Pine is a pine family, a genus of pine.

Plant. There are more than 80 species of pine trees in the world, and pine trees are mainly divided into masson pine, tabuliformis pine, whitebark pine, and podocarpus.

Huashan pine, Dabie Mountain five-needle pine, Korean pine, red pine, black pine, Huangshan pine, Yunnan pine, money pine, sylvestris pine, cedar, etc. For example, Pinus tabuliformis, Pinus sylvestris, Pinus sylvestris sylvestris and Pinus sylvestris Pinus sylvestris are distributed in North China and Northwest China, Pinus massoniana, Pinus huangshan and Pinus alpine in Central China, and Pinus bashan in Qinba Mountains.

As well as Taiwan pine and North American breviphylla pine, most of them are the main tree species in China's barren mountain afforestation. Biyou pine is a wheel-shaped branch, with long internodes, relatively thin and straight branches or slightly curved downwards, and slender needles in bundles. Its canopy looks fluffy and not compact, and the word "pine" is the image description of its canopy.

Therefore, "pine" is a type of tree with a fluffy crown. Pine trees are sturdy and have a very long lifespan.

History of Botany. Legend has it that Qin Shi Huang.

Once to Mount Tai, in the north of the current Buyun Bridge, suddenly it rained heavily, fortunately there are 2 ancient pine trees on the side of the road to hide from the rain.

Unexpectedly, in 1602 (quite Ming Wanli.

During the year) Mount Tai rained suddenly, washing away the five major doctors.

The three existing plants were replanted in 1730 A.D. (the eighth year of Yongzheng in the Qing Dynasty). But there is indeed an ancient pine on a hillside not far from the five major pine trees, which is called "Wangren pine", and the age of the tree has reached 2,300 years old, which can be called the champion of pine years.

The six dynasty pines in the Puzhao Temple of Mount Tai are already 1400 years old. In Shanxi Wutai Mountain Foguang Temple.

It is suitable for building timber, joinery, packaging materials, interior decoration, aviation equipment, bridges, furniture, sports equipment, particleboard and fiberboard, etc. It is a precious handicraft material.

1.It takes more than 15 years for a pine tree to reach maturity, but the longer it takes to grow, the better.

2.If a pine tree is mature, it needs to have a DBH of more than 20 cm, and it usually takes 15 years to grow, but it is also related to the growth environment.

3.In the first 10 years, the growth of Korean pine will be relatively slow, and by 10-30 years, the growth will reach the peak and grow rapidly.

4.Pinus tabuliformis, Pinus yunnanensis and Pinus massoniana grow faster in the early stages, but mature later.
