Cryptomeria argyrophylla, whose subject name is Cryptomeria argyrophylla, is a rare tree species unique to China in the world. Together with Metasequoia glyptostroboides and Ginkgo biloba, it is known as the "national treasure" in the plant world. As early as the Cenozoic tertiary in geological period, Cathaya argyrophylla was widely distributed in Eurasia in the northern hemisphere, and its fossils were found in Germany, Poland, France and the former Soviet Union. However, 2-3 million years ago, a large number of glaciers appeared on the earth. Rare plants such as Metasequoia glyptostroboides, Metasequoia glyptostroboides and Ginkgo biloba have thus been preserved and become the witness of history. When Metasequoia glyptostroboides was first discovered in China, like Metasequoia glyptostroboides, it caused a great sensation in the world plant community. It was the summer of 1955. Zhong, a botanist from China, led an investigation team to the Huaping forest area in Longsheng, near Guilin, Guangxi, and found a seedling shaped like Taxodium ascendens. Later, he collected a complete tree specimen. He gave these precious specimens to Professor Chen Huanyong and Professor Kuang Keren. After their identification, he thought it was a rare plant that had long been extinct on the earth, and now only the fossil-Taxodium ascendens has been preserved. In 1950s, Cryptomeria fortunei was small in number and area. Since 1979, more than 10 plants have been found in Hunan, Sichuan and Guizhou.
Cryptomeria fortunei is an evergreen tree of Pinaceae. Its trunk is straight, tall and beautiful, with dense branches and leaves. Especially, there are two silvery white pores on the back of the green linear blade. Whenever the breeze blows, it is silvery and more attractive, and the reputation of Cryptomeria comes from it!
Distributed in Guangxi (Longsheng and Jinxiu), Hunan (Xinning to Chengbu, Zixing and Guidong), Sichuan (Nanchuan and Wulong) and Guizhou (Daozhen and Tongzi).
Brief introduction of silver cedar
Cryptomeria fortunei: The bark is dark gray. The big branches are flat, the upper end of branchlets is thick, or a few lateral branches are small and spaced. The leaf pillow is nearly strip-shaped, slightly convex, with nearly round, round or nearly square leaf scars at the top, and the color is lighter. The leaves are strip-shaped, more or less sickle-shaped, curved or straight, the apex is round, the base narrows into an inconspicuous petiole, the upper part is dark green, sparsely hairy, and there are dense brown short hairs along the concave midvein. The male flowers are oval and oval before opening, and they are spike-shaped and cylindrical when flowering, and they are nearly sessile. Bracts around the base are semitransparent and membranous, with convex back, irregular serrations at the edges, yellow stamens, female flowers without bracts at the base, oval or oblong, pearl scales nearly round or kidney-shaped, yellow-green, bract scales yellowish brown, triangular oblate or triangular oval, caudate tips at the apex, and irregular edges. The cone is green before ripening, and turns from chestnut to dark brown when ripening, oval, oblong or oblong, nearly round or oblate to ovoid, and the back is densely covered with slightly transparent pilose; The seeds are slightly flat, obliquely obovate, pointed at the base, olive green with dark green stripes, with irregular light markings, and the seed wings are membranous, yellowish brown, asymmetrical oblong or elliptic obovate. This is a rare tree species, which is a specialty of China. It was born in some mountainous areas with an altitude of 940~ 1870 meters, such as broad-leaved forests and ridge areas. Distributed in Guangxi, Hunan, Chongqing, Hubei, Guizhou and other places in China. (Overview picture 1)
What's the use of silver fir
Breeding with seeds, the silver fir is monoecious, and the male cones are usually solitary in the axils of two-year-old branches; Female cones are solitary in the axils of the branches of the current year. The cones mature after two years and are oval. Mature cones were harvested in June and 5438+ 10, and dried in a ventilated place. After the seeds fall off, the wings are ground off, mixed with wet sand and stored until the next spring.
What is a silver fir tree?
