When spring comes, the sky is full of flocculents! Is it feasible to cut down all the northern willo

In spring, plants begin to grow slowly in various places, branches sprout, and grass begins to sprout. These green sights make people aware of the past of winter and the arrival of spring. In many areas, people will encounter a lot of troubles while enjoying spring, that is, the flying flotsam flying everywhere in spring.

When the trees begin to sprout in the spring, poplars, willows and other trees will also begin to grow rapidly, and these trees all have one thing in common, that is, they will produce a large number of flying flotsam in the spring, which seriously affects people's daily life and affects people's travel to a certain extent.

Spring in the north is the season of high occurrence of flying, and in many northern areas, poplars, willows and other trees are the main types of trees in the city. Therefore, the north is also often plagued by the flying of such trees.

According to the forecast jointly issued by the Beijing Meteorological Observatory and the Beijing Municipal Bureau of Landscaping, from April 10th to 15th, there will be the first high incidence period of fly floc in the inner urban area of the Fifth Ring Road of Beijing, and the main fly floc tree species is poplar tomentosa. Due to the difference in tree species and environmental temperature, the flocculation period is generally from early April to late May and lasts for about 50 days in the whole city of Beijing. In specific areas, if there is no obvious precipitation, cooling, strong winds, etc., the fly floc will generally affect about 20 days, and the high incidence period is generally about a week.

In view of this situation, many cities in the north have also thought of many ways to deal with the problem of flying flotsam. Some cities use spraying or injections to suppress the flying of trees. However, the effect of most methods can only be seen for several years, so the control of fly floc is now a slow management process.

Some people also questioned why these poplars and willows could not be cut down and replaced with other trees. In fact, this simple and crude solution of cutting down trees will never work. Because these poplar and willow trees have been growing for many years, they have made a lot of contributions to urban greening, sand control, etc., and can provide shade and shelter for people who go out in summer.

Once cut down, it will cause serious damage to the vegetation area, and it will cause even more serious problems.

Not feasible! At the beginning, poplars were planted because they saw that they grew quickly, and they could grow into forests in two or three years, which played a role in preventing wind and sand, and planting other tree species not only did not grow as fast as poplars, but also had other shortcomings.

It is not feasible to cut down all the willow trees in the north, and the north is suitable for the growth of willows, if they are all cut down, then there will be no trees in the north, and the environment will become bad.

Of course, it is not feasible because if it is cut down, it will destroy the greenery, and it will be difficult to protect it well in the event of a disaster.

I think it's very unfeasible. Spring is originally a season of catkins, which is a very normal seasonal change. It is a very stupid idea to cut down a tree in order to prevent catkins from flying.

It is not feasible, because sometimes it can provide good help to people in life, it can maintain ecological balance, it can green the environment, it is very important.

This is not possible because it costs a lot of money to plant these trees, and if they are cut down, there will be no plants left to defend the city from the sandstorms.

That's not okay, it's too damaging to the environment, although there is a problem, but they are trees, they still have to exist after all, for greening.

This kind of behavior is also being implemented step by step, but there are still many people who will have a simple allergy to order, so this process has not been well implemented, and the process is still going on, and the willow tree can be cut down.

It's not feasible, and while it's really annoying, it's only around for a while. So there is no need to cut down all the willows.

In spring and summer, the catkins on the street are flying all over the sky, and many people have allergies on their faces, and they feel uncomfortable. Why is there so much catkins now, but not so many catkins in the past? If you are curious about this, you can take a look at the introduction provided by this site.

The previous poplar did not flutter, it was our local poplar variety, the old variety of the knot hair, can be eaten, the new variety is the American fast-growing poplar, the old bureau of fast-growing poplar, the fast-growing variety poplar, the growth rate is fast, the amount of groundwater is large, the poplar floc grows in May, the impact on the upper respiratory tract sensitive people is huge, the current planting of fast-growing poplar is still the first economic effect of Zen Lahengyi, green forest, papermaking, disposable chopsticks are necessary raw materials, the previous domestic old varieties of elm poplar, Willow trees and plane trees are thought to grow slowly, see low efficiency, cut down, have been to many places, basically difficult to see.

Catkins are available at this time of year, but fortunately, now everyone is wearing masks, and the allergies will not be so serious, and it will be good to stick to it for a while.

Seeds

Catkins, also known as willow cotton, are actually the seeds of willow trees. Every year in March and April, catkins float in the wind. Most of the time, it flies all over the sky, like snowflakes.

This thing is really annoying, and there are a lot of people who are allergic to it.
