Wood is used to make musical instruments and furniture; Bark fiber can be used to make paper; Seeds are fried for food and squeezed for making soap and lubricating oil. And is helpful for greening.
But in Changchun, the climate is not suitable, and survival is a problem. Tung oil tree belongs to the southern tree species. It can survive in Tianjin, but it will be miserable in the northeast. It is better to buy paulownia or paulownia. I studied gardening and asked the nursery for bronze. I don't think there is any here.

The tree has a tall trunk, lush foliage, rapid growth, easy survival and pruning resistance, so it is widely planted as a street greening tree species and a fast-growing timber tree species. It has strong resistance to toxic gases such as sulfur dioxide and chlorine.
Platanus acerifolia grows fast and its wood is loose. Because of its fleshy roots, it is afraid of freezing injury, flooding, diseases, virus diseases and insect pests. Its roots are thick and shallow and windy.
Indus loves light. Like warm climate, not cold-resistant. Suitable for fertile, moist sandy loam, such as alkali. Roots are fleshy, water-resistant, deep and thick; The germination ability is weak, so it is generally not suitable for pruning. It grows fast and has a long life span, and can live 100 years. In the growing season, the roots rot and die after being flooded for 3 ~ 5 days. Leaves grow late and fall early in autumn. It has strong resistance to a variety of toxic gases.
Wu Tong, also known as Qingtong, is a deciduous tree in Wu Tong. The crown is oval, the trunk is straight, the bark is green and smooth, and the lateral branches are thick and green.
Platanus acerifolia is a positive tree species that likes warm and humid climate. Widely distributed in our country, the cold tolerance is not strong. It can grow on acidic, neutral and calcareous soils. Deep-rooted, waterlogging is easy to rot roots, and waterlogging in high temperature season can kill you for 3 to 5 days. Fast growth and long life. Ye Wan's hair leaves early. Leaves, flowers, roots and seeds can all be used as medicine, and seeds can also be fried to extract oil.
Sowing propagation is commonly used, and cutting and rooting propagation can also be used. Harvest the fruit when it is ripe in autumn, dry it and thresh it, then sow it in the autumn of that year, or store it in sand until the spring of the next year. The row spacing of drilling holes is 25 cm, the thickness of covering soil is about 1.5 cm ... and the sowing amount per mu is about 15 kg. Seeds germinate regularly, 4-5 weeks after sowing. Dry-stored seeds often germinate unevenly, so they can be soaked in warm water before sowing to accelerate germination. Under normal management, the height of the seedlings in that year can reach more than 50 cm, and then they will be planted and cultivated in the next year. Three-year-old seedlings can leave the nursery. The planting place should be chosen in a high and dry place, and base fertilizer should be applied in the hole. After drying, the incision should be sealed with wax. Pay attention to pests such as Gynostemma pentaphyllum, litchi stinkbug and Hymenoptera. Can be controlled by petroleum emulsion, dichlorvos, dimethoate and methamidophos. In the north, young trees should be wrapped with straw ropes to keep out the cold in winter. Fertilize once in winter and once in early spring.
Platanus acerifolia is easy to cultivate, simple to manage and very water-saving. Lush foliage and thick green shade are legendary because of the legend of phoenix tree attracting phoenix. It is an important courtyard greening tree species in China, and it is suitable for single planting or cluster planting in lawns, courtyards, houses and slopes. Because of its strong resistance to sulfur dioxide and hydrogen fluoride, it can also be used for greening in factories and mining areas.
Recommend a method of transplanting big trees by irrigating roots and raising trees.
The story of buttonwood and phoenix
Because the phoenix tree is tall and straight, it is the crown of the tree. It has been valued since ancient times. It is often associated with the phoenix. Phoenix is the king of birds. Phoenix is most willing to inhabit the phoenix tree, which shows how noble the phoenix tree is. For example, in the Book of Songs in China, there is a record about the phoenix tree. In the elegant "volume" of the Book of Songs, there is a poem that reads:
"Feng Huangming yi, in Gorkon. The phoenix tree was born in the morning. Serving (with the word "grass") is gentle and sincere. 》
This poem is about the lush phoenix trees that make the phoenix crow. Fengfeng (prefixed by grass, the sound of collapse) is flourishing, which is the wealth of phoenix tree; Yong Yong Bo, it's the voice of Feng Ming.
In Zhuangzi's Autumn Water, I also talked about the phoenix tree. When talking about Keiko, Zhuangzi said: "There are birds in the south, and there are thousands of chicks (beside the right birds). What do you know about them? Husband than (right bird) chicks, originated in, flying in the North Sea, not just phoenix tree, ... "
In this article, the phoenix is also associated with the phoenix, and the "ten thousand chicks (beside the right bird)" here is a kind of phoenix. He said that the phoenix flew from the South China Sea to the North Sea, and only the phoenix tree fell. It can be seen that the phoenix tree is noble.
In the thirty-seventh chapter of the Romance of the Three Kingdoms, there is such a description: "The phoenix flies thousands of miles away and does not live on the road; Master is on the side, not the Lord. "
Because the ancients often associated the phoenix with the phoenix, people now often say, "If you plant a plane tree, you will have your own phoenix." . Therefore, in the past, in a well-off family, phoenix trees were often planted in the yard, not only because of its imposing manner, but also because it was a symbol of good luck.
