Preface
Recently, with the large-scale planting of poplar trees, poplar flocculation has also become a controversial topic. In May and June every year, poplar catkins fall away, which brings a lot of inconvenience to people's lives and even has a certain impact on people's health. In the face of the pollution problem of poplar catkins, experts have not given a clear solution, nor have they spoken out about it, why is this? Is it because they don't realize the dangers of poplar catkins, or because they can't find a solution? This article will discuss this, hoping to give you some inspiration.
First, the promotion of poplar catkins has caused harm to people's work and health
Yang poplar flocculation is the fruit of poplar when it blooms and bears fruit, and it is also a way of propagation of poplar trees. The poplar tree, also known as the "urban green lung", because it can absorb harmful gases, purify the air, and play a certain role in improving the ecological environment of the city, so it is planted in a large number of urban greening projects.
However, with the large-scale planting of poplar trees, poplar flocculation has also become a more difficult problem. In May and June every year, poplar catkins will fall down in a large area, like "snowflakes", which has a certain impact on people's travel and work.
First of all, poplar catkins will have a certain impact on people's travel. When the poplar is more serious, there will be a decrease in visibility, which will bring certain hidden dangers to the driver's sight and be prone to traffic accidents. Moreover, poplar catkins will also drift to the road with the wind, like snow, adding a certain degree of difficulty to the road cleaning work, and it is also easy to cause traffic congestion.
Secondly, poplar catkins will also have a certain impact on people's health. The fall of poplar catkins will be accompanied by a large amount of pollen, which may aggravate their allergy symptoms such as sneezing, runny nose, nasal congestion, etc. Moreover, poplar catkins can also cause some respiratory diseases, such as bronchitis, asthma, etc., for patients with respiratory diseases, it may aggravate their condition, lead to breathing difficulties, and even induce other complications.
It can be said that the fall of poplar catkins has brought a lot of inconvenience to people's lives, and also added a certain degree of difficulty to the city's environmental sanitation work, so how to effectively solve the pollution problem of poplar catkins has become a problem that needs to be solved urgently.
2. Why experts have not spoken out and proposed solutions
In the face of the pollution problem of poplar catkins, experts have not given a clear solution, nor have they spoken out about it, why is this? Is it because they don't realize the dangers of poplar catkins, or because they can't find a solution?
In fact, experts have not spoken out about the pollution of poplar catkins, probably because they are not aware of the actual impact of poplar catkins on people's work and health. In the opinion of experts, poplar is a relatively high-quality greening tree species, which can absorb harmful gases, purify the air, and play a certain role in improving the ecological environment of the city, so they do not realize that the fall of poplar will have a certain impact on people's lives.
In addition, experts have not come up with a solution to the problem of poplar pollution, probably in part because they have not been able to find an effective solution. At present, the treatment of poplar flocculent is mainly through manual methods, such as the use of water spray trucks for dust removal, or the use of chemical fly floc to sterilize poplar trees to reduce the fall of poplar flocculents.
However, the use of water spray trucks for dust removal may not be particularly effective for poplar flocculents, because the poplar flocs are relatively light in size, difficult to dust by water, and will also increase a certain amount of water consumption. The use of chemical fly flotsam to sterilize poplar trees may have certain risks and side effects, causing certain impacts on the environment and human health, so more research and evaluation are needed.
In addition, the experts did not propose a solution to the pollution problem of poplar catkins, and it is possible that they did not have sufficient resources and support to carry out relevant research and implementation. After all, the pollution problem of poplar flocculent involves many fields such as ecological environment, agriculture and forestry, and requires interdisciplinary research and cooperation, and at present, there are not many studies on poplar catkins in China, and experts may not have enough resources and support to carry out related work.
3. How to effectively solve the pollution problem of poplar flocculent
In view of the pollution problem of poplar flocculents, we cannot blindly cut down poplar trees, which is not a long-term solution and will also damage the ecological environment of the city. Instead, we should use scientific methods to effectively solve the problem of poplar pollution.
First of all, we can make a lot of efforts in the selection and management of poplar trees, and select some poplar species that are not easy to float for breeding and planting, such as poplar without children, poplar without fecundity, etc., to reduce the fall of poplar flocculents. At the same time, in the pruning and management of poplar trees, the size and density of the canopy can be appropriately controlled to reduce the generation and fall of poplar flocs.
Secondly, biological control can be used to reduce the fall of poplar catkins. Some insects that have natural enemies of poplar flocculents, such as the natural enemies of poplar flocculents, can be studied to introduce, breed and release to control the number of poplar flocculents, so as to reduce the fall of poplar flocculents.
In addition, scientific and technical means can also be used to reduce the fall of poplar catkins. Some materials that have an adsorption effect on poplar catkins, such as nanomaterials, biological materials, etc., can be studied to spray and cover to reduce the fall of poplar catkins, and at the same time, they can also play a role in purifying the air.
Of course, in addition to these aspects, we also need the participation and support of all sectors of society, government departments, scientific research institutions, enterprises, the general public, etc., should join hands to jointly pay attention to and solve the pollution problem of poplar catkins, and contribute to the construction of the city's ecological environment.
epilogue
The pollution problem of poplar floc is a relatively complex system project, which requires us to carry out comprehensive treatment from many aspects, and also requires a long-term process. I hope that through the efforts of each of us, more and better solutions can be found, and I also hope that experts can give more attention and support to solve this problem together, so that our city will become more beautiful, and people can better enjoy a green life.