Cryptomeria fortunei (scientific name: Cryptomeria fortunei) is a genus of Pinaceae (Latin for Cryptomeria fortunei). It is a rare tree species unique to China since the Quaternary Glacier three million years ago. Together with Metasequoia glyptostroboides and Ginkgo biloba, it is known as the "national treasure" in the plant world and is a national first-class protected plant. Cryptomeria fortunei is an evergreen tree of Pinaceae. Its trunk is straight, tall and beautiful, with dense branches and leaves, which can reach 24 meters, and its DBH is usually 40 cm, and some can reach 80 cm. The leaves are spirally arranged, scattered radially, and closely arranged at the upper ends of branchlets in clusters and lines. Ginkgo biloba is monoecious, and the male cones are usually solitary in the axils of two-year-old branches; Female cones are solitary in the axils of the branches of the current year. The cones mature after two years and are oval. Known as the "living fossil" in plants.

[Edit this paragraph]
As early as the Cenozoic Tertiary geological period, Cathaya argyrophylla was widely distributed in Eurasia in the northern hemisphere, and its fossils were found in Germany, Poland, France and the former Soviet Union. However, 2-3 million years ago, the earth was covered by a large number of glaciers, which almost swept across Europe and North America. However, the glacier power in Eurasia is not great, and some areas with unique geographical environment have not been attacked by glaciers and become safe havens for some creatures. Rare plants such as Metasequoia glyptostroboides, Metasequoia glyptostroboides and Ginkgo biloba have thus been preserved and become the witness of history. When Metasequoia glyptostroboides was first discovered in China, like Metasequoia glyptostroboides, it caused a great sensation in the world plant community. It was the summer of 1955. Zhong, a botanist from China, led an investigation team to the Huaping forest area in Longsheng, near Guilin, Guangxi, and found a seedling shaped like Taxodium ascendens. Later, he collected a complete tree specimen. He gave these precious specimens to Professor Chen Huanyong and Professor Kuang Keren. After their identification, he thought it was a rare plant that had long been extinct on the earth, and now only the fossil-Taxodium ascendens has been preserved. In 1950s, Cryptomeria fortunei was small in number and area. Since 1979, more than 10 plants have been found in Hunan, Sichuan and Guizhou.
Cryptomeria fortunei is an evergreen tree of Pinaceae. Its trunk is straight, tall and beautiful, with dense branches and leaves. Especially, there are two silvery white pores on the back of the green linear blade. Whenever the breeze blows, it is silvery and more attractive, and the reputation of Cryptomeria comes from it!
What color is the silver cedar color?
The Latin scientific name is Cathaya Argyropylla Chu-Nefkuany. Among the Latin scientific names commonly used in botany in the world, the scientific name of Cryptomeria fortunei has two meanings: Cathaya is the general name of Cryptomeria, and Chinese is the ancient abbreviation of "Huaxia" China. Argyrophy-lla is a kind of silver cedar, which means "silver leaf" in Chinese. This Latin scientific name means: 1. Cryptomeria fortunei discovered in China is the only surviving genus in the world, and it is only distributed in China at present. 2. China is the "kingdom" of plants with the richest plant species and the oldest remaining species in the world, and the silver fir is the symbol of this "kingdom". Cryptomeria fortunei is the national treasure of China. 4. Cryptomeria fortunei has its unique morphological structure. 1957, Professor Chen Huanyong read a paper entitled "On the New Genus of Taxodium of Pinaceae in Western China" at the annual meeting of Soviet Botany, and it was officially published in Soviet Botany Journal on 1958. Taxodium ascendens was popular in the biological world for a while, causing strong repercussions in the plant world, and Taxodium ascendens became the patriarch of the green kingdom. The discovery of Cryptomeria Huaping has added new endemic species to the green treasure house of China, and enriched the flora of China, the subtropical coniferous forest group and the vertical belt spectrum series of forest belts. It provides living materials for the study of botany, geography, geology, paleontology, meteorology and forestry in China.
Information about silver cedar
Ginkgo biloba, called "plant panda" by botanists, is a rare treasure left over from Quaternary glaciers three million years ago. The insurance company of Chengbu Miao Autonomous County in Hunan Province has provided fire insurance for Yinshan.
