In the past two days, Beijing has ushered in continuous windy weather, and some netizens said that they didn't seem to see the flying flakes flying around, was it blown away by the strong wind at one time? In this regard, Che Shaochen, senior engineer of Beijing Academy of Landscaping Sciences, introduced the relevant situation.
車少臣:根據北京市園林綠化局楊柳飛絮第一高發期的預測預報,從今年的4月4日到4月5日開始,正值毛白楊飛絮的高峰期。由於12日和13日的大風天氣,風力級別較大,城區達到9至11級,大部分毛白楊飛絮已經隨著大風提前被風吹落,包括擴散,一些未成熟的雌株花序也從樹上被吹落。因此毛白楊這次飛絮基本結束。
With temperatures soaring rapidly next week, Tuesday is expected to reach above 30°C. The flocculation period of willow trees will come earlier, and the inflorescences of poplars, including European and American poplars, will also ripen one after another, nearly a week earlier than in previous years.
The gale also caused the lodging of the willow trees. Poplars are relatively tall and have a relatively high proportion of lodging numbers. After this strong wind, on the one hand, it is necessary to prune to reduce the number of flying floc, and on the other hand, other emergency treatment measures should be taken in time to replenish the water of the tree.
