Everyone came to a greenhouse, and a sign saying "Edible Fungi" was hung at the door.

Walking into the greenhouse, Grandpa Yuan pointed to the isolation rooms and said: "This is the wood fungus area, and the cellulose and lignin of wood are used as carbon nutrition. Cultivated shiitake mushrooms, tiger skin shiitake mushrooms, pink side ears, yellow and white side ears, pink fold side ears, blood ears, oyster mushrooms, elm yellow mushrooms, tea mushrooms, etc., they are suitable for growing in broad-leaved wood. Species such as leopard mushrooms and shellfish-shaped ears are suitable for growing on coniferous trees; Such as capsule, spoon-shaped ear, leather, purple leather, white fungus, black fungus, hairy fungus, white fungus, sand fungus, enoki mushroom, heap of money mushroom, dense ring fungus, Zhu Ling, steak mushroom, ink ghost umbrella, hairy ghost umbrella, slippery mushroom, lion's mane mushroom, oyster mushroom, silver silk grass mushroom, Ganoderma lucidum, etc., suitable for growing on the wood; Whereas, the ferulum is only suitable for growing on the ferulum plant. You can observe them one by one by the nameplate. ”

"There are so many types of edible mushrooms!" Yeon-yeon was amazed.

"Edible mushrooms were originally cultivated in this way~ Different edible mushrooms grow on different types of wood, so amazing! Grandpa Yuan, can we go in and have a look? Kiki wanted to go in and touch it, as always playing the role of a curious baby.

Grandpa Yuan said with a smile: "When you enter the cultivation room, you have to disinfect it, this is transparent glass, and we can see it clearly outside." ”

Yeon-yeon asked, "Do all edible mushrooms grow on wood?" ”

"Come and see here, this is a grass mushroom, they use the nutrients in the forage to live, such as straw mushrooms, wild mushrooms, bisporus mushrooms, white stalk mushrooms, purple mushrooms, oyster mushrooms, wind tail mushrooms, etc. Here are dung mushrooms, including straw mushrooms, mushrooms, tall ring-stemmed mushrooms, ghost umbrellas, etc. There are also native fungi that use the organic matter in the soil to live as nutrients, such as mushrooms, horsetails, morels, lilac mushrooms, long-skirted bamboo sunflowers, short skirt bamboo sunflowers, etc. Let's take a look around. ”

So, the friends chattered all the way and stopped to discuss in front of the edible mushroom cultivation room they were familiar with.

"This is an oyster mushroom, also known as a side-ear? Good image! We usually call them mushrooms. ”

"Mushrooms are wild, aren't the little girls picking wild mushrooms in "The Little Girl Picking Mushrooms"?"

"Wild mushrooms are highly nutritious, colorful, and beautiful!"

"Wild mushrooms are not as fat as this, and they break and break when you touch them."

"Some mushrooms are highly poisonous, and if you don't get it right, you'll die, so it's best not to eat them indiscriminately if you don't have experience!"

……

"This is a tea tree mushroom, it turns out that it grows like this!"

"This is enoki mushroom, used in soup, delicious!"

"Shiitake mushroom~ finally found!"

"This is lion's mane mushroom~ I like to eat it the most! There are hairy fleshy thorns on the surface of the mushroom umbrella, which looks like a golden monkey's head from a distance, so it is called "lion's mane mushroom", and it is like a hedgehog, so it is called "hedgehog fungus" again. It's like, I really want to touch it! ”

"This is fungus, like black ears, hee~"

"This is white fungus, does it look like a petal?"

"Haha~ like a small cloud!"

……

Ding Xuecheng was most concerned about Ganoderma lucidum, and hurriedly ran to the glass room where Ganoderma lucidum was cultivated, and carefully observed through the glass.

Ding Xuecheng watched for a while, and when he saw Grandpa Yuan coming over, he hurriedly asked: "Grandpa Yuan, this is Ganoderma lucidum, it's not big, like ears, and it's so bright, why doesn't it look like the picture in the book?" ”

"The size and morphology of Ganoderma lucidum vary greatly, the cap of large individuals is 20×10 cm, about 2 cm thick, the general individual is 4×3 cm, 0.5~1 cm thick, there are countless small holes below, the nozzle is white or light brown, there are 4~5 per millimeter, the nozzle is round, the inner wall is a solid layer, and the spores are produced at the top of the basidio. Wild Ganoderma lucidum stipe is lateral, rarely partial, longer than the diameter of the cap, purple-brown to black, lacquer-like luster, hard. ”

"Where are wild reishi mushrooms abundant?"

