. It looks like it works a lot, but in fact it can replace other plants, so it has no special economic value and there is harm to the environment.

As a floating creature, it can float in the water, but it is very fertile and grows rapidly every time it floats to a place. The leaves are large, and the fish under the water have no sunlight and die easily. What's more, since water can absorb a lot of nutrients and oxygen, only a small number of vital fish species will survive the death of aquatic organisms, so in recent years all areas will be cleaned up with a prioritization.

That's because things like water hyacinth are now flooded and don't need to be planted.

Because it has now been eliminated, there is no other crop of value.

Mainly because the ** and sales of water hyacinth are not very good, so it was eliminated.

Rural domestic sewage can be used to grow rice, lotus root and aquatic weeds, fully absorb and utilize the organic matter and a large number of inorganic salts in the sewage, so that the sewage loses a large number of pollutants, so that the water quality is basically close to the natural water quality. Achieve the purpose of rural sewage treatment, reduce the cost of sewage treatment, and save investment in agricultural fertilizers.

Mainly because:Water pollution control is relatively successfulIn the past, most of the rivers were seriously polluted, and the water bodies were seriously eutrophicated, smelling all day long, and smelling for 800 miles. The more water hyacinth is in this environment, the more vigorous it grows. Strangely, in an environment with good water quality, water hyacinth can hardly survive.

So putIf the water pollution is well controlled, the water hyacinth will naturally disappear。The better the water hyacinth grows, the more polluted it is. Water hyacinth was originally used to control pollution.

Rural domestic sewage is used to grow phytoplankton such as water hyacinth. The use of large ponds to collect aquatic plants such as water hyacinth and duckweed from rural wastewater farming can transform organic matter and a large number of minerals available to plants in sewage. After the sewage is absorbed and used by plants, the water quality basically meets the standard and can be discharged into nature.

These aquatic weeds are excellent green fodder for aquaculture, poultry farming and animal husbandry.

The reproduction of water hyacinth relies heavily on two factors: one is nutrients and the other is the temperature of the water. River water with high nutrient content is usually sewage, and river water with higher water temperature is due to the involvement of a large amount of oxidation.

In fact, the two complement each other. A negative cycle is formed and adapts to the growth of water hyacinth. Water hyacinth is a biological invasion to some extent, so it has been destroyed by a large number of people for a period of time, but some merchants have found that water hyacinth can be used to feed pigs, it is good pig feed, so water hyacinth can survive for a period of time.

Why is the "water hyacinth" that used to be planted in ponds in the countryside now not planted? Farmers also know that water hyacinth has a strong reproductive capacity, but as long as it is controlled in one area, it will not spread to other places. In addition, a variety of herbicides were invented in previous years.

In order to reduce the damage of weeds to crops, farmers use a lot of herbicides, which is also the reason why water hyacinth disappears in rice paddies, canals, etc. There are also small rivers and ponds that have dried up and are backfilled. Without water, there is no water hyacinth.

1. Water hyacinth is an invasive species, just like water peanuts, known as revolutionary grass. This plant comes from as far away as South America and was introduced to China as early as the early 19th century. Because there is a part of the gourd-like swelling between the roots and leaves, and it mainly grows on water, it is called water hyacinth in Chinese folk.

In fact, its scientific name is very good - crested blue. In the past, it was not a terrible invasive species, but a popular ornamental plant. It is said that after the Empress Dowager Cixi introduced it to China that year, she specially planted it in the Old Summer Palace and loved it very much.

Not to mention, after the water hyacinth blooms, the purple flowers and green leaves are really beautiful. At that time, many countries introduced water hyacinth as an ornamental plant.

2. In addition, water hyacinth has another characteristic, that is, it can adsorb heavy metals in water and play a role in purifying water quality. Therefore, many countries have introduced water hyacinth, believing that it can not only be ornamental, but also purify water quality, killing two birds with one stone. However, it was later discovered that although water hyacinth can adsorb heavy metals in polluted water, when they decay, the adsorbed heavy metals return to the water body and cannot purify the water quality.

Since then, the strong vitality of water hyacinth has been gradually discovered. They have a strong reproductive ability and cause great harm to the local ecological environment. However, it was too late.

This has become a disaster in many places.

3. I have to say that the reproductive ability of water hyacinth is really terrible. Water hyacinth can breed a water hyacinth in about 5 days, and this water hyacinth can continue to grow after 5 days. In this way, under the right conditions, water hyacinth can propagate nearly 4,000 plants in a month.

Some netizens may wonder why water hyacinth is not rampant in the country of origin, but in the country of introduction? This is mainly because its native South America has a natural predator that specializes in eating the leaves of the hyacinth, so it cannot photosynthesize and cannot reproduce in large numbers.

Water hyacinth is an alien species, it will cause great harm to our environment, its noisy raw liquid jujube growth speed is not noisy and often fast, will quickly cover the water surface, which will make the water oxygen node less, resulting in fish can not survive.

Because water hyacinth is particularly difficult to manage, it is very labor-intensive, and the profit value is not high, and there is no market.

Because this crop is not highly profitable, and the growth cycle is very long, it is not profitable at all.

It is because this kind of water hyacinth can be completely converted into greenhouse grinding and macro breeding, and the coarse and breeding cycle is still very short, many people are also blind and unwilling to plant, simply buy it directly.

