Many people who are prone to allergies
To put it bluntly, I suffer from it...
There are 3 main types of fly flotsam in Shanghai!
Next week, Guomao will focus on "spreading joy"
It lasts for more than a month
Yang Ruiqing, chief of the street tree section of the Municipal Greening Management Guidance Station, said that the plant wool fluttering in Shanghai in spring mainly comes from plane trees, poplars and willows. The fluff of willow and poplar trees is their seed, and the fluff of plane is mainly its fruit hair. At the same time as the fruit hairs are shed, the newly-born male inflorescences of plane trees also scatter a certain amount of pollen.
Compared with plane trees, willow and poplar trees are mainly planted in parks and green spaces, and there are fewer on both sides of the road, so plane tree fruit hair is the main source of road flocculation in Shanghai.
The municipal greening department said that from next week, the fruit hair will be concentrated on "spreading joy", and the follow-up will be the white floc of poplars, which will last for more than a month.
How to reduce fluffing?
The municipal greening department has taken multiple measures at the same time!
Pruning the branches of plane trees in winter has always been a good way to remove the fruit bulbs. However, some roads are too narrow for climbing vehicles to enter the site, which makes it impossible for green workers to go up the trees to carry out effective pruning.
However, the inability to prune does not mean that there is no way to manage the hair of these roads. The relevant person of the Municipal Greening Management Guidance Station said that the follow-up will use physical "blowing" to reduce fruit hair depending on the situation of flying flocculents.
In addition, the scientific research team also selected a small number of plane trees in Jing'an, Xuhui, Pudong, Baoshan and other districts for "clinical trials", or sprayed "external dressing" on plane trees to inhibit the growth of fruit balls and let them wilt as soon as possible, or injected "internal medicine" with a syringe to control the differentiation of female flower buds, interfere with the female plant setting or make flower buds unable to develop normally by adjusting the endogenous hormone level of plane trees, which also plays a role in less fruit and no fruit.
fly floc is easily sensitized,
Be sure to protect yourself when you go out!
It is understood that the fruit hair itself is not poisonous, but for some people with sensitive physique, it will cause allergic reactions such as respiratory discomfort.
Wang Zheng, director of the Department of Otolaryngology at Songjiang Hospital Affiliated to Shanghai Jiao Tong University, suggested that sensitive groups wear long sleeves, masks, and protective glasses when going out, and try to avoid going to places with dense flying flotsam.
If you have severe allergies and cause asthma and other symptoms, you should go to the hospital for treatment in time.

Do not ignite the fly flocculent to clean up,
Beware of provoking "fire"!
Flying flotsam not only has an impact on everyone's life and travel, but also has a great fire hazard.
Because the catkins contain a lot of oil, once they encounter an open flame, they are very easy to ignite and spread quickly.
In recent years, there have been cases of "igniting catkins and causing fires".
May 2022
A man in Jinan, Shandong Province, was allergic to poplar catkins and ignited them in a fit of rage, and the fire spread rapidly, burning two private cars and a number of scrapped vehicles. Eventually, the man was subjected to criminal coercive measures.
April 8, 2021
A fire broke out in a foam profile processing workshop in Botou City, Cangzhou, Hebei Province. According to the on-site investigation of the fire department, the cause of the fire was caused by the ignition of the surrounding foam profiles when the employees were cleaning up the catkins by ignition, but fortunately there were no casualties.
Fire Department Reminder:
Absolutely not by way of ignition
Cleaning up the catkins,
Look at it the right way!
