Complete cultivation process of Pleurotus eryngii

Complete cultivation process of Pleurotus eryngii

It is divided into four major stages: **fungus bag preparation, mycelium cultivation, budding promotion, and harvesting and processing**. The factory-based standardized process includes: material preparation → ingredient mixing → bagging → sterilization → cooling → inoculation → mycelium cultivation → scratching → budding promotion → bud thinning → fruiting management → harvesting → grading and packaging.

1. Fungus bag preparation stage

1. **Ingredient ratio**

Main raw materials: agricultural by-products such as corn cob, mixed sawdust, wheat bran, soybean meal, gypsum, and lime, with no mold or impurities; add water and mix, control the moisture content at 60-65%, adjust the pH to slightly neutral, and ensure the nutritional supply for mycelium ...

2. **Bagging and filling**

The automated equipment loads the mixed culture material into the mushroom bags, ensuring proper tightness. The bag opening is sealed with a loop, leaving a reserved ventilation channel.

3. **High-temperature sterilization**

The process of sterilizing raw materials in a sterilization cabinet under high temperature and high pressure to eliminate internal bacteria and insect eggs and prevent subsequent contamination is a crucial step in production.

4. **Sterile cooling**

After sterilization, transfer the materials to a clean cooling room. Wait until the material temperature drops below 28℃ to avoid killing the bacterial cultures due to high temperatures.

5. **Vaccination**

The sterile purification workshop introduces superior strains of Pleurotus eryngii, seals the bag opening, and strictly prevents the intrusion of miscellaneous bacteria throughout the entire process.

II. Mycelium cultivation (germination)

Place the inoculated fungal packets into the **dark cultivation chamber**.

- Temperature control at 22-25℃, humidity at 60-70%, with regular ventilation.

- Keep the environment completely dark throughout the entire process. As the mycelium consumes the material and grows, it usually takes 30 to 45 days for the mycelium to cover the entire mushroom spawn. Conduct regular inspections and remove any moldy or contaminated mushroom spawn.

After the mycelium is fully grown, do not harvest the mushrooms immediately. Let it sit for 7-10 days to complete physiological maturation and enhance the quality of the mushrooms.

III. Scratching and bud forcing

After the mycelium matures, it is transported to the mushroom cultivation room.

1. **Scraping the mycelium**: Remove the old mycelium layer on the surface of the material to stimulate the germination of the primordium. The temperature should be controlled at 15-18℃.

2. **Bud forcing**: Increase the air humidity to 90-95%, enhance diffused lighting, improve ventilation, and create a moderate temperature difference to encourage the emergence of white mushroom buds.

IV. Mushroom production management and bud thinning

1. When the mushroom buds grow to 2-3 cm, carry out **thinning** to remove weak and malformed mushrooms. Only retain 1-2 healthy buds per bag to concentrate nutrients, ensure robust mushroom bodies, and reduce malformed mushrooms.

2. Environmental parameters during mushroom cultivation:

Temperature: 13-16℃; Humidity: 85-90%; Weak scattered light; Ventilate multiple times daily. **Do not spray water directly onto the mushrooms**, but rather increase humidity on the ground of the space to prevent mushroom rot.

3. After 8-12 days of growth, the Pleurotus eryngii gradually grows larger, with the mushroom body becoming firm and plump.

V. Harvesting, grading and packaging

When the mushroom body grows to 15-18 cm, and the cap has not fully expanded, it can be harvested and supplied to the whole country once it meets the commercial standards ...

1. Pick the whole flower and remove the old roots and impurities at the bottom.

2. Sort and screen according to size and quality, removing deformed and damaged mushrooms.

3. Pre-cooling of packaging, storage for freshness preservation, and external sales.