There are 58 silver sequoias in Shazhoudong Silver Sequoia Nature Reserve in Chengbu County, which are rare at home and abroad. Although these "national treasures" have been listed as national first-class tree species, they are especially cherished and protected. However, because Cryptomeria fortunei always grows in dense virgin forest areas and is threatened by forest fires at any time, forestry researchers are very worried about this.
With the active support and close cooperation of the forestry department, Chengbu County Insurance Company conducted a feasibility investigation in this area, formulated relevant face-saving clauses and corresponding insurance measures, and insured 58 silver fir trees against fire.
Growth habit of Cryptomeria fortunei
Cryptomeria fortunei needs some light for its growth, but there are generally several to 20 trees in the forest, and some of them are only 1 tree, which is easily blocked by fast-growing broad-leaved trees, resulting in the death of seedlings and young trees and affecting the growth and development of trees. If no protective measures are taken, it will be replaced by fast-growing broad-leaved trees and be in danger of extinction. Flowering and pollination in May, fertilization in June of the following year, and cone 10 maturity. The cones are ovoid, light brown or greenish brown. The seeds are dark green. China is the only relic species. Cryptomeria fortunei is located in a humid climate, with an average annual temperature of 8.4- 14.8℃. Foggy, with an annual average relative humidity of over 80%, was born in some mountainous areas in the Zhongshan belt. The climate of origin is cool in summer and cold in winter, with heavy rainfall, high humidity and cloudy weather. The soil is yellow soil, yellow brown soil or yellow calcareous soil developed from limestone, shale and sandstone, and the pH value is 3.5-6.0. The soil layer is shallow and gravel. Positive tree species, with developed roots, are mostly born in narrow ridges with shallow soil and shallow rocks, usually only 2-3 meters wide, with steep slopes of 60-70 degrees on both sides, or at the top of isolated hat-shaped stone mountains or between hanging cliffs. Light-loving, fog-loving, cold-resistant, low temperature-15℃, drought-resistant, barren soil-resistant, wind-resistant, and seedlings need shade.
The main value of silver fir
Cryptomeria fortunei is an ancient relict plant whose pollen is found in tertiary sediments of Eurasia. Its special morphology and embryonic development are similar to those of Pinaceae, which is of great scientific value for studying the phylogeny, paleoflora, paleogeography and Quaternary glacial climate of Pinaceae. At the same time, Cryptomeria fortunei is also an excellent timber tree species. Its material is hard and delicate, and it is the best material for making furniture.
What does the name Zhang Yinshan mean?
First of all, I hope everyone can see that the data of the silver cedar is a tall evergreen gymnosperm with two stomatal bands on the back of linear leaves, which is named after the stomatal hairs are silver in the sun. Cryptomeria fortunei is difficult to reproduce and grows in mountainous areas of Guangxi Zhuang Autonomous Region, Guizhou Province and Sichuan Province. Its number is very small, only a few thousand, so it is called' giant panda in plants'. It is a national first-class protected plant. Yinshan
Cryptomeria fortunei is an ancient relict plant. In the Latin scientific name of plant taxonomy, the genus name of Cryptomeria, translated into Chinese, means "Huaxia", the ancient name of Greater China. Two million years ago, Cryptomeria fortunei was widely distributed in Eurasia. Since it was destroyed by Quaternary glaciers, people can only explore it with plant fossils. 1955 In May, scientists in China discovered a strange tree in Huaping, Guangxi, which looked like a pine tree rather than a pine tree. Appraised by relevant experts, it is a living specimen of the precious tree species-Cryptomeria fortunei, which is considered extinct by foreign scientists. Taxodium ascendens is a Pinaceae plant. Its trunk is generally about 20 meters high and its DBH is over 40 cm. Beautiful branches are divided into long branches and short branches, and young leaves have eyelashes at the edges. Surprisingly, there are two pink pores on the back of the green leaves, and the leaves full of dew are shining silver in the sun, hence the name "Silver fir". Silver fir trees are very precious. Parents hope that this child can be as tall, evergreen and promising as a silver fir tree. And parents compare their children to silver fir trees, which proves that these parents attach great importance to their children! That's what I understand! ~