"Ganoderma lucidum, also known as the spirit in the forest, is the best that grows in the forest, and the medicinal effect is the highest. At present, there are also artificial greenhouses, which mainly grow in wetter places. Ganoderma lucidum is widely distributed in Guizhou, Heilongjiang, Jilin, Shandong, Hunan, Huoshan, Anhui, Jiangxi, Fujian, Guangdong, Guangxi, Hebei and other provinces. Among them, the planting bases of Ganoderma lucidum in Northeast China are concentrated in Huangsongdian Town, Jiaohe City, Jilin Province and Huangnihe Town, Dunhua City, Jilin Province. There are also different mass productions in Europe, the Americas, Africa, and East Asia. ”

"Didn't these lingzhi mushrooms grow on wood?"

"This is artificially cultivated in large quantities, which is convenient for controlling the environmental conditions required for Ganoderma lucidum, and the yield is large. 77% cottonseed husk, 10% bran, 10% corn flour, 1% sugar, phosphate fertilizer and gypsum are used as planting ingredients; or 70% sawdust, 25% bran, 2% soybean flour, 1% phosphate fertilizer, 1.5% gypsum and 0.5% sugar. When preparing, first mix the raw materials such as cottonseed husk, sawdust, bran, gypsum powder, etc., with a water content of 60%~65%, so that there is water overflow but not dripping when grasping it with your hands. After the cultivation material is mixed, it is bagged with a bagging machine and inoculated in a sterile room. Then move the inoculated bacterial bag into the sterilized culture room, discharge it in layers, and turn it up and down once a week to ensure that the temperature of the bacterial bag is balanced, increase the oxygen in the bag, promote the germs, and remove the bacterial bags infected by green mold and miscellaneous bacteria. When the mycelium is covered with the bag, use a blade to cut the ends into a circular mouth the size of a 5 dime coin. The cap gradually turns from white to light yellow, from yellow to reddish-brown, the white on the edge of the cap basically disappears, the edge turns red, the cap begins to leather, and when the reddish-brown mist spores eject from the back, it indicates that the fruiting body of Ganoderma lucidum has matured and needs to be harvested in time. It takes 40~45 days from cutting to harvesting. ”

"Grandpa Yuan, I heard that Ganoderma lucidum is very valuable and expensive?"

"Ganoderma lucidum has a history of more than 2,000 years in China, and has been regarded as a miraculous treasure by generations of pharmacists to nourish and strengthen the body. It is known that there are more than 100 species of fungi in the genus Ganoderma lucidum, the most widely distributed is Ganoderma lucidum, followed by Zizhi, as well as tree tongue, pine fir Ganoderma lucidum and book tree lucidum are all used for medicinal purposes. After a large number of clinical studies, Ganoderma lucidum has different degrees of efficacy on neurasthenia, hyperlipidemia, coronary heart disease, angina, arrhythmia, Keshan disease, altitude discomfort, hepatitis, hemorrhagic fever, dyspepsia, tracheitis, etc. Clinical studies have shown that the use of cassia seeds, black oolong and other formulas for the classic formula tea of traditional Chinese medicine can play a good role in the prevention and treatment of hyperlipidemia and other diseases. Pharmacological studies have proved that Ganoderma lucidum has many biological activities, such as liver protection and detoxification, treatment of diabetes, improvement of cardiovascular system, skin whitening, and anti-tumor effects. Li Shizhen pointed out in the "Compendium of Materia Medica" that "Ganoderma lucidum, non-toxic, the main treatment of knots in the chest, invigorating the heart, replenishing the heart, increasing wisdom, not forgetting, long-term food and light body, prolonging the life of the immortals", which means that Ganoderma lucidum has 'increased wisdom and good color', and Ganoderma lucidum is a kind of anti-wrinkle, anti-inflammatory, clear pigmentation, and protect the skin. Reishi mushroom contains ingredients that inhibit melanin and a variety of trace elements that are beneficial to the skin, which can reduce free radicals in the body, accelerate cell regeneration, increase skin thickness and increase collagen, and achieve the effect of plumping the skin and eliminating fine lines and wrinkles. The polysaccharide components can restore skin elasticity by maintaining and regulating the skin's hydration, making the skin moist and delicate, and have antioxidant and anti-aging effects. Based on the above effects, the Ganoderma lucidum on the market is quite popular, and it is the guest of honor of pharmaceutical and beauty manufacturers, and wild Ganoderma lucidum is particularly rare. ”

"Grandpa Yuan, how to distinguish between wild Ganoderma lucidum and artificially cultivated Ganoderma lucidum?"

