Planting methods and techniques of harmless and High yield of Ganoderma lucidum

According to legend, Ganoderma lucidum, which is almost like immortal grass, has very high medicinal value in practice. it can be used for dizziness, palpitation, shortness of breath, neurasthenia, fatigue, coughing and wheezing, relieving cough and relieving asthma and prolonging life. Therefore, the economic benefit of planting Ganoderma lucidum is also very high, so how can it be planted with high yield? Today we will briefly introduce the planting methods and techniques of Ganoderma lucidum.

(1) preparation of nutrients

(1) miscellaneous sawdust about 75%, wheat bran about 25%, ammonium sulfate about 0.2%, mixture water content 70%; (2) miscellaneous sawdust about 75%, wheat bran about 25%, mixture water content 60%; (3) miscellaneous sawdust about 50%, wheat bran about 50%, urea 0.1%, mixture water content 60%; (4) cottonseed husk 79%, wheat bran about 20%, sucrose 1%, mixture water content 60% 65% (5) 50% of corn shaft residue, 30% of sawdust, 20% of wheat bran, 60% of water content of mixture; (6) 75% of poplar leaves, 25% of rice bran (or wheat bran), 60% of water content of mixture; (7) 45% of rice straw powder, about 30% of sawdust, about 25% of wheat bran (or rice bran), and 60% of water content of mixture.

(2) 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.

(3) vaccination and culture vaccination

Inoculation and culture inoculation 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.

(4) Disease control

In the process of production, attention should be paid to prevent the infection of miscellaneous bacteria, such as Penicillium, Mucor and Rhizopus. Prevention and treatment methods: the inoculation process should be strictly aseptic; the culture materials should be sterilized thoroughly; properly ventilated to reduce humidity; those with mild infection should be scraped off the local miscellaneous bacteria and surrounding bark with a disinfection blade, and then smeared with concentrated lime milk. or fill the hole with skimmed cotton dipped in 75% alcohol; those with serious pollution should be eliminated in time. Ganoderma lucidum is a valuable traditional Chinese medicine. It is forbidden to use pesticides. After the mycelium is extracted, Yifuyuan mushroom ecological treasure can be sprayed to supplement nutrition. The attention ingredient of mushroom ecological treasure is bioactive bacteria, which can promote the growth of Ganoderma lucidum bacteria and inhibit harmful bacteria. Form beneficial bacteria biosphere to avoid drug damage.
