In recent years, with the introduction and development, many tree species have been dug out and will play an increasingly important role.
Among the deciduous trees, I prefer ceiba, which has strong adaptability, cold resistance, water resistance, drought resistance and saline alkali resistance. It can be planted from northeast to northwest. The headquarters of three North Shelterbelt has designated it as the main afforestation tree species, and it is expected to use a lot in the next few years. Gossypium can also be grafted with Hokkaido Euonymus japonicus, Euonymus japonicus, Euonymus fortunei and other evergreen trees. At present, its price has gone up. The seedling with diameter at breast height of 5cm costs 60 yuan, but there is still a big room for increase.
The second is Lianxiang tree, which has been proved to be safe in winter in Beijing. At present, Lianxiang tree planted in Beijing Botanical Garden is growing well. It is a tall tree with beautiful tree shape, leaves and good wood. It can be used as a roadside tree in the north. It is also a national first-class protected tree species and is very precious.
