Contrary to the dead red maple leaf on Tran Duy Hung Street, another tree with equally beautiful beauty is growing green in Hanoi. Mr. Le Huy Cuong, an expert of the Vietnam Association for Forestry Science and Technology, said that this is the following, a native species of Vietnam. The following trees are distributed in the northern provinces such as Lao Cai, Lang Son, Cao Bang, Ha Giang. In Hanoi, this variety is widely grown in the Ngoai Giao Doan urban area, West Lake West, the area of ​​the Korean Embassy and the regulating lake of the Exchange City urban area. The posterior leaves are shaped quite like maple leaves. According to experts, to distinguish the posterior tree and the maple tree, people rely on the leaf lobes. The posterior leaves are split into 3 lobes and the maple leaf has 5-6 lobes depending on the habitat. In the northern provinces, the young leaves of the following plants are used for food. As noted by Zing on April 6, around the area of ​​the exchanging city lake, there are more than 30 trees, the Diplomatic Corps Urban Area has about 150 trees. My Huyen (in Cau Giay, Hanoi), said she and her friends came here to take pictures because they heard that there are rows of maple trees in Korea. She was surprised to learn that this is not a red maple tree, but a native variety of Vietnam. “I will definitely come back in the fall to have pictures when the leaves change color,” she said. The posterior fruit has many soft, pointed spines. The following trees all grow green, with a trunk diameter of 20-30 cm and a height of about 6-7 m. Some trees lay new branches, and the sprouts developed green. The canopy of trees is wide, creating shade for many young people to come play and rest. “The following tree is suitable for the city because of its strong root system, which is well adapted to the environment. I asked the Hanoi Greenery Park Company to multiply and concentrated this tree, especially around lakes so that people can come to take pictures, ”said Mr. Le Huy Cuong. In the photo, the lake in Exchange City is where dozens of trees are planted. In winter, the following leaves also turn yellow, as brilliant as the red maple tree in cold countries. Photo: Nam Hai – Tran Duy Hai. The following rows of trees grow green, making many people expect European colors in the heart of Hanoi.

After 2 years of trial planting, the red leaf maple trees planted on the median strip of Nguyen Chi Thanh – Tran Duy Hung routes grew poorly or died dry due to not suitable for Hanoi’s climate.

As reported, Hanoi City People’s Committee Office has just issued Document No. 2788 / VP-DT (dated 2-4-2021) announcing the direction of Vice Chairman of the City People’s Committee Duong Duc Tuan on the replacement plan. The maple tree position is tested on the median strip of Nguyen Chi Thanh – Tran Duy Hung street.

According to Deputy Director of Hanoi Construction Department Nguyen The Cong, 262 maple trees were tested from 2018 on the median strip of Nguyen Chi Thanh – Tran Duy Hung streets, donated to the city by Tan Dai Duong Investment Joint Stock Company. After 2 years, it initially showed that the tree was not adapted to the climatic conditions of Hanoi. 45 trees died, 217 trees lived but poor growth and development. After a while, leaves are wilted, branches and branches are dry and often pests and diseases, affecting the street landscape. In order to ensure the landscape, synchronize the system of green trees, meet the aesthetic and urban beauty of the road, the Department has proposed the City People’s Committee to switch the maple tree and plant it to replace it with a small leaf almond tree.

The planting of new tree systems will be carried out in April 2021 and completed before the holidays April 30 and May 1, 2021.

Later, the tree species is easily confused with red leaf maple

Facing the fact that the red leaf maple goods on the Nguyen Chi Thanh – Tran Duy Hung route die or grow poorly due to the lack of adaptability to the climate conditions of Hanoi … some people wonder why the maple is grown at the Diplomatic Corps (Xuan Tao, Bac Tu Liem, Hanoi) is green again, in winter, trees turn red leaves beautifully?

Many people mistakenly think that the following trees after planting in the Diplomatic Corps are red-leaf maple because of their maple leaf shape and the ability to turn red in winter.

