The Qinghai-Tibet Plateau is known as the "roof of the world", the entire altitude is more than 4,000 meters, it is in a cold state all year round, but there is a "Chinese cabbage" growing on the Sichuan-Tibet line, very beautiful, and much taller than the general cabbage, can grow to a height of 1 to 2 meters, the leaves change color from the bottom to the top, from green to yellow, and then gradually to white, bloom only once in a lifetime, the vitality is very tenacious, can survive for 10-45 years, but one thing you must know, so beautiful can only be seen and not picked, Much more precious than you think, it is a Tibetan medicine that cannot be cultivated artificially, it is a miracle of nature, do you want to know its name?
Compared with the pretentiousness of Chinese cabbage, comfortable greenhouses are not willing to stay, only willing to be in the wild mountains, this plant is called "tower yellow", in fact, it has no half a dime relationship with Chinese cabbage, tower yellow seems to grow in the wilderness, but now many are Tibetans personally breeding in the wild, belonging to private property, if there are tourists because of curiosity to pick at will, it is likely to be compensated by local Tibetans. It is the attitude of Tibetans towards Tahuang that does not make Tahuang an endangered plant. Interested friends can follow me to learn about this "Chinese cabbage" on the Sichuan-Tibet line.
Tahuang this plant will only appear on the Sichuan-Tibet line, other places do not appear, generally grow on the mountain rocky beach at an altitude of more than 4,000 meters, it is a perennial herbaceous plant, the growth cycle is extremely slow, generally 1 to 2 years long leaves, 3 to 4 years flowering, to more than 5 years to mature. Once the tower yellow has finished flowering, its lifespan has come to an end, and it will naturally shrink before long. Tahuang as a Tibetan medicine, but only suitable for wild, artificial can not be cultivated, low survival rate, but also affect the medicinal properties, so the price of sales is naturally scary, the price of a kilogram of tahuang can be sold for thousands of yuan.
How does Tahuang survive in a cold environment at high altitude? If any animal or plant does not pay attention to keeping warm, it will cause a lot of heat and energy loss in the body, and face the risk of freezing to death, so what are the life-saving tricks of Tahuang? Growing at an altitude of more than 4,000 meters, most plants have evolved into cushion-like or creeping in order to resist the wind and cold, but Tahuang does the opposite, its secret weapon against the cold is the milky yellow bracts wrapped on the outside of the inflorescence that will be stacked together to form a relatively closed environment.
Tahuang uses bracts to build a 2-meter-high tower, which is still used to heat itself. Isn't it amazing that you can also heat it yourself, and how does it work? The translucent characteristics of bracts make it possible to pass through a large amount of visible light and infrared light, bracts contain a large number of flavonoids, can absorb and reflect more than 90% of ultraviolet radiation, a large amount of visible light and infrared light contains a lot of heat, the temperature inside the airtight bract can be more than 10 ° C higher than the external environment, like not like a pocket-sized "greenhouse", this small "greenhouse" also has a magical effect.
Whenever it is windy and rainy, the small "greenhouse" attracts all kinds of insects to take the initiative to come to the bracts of tower yellow to hide from the rain for heating, these small insects in the rain to warm up, can automatically complete the pollination work of tower yellow, tower yellow not only the aboveground part of the shape is peculiar, deep underground roots developed, up to 2 meters, its role in soil and water conservation far beyond many plants, tower yellow precious lies in the root system and the middle part of some yellow powder, can treat the accumulation of food stagnation, but also the effect of stasis and swelling, In addition, tahuang has a miraculous effect on the treatment of headache amenorrhea.
Tahuang grows at the highest altitude on the mainland and is also the most mysterious territory in China, and its tenacious vitality is shocking, relying only on a small amount of soil between the rocks to survive in the extreme environment of wind, frost, rain, snow, and scorching sun, opening up a new way for the Tibetan people to get rich.
