The sky is full of white flocculents, yellow flying hairs, and "black pearl" graffiti
Every spring
Nature creates a strong sense of atmosphere
Even the Tang Dynasty poet Han Yu wrote poems for this
"Yang Huayu pod has no talent, but the solution is to make snow fly in the sky"
However, this is a romantic rush
It also makes many people complain
Northern catkins: "Meet and share white heads"
The little friends in the north are feeling
"Beautiful and itchy" spring
Flying in the sky are the seeds of poplars, willows and other plants
A natural phenomenon of ripening and cracking
It not only carries a large number of viruses and pollen
There are also fire hazards
So, netizens came up with it
All kinds of strange coping tricks
01. Eat it
This method is not very practical
The edible ones are generally male inflorescences that have withered after pollination
And the fluttering female inflorescence is still hanging on the tree
02. Make quilts
No, it doesn't
The catkins themselves have short fibers and are inelastic
It is not easy to form a loose porous structure
Not only can it not be heated, but it will also cause discomfort to the human body
03. "Sex Reassignment Surgery"
Although this netizen has a clear mind
However, Professor Liu Yong of Beijing Forestry University said
Artificially bred male poplar tomentosa
"Jingxiong No. 1" has been put into planting
It not only protects the ancient poplar resources in Beijing
It can also help alleviate the problem of flying flotsam from the root
Expect!
04. "Beheading Capital Punishment"
Cut them all down and replant them
Both in terms of cost and time period
It's all unrealistic
Many people overlook the glorious mission of poplars and willows
North China 40 years ago
When faced with the threat of sand and dust in the spring
It was the poplar and willow that stepped forward
Carried the North China Plain
The climate and environment of severe cold winter, dry spring and high temperature in summer
It has become the mainstay of windbreak and sand-fixing tree species
Effectively improve the quality of the environment
Sycamore in Nanjing: "Wash your hair" at night to keep it dry
It is different from the "white hair" of willow catkins
Nanjing's sycamore catkins are yellowish-brown
A two-ball plane commonly known as the "French plane tree".
It has the advantages of fast growth, thick shade, and resistance to pruning
But every spring "fried hair"
March ~ May every year
Nanjing will "wash the hair" of the big trees at night
Take fog cannon truck blowing flocculent and sprinkler truck flushing
Sweeper sweeper and other "blow sweeping" combination mode
Effectively alleviate the problem of sycamore flying
"Bird poop wind graffiti" from nature
Every spring
Southern friends have another problem
Recently, Mr. Wang from Hangzhou, Zhejiang
It was hit by a "black bomb"
on the road near their workplace
There are a lot of black fruits dropped
"Step on it and burst juice,
Not only is the ground dirty,
My clothes were also accidentally dyed. ”
There are also cars that have been subjected to "air strikes".
It was ruthlessly coated with a layer of "bird feces wind" car film
Researcher at the Institute of Subtropical Forestry, Chinese Academy of Forestry
Jiang Jingmin pointed out
These are the fruits of the camphor tree, camphor seeds
will color the surface of the object
If the garment is unfortunately stained
Can be mixed with soap or detergent with water
Allow to soak for a few minutes and then scrub off
Although camphor seeds are not edible, they are still "graffiti"
But the camphor tree is in the Gangnam area
It is the most widely used tree species for urban and rural greening
It is easy to survive, has few pests and diseases, and has a large canopy
It has the effect of sterilization and air purification
Camphor wood is also a superior material in furniture
Every tree has a purpose for existence
I hope that everyone can effectively prevent flying flotsam and fruit falling
And embrace these lives with an inclusive mindset
And thank you to each and every one of them
Sanitation workers who silently do the cleaning work
Kudos to them!