Answering the above question, Assoc.Prof.Dr. Dang Van Ha, Director of the Institute of Landscape Architecture and Urban Greenery, Forestry University affirmed that the crops grown in the Diplomatic Corps area are not red-leaf maple, but tree follows. This native species of Vietnam is being planted widely, from North to South because it has good growth and development, especially in urban areas. In Hue, the latter has been planted for a long time, many trees with a diameter of 60-70cm.

In Hanoi, in addition to the Diplomatic Corps, the latter is also grown in the West Lake, the area of ​​the Korean Embassy, ​​the regulating lake of the Exchange City urban area … The following trees are growing green. well, trunk diameter 20-30 cm, about 6-7 m high.

“The posterior leaves are shaped quite like maple leaves. In winter, they change from green to dark yellow and red, so many people easily confuse them. However, just based on the leaf lobe it is possible to distinguish 2 species. Specifically, the posterior leaves split into 3 lobes and the maple leaf has 5-6 lobes. In addition, the maple tree has no fruit, while the posterior fruit has many soft, pointed spines ”, Assoc. Analysis by Dr. Dang Van Ha.

However, according to experts, just based on the leaf and fruit lobes can easily distinguish these two plants.

According to Mr. Ha, later it can be planted well in urban areas, parks, sidewalks, medians … Trees not only have the ability to grow well, but create beautiful landscapes thanks to the characteristic turning the color of leaves to red. . Young shoots that sprout up right after the leaves fall, are also fancy pink. According to the Institute’s observations for many years, plants do not have pests and diseases affecting humans. After about 50-60 years of growth, the tree has the phenomenon of aging, so it should be noted that dry branches are pruned.

Small leaf wing, why is preferred?

According to both plans to replace the red leaf maple row on the Nguyen Chi Thanh – Tran Duy Hung route, small leaves are selected. Mr. Tran Anh Tuan, Deputy Director of the Department of Maintenance of Urban Technical Infrastructure (Department of Construction of Hanoi), said that the small leaf eagle has been experimentally planted for a long time and brings beautiful landscapes on many streets in the city. Hanoi like Dao Tan, Nguyen Khanh Toan, Kim Ma … Through monitoring, the tree grows and develops well and stably. In particular, this plant has very few pests and diseases, is less prone to breakage during storms, and does not take care of and pruning.

Small leaf balm has been planted for a long time and has adapted well, creating a beautiful landscape for Hanoi.

According to Assoc.Prof.Dr. Dang Van Ha, small leaf eagle, also known as Taiwanese eagle, is a suitable crop in urban areas as well as in many other places. Tree has the advantage of strong root system, less breakage, flexible stem and branches.

“Small leaf balm was imported abroad into our country about 20 years ago, and grown in many provinces throughout the country, including Hanoi. Plants are easy to propagate, grow well, do not pick up soil, and can be grown both in dry places and high water levels. Trees give good shade in the summer. In the southern provinces, in the dry season, the tree often loses its leaves. However, in the North, the tree also loses its leaves, but only for a short time and produces young leaves immediately. Because the small leaf almond root has “floating” properties, it should be considered when planting in narrow streets, which do not affect the quality of the pavement “, Assoc.Prof.Dr. Dang Van Ha said.

For the people of Hanoi, the rows of small green-leafed almond trees planted for many years have become familiar and captured the hearts of many people by the beautiful landscape trees. The trunk grows straight, branches grow horizontally or form to create circular, interwoven canopy, creating shade. The leaf is shiny green and gradually darkens over time, the deciduous time is very short.

There are many suitable advantages that help the small leaf eagle to be selected as a priority for urban crops.

The trial planting of new species of trees in Hanoi is completely normal in order to supplement and enrich the urban greenery system, which plays a very important role in improving and improving the quality of life for the people. However, before trials showed that new species of trees have not been adapted, the replacement with more suitable species is necessary so that the capital city always maintains green, fresh and urban beauty.
