It's raining with frost, and its cuiyu blue tip is two thousands of feet in the sky.
Since the era of a great ruler and great politician, their trees are now loved and respected by the people.
Clouds come from afar, from Wuya, and the snow peaks are reflected in the cold moon.
Yesterday I found in the east of Siting that ancient rulers and wise politicians were worshipping in a temple.
His trees and strange branches make the whole landscape old, although the colors of windows and doors are fresh.
The deep roots are so firmly rooted in the ground that its lonely branches can withstand the weight of the wind.
Its only protection, honesty, leads to the chemical industry.
When beams are needed to repair a big house, although cows shake their heads, they can't move a mountain.
Although a tree doesn't write a memorial, people understand that if you don't stop cutting, who will give it to you?
Its bitter heart may now be occupied by black ants and white ants, but its scented leaves used to be the nests of phoenixes and pheasants.
Wise and hopeful people should not be dissatisfied: the bigger the wood, the harder it is to use.
Understand Yi Song.

9. Poems about pine trees ask for help to edit encyclopedia business cards, pine trees and evergreen trees.
Most of them are tall trees. It is 20~50 meters high and can reach 75 meters at the highest (P.lambertiana, American sugar pine).
A few are shrub-like, such as dwarf pine and Yunnan pine. Pines are wheel-shaped branches with long internodes, thin and flat branchlets or slightly bent downward, and needles are slender in bundles.
So its crown looks loose but not compact, and the word "loose" is an image description of its crown characteristics. So "pine" is a tree with a loose crown.
Pine trees are strong and will not die all year round. This paper briefly introduces the morphological characteristics of pine trees, the distribution types of pine trees, the requirements for climatic conditions and pine tree distribution, the requirements for shade tolerance and tree species replacement, drought resistance, reproduction, flowering, fruiting and development, the variability of trees, ornamental applications, the maintenance of wood and other products and the medical value of the oldest pine trees, the research results of pine products in the medical field, the treatment methods of common diseases by folk traditional pine trees and the therapeutic effects on pine trees. Morphological characteristics of pine trees, distribution types of pine trees, requirements for climatic conditions and distribution of pine trees, requirements for shade tolerance and tree species replacement, drought resistance, propagation, flowering, fruiting, growth and development, variability of trees, ornamental application, conservation of wood and other products, and medicinal value of the oldest pine trees with diseases and insect pests. The medical research results on pine products comment on the curative effect of folk traditional pine therapy on common pine diseases. The introduction of this pine tree is called: Pine tree Huangshan pine is world-famous (20 pieces). Scientific name: Pinaceae: Pinaceae Pinus: Forest Tree-Conifer Medicine: Pine has high medicinal value and can be used as medicine in all parts of the body.
Edit the morphological characteristics of this part. When young trees are young, the crown is pyramid-shaped and the branches are mostly wheel-shaped.
When the seedlings are unearthed and the cotyledons are unfolded, the primary leaves appear first, which are solitary, spirally arranged, linear and lanceolate, and the leaf margin is toothed. It takes 1~3 years for primary leaves to function as leaves, and then there are needles, usually 2, 3 or 5 bundles, which are inserted at the top of short branches.
Each bundle of needles has a leaf sheath at the base, which falls off or exists early. The position of resin channel in mesophyll tissue is relatively constant in adult plants, which can be divided into three types: exogenous, mesophyll and endogenous.
There are 1 or 2 vascular bundles in the cross section of pine needles, and the vascular bundles can be combined in the double vascular bundle pine under special circumstances. These cones are monoecious and monoecious.
Most cones are composed of seed scales and lignified when they mature. The exposed and thickened part of the seed scale is called the scale shield, and the tumor-like process at the top of the scale shield is called the scale navel.
Some tree species have thorns on their scales and umbilicus, while others don't. When the cone is mature, the seed scales open and the seeds fall off; But the scales of some trees remain closed for a long time.
Each seed scale has 2 seeds, the upper part has long wings, and a few have short wings or no wings. Korean pine, Pinaceae, is the largest family of gymnosperms, with more than 230 species of 10 genus, including more than 90 species of Pinus, which is the largest genus of Pinaceae and even the whole gymnosperms.
Pine is the most important forest tree species in the northern hemisphere. Except for the black pine distributed at 2 degrees south latitude, other species naturally grow on the Yuan Ye, a mountain and river from the equator to 72 degrees north latitude. Especially in temperate regions, pine trees are not only varied, but also often form vast forests, so pine trees are known as "the mother of forests in the northern hemisphere".
Pine trees are very adaptable to the land environment. They can tolerate the low temperature of -60℃ or the high temperature of 50℃, can grow in bare mineral soil, sandy soil, volcanic ash, calcareous soil, limestone soil and various soils from calcareous soil to red soil, and are drought-tolerant, barren and sunny, so they are famous pioneer trees.
The most obvious feature of pine trees is that their leaves are needle-shaped, usually in bundles of 2, 3 or 5 needles. For example, the leaves of Pinus tabulaeformis, Pinus massoniana and Pinus taiwanensis are in bundles of 2 needles, the leaves of Pinus bungeana are in bundles of 3 needles, and the leaves of Pinus koraiensis, Pinus armandii and Pinus pentaphylla are in bundles of 5 needles.
Pine is a monoecious plant, and its spore leaves are arranged like cones, forming female cones and male cones. Single or 2 14 female cones are attached to the top of new branches, and most male cones gather in the lower part of new branches.
Pine cones usually bloom in spring and summer, but after the pollen reaches the female cones, it will not germinate until the early summer of the following year, so that the female flowers will fertilize and develop into cones (commonly known as pinecones or cones, not fruits). The cones mature after autumn, and the seed scales open, and each seed scale has two seeds.
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.
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 peaks and pine trees.
Huangshan pine in Huangshan, Huashan pine in Huashan and Meiren pine in Changbai Mountain ... all amaze tourists. China is one of the countries with the richest gymnosperms in the world. From the perspective of Pinaceae, it can be fully explained that China is a veritable "hometown of gymnosperms".
In China's vast mountainous Yuan Ye, there are not only lush pine, larch, spruce and fir forests, but also many extremely precious and rare Pinaceae trees hidden in some deep mountains and forests. Among the first batch of rare and endangered plants under special state protection, there are 39 species of Pinaceae, accounting for110 of the total (389 species).
Among them, Cryptomeria fortunei is listed as the first-class key protected plants, Abies baishanzu and Pinus yunnanensis 17 species are listed as the second-class key protected plants, and Taxodium mexicana and Pinus sylvestris var. mongolica/0 species are listed as the third-class key protected plants. Twenty years ago, few people in the world knew that there was a mountain called baishanzu on the southeast coast of China.
During the period of 1976, Wu Yiming, a senior engineer of Zhejiang qingyuan county Forestry Institute, made a blockbuster. The Baishanzu Abies discovered and named by him made baishanzu, a "forgotten corner", shine brilliantly in the field of world botany. 50 known species in the world.
