There are nearly 80 kinds of pine trees in the world. Although there are many kinds, the leaves are slender and needle-shaped, commonly known as pine needles. Most needles are gathered by one or several leaves. Pine with one leaf and one needle is only distributed in Nevada and Mexico in the United States, belonging to a few varieties. Two-needle bundle of two-leaf pine is not only a wide variety, but also widely distributed, such as Pinus tabulaeformis and Pinus sylvestris var. mongolica. Pinus sylvestris var. mongolica, Pinus thunbergii and Pinus densiflora distributed in several provinces of North China and Northwest China, Pinus massoniana, Pinus taiwanensis, Pinus alpine and Pinus Bashan in Qinba Mountain area, and Pinus Taiwan Province and Pinus brevifolia in North America. Most of them are the main tree species for afforestation in barren hills in China. Three-needle and three-leaf pine includes Pinus bungeana, Pinus yunnanensis, Pinus Simao in Sichuan and Yunnan, Pinus elliottii and Pinus taeda introduced from central and southern China. A bundle of four-needle pine trees is rare and only distributed in California, USA. Besides, eggs and pine are in bundles of four or five needles. There are many kinds of pine trees with five needles in a bunch, which are widely distributed, including Korean pine in the northeast, Huashan pine, Qiao pine, Guangdong pine in the northwest and southwest provinces, Anhui five-needle pine, Dabie mountain five-needle pine, Chinese pine and Taiwan Province fruit pine. The difference of pine needles helps us to classify and identify pine trees and understand their ecological characteristics. Usually, five-needle pine is suitable for humid environment and has strict requirements on soil, while two or three-needle pine is more drought-tolerant and can grow in thin soil. For example, a bunch of Pinus tabulaeformis with two needles has strong adaptability to land climate and atmospheric drought, and of course it also sags with its needle pores. Wax on the leaf surface can reduce partial evaporation.

Functions and uses of pine trees

Ornamental value

The ornamental value of pine trees is obvious to all. In China, beautiful images of pine trees can be seen from the royal classical gardens to the homes of modern residents, such as Pinus tabulaeformis and Pinus bungeana in Beihai and Summer Palace, and Pinus pentaphylla widely used in stump bonsai. Some famous mountain resorts are famous for their majestic mountains and pine trees. Welcome pine in Huangshan Mountain, Huashan pine in Huashan Mountain and Ren Mei pine in Changbai Mountain ... all amaze tourists.

Pine trees not only have economic uses, but also have important ornamental value because of their majestic posture and long life. It is an important part of many scenic spots in China. For example, Qian Shan in Liaoning, Mount Tai in Shandong and Lushan in Jiangxi are all famous for their pine scenery. Especially in Huangshan, Anhui, pine, cloud and stone are also called "three wonders", led by pine. Many Gu Song in various places are closely related to China's long history and culture. For example, there is an 800-year-old Gu Song in Beijing Beihai and Yuanmingyuan, which is said to have been named "Yin Hou" by Qing Qianlong. The legend of Mount Tai's "Five Buddha Pines" is that Qin Shihuang went up the mountain to shelter from the rain and was given an official title. People in China regard pine trees as a symbol of firmness, chastity and longevity. Song and Zhu are also called "three friends of the old and the cold", which means the indomitable spirit of defying adversity and overcoming difficulties.

Good wood

Pinus species are mostly tall and straight trees with good materials and many columns. Korean pine, the "king of wood" in the northeast of China, tall Pinus ponderosa (up to 75 meters) widely distributed in the west of North America, the fastest growing pine radial pine originated in the coastal area of California, slash pine originated in the southeast of the United States, Caribbean pine originated in the Caribbean of America, and Pinus densiflora widely distributed in the west and north of Eurasia. , are famous timber trees.

App application

According to the structural characteristics and wood properties, pine trees are generally divided into coniferous pine and broad-leaved pine. Cork pine (that is, subgenus of single vascular bundle) is light and soft, uniform in texture, low in strength, easy to process, with gradual change from early wood to late wood and few wing cracks. Hardwood pine (that is, subgenus of double vascular bundles) is relatively hard, uneven in texture, high in strength, difficult to process, fast in transformation from early wood to late wood, and high in rosin content. However, Hainan five-needled pine and South China five-needled pine belonging to cork pine are close to hardwood pine in strength and bulk density. Pine can be used in buildings, telephone poles, sleepers, columns, bridges, farm tools, appliances, furniture and other purposes. The cellulose content of various pine trees is about 50 ~ 60%, and the lignin content is 25 ~ 30%, which is one of the important raw materials for pulp and paper industry. There are pine trees, too.

Fuelwood

Rosin and turpentine can be extracted by cutting turpentine from pine tree trunks. Pine nuts are rich in protein and oil, and the oil content is above 30%. Among them, there are 20 species with edible value, such as Korean pine, slash pine and Huashan pine, all of which are produced in China. The seeds of Korean pine can also be used as medicine, and the medicine name is "sea pine seed", which is a nourishing tonic. Pine bark and seed coat are rich in tannin, and tannin extract can be extracted by soaking. After the bark is crushed, it can be mixed with other raw materials and pressed into hard fiberboard. In addition, pine needle volatile oil can be extracted from pine needles. Needles are rich in carotene, vitamins, fat, protein, calcium, phosphorus and other mineral elements, which can be processed into feed additives for poultry and livestock. Incomplete combustion of pine branches and roots in kiln can make pine smoke (see dry distillation of wood), which can be used to make ink, ink and black paint. Pine branches and roots are also raw materials for cultivating valuable medicinal material Poria cocos.
