Are you curious about the characteristics of pine trees and a simple introduction to the green plants and flowers related to their physical features? Next, the editor will introduce them to netizens.
【Introduction】:“Heavy snow presses on the green pines, which stand tall and straight.” Pine trees are towering and unyielding in people's impressions, embodying justice and fighting spirit. However, these are only some of the morphological and physiological characteristics of pine trees. To truly understand and recognize pine trees, we need to comprehensively understand their morphological characteristics, physiological features, uses, and cultivation methods.
Morphological characteristics of pine trees
Pine trees are evergreen large trees of the Pinaceae family, with a very few becoming shrubs in specific environments. They have a well-developed main root that can penetrate rocks, with sparse lateral roots; the trunk is thick and sturdy, ranging from brown to black-brown, deeply fissured, often secreting resin; branches are whorled, with one or two to three rounds per year; leaves are needle-shaped, 2 to 5 in a bundle, evergreen, with bundles pointing upwards; both flowers and fruits are spherical, unisexual flowers, with female flowers on the same plant, blooming from February to March, and fruits ripening from August to October; most pine trees grow tall and strong, enduring wind and snow, full of virility.
Physiological characteristics of pine trees
There are many species of pine trees, evenly distributed throughout China, which are drought-resistant, cold-resistant, and thin-soil-tolerant but dislike moisture. They can survive well on cliffs, hence the name "pioneer species," which can be used for soil improvement in barren mountainous areas. Pine trees are strong light plants, preferring sunlight but also having a certain degree of shade tolerance, growing best in deep, loose, fertile, and well-drained soil. Pine trees can live for thousands of years, a symbol of longevity, with the saying "pine cranes prolong life" in folklore. It is recorded that a certain ancient pine tree in Nanshan Temple, Guangxi, is over 3000 years old.
Uses and functions of pine trees
Pine trees have a wide range of uses and are treasures in themselves. First, pine trees are one of the world's three major fast-growing species, with medium-hard wood that can be used in construction and furniture, making them an important timber species; second, pine resin is an important chemical raw material used to refine pine rosin and turpentine; pine seeds, known as pine nuts, are famous dried fruits, rich in nutrients with a unique taste; pine trees are also one of the main species used in landscaping and bonsai. Moreover, pine needles and bark are excellent substrates for growing flowers, and pine cones can be used to make crafts, etc.

Key points for cultivating and planting pine trees
Pine trees have a strong adaptability and can be cultivated and planted throughout China. Cultivating pine trees requires selecting mountainous areas with good lighting conditions, deep and fertile soil, and good permeability based on the physiological characteristics of pine trees. It is also necessary to determine the appropriate initial planting density based on the growth rate of different pine trees, such as 110 plants per mu for fast-growing foreign pine and at least 333 plants per mu for slow-growing masson pine. Since pine trees have underdeveloped lateral roots and a low survival rate after planting, it is necessary to promptly replant and strengthen cultivation until the forest is closed.
【Conclusion】: Pine trees are one of the oldest tree species on Earth and one of the most widely distributed in their natural state, with strong vitality and adaptability, a wide range of uses, and deeply loved by the people. They symbolize longevity and auspiciousness in the eyes of the Chinese, and are known as the "three friends of winter" along with bamboo and plum blossoms, often celebrated in poetry, painting, and watercolor.