"Haha, the little guy has a lot of problems! Well, being diligent and inquisitive is a good quality. I'll give you a brief explanation, and you hear me clearly—"

First of all, look at the color and shape of Ganoderma lucidum. Distinguished by the different growth environment, wild Ganoderma lucidum grows mostly on a certain dead tree trunk in the deep mountain woods, and there are many weeds and rocks next to it, so the wild Ganoderma lucidum grows and varies, and the color is different, and the planting of Ganoderma lucidum comes from the planting base, although the growers also deliberately imitate the growth environment of wild Ganoderma lucidum, but most of the long types are relatively uniform, and the color is roughly the same.

The second is to compare the size. There are many varieties of wild Ganoderma lucidum, the shape is relatively irregular, and each type of Ganoderma lucidum has its own characteristics, however, the Ganoderma lucidum collected in the mountains is generally of different sizes, and it will not be like artificial, and the size of large quantities of Ganoderma lucidum is basically about the same size. The general growth environment of artificially cultivated Ganoderma lucidum is in greenhouses, so that the growth environment of Ganoderma lucidum is often much larger than that of wild Ganoderma lucidum, and the size of Ganoderma lucidum is consistent and the shape is regular.

The third is to look at the insect eye. Wild Ganoderma lucidum grows in the wild, and it will definitely encounter insect infestation attacks, so irregular insect eyes will be left under the fruiting body, which is also inevitable, if there is no insect eye, it can only mean that this Ganoderma lucidum is artificially cultivated. Artificially cultivated Ganoderma lucidum generally uses pesticides to control insect pests, and there are almost no insect eyes.

Fourth, it is to smell the smell and taste. The medicinal value of wild Ganoderma lucidum is becoming more and more obvious, why is it called medicine, which can cure, prevent and resist diseases. The taste of wild Ganoderma lucidum is bitter, and it is very bitter, generally speaking, the more bitter it is, the more significant its medicinal effect will be, as the old saying goes, 'good medicine is bitter, bitter medicine is good'. Wild Ganoderma lucidum has no smell, and the smell of Ganoderma lucidum bought in pharmacies is generally due to the mixing of Chinese herbal medicines.

Fifth, look at the grass stalks. Wild reishi mushrooms often have elements of wild nature. The growth environment of wild Ganoderma lucidum is overgrown with weeds, and it is inevitable that there will be grass stalks and Ganoderma lucidum entangled, and often grass stalks will grow in the body of Ganoderma lucidum and penetrate it.

Sixth, the mud of Ganoderma lucidum's feet. Wild reishi mushrooms are sure to be picked with dirt, and the soil is so strong that it's hard to break. And wild Ganoderma lucidum is certainly not collected in one place, so the soil it carries will certainly not be the soil of one place.

"Grandpa Yuan, is there a wild Ganoderma lucidum that is very large and hundreds of years old?"

"Yes, there have been quite a few records in recent years. What I know is that in 2011, deep in the dense forest of Jiulongshan National Forest Park in Jixian County, Tianjin, a villager picked two extremely rare and estimated to have grown for hundreds of years of huge Ganoderma lucidum. In 2014, Hebei discovered a 150-kilogram wild Coriolus with a diameter of 1.38 meters and 12 layers, and Coriolus versicolor is the top grade in Ganoderma lucidum. In the same year, the media reported that 'a 1.7-meter-long giant Ganoderma lucidum weighing 220 kilograms was found in Dak Lak Province in central Vietnam'. In 2015, there was a giant wild Ganoderma lucidum in Hezhou, Guangxi, with a diameter of 1.07 meters and a weight of 14.89 kilograms. In the same year, a giant Ganoderma lucidum tree weighing 70 kilograms and requiring four people to lift in a forest near the border with Laos in the Xiang Duong district of Nghe An province in northern Vietnam was found, and is believed to have grown for thousands of years. ”

"Such a big wild Ganoderma lucidum, one of them will be haired~"

Grandpa Yuan glanced at Ding Xuecheng strangely and said with a smile: "Hehe, the little guy is still a little money fan!" ”

Ding Xuecheng scratched his head embarrassedly, and said shyly: "I just want to see what kind of place such a big wild Ganoderma lucidum will grow......