1. Everyone must know that water hyacinth is a plant, and you can see this plant in any pond you see. It is born inseparable from water and grows in water, but once it is abundant and permeates the water, then other creatures in the water will suffer. Because if the water hyacinth fills the entire pond, it will block the way for outside air to enter the water, which is equivalent to organizing the reproduction and growth of all organisms in the water.

Therefore, in order to control its growth, China also thought of many ways.

2. Now the growth rate of water hyacinth has been greatly controlled, but it cannot be found in many rivers. This can't help but make many netizens wonder where it went, is it because the idea of wanting to take root in the river has not been realized? Actually, no, we don't see a lot of water hyacinth in the river now, in fact, because it has other uses.

3. Although the appearance of this plant was a scourge for us at first, as scientists carefully studied it, they found many benefits for it. Because scientists want water hyacinth to work well on our lives, there is a lack of water hyacinth in the river. There are so many benefits of water hyacinth, and its usefulness has increased, so let's introduce them below!

4. The first one must be easy for everyone to think of, that is, it can be made into feed. The biggest advantage of water hyacinth is that its reproductive ability is very strong, so in order to solve this problem well and avoid its own waste, making feed is the best way. Moreover, water hyacinth is actually a high-protein plant, and giving it to livestock can not only fill their stomachs but also enhance their immunity.

And because there are many water hyacinths, its cost is relatively low, and it is also very economical as feed. Although the process of making feed is somewhat difficult, it does not affect its use.

5. Secondly, water hyacinth can be fertilizer, and the process is simpler. There are still many people in our country who choose to farm for a living, and for them, fertilizer is very important if they want to cultivate good crops. At this time, the potential of water hyacinth has been discovered, it is not only cheap, but also can be directly used as fertilizer after drying, and its nutritional value is not low.

6. There is also the fact that it can be made into fuel, and the large output of water hyacinth is far from enough to rely only on feed and fertilizer consumption. So scientists have come up with a good way to use it as fuel, after drying the water hyacinth, part of it can be used as fertilizer, and part of it can be used as fuel, which is very convenient. In addition to drying, it can also be fermented before being used as fertilizer, but this process can be complicated, so it is not used very often.

7. Now there are also people who use water hyacinth as a raw material for making drinks, because of the nutritional value of water hyacinth and its green safety, many manufacturers are competing to study, maybe one day in the future we will drink water hyacinth flavored soda! Water hyacinth is used so much, no wonder there is a lack of its shadow in the river!

Growing water hyacinth in freshwater lakes is not environmentally friendly. Planting water hyacinth has the following hazards:

1. Cause ecological damage.

One of the hazards of water hyacinth is that it will lead to ecological destruction, because its reproductive ability is very strong, if the living environment is suitable for the growth of water hyacinth, then it will reproduce in large numbers, and become a dominant species, affecting the growth of other organisms, in the long run, the ecological diversity of the area will be destroyed, and make it a single species.

The ecological balance of an area is very important, and the species can influence and inhibit each other in order to maintain balance. The wild growth of water hyacinth will largely upset the balance of the region, depriving other creatures of living space, and making some species endangered.

2. Affect the growth of other organisms.

When the water hyacinth is growing vigorously, it will fill the entire water, covering the entire water surface and dyeing the water surface green. At this time, it will affect the exchange of gases in the water and the atmosphere, as well as the transfer of light, and will increase the concentration of CO2, affecting aquatic life.

3. It will block the river.

Wildly growing water hyacinth can clog waterways. Because the water hyacinth plants multiply in large quantities, the plants continue to increase, and soon Bisan will cover the entire river, and in severe cases, the density of the water hyacinth growth can even make people walk on it, affecting water transportation. In addition, the growth of water hyacinth can even affect the growth of tap water in the water plant, as over-propagated water hyacinth can clog the production equipment of tap water.

Water hyacinth can be planted in the soil He Xichang. When the soil raises the water hyacinth, the humus soil and the garden soil can be mixed to prepare the land. After that, it is best to disinfect the soil in the sun.

Water hyacinth is a light-loving plant. When raising water hyacinth in soil, it is best to place the plant in a well-ventilated and well-lit environment, which is conducive to plant growth. Water hyacinth does not require much soil.

As long as the soil is loose and can absorb water for a long time, water hyacinth can be planted. In general, water hyacinth is cultivated at home, with some soil in a pot and placed on the balcony.

Water hyacinth soil culture planting method.

1.Potting soil water hyacinth does not have high soil requirements. When planting, it is best to choose loose, fertile, breathable, well-drained sandy loam soil.

Usually, you can mix humus, garden soil, river sand, and perlite to prepare soil for planting. 2.Plenty of sunlight Spring and autumn are the growing seasons for plants.

At this time, it is best to place the plants indoors in a well-ventilated, well-lit environment with strong sunlight in the summer. At this point, it is best to place the plants in a semi-shaded, well-ventilated environment. 3.

Control the temperature. Water hyacinth prefers to grow in a warm and ventilated environment. When planting, it is best to control the temperature at around 20-30 degrees.

This is when water hyacinth grows the fastest. 4.Properly watered water hyacinth is an annual floating plant that has a high demand for water.

It is also okay to water more often, and then you can grasp the amount of watering according to the growth of the water hyacinth.
