The weather is getting better and better. The annual drama "Spring Snow" is released. On April 13th, the Hyundai Express reporter passed by the Qinhuai River. There was a lot of glimpses of hair on the road, and the river fell on the white. Garden experts told the Modern Express reporter that now is only the "primary stage." By the end of this month, Nanjing's Fatong "rainstorm" will strike in an all-round way.

Now catkins and catkins are floating

In the past two days, white fluff began to fly in the air, and many people wore masks. What is this turbulent white floc? Liu Xingjian, a senior engineer at the Nanjing Zhongshan Botanical Garden, told reporters that this season is mainly catkins and poplars.

When does the “flying snow” continue? According to Liu Xingjian, in normal years, Yang Xuo continued for about 3 weeks, catkins lasted for about 2 weeks, and Fatong Feixud continued for about 6 weeks. According to previous years' experience, the end of May at the beginning of June and the beginning of June of each year are the times when white wool is the most abundant, and it is expected to last until the end of June.

These flocs are not only allergic and irritating, they also block the radiator fins of cars and cause the boiler to turn off. They block the sight of pedestrians and vehicles and affect traffic safety. The floccule itself is flammable, and it can be burned quickly within 2 seconds in the event of an open flame. Many of the fire accidents in April and May each year are caused by flying floes.

Can I eradicate Yang Xuliu catkins for a short period of time?

Governance Yang Xu catkins, has been on the agenda for many years. This year, the Nanjing Municipal Bureau of Green Landscaping plans to renovate 18 green corridors in and out of the city's major expressways and high-speed railways in about 4 years, eliminating poplar trees along the way and replacing other tree species. At the same time, the poplar trees in the surrounding green areas of the downtown area of ​​Xiangyang River and the north side of Drum Tower Hospital will be updated. According to Li Ming, head of the Nanjing Landscaping Management Office, “The proportion of Yangshuo trees in Nanjing is declining, and Yangxue Liuxu problems will gradually improve, but it is not realistic to completely eradicate them in a short period of time.”

Reminder: "armed" and then go out again

The allergic people must have “armed” themselves in the last few days and go out again, wearing masks and glasses. Patients with bronchial asthma, allergic bronchitis, allergic rhinitis and other patients should focus on prevention next week, to minimize going out, when the wind is best to close the doors and windows at home.
