Mushroom Growing Humidifier: Things You May Want to Know

Enoki is a delicious edible mushroom and a healthy food that is rich in protein, amino acids, vitamins and minerals. Bottle cultivation of enoki is the main method of factory-based and automated production.

As a leading manufacturer of edible fungus growing equipment in the industry, Henan Joconn has always focused on providing high-quality equipment and excellent services to global customers. Our factory is located in an industrial park with a beautiful environment, covering a large area and well-planned.

1.Raw Material Preparation
Mix raw materials according to the nutritional needs of the mushroom species (e.g., 78% sawdust, 20% bran, 1% gypsum, 1% lime). Use sawdust from broad-leaved trees (e.g., poplar, birch) and screen out large impurities. Bran must be fresh and free of mold, while corn cobs should be crushed into particles 1/4 to 1/3 the size of a corn kernel for uniform mixing. Use a spiral mixer to blend the materials for 15-20 minutes, ensuring even distribution and consistent nutrition to support mycelium growth.、

2.Bag Formation
Use a bagging machine to evenly fill polypropylene bags with the prepared mixture, adjusting weight and compactness as required (e.g., shiitake mushroom bags typically weigh 1.2-3 kg with moderate compactness). After filling, seal the bags with a binding machine to ensure a firm closure, preventing contamination. Machine binding is more efficient and reliable, making it a critical step in the production process.

3.Sterilization
Sterilization is crucial and requires strict control of temperature, pressure, and time:
Atmospheric Sterilization: Place the mushroom bags in a sterilization chamber, maintaining a temperature of 100°C for 10-12 hours using steam.
High-Pressure Sterilization: Sterilize under high temperature and pressure (121°C, 0.1-0.15 MPa) for 2-3 hours. This method is more effective but involves higher equipment costs. After sterilization, allow the bags to cool to a safe temperature before moving to the inoculation stage.

4.Inoculation
Inoculation must be performed in a sterile environment. Operators wear sterile clothing and use disinfected tools (e.g., inoculation needles, scoops) to evenly introduce the spawn into holes or onto the surface of the mushroom bags. The inoculation amount depends on the species and bag size (e.g., 10-15 g per bag for enoki mushrooms). The inoculation room is equipped with air filtration systems, UV lamps, and ozone generators to maintain sterility. Pass-through windows facilitate the transfer of materials while minimizing external contamination.

5.Cultivation
Place mushroom bags on multi-layer cultivation racks with adequate spacing for ventilation and observation. Adjust the environment based on the mushroom species:
Temperature: 22-26°C for shiitake, 20-25°C for king oyster mushrooms.
Humidity: Maintain at 60-70% using humidifiers or dehumidifiers.
Light: Oyster mushrooms thrive in diffused light, while enoki mushrooms grow better in darkness.
Ventilation: Ensure 1-2 air exchanges per hour to meet the oxygen needs of the mycelium.
Regularly inspect the growth conditions, and adjust ventilation or environmental parameters if excessive growth or abnormalities are detected, ensuring smooth cultivation progress.

Edible Mushroom Mite Control Technology Optimization
About 7 days after sowing edible mushrooms, effective mite control measures should be taken to ensure production quality. The following are detailed methods for mite control:
Observation and Detection
After covering the substrate with a colored film for 5-10 minutes, closely observe the culture material with a magnifying glass. Once small, flat or oval-shaped, white or yellow mites with multiple bristles are found, immediately take the following measures to eliminate them:
1. Fumigation for Mite Control
Soak cotton balls in dichlorvos and place them on the substrate under the bed frame. Cover the bed surface with plastic to allow the fumes from the pesticide to kill the mites.
2. Pesticide Spraying for Mite Control
Use the following pesticide solutions for spraying:

50% oxydemeton-methyl 1000 times solution
Pyrethrin 1500 times solution
Acaricide 500 times solution

Alternatively, spraying with 400 times diluted laundry detergent solution can also effectively control mites in 2-3 applications.
3. Rapeseed Cake Attractant for Mite Control
Place damp cloths on the infested substrate and scatter freshly roasted rapeseed cake powder on top. When the mites gather on the rapeseed cake powder, remove the cloth and place it in boiling water to kill the mites.
4. Vinegar-Sugar Pesticide Attractant
Prepare a vinegar-sugar solution:

1 part acetic acid
1 part water
0.1 part white sugar
1-2 drops of dichlorvos

Soak a piece of cloth or cotton in the solution and place it on the substrate. When the mites gather, remove and boil to kill them. Repeat the operation until all mites are eliminated.
5. Fresh Bone Attractant for Mite Control
Place fresh pig bones evenly on the affected substrate. When mites gather on the bones, place the bones in boiling water to kill the mites. Repeat several times until the substrate is free of mites.
Control Suggestions

Prevention First: Keep the culture material and surrounding environment clean to prevent mite infestation.
Prompt Action: Take immediate measures once mites are detected to prevent widespread infestation.
Safe Operation: When using chemical pesticides, follow the correct dilution ratios to ensure production safety and product quality.

By implementing these control measures, mites in the edible mushroom production process can be effectively managed, improving both yield and quality.

Mushroom production heavily depends on cultivation bags. As the saying goes: "Mushrooms first, bags second, management third." This highlights the importance of bag quality as the foundation of successful mushroom cultivation. However, issues like bag rupture, contamination, uneven substrate adhesion, or poor fruiting often stem from overlooked bag quality and selection, which ultimately impacts mushroom yields.
Today, we will discuss how to assess the quality of cultivation bags and share some practical tips for selection.


Methods to Assess Bag Quality
1. Check the Appearance
Align the bottom seal and the opening of the bag. If the edges are uneven, the bag is likely handcrafted, which makes it less airtight. On the other hand, machine-sealed bags are evenly aligned and generally offer better airtightness and sealing.
2. Inspect the Heat-Sealing Line
If the sealing line is opaque, it indicates manual sealing. Such bags have poor plasticity, are prone to air leakage, and are stiffer, making them more susceptible to breakage. In contrast, machine-sealed lines are transparent, soft, and durable, ensuring over 95% airtightness and reliable sealing.

3. Examine Bag Color and Consistency
High-quality bags have a clear, uniform, and smooth appearance. To check thickness, open the bag and feel it by running your hands around in a circle. If you notice uneven thickness or thin spots, the bag is likely to tear easily.

4. Puncture Test with Fingernail
Inflate a bag and seal it. Try puncturing it with a fingernail. If the bag does not leak, it indicates good quality.
5. Submersion Test
Seal the inflated bag and submerge it in a water basin. If no bubbles appear, the bag is airtight and meets quality standards. Bags with leaks are more prone to contamination during cultivation.

6. Feel the Surface
Run your hands over the surface of the bag to check for smoothness. A smooth surface suggests that the bag contains fewer recycled materials, indicating higher quality.

7. Inspect Against Sunlight
Hold the bag up to sunlight to check for small black dots. These dots are unmelted particles from recycled materials. If such particles are abundant, avoid using the bag.
8. Stretch Test
Cut a strip about 1 cm wide from the bag. Hold both ends of the strip and gently pull to stretch it. The farther it stretches without breaking, the better the bag quality.



Additional Tips
There are many ways to evaluate bag quality, but it’s crucial to select cultivation bags from certified manufacturers. Mushroom cultivation is challenging and requires careful attention to every detail. Choosing high-quality cultivation bags is an essential step that should never be overlooked!
