How to grow Oyster Mushroom to get high yield?

Oyster mushroom is a popular edible fungus belonging to the phylum Basidiomycetes. It is rich in nutrients and is loved by consumers. Many farmers choose to grow oyster mushrooms to increase their income during the slack season, because oyster mushroom cultivation takes up little land, has low costs, and mainly uses agricultural by-products such as corn cobs, cottonseed hulls , etc. as raw materials, which are easily available in rural areas. Let’s learn together how to grow oyster mushrooms to achieve high yields.

1. Select virus-free strains

Long-term use of non-detoxified varieties of oyster mushrooms can easily lead to infection by diseases, affecting yield and quality. Choose virus-free varieties, such as Kejia No. 1, Defeng No. 5, 8129 Oyster Mushroom, Wanyou No. 5, Wanyou No. 6, 8105, etc., and choose suitable varieties according to local market demand.

2. Selection of culture medium

Common substrates include corn cobs and cottonseed hulls. For every 1,000 kg of corn cobs (after crushing), add 60 kg of high-quality wheat bran , 2 kg of nitrogen, phosphorus and potassium compound fertilizer , 10 kg of high-quality diammonium phosphate, 40 kg of quicklime and 2 kg of carbendazim, and add clean water as needed. When fermenting raw materials, 3000 times diluted insecticide can be added, but no insecticide is needed when cultivating cooked materials.

3. Fermentation culture medium

Mix corn cobs, wheat bran and quicklime powder evenly, add water and stir until there are water drops between your fingers but no water drips when you hold the culture medium in your hand. The culture medium is piled into a circle or rectangle for fermentation, with a pile height of 1.5 meters and a width of 1.7 meters. The length is adjusted according to the amount of material. To prevent overheating in the middle, drill a hole with a diameter of 5 cm from the top of the pile downwards. Drill more holes to facilitate heat dissipation and ventilation. The pile needs to be turned over three times during the fermentation process, on the third, fourth and fifth days respectively, to add pesticides, diammonium phosphate, compound fertilizer and fungicide . Check the moisture content before bagging. It is best if there is a small amount of water between your fingers when holding the culture medium, but no dripping.

4. Mushroom shed disinfection

The place where mushrooms are grown needs to be strictly disinfected to avoid contamination by foreign bacteria. Potassium permanganate can be used to react with formaldehyde to produce fumigation gas for disinfection, or caustic soda can be used for spraying disinfection.

5. Placement of bacteria in bags

Use the 45×25 cm polyethylene mushroom bags sold on the market, and put the spawn into the bags in four layers, two layers at the ends and two layers in the middle, that is, three layers of material and four layers of spawn. Break the fungus into small pieces and stick them close to the edge of the plastic bag. Make small holes in the fungus to facilitate germination and fruiting. Place the mushroom bags in a mushroom shed without direct sunlight.

6. Bacteria management

Fungus management is a key link in the production of Pleurotus ostreatus. The temperature is low in winter, so although a relatively high temperature needs to be maintained during the fermentation process, it still needs to be cooled down to avoid exceeding 30 degrees. When the temperature reaches about 29 degrees, cooling measures need to be taken, such as turning over the stack, spraying water, ventilation, etc., to avoid burning the fungi. The pile needs to be turned over five times during the fermentation process. The temperature is higher in autumn, so it is only suitable to place the plants in a single layer for spawning, and pay attention to insect prevention. Extend the mycelium ripening time for at least two weeks. When the mycelium fills the bag and a small amount of buds appear, you can enter the mushroom fruiting stage to increase the yield of the first wave of mushrooms.

7. Disinfection and preparation of pesticides during the fruiting period

Prepare quicklime and highly effective cypermethrin for disinfection and insecticide. Before fruiting, water should be permeated and 2 to 3 holes with a diameter of 10 mm should be opened at both ends of the bag. During the growth period of the fruiting body, spray water frequently, but not too much, and spray edible fungus nutrient solution several times to promote the growth of the fruiting body.

The above are the key technical points for growing oyster mushrooms. I hope it will be helpful to friends who want to grow oyster mushrooms. If you have other questions, you can also leave a message.
