How to grow Ganoderma lucidum

Ganoderma lucidum has been the representative of fairy grass for a long time, especially in the New White Lady, after White Snake brought Xu Xian back to life with Ganoderma lucidum, Ganoderma lucidum became more and more ingrained. With the deep excavation of Ganoderma lucidum by science and technology, Ganoderma lucidum will gradually come down from the altar and become a widely planted medicinal material.

How to grow Ganoderma lucidum

I. preparation of nutrients

1. Sawdust about 75%, wheat bran about 25%, ammonium sulfate about 0.2%, water content of mixture 70%.

2. The sawdust is about 75%, wheat bran is about 25%, and the water content of the mixture is 60%.

3. Sawdust about 50%, wheat bran about 50%, urea 0.1%, water content 60%.

4. Cottonseed husk 79%, wheat bran about 20%, sucrose 1%, water content 60% Mel 65%

5. Corn shaft residue 50%, miscellaneous sawdust about 30%, wheat bran about 20%, water content of mixture 60% Mui 65%.

6. Poplar leaves 75%, rice bran (or wheat bran) 25%, water content 60%.

7. 45% of rice straw powder, 30% of miscellaneous wood chips, 25% of wheat bran (or rice bran), and 60% of water content of mixture.

II. Charging and sterilization

Mix the culture material, simmer for half an hour and then load. Conventional plastic bags can hold 0.25ml 0.3 kg of dry material. When bagging, the material should be compacted by hand and the material surface should be flat, then use a tapered wooden stick to pierce a 2.5 cm diameter vent from the middle of the material surface, plug the cotton plug at the mouth of the bag and wrap a layer of Kraft paper. If bottled, you can use a jar or mushroom bottle with a volume of 500ml and a caliber of 3.3mur4.6 cm. The filling method is basically the same as the bag method. After loading, arrange the material bag (or bottle) in the pot in layers and sterilize 1mi for 2 hours under the pressure of 1.5kg / sq cm, or sterilize 8mi for 10 hours under normal pressure. It is required to be loaded, sterilized and vaccinated on the same day.

III. Inoculation and cultivation

Culture and vaccination is best carried out in the inoculation box, if there is no inoculation box, above the alcohol lamp flame or above the boiling water vapor. The inoculation room and vaccination tools should also be strictly disinfected. The staff should put on masks and wash their hands three times with soap. Take a jujube-sized strain from the bottle with inoculation rakes or tweezers and quickly put it into the cultivation bottle (bag). Then the bottle mouth (or bag mouth) is stuffed with cotton stopper and wrapped with Kraft paper, and transferred to the sterilized culture room for culture and sterilization. Keep the room temperature 24 ℃-28 ℃, and the mycelium will be full in the bottle (bag) about 25 days after inoculation. In the germicidal stage, the management should be strengthened to prevent miscellaneous bacteria pollution, and those with miscellaneous bacteria pollution should be eliminated in time.

When the bottle (bag) is full of hyphae, the white buds with large fingers gradually appear on the surface of the culture material, that is, the fruiting body primordium. When its growth is close to the cotton stopper, the cotton plug can be removed, the room temperature is controlled at 26 ℃-28 ℃, the relative humidity is increased to 80% RMI 90%, the scattered light is given, and the air is ventilated every day. After about 20 days, the bottle (bag) mouth of the stalk can grow, and the end of the stalk can differentiate into the lid. When the light white or light yellow on the edge of the cap disappears, the edge of the cap stops growing and becomes hard, and it can be harvested when the color changes from bright to dark pink brown.

Key points of High-yield cultivation of Ganoderma lucidum

1. Choose the suitable cultivation period: in Taizhou City, Jiangsu Province, the most suitable cultivation period for Ganoderma lucidum is from April 10 to May 10, and after May 20, the bags are opened to produce Ganoderma lucidum. It is the rainy season from June to July every year, so it is necessary to ensure that all the bags of Ganoderma lucidum are opened before June 10, so that the growth of Ganoderma lucidum fruit body can be in a high temperature and humidity environment, so as to achieve high and stable yield.

2. The culture material should be fresh and dry: the culture material for cultivating Ganoderma lucidum should be especially fresh and dry. The fresh culture material is rich in nutrition and less in miscellaneous bacteria, which is beneficial to the germination of hyphae and inhibit the growth of miscellaneous bacteria.

3. Ventilation during the bacterial period: Ganoderma lucidum is a kind of aerobic fungus. In the process of cultivating Ganoderma lucidum, we must pay attention to ventilation. When making Ganoderma lucidum sticks, it is best to seal them with plastic and cotton plugs. For the bacterial bag with plastic rope, after the cover of the mycelium, micropores must be placed at both ends of the bag to ventilate.

4. Reasonable water spraying during the sesame period: during the growth of Ganoderma lucidum fruiting body, the air humidity of Ganoderma lucidum room is 85% Mel 95. Under the condition of suitable environmental temperature, too low humidity will make the fruiting body of Ganoderma lucidum thin, even ossified. The water management in the initial stage of fruiting body formation is mainly wall, bed frame, floor and space spraying. When the diameter of Ganoderma lucidum cap is larger than 3cm, it is necessary to increase the number of water spraying with the increase of ventilation rate, and spray it directly to Ganoderma lucidum 4 times a day.

5. It is appropriate to adopt the method of imitating wild cultivation: under the same cultivation conditions, wall-like wild cultivation can increase the yield by 20% and 30% compared with bag cultivation. Because when imitating wild cultivation, the soil contains the nutrients needed for the growth of Ganoderma lucidum, and the soil has good water holding capacity, which can provide suitable, sustainable and stable water conditions for the growth of Ganoderma lucidum. And the hyphae can exert their overall advantages by extending and growing in the soil.

The origin of Ganoderma lucidum

Ganoderma lucidum is native to eastern Asia, and Jiangxi is the most widely distributed in China. It is cultivated in most parts of the country, and Lushan Mountain in the south is the most famous.

Ganoderma lucidum is produced in Europe, America, Africa and eastern Asia. It is widely distributed in China, but it is mostly in the south of the Yangtze River, and it is distributed in the high-temperature and rainy area south of the Yangtze River. The specific provinces are: Anhui, Jiangxi, Fujian, Guangdong and Guangxi.

The species of Ganoderma lucidum in the world are mainly distributed in the tropics and subtropics of Asia, Australia, Africa and America, and a few in temperate zones. Located in the temperate zone of the Northern Hemisphere, there are only four species of Ganoderma lucidum in Europe and about five species in North America. Ganoderma lucidum is widely distributed in China, which spans from tropical to cold temperate zones.

Where does Ganoderma lucidum grow?

Ganoderma lucidum is a famous Chinese and foreign medicinal material, which grows in the forest with the best quality and the highest efficacy, mainly grows in humid places, grows on the base of the rotten wood stem of many kinds of broad-leaved trees and on the ground around it, and the fungal stalk is planted on the underground decaying roots and decaying wood. at present, it is also planted in artificial greenhouse. At present, it is known that there are more than 100 species of Ganoderma lucidum, of which Ganoderma lucidum is the most widely distributed, followed by Ganoderma lucidum, Ganoderma lucidum, Ganoderma lucidum and Ganoderma lucidum.

Although wild Ganoderma lucidum absorbs the essence of nature and grows in the most suitable area, with the development of science and technology, good progress has been made in mining Ganoderma lucidum spores and creating a suitable living environment for Ganoderma lucidum. It provides the possibility for the wide application of Ganoderma lucidum in the future.
