Pinus bungeana has the following characteristics:
First, advantages of Pinus bungeana.
1, with strong ability to absorb smoke and dust pollution, specifically for PM2.5
What is the perfect display of Pinus bungeana? Prosperous? It has many branches. Different from other pine trees, it does not grow alone from childhood, but in clusters. Generally, this long method appears on small shrubs, but it is different? It can grow into a towering tree, even for thousands of years.
Perhaps because of its structure, its absorption of smoke and carbon dioxide is among the best in garden plants. Compared with ordinary tree species, its absorption of PM2.5 is even several times.
2, evergreen, cold-resistant, drought-resistant, commonly used tree species in greening projects.
Pinus bungeana is a coniferous forest with all the evergreen and drought-resistant characteristics of coniferous forest. The weather in the north is dry, and its drought resistance is the reason for choosing it as a greening plant.
Pinus bungeana is distributed in Taihang Mountain in Shanxi, Qinling Mountain in Shaanxi and parts of western Henan, and has the largest origin and trading market in Lantian County, Shaanxi Province.
2. Seedling raising and afforestation of Pinus bungeana.
1, seedling identification and seedling raising.
To raise seedlings, we must first recognize them. Generally speaking, Pinus bungeana is similar to Pinus tabulaeformis and Pinus armandii when I was a child. Therefore, we must learn to distinguish and identify clearly when raising seedlings, so as to ensure the accuracy of breeding. Their most obvious feature is to rely on needles, and pine needles are the most direct way to distinguish these three pine trees. What is the formula? Two oils, three whites and five Huashan mountains? .
2. 1-3-year-old seedlings are pruned.
Pruning is also needed. It needs to prune the first layer of branches, that is, the layer within 20-25 cm from the ground, and the second layer does not need pruning, which is different from other pine trees. What if it is excessive? Trim? Will it grow bigger and bigger? Slim? When you grow taller, there will be fewer and fewer branches and leaves, which is an irreversible process.
3. Whole tree transplantation of Pinus bungeana.
When dealing with Pinus bungeana, some of them were actually transplanted from the whole tree. Many parks and gardens do not directly raise seedlings, but directly choose to transplant the whole tree of Pinus bungeana for 6-8 years. In the process of transplantation, it is extremely easy to survive if it is not in cold areas.
In the north or high altitude areas, Pinus bungeana may have yellow leaves or fallen leaves, but the lateral branches and roots are developed and the branches also have new buds. If the yellow leaf period is late summer, some gardeners may not care too much. It's too late after late autumn. In the cold weather in the north, it is impossible to carry. After the second year, Pinus bungeana will not live. This reason is caused by the fracture or necrosis of the apical root, and rooting powder can be saved.
4. grafting of Pinus bungeana.
Today's Pinus bungeana is somewhat different from the thousand-year-old tree Pinus bungeana. There are only a few generations of seedlings of the varieties being planted. If you need more retro Pinus bungeana, you need to graft the tender branches of ancient trees on the aged (about 5 years) rootstock of Pinus tabulaeformis. Under the operation of skilled veterans, the survival rate is still above 80%. For beginners, it is suggested to practice with other tree species first.
Generally speaking, Pinus bungeana is quite useful to society, regardless of its various representative meanings.
