How harmful are poplars? Why don t you let the seedlings that have been introduced by the huge amoun

For sensitive people, poplar catkins are particularly easy to cause respiratory tract infections or lung infections, and there are caterpillars on poplar trees, and these insects are easy to cause ** diseases due to bacterial infections; Because poplar catkins and caterpillars on poplar trees can have a significant impact on people's health, it is possible to seek medical attention in time in serious cases, which will do more harm than good.

Poplar trees have a lot of poplar catkins, which make people feel very annoyed in the spring, and some people will feel uncomfortable when they are allergic, and they don't even dare to go out; Because poplars bring a lot of inconvenience to people's daily life.

It is easy to cause fires, which seriously affects people's safety, in the beginning because it is easier to survive, and now it is to protect safety and avoid poplar hair.

With the continuous expansion of urban greenery, many tree species have begun to be widely planted, but poplar is an exceptionIn many places, there has been a large-scale felling of poplars, and even the roads connecting rural and urban areas are gradually not visible, which is due to the poplar catkins produced by poplars, which have serious harm to people and dealers

In many cities in the north, poplar catkins fly all over the sky every spring and summer, which causes great trouble to our daily life。On the one hand, if poplar catkins get into the eyes, nose, and mouth, it will cause rashes and allergies in mild cases, and respiratory infections in severe cases。Long-term exposure to poplar catkins and inhalation of the human body will also endanger the normal operation of organs in the human body.

Many people who are allergic or have nasal allergic diseases will have an uncomfortable reaction when they come into contact with poplar catkins. <>

On the other hand, in recent years, the global temperature has generally risen, the air is drier, and the flying poplar catkins will easily become ignition because of the long fiber and low ignition point

In addition, there were news reports in the early days, because:There is too much white and vast expanse of poplar catkins, which can easily block the driver's vision and cause traffic accidents. If the poplar floc produced by poplar trees flies to the wheat field, it will also affect the wheat and even lead to a reduction in wheat production, which is also a heavy blow to farmers

In the past, poplars were very popular, not only because they grew well, but also because poplars were also a good choice for wood. JustUnder the influence of climate, environment and quantity, the disadvantages of poplar trees have gradually emerged, and they have also become a serious threat to our daily life, agricultural production and even life safety。Therefore, many places have begun to restrict the planting of poplars, not to completely ban planting, but to plant poplars in places that are suitable for their growth without affecting our lives, so as to ensure that the advantages of poplars can be used rationally, and its harm can be avoided from affecting citizens and crops.

The main reason is that poplars will produce poplar flocculents, which will cause a lot of harm. Mainly because poplar catkins can cause a lot of problems.

It is mainly forbidden because the cultivation of poplars requires the occupation of arable land, which reduces food production.

The main reason is that poplars will produce a large amount of poplar flocculation in spring, which will pollute the environment, so they are not allowed to be planted.

Because the poplar trees now have poplar catkins in April and May, which will pollute the air.

It is because the taste of poplars is relatively large now, and poplars are particularly easy to absorb catkins, which does not look very beautiful.

Mainly because there is no shortage anymore. Now everyone wants to cut down poplars, after all, poplar cotton wool growing in summer is really uncomfortable.

Because poplars have now proven to be ineffective in controlling soil erosion, and the cost of poplars is still relatively high.

Poplar is a very common plant in our country, usually planted on the side of the road, as a street tree.

Because poplars can grow taller, they can have a shade effect in summer. Although poplar has many advantages, but a large number of introduced planting in China has been disliked by many people, because poplar to people's lives bring danger and early damage even more than they can bring. Poplar trees will produce a large amount of poplar catkins in spring, which is not good for people's health and also poses a greater safety hazard.

There are many people's ** is more sensitive, if in contact with poplar catkins, it is likely to have itching, redness and other allergies, so many people will wrap themselves tightly when they travel in spring. And if some people have a respiratory system.

diseases, such as asthma.

If inhaled, it is likely to cause the rapid occurrence of diseases and pose a threat to the safety of the human body. At the same time, too much poplar will also block the driver's vision when driving the car, resulting in traffic accidents.

Poplar catkins can be scattered with the wind, so the distribution range is very wide, and its own ignition point is very low, once it encounters a Mars, it is likely to have a large area of fire, which is very dangerous. For this reason, poplars are excluded from the consideration of late renting when planting street trees in many places.

