Mushrooms have always been a very popular food on people's tables, there is a great market demand, we can grow mushrooms through the realization of the mushroom to become rich, the key to which is to scientific and rational planting, reduce costs and increase income, improve economic efficiency and promote economic development. Next to give you a detailed introduction to some of the methods of mushroom cultivation.

One, mushroom shed construction

Sheds should be covered with straw curtains or awnings. Take autumn mushroom cultivation as an example, the mushroom shed should be built towards the south, east and west, with no column insulation shed. The back wall is hollow brick, 60 cm thick and 2.2 meters high. Every 3M, 50cm from the ground, a 60cm vent is reserved. The greenhouse is 60 ~ 100 meters long, 8 ~ 12 meters wide, and no more than 13 meters wide.

Two, mixing material selection

Selected fresh hardwood, processed into 16 ~ 20 mm wood chips. The proportion of ingredients is 78% wood chips + 20% bran + 1% gypsum powder + 1% excipient. After the material is prepared, pre-wet the wood chips, evenly sprinkle the bran and gypsum into the wood chips, add water to mix, turn 4-5 times, mix well and keep the moisture content at 58-60%.

Three, bagging and sterilization

1t dry wood chips can be made into 700 ~ 800 sticks. A single shed needs 20 ~ 25t of culture material and 17000 ~ 18000 sticks.

Sterilization method of space bag: the bag is put in layered or non-layered bag. Firing with a pot, the pot temperature reaches 100 ℃ for 4 ~ 6 hours. Continue to heat and maintain at this temperature (airtight for 24 hours), then let it simmer overnight. When the material temperature drops to 70°C, the pot temperature is absorbed and quickly moved to the cooling chamber. When the temperature inside the bag drops to 20°C, inoculation begins.

Four, inoculation

Before inoculation, use tools such as polymyxin to sterilize the environment. Put the inoculation stick, mushroom bag and other tools into the inoculation box and sterilize it for 30 minutes with the sterilizing box. One inoculation stick has 3 ~ 5 inoculation holes, and one inoculation box inoculates 50 ~ 60 inoculation sticks at a time. Multiple inoculation boxes can be recycled for sterilization and inoculation.

V. Greenhouse Cultivation

Bacterial culture time is about 4 months. Requirements sealed, dry, temperature of 20 ℃ ~ 25 ℃. When the mycelium grows to 5 centimeters, check for stray bacteria. When the mycelium grows to 8 cm, remove the outer bag. Ventilate regularly to avoid scorching the bacteria at high temperature. When the mycelium is so full that it occupies more than 2/3 of the bag, start piercing.

Sixth, water injection

After bagging, enter the production management period of shiitake mushroom. After bagging, spray water in time to keep the humidity in the shed above 90%, diffuse light, control the temperature between 10℃ - 20℃, keep 10℃ temperature difference. After picking the first mushroom, water it to the weight of the stick. Before each mushroom, spray water in time to keep the humidity in the shed above 90%.

The above is the introduction of the method of growing mushrooms for you to understand the reference and learning. I hope it will be helpful to everyone.
