About 180 million years ago, it was the most prosperous plant on Earth, and like the dinosaurs, it belonged to the two major symbols of the "reptile" era. But after a long period of geological change, most of the earth's alders have been killed, and only a very few places called "sanctuaries" can be traced. And Quetzalcoatl, the spokesperson from ancient times, is now facing a situation of losing his voice due to multiple dangerous attacks by natural people.
There is such a plant, it seems to be flapping its wings, it is even more divine when cut open, each slice is like being painted with makeup, like a face, and like the head of a shaman, the magic is amazing, it is the keel wind, an ancient and mysterious existence.
Keel Wind, Fairy Wind Keel is ancient and mysterious
<h2 class="pgc-h-arrow-right" > keel wind, mysterious quadratic</h2>
Keel wind is the stem of the quercus plant of the family Quercus, also known as the Great Coronation and flying cockroaches. The keel wind stem is cylindrical or flat cylindrical in diameter of 6 to 12 cm, the surface is tan or black brown, often attached to dense adventitious root breaks and large petiole marks, each petiole mark is nearly round or oval, about 4 cm in diameter, there is a depression below, there are mostly tightly arranged leaf trace vascular bundles at the edges, and there are also leaf trace vascular bundles scattered in the middle.
The hard section of the keel is often hollow, and the surrounding vascular bundles are arranged in a folded shape, forming a raised ridge and longitudinal groove. Keel wind is a subtropical plant, mainly growing at an altitude of 100-1000 m in the grass under the creek or under the broad-leaved forest. It is mainly distributed in southwest China and Fujian, Taiwan, Guangdong, Guangxi, Tibet and other places. For the north, the keel wind with strange appearance is rare.
Keel is mild, bitter and astringent, has a very high medicinal value, and the medicinal part is the heart in the main trunk, when people cut the main trunk, there will be many beautiful patterns in its section, like drawing with a pen, very much like the face of the Sichuan dramatic change, and like a two-dimensional image.
Keel wind, will change the face to indulge in the second dimension
In the folk, people often use keel wind to brew wine, strengthen the body while also treating rheumatoid arthritis and other symptoms, and in traditional Chinese medicine, people use it to treat kidney weakness and low back pain, wind and fire toothache, cough, asthma and other symptoms.
<h2 class= "pgc-h-arrow-right" > keel wind, from the ancient call</h2>
When it comes to keel wind, we have to talk about its mother's womb, the alder.
It is a relict plant that originated from ancient glaciers and has only survived and thrived in some suitable ecological environments at low latitudes. Enjoying the reputation of "the king of ferns" and "living fossils" of plants, the alder is extremely precious and is a national treasure.
Quercus is one of the very few woody tree-like ferns, also known as tree ferns, water alders, stingrays, corons, keel winds, horse chestnut trees, alder trees are semi-negative tree species, like warm and humid climates, often grown in mountain streams or sparse forests, in China from 18.5 ° -30.5 ° north latitude have alder distribution, mainly produced in Chinese mainland Tibet Guizhou Chishui and southern parts, in Nepal, India Sikkim, Bhutan, India, Myanmar, Thailand, Vietnam, the Philippines and southern Japan are also distributed.
The northernmost distribution of Quercus chinensis in China is recorded as Linshui County, Sichuan, which is located in the eastern part of the Sichuan Basin, which belongs to the subtropical humid monsoon climate, affected by the terrain, the climate is about 2-4 °C higher than that of the middle and lower reaches of the Yangtze River at the same latitude, with warm winter, spring drought, summer heat, autumn rain, high humidity, more clouds, less sunshine, dry and wet seasons, etc., and the soil is mostly acidic.
The alder plant is tall, generally 3-5 meters tall, the highest is nearly 10 meters, and the chest diameter is 10-20 cm. Generally, the trunk is not branched, and the leaves are shaped like giant umbrellas and canopy trees with beautiful evergreens.
The antiquity and degeneracy of quercus quercus makes it naturally have irreplaceable and important value in the study of the formation of species and plant geographical fauna, and the coexistence of alder and dinosaur fossils has important reference value in reproducing the paleo-ecological environment of the dinosaur life period, studying the rise and fall of dinosaurs, and geological changes.
All the plants of the family Quercus are national second-level protected plants, many of which have been listed as national first-class protected plants, protected by law, and it is strictly forbidden for individuals to dig up alder.
National treasure living fossils, flying dragons in the sky
The main taxonomic features of the family Cyprinidae are scales at the base of the petiole, air bladder bodies on the leaf axis, number of spores of sporangia and sporangia lids. There are more than 500 species in 6 genera in the world, according to the current authoritative research results, There are 2 genera, 14 species and 2 varieties in China, distributed in southwest china and south China.
