Reporter Fu Qiyuan Ji'nan news report (reporter Ren Xiufang) is affected by the risk of safety and serious diseases and insect pests caused by the dry branches of the branch, and the garden Bureau of Ji'nan City Central District plans to replace the 92 trees of Populus tomentosa in the area of the area. It is reported that 92 trees of Populus tomentosa change trees, in addition to the one road and the provincial Party committee at the gate of the 32 plants will be changed to 15 centimeters of ginkgo, the other will be changed to 13 cm of the fast birth of the Dabin.
it is understood that the City Central Garden Bureau has planned to replace 92 plants of Populus tomentosa, of which 35 are located in the small square at the north gate of the hero mountain. 32 are distributed on the road of Wei Yi (between ten roads and seven roads) and the entrance of the provincial Party Committee, and the other 25 are opposite the Ji'nan building. Zuo Ying, deputy director of the Central District Garden Bureau, said that the life span of Populus tomentosa was between 40 and 60 years. Most of these poplars were planted in the 50s and 60s of last century, and the seedlings were calculated in the age of 5 years, and they have entered the aging stage. Zuo Ying told reporters that there are two main symptoms of the aging of Populus tomentosa: a serious disease and insect pest, although the prevention and control of every year, but because of low immunity, the phenomenon is very common. Another symptom is that, due to aging of trees, dry branches increase. Windy and rainy weather brings many hidden dangers to the public and vehicles. People question one: it is not easy to repair the tree. The landscape value and ecological value have not been changed. The section and area of the more concentrated Populus tomentosa include Ma On Shan Road, heroic mountain road, weft two road, hero mountain square, and so on. Most of them were planted in the 50s and 60s of last century. Although Populus tomentosa has the shortcomings of poplar, easy to recruit diseases and insect pests, and is not easy to prune, but in Ji'nan they create a boulevard. City Central Park Bureau official said that by the growth of life, these white poplar are being replaced sooner or later.
is it necessary for Mao Bai Yang to withdraw from Ji'nan's historical stage? Ji'nan city garden expert Suo QUIN Lin told reporters that the best quality of Populus tomentosa varieties, if the growth environment is very good, 100 years of growth should be no problem, most of the growth life is sixty or seventy years, Ji'nan city of white poplar, due to the influence of underground pipeline construction and other factors, part of the phenomenon of premature failure, mainly manifested as dry roof . Suo Quinlin said that the more not to replace the white poplar depends on the two conditions: the landscape value and ecological value are already no longer, neither can form a beautiful landscape, for people to shade sunscreen, and can not absorb carbon dioxide, then it is necessary to replace. Question two: when the new plant is planted in the shade garden Bureau: from 3 to 5 years, some of the boulevards that can be counted by the citizens are related to the white poplar, such as the Eastern Road of the culture, the west culture Road, the Ma On Shan Road, the heroic mountain road, the weft two road and so on, all of which are mixed with Mao Bai and poplar. Especially in summer, the shade effect is very obvious. The tree species change, many people doubt: when can the new planted seedlings form a green shade effect?
will be replaced by the tung tree and ginkgo, the garden expert Suo quill believes that the ginkgo tree is long, but the branches and leaves are relatively sparse, and can be pruned to create landscape and shade effects. These two trees have the advantages of big crown and obvious shade effect.
