How to grow Ganoderma lucidum cultivation techniques

With the increasing difficulty of harvesting wild Ganoderma lucidum and the decreasing willingness of rural population to harvest Ganoderma lucidum, planting Ganoderma lucidum has become the main supplier of Ganoderma lucidum production. According to the current market demand for Ganoderma lucidum spore powder, the cultivation technology of Ganoderma lucidum has become an urgent knowledge for Ganoderma lucidum growers and potential growers.

How to grow Ganoderma lucidum

1. Choose suitable cultivation period: In Taizhou City, Jiangsu Province, the most suitable cultivation period of Ganoderma lucidum is from April 10 to May 10, and after May 20, Ganoderma lucidum will be opened in succession. June-July is the rainy season every year, so it is necessary to ensure that all bags are opened before June 10, so that the growth of Ganoderma lucidum fruit body can be in a high temperature and high humidity environment, so as to obtain 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. Fresh culture medium is rich in nutrition, less miscellaneous bacteria content, conducive to the germination of hyphae, inhibit the growth of miscellaneous bacteria.

3. Ventilation and ventilation during the growth period: Ganoderma lucidum is a kind of aerobic fungus. In the cultivation process of Ganoderma lucidum, ventilation must be paid attention to. When making Ganoderma lucidum sticks, it is best to seal them with plastic and cotton plugs. For bacteria bags tied with plastic rope, after mycelium cover, must be in the bacteria bag at both ends of the hole ventilation.

4. Reasonable water spraying during the period of Ganoderma lucidum: During the growth of Ganoderma lucidum fruiting body, the air humidity of Ganoderma lucidum room is required to be 85%--95%. Under suitable ambient temperature conditions, too low humidity will make Ganoderma lucidum fruiting body thin, or even rigid without hair. Water management at the initial stage of fruiting body formation was mainly water spraying on walls, bedstead, ground and space. When the diameter of Ganoderma lucidum cap is greater than 3cm, with the increase of ventilation, increase the number of water sprays, 3- 4 times a day, directly spray Ganoderma lucidum.

5. Imitating wild culture method should be adopted: under the same cultivation conditions, the yield of wall imitating wild culture can be increased by 20%--30%. Because of the imitation of 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 and stable water conditions for the growth of Ganoderma lucidum. Moreover, hypha can exert its overall superiority by extending and growing in soil.

The main source of Ganoderma lucidum

Ganoderma lucidum is native to eastern Asia, China's most widely distributed in Jiangxi.

Origin: Most areas of the country have cultivation, south Lushan most famous.

Ganoderma lucidum is produced in Europe, America, Africa and East Asia. Widely distributed in China, but mostly south of the Yangtze River, distributed in the high temperature and rainy zone south of the Yangtze River, specific provinces: Anhui, Jiangxi, Fujian, Guangdong, Guangxi.

The world's Ganoderma species are mainly distributed in tropical and subtropical Asia, Australia, Africa and America, and a few are distributed in temperate zones. Europe, which is located in the temperate zone of the Northern Hemisphere, has only 4 species of Ganoderma, while North America has about 5 species. China's cross-tropical to cold temperate zone, Ganoderma species and wide distribution.

Control of diseases and insect pests of Ganoderma lucidum

1. Trichoderma chloromycetes (Penicillium) and Alternaria

On the culture medium, both the stipe growth point and the fruiting layer under the cap of Ganoderma lucidum were vulnerable to damage. Penicillium initial hyphae for white, loose flocculent, sporulation, light green or blue-green. Trichoderma initial hyphae for gray or white dense cotton wool, soon produced yellow rice dumplings, black or dark green conidia. Chloromycetes have strong reproductive ability. After the germination stage of Ganoderma lucidum is infected, the hypha growth is inhibited and the fruit body cannot be produced when it is serious. When the fruit body is infected, it will rot seriously. Alternaria sp. is rampant in summer with high temperature and humidity. It spreads rapidly mainly at the mouth of culture bag and the root and edge of fruiting body, producing a large number of orange powdery spores. For the prevention and control of miscellaneous bacteria, can choose Clomidine injection, fruiting body can be used Clomidine plus lime scrub or cover, serious can be removed, burned or buried.

2. Fungi flies

Fungi flies lay eggs on the surface of the culture medium, hatch into maggots after a few days, maggots penetrate into the culture medium to destroy mycelium, damage fruit bodies and feed on tissues in the later stage. Before the culture bag enters the shed, 0.2% dimethoate or 0.2% enemy should be sprayed inside and outside to kill the insects completely.

Ganoderma lucidum harvesting and processing

Cut with a knife from the middle of the handle, do not break the cut, spread dry, or low temperature drying. If spore powder is collected, clean plastic cloth or smooth and clean paper can be placed on the culture shelf, collected with a board brush, and the spore powder is dried and stored in a plastic bag for medicinal use.

Although Ganoderma lucidum is widely distributed in the world, it is not so simple to create an environment suitable for Ganoderma lucidum growth. Although Ganoderma lucidum belongs to a kind of fungus, it has great similarities with general fungi in planting, but due to the particularity of Ganoderma lucidum, planting Ganoderma lucidum still needs special attention.
