Acer truncatum, also known as the color maple, is a deep-rooted deciduous large tree. Although it does not have a straight trunk, it has a beautiful tree posture. It has the ability to purify the air, absorb smoke and harmful gases, and secrete volatile bactericidal substances. The color of the leaves of Acer truncatum varies. The leaves are red when young, and turn orange or red in autumn. The leaves and flowers bloom together. It is an excellent autumn leaf tree species in the north.

In addition, the water content of the maple tree is high and the oil content is low. Its dead branches and leaves decompose quickly, which helps to quickly reduce the combustible load in the forest and change the fire environment. This shows that it is an ideal fire-resistant tree species.

Acer truncatum grows slowly, has a long lifespan, and is less susceptible to diseases and insect pests. It is highly resistant to toxicity, sulfur dioxide, and hydrogen fluoride, and has a strong dust absorption ability. It has a good foliage effect, with red young leaves, yellow, red, or purple-red autumn leaves, and beautiful leaf shapes.

It is worth noting that the stem quality of the maple is poor. If it is allowed to grow randomly, the tree shape will not be beautiful after it is formed. It is best to carry out artificial shaping and pruning before reaching the fixed stem height. But on the other hand, the stem quality of the maple is very suitable for the cultivation of natural cluster seedlings.

Beech, a tree species underestimated by the market, has outstanding advantages in terms of ornamental, ecological, and cultural aspects, rich added value, and promising prospects.

First, the value of gardens.

The beech tree has a dignified posture, is tall and majestic, and its leaves turn brown-red in autumn, making it an excellent tree species for viewing autumn leaves. It can be planted alone or in groups on lawns in parks and squares, or beside buildings as a shade tree; it can also be planted with evergreen trees to form a landscape forest.

Second, ecological value.

First, it has strong anti-pollution ability and can effectively absorb harmful gases. It can be planted as a street tree beside sidewalks and roads. Nowadays, people pay more and more attention to environmental protection, and greening conditions are one of the criteria for people to refer to when buying a house. In real estate construction, if beech trees are used, people will say "Hey, the environment is good", which will have a good impression.

Second, beech trees are deep-rooted trees with strong soil-fixing and wind-resistance capabilities, and are not easy to fall over. They can be used as street trees in coastal cities, as shelterbelt trees, and as soil and water conservation trees. In recent years, several super typhoons have swept coastal areas, and urban greening trees have fallen down due to the wind, causing serious economic losses to the local area. Deep-rooted trees are gradually beginning to receive attention.

In addition, planting trees is not only about beautifying the environment, but also about people’s understanding of plants – plant culture. “Ju” means passing the imperial examination, and ancient people often planted them in front of and behind their houses.