However, only female poplars produce catkins in the spring and drift away in the wind, which can be very well alleviated if male poplars are planted. In addition, poplars have the advantage of growing quickly and not being susceptible to pests and diseases, so poplars are still widely used in daily life and can be used to make disposable chopsticks. But now more and more people realize the importance of environmental protection and resist the use of disposable chopsticks, which makes many people misunderstand poplars, people use fast-growing poplars when making disposable chopsticks, and will not cause harm to wild poplars.

Poplars will have poplar cotton, which will be piled up at home or in the field, which will affect people's breathing, and orange resistance will even make ** allergies.

In the past, in order to increase the forest coverage, a large number of poplars were planted in China. However, poplars have great harm, fluttering poplar catkins will aggravate the symptoms of respiratory diseases, and some people believe that they are allergic to poplar catkins, and they will have red rashes when they come into contact with them. And the water content of poplar floc is very low, and the contact area with air is very large, and a spark can light it, so once the poplar floc wheel catches fire, the fire will spread rapidly, and it is often too late to extinguish.

This is due to the fact that the catkins emitted by the poplar trees have affected the environment. These catkins float in the air, and the manuscript stool will cause rhinitis to trigger many people, and it will also lead to the destruction of the environment, which will make it difficult to clean the imitation environment.

In fact, the harm of poplar itself is not very large, but poplar catkins. Yang Fu is like gunpowder. Very flammable in case of fire.

In addition, the poplar catkins in the sky have also caused great pollution to the environment. Some people are allergic to poplar catkins and will develop a red rash. If someone suffers from a respiratory disease, it can even worsen the condition.

At the same time, the driver is easily disturbed by the floating poplar catkins, and the branches and ants are very easy to cause accidents in the town.

The compensation standard for poplar land acquisition is: an average compensation of 6,000 yuan per mu for 1-3 years; 4-13 years of average compensation per mu of 12,000-36,000 yuan; In 14-20 years, the average compensation per mu is 60,000

80,000 yuan; For more than 21 years, the average compensation per mu is 32,000 yuan. Compensation is different in each locality, and there is no uniform standard across the country.

Summary. Poplar has many advantages, but it also has some disadvantages. Poplar may inhibit the growth of other tree species because its unique root structure helps it accumulate as much nutrients as possible such as nitrogen, phosphorus, and potassium in a relatively small space, which can inhibit other tree species from being deficient in nutrients.

In addition, the leaves of poplars may also destroy the leaves of other tree species, interfering with their photosynthesis and thus inhibiting their growth.

What are the advantages of nursery poplars compared to poplars in the market?

The crown of the nursery poplar tree is more neat, the shape is more pure, the style is more beautiful, and it is easier to prune;3.Nursery poplar has a more sound root system, grows faster and is easier to maintain4.Nursery poplars are more affordable,** lower than poplars on the market.

Compared with the poplar trees in the nursery, which one grows faster?

Nursery poplars grow faster, because nursery poplars will appear soon after planting in the nursery poplars, and most of the poplars on the market are carefully cultivated and managed to reach the state of maturity.

Which grows taller than a nursery tree or a normal tree?

In general, nursery trees grow faster than normal trees, so nursery trees are generally taller in length than ordinary trees.

If the nursery poplar and the ordinary poplar are planted in the same field, which type of volume will be higher after the forest is formed in the future?

In general, the volume of the common poplar will be higher because the common poplar grows faster and has a longer growth period, so the final volume will be larger.

So I want to plant forest trees, and from an economic point of view, cut down in 10 or 20 years, should I plant ordinary trees or nursery poplars?

It depends on your goals and financial returns. If you want to reap the benefits in a short period of time, then common trees are a good choice because they grow faster and can be cut down in a shorter period of time. If you want to reap the benefits over a longer period of time, then nursery poplars may be more profitable because they have a long growth cycle and can get more wood when they are cut.

It is recommended to nurse poplars for a short period of time, and for ordinary trees for a long time.

Experts, there are many varieties of poplars in Puqiao Chilutong on the market, please recommend a variety for me, grow fast, grow high stool, and have advantages over other varieties of poplar varieties.

I recommend the goldenrod poplar (widely buried populus alba'jinye'）。Golden-leaved poplar is a hybrid poplar that is able to grow quickly, has a high dull height and erectness. In addition, the golden-leaved poplar tree has deciduous leaves, and its leaves are golden yellow and curved, and the branches are slender, which can enhance the beauty of the forest.

In addition, poplar is highly resistant to disease, can tolerate drought, cold, salt, acid and alkali, and can grow well in various soil and environmental conditions.