In China, the genus is also known as the wood tree, the subgenus of the subgenus and the subgenus of the black alder tree includes: alder sand tree, Chinese alder tree, Nanyang alder, yin sheng querce, Lanyu pen tube tree, black alder tree It is a large-leaved black-leaved tree, a large-leaf black-leaved black-sycamore (large-leaved black-leaved black-sycamore, a multi-veined black alder), a coarse-toothed alder, a black-pitched alder (a small black alder, a light-leaved small black alder), a west asian alder.
Although it has gone through vicissitudes but survived all its lives, it is still tall and tall with its stems and leaves, standing tall and tall like an ancient and mysterious work of art, and has a high horticultural ornamental value.
Due to geological changes and climate change, especially the impact of the Quaternary ice age, coupled with the destruction of a large number of forests, the species of Quercus alder is on the verge of extinction, and the distribution area has also shrunk significantly, and only tropical and subtropical remains.
Having experienced countless vicissitudes, due to human logging or natural death, the number of extant beings has been very rare, coupled with the destruction of a large number of forests, resulting in the natural environment on which the alder tree depends for survival has become more and more harsh, natural reproduction is becoming more and more difficult, and the number of alder is even smaller and smaller, and it is in an endangered state. The "evacuation" behavior in the fragile environment of the alder has aroused the attention and anxiety of national botanists and people of insight from all walks of life.
Human Elf: Please save me
The reasons for the endangerment of quercus are mainly from both themselves and the outside world.
1. Although the number of spores produced by adult strains is large, there are also many deaths. In nature, the process from germination to the formation of juvenile sporozoites takes at least 1 year or more, and changes in ecological factors such as humidity and temperature may affect the survival of germinated spores or delay the development process of later generation.
2, the process of spores germination, the formation of gametophyte embryos and other processes have strict environmental requirements, the development of alder has a serious dependence on the environment, limiting it can only live and reproduce in a certain isolated area, adult plants in the surrounding 5 meters also limit the growth of alder seedlings, so the suitable growth area is smaller. Although it occasionally invades and survives new forest areas, it does not compete with the rapidly growing plants of the region.
3, alder is the nature of woody plants, so that its reproductive cycle is very long, and its reproductive process in the case of in vitro, the development process is completely controlled by the changing environment, is not conducive to survival and development.
In addition, there is no perfect root system in the alder, and it is difficult to adapt to the existing ecological environment with great changes. As primary forests are destroyed year by year, the warm, moist, shaded, well-hydrated, soil-rich and well-drained environment on which alder trees depend is destroyed or disappears, and the alder itself is threatened or destroyed.
4. Man-made indiscriminate logging has destroyed the alder that has grown for several years or decades, and the phenomenon of illegal elements stealing and selling the alder also occurs from time to time.
If one day I disappear...
About 180 million years ago, it was the most prosperous plant on Earth, and like the dinosaurs, it belonged to the two major symbols of the "reptile" era. But after a long period of geological change, most of the earth's alders have been killed, and only a very few places called "sanctuaries" can be traced. And the spokesperson from ancient times, due to the multiple dangerous attacks of natural people, is facing the situation of losing its voice, so we must protect this call from ancient times, and do not let it only become a memory and be preserved in photos.
<h2 class= "pgc-h-arrow-right" > the tree, challenging Zhang Guolao's naughty god tree</h2>
Legend has it that in order to build a house, Zhang Guolao, one of the Eight Immortals, flew to the Moon Mountain to cut down building materials. Zhang Guolao selected all the tree groups and saw one of the sacred trees. But I didn't expect that this tree was extremely powerful, and Zhang Guolao cut down the whole day, and only cut out a hole in the trunk.
Who would have thought that after Zhang Guolao slept and woke up the next day, the mouth that had been cut down was automatically healed, and the day's efforts were in vain, Zhang Guolao was not convinced and did not believe in this evil, but after several days of sweating like rain, Zhang Guolao did not even cut down a tree.
Zhang Guolao pondered a plan, after cutting down trees during the day, he simply put the axe in the cut mouth and did not take it out at night. I thought that I could always cut down a tree with the accumulation of time, but I didn't expect that the next day when I woke up, something that Made Zhang Guolao unbearable happened, and the "wound" of the tree not only healed correctly, but also swallowed Zhang Guolao's axe and could no longer take it out.
This naughty god tree that bravely challenges Zhang Guolao's patience is the alder tree, which is said to have grown in the sky first, because it belongs to the sacred tree, and because it challenges Zhang Guolao is an interesting deed, it is called the "Immortal Tree".
Not only is it "not old", its alias is also quite a bit of posture, of which the strongest aura is the keel wind, the dragon's wind bone has it, how to listen to how is a flying posture ah.
