The pine hair on the tip of the tongue is endangered? "Killing chickens to collect eggs" results in decreasing yields.

How come the pine hair on the tip of the tongue is endangered?
, known as the "King of All Things", was listed on the World's Red List of Endangered Species for the first time by the World Conservation Union.
has always been an extremely precious natural bacteria, but also China's secondary endangered species. So why is pine wool so rare, and why is it endangered? Science and Technology Daily reporter interviewed well-known domestic wild bacteria research experts.
"King of All Bacteria" is not a false name
pine hair is called matsuguyu mushrooms, alias pine, heptic, Taiwan bacteria, is a special species in Asia, Europe and the United States have variants, but the yield is small, the quality is also poor. China's pine hair is mainly distributed in Yunnan, Sichuan and Tibet, the northeast region and most of the country's provinces and regions also have distribution, the quality of the production of Yuchuan Tibetan as a good, so the southwest region is the main production area of pine hair, production accounted for more than 90% of the country, of which Yunnan pine hair annual output accounted for more than 60% of the country.
, known as the "King of All Things", is not a false name.
According to the study, pine hair contains 18 amino acids, 14 essential trace elements of the human body, 49 active nutrients, 5 unsaturated fatty acids, 8 vitamins, 2 glycogens, rich dietary fiber and a variety of bioactive enzymes, and contains 3 precious bioactive substances, namely pine polysaccharides, pine peptides and the world's only anti-cancer substance - pineal. In addition, its crispy sweetness of the special taste and medicinal value, but also make it in recent years doubled in value.
the country's largest wild bacteria trading market - Yunnan wood water flower wild bacteria trading center, since April this year, fresh hair prices at the highest price of 26,000 yuan per kg. As exports affected by the outbreak were reduced to about two tons per day, coupled with abundant rain, production slightly better, prices have fallen back. Take the July 31 price as an example, according to different grades, the price per kg pine hair between 270 yuan to 800 yuan.
the birth of each pine is a miracle of nature
people say that pine hair, in fact, is a sub-entity of pine fungus.
" pine is also precious because it is very demanding on the growing environment, can only survive in the original forest without any pollution, spores and pine roots must form a symbonic relationship, and the age of symbonic tree species must be more than 50 years to form mycelium and bacteria ponds. It also relies on broad-leaved forests such as cypress and eucalyptus trees to provide nutritional support in order to form healthy sub-entities. Sun Dafeng, director of Kunming Edible Bacteria Research Institute of the All-China Federation of Supply and Marketing Cooperation, told Science and Technology Daily that before the pine hair is unearthed, there must be enough rain to moisturize it, and there must be plenty of sunlight after the excavation. And temperature, insect injury, artificial improper collection and other factors, will have a direct impact on pine growth. It can be said that the birth of each pine is a miracle of nature. "At present, there is no successful precedent for the cultivation of pine wool in the world. Due to the change of environment and large-scale predatory collection in recent years, the production of pine hair is decreasing. Sun Dafeng said.
"Killing chickens to take eggs" type collection is the main reason for the decline in yield
reporters in the interview learned that when a loose open flower aging, will spread tens of billions of spores, these spores fluttering with the wind, only those falling under the pine root system can survive, and with the rain dew sink into the shallow soil, absorb nutrients near the root system, grow mycelium. Mycelium gradually increases and forms roots, and over another 5 to 6 years, a sub-entity grows under the right conditions. And in recent years, large-scale predatory collection, partially blocked the process, bactericidal people often "first come, first expected", less than 5 cm of "child hair" and can produce spores of the old hair is also relentless, "killing chicken eggs" type of collection is the main reason for the decline in pine hair production.
" should be graded harvesting and sales, the protection of bacteria ponds, prohibited from picking sub-standard children's hair and open umbrella mature bacteria, only the harvest of up to 5 cm, meet the conditions of the commodity pine hair. Zhao Qi, a senior engineer at the Kunming Plant Research Institute of the Chinese Academy of Sciences, called for proper and scientific retention in picking to promote the growth and development of mycelium. In addition, it is available to promote the shanyu and contract business model.
Sun Dafeng also pointed out that rational development and utilization is a long-term and sustainable enjoyment of this rare resource premise, and the request for insanity can only be counterproductive. The endangered phenomenon of pine hair is not an exception, such as winter worm summer grass also exists the same over-collection and so on, in addition to the government departments issued corresponding policies and regulations, regulate the industrial process, correct guidance and popular science publicity is also essential. He hoped that all regions as soon as possible to take effective measures to curb the sharp decline in the resources of famous wild bacteria such as pine hair, and through research and promotion of conservation and expansion of technology, play a stable and increased production effect, leaving pine hair to future generations.
