Tianjin North network news: the good season of brilliant spring is also the peak flying period of Yang Xu. With the rising temperature, the flying poplar catkins not only affect the city appearance and environment, but also affect the air quality. There are certain fire hazards when they stay in clusters. Therefore, Tianjin Port Co.Ltd(600717) free trade zone has carried out special prevention and control actions for Poplar catkins. Through "drug intervention, canopy spraying, increasing collection frequency" and other methods, combined fist attack, accurate prevention and control, and effectively inhibit catkins.
It is understood that poplar is a local tree species planted in the early stage of the city, with a large number. The warm spring flowers bloom every year is the period of poplar reproduction. Floating catkins are a way of pollination and breeding for female plants. White catkins will fall from the trees one after another, and can be seen everywhere on the roadside and sidewalk. Due to the fast growth, easy survival and rapid landscape formation of poplars, Populus tomentosa was planted around the airport industrial zone in the early stage. The Urban Environmental Protection Bureau of the free trade zone passed the Mopai, and these poplars were concentrated on both sides of the West 6th Road, West 7th Road, Xinghang Road, East 7th road and other roads in the airport area.
In order to effectively reduce the impact of flying catkins on the lives of regional residents and enterprise production, the Urban Environmental Protection Bureau of the free trade zone and Jinbao environmental investment group have taken comprehensive measures to prevent and control flying catkins. In terms of drug intervention, female poplar plants were injected with "gibberellic acid" injection for several consecutive years to inhibit the growth of catkins. Gibberellic acid is a plant growth regulator, which is harmless to plants and human body. After injection into the tree, it will spread to all parts of the crown with transpiration. It can adjust the reproductive nutrition of poplar to growth nutrition and weaken the flower bud differentiation of poplar, so as to achieve the purpose of controlling poplar catkins. At present, 7700 strains have been injected.
At the same time, the Urban Environmental Protection Bureau of the free trade zone organized 8 mechanized vehicles from the environmental sanitation department to carry out the special cleaning action of poplar catkins by adopting the operation mode of combining canopy spraying, ground humidification, washing and sweeping vehicle cleaning and manual cleaning. The sprinkler flushes the floc falling on the ground to the roadside, the washing and sweeping vehicle cleans the ground, and then the sanitation workers and small road washing vehicles finish it, so as to achieve a good effect of floc cleaning.
At present, the poplar trees with flying catkins were planted in the city in the early years. With more and more enterprises and residents settled in Tianjin Port Co.Ltd(600717) Free Trade Zone, the regional landscape environment has higher requirements. In recent years, the free trade zone has been more abundant in the selection of greening tree species. Tree species with beautiful tree shape and strong ornamental, such as Fatong, Luan, gingko and purple autumn, have been planted in the free trade zone, which not only achieves the diversity of tree species, but also enriches the regional landscape effect and further optimizes the business environment.
There is no trivial matter in people's livelihood, and the branches and leaves are always concerned. Through the combined fist attack and precise prevention and control, the prevention and control of catkins in Tianjin Port Co.Ltd(600717) bonded area has achieved initial results. Next, the Urban Environmental Protection Bureau of the free trade zone will continue to focus on the prevention and control of flying catkins in the near future, increase the frequency of mechanical operation in the sections where flying catkins are easy to occur, maintain round the clock patrol cleaning, supplemented by manual cleaning, so as to clean up as soon as they fall. In case of windy and dusty weather, sprinkle water on Jiada road and reduce dust by fog gun truck, reduce the impact of floating dust on citizens' travel, effectively improve the happiness and satisfaction of regional people, and strive to build Tianjin Port Co.Ltd(600717) free trade zone into an international ecological and dynamic new city suitable for Industry and residence.
