What are the inoculation and fruiting management of straw mushroom cultivation?

The growth of mycelium of straw mushrooms, as well as the yield and quality of fruiting bodies, are directly affected by the growth environment. We must pay great attention to good management, especially in field cultivation. The climate and environment are changing at any time, and many factors are beyond human control. Therefore, we should pay close attention to the changes in environmental factors in the cultivation warehouse and do a good job of management every day to strive for a better harvest.

1. Inoculation

The sowing method for straw mushroom cultivation adopts the broadcasting method, and the fungus is sown on the surface of the culture medium. The inoculation amount is preferably 200~300 grams/square meter.

2. Mycelium growth stage management

(1) Mycelium stage management focus: The mycelium growth stage includes from inoculation to the mycelium growing full of the material layer. The key point of management work is to promote mycelium growth and prevent the occurrence of diseases and pests.

(2) Film insulation: After the inoculation, the culture medium is covered with plastic film, and the surface temperature of the material is maintained at 35~36℃. When waste cotton and edible mushroom residue are used as the main cultivation materials, the covering time is only 24 hours; when straw is used as the main cultivation material, the covering time should be appropriately extended, generally not more than 48 hours. During the film covering and heat preservation period, the film should be opened at least twice a day for ventilation.

(3) Maintain humidity: During the mycelium growth stage, the relative humidity of the air should be maintained at 80%~85%. In the 4~6 days after inoculation, the space can be humidified appropriately. Do not spray water directly on the surface of the material to avoid inhibiting the growth of mycelium.

(4) Spraying heavy water: On the 5th to 7th day after inoculation, when the mycelium has grown to the bottom of the material surface, spray 0.5~1 kg/m2 of heavy water until water droplets seep out from the bottom of the material, and maintain the room temperature at 28~30℃ for 5~6 hours.

(5) Reheating to promote mushroom growth: After spraying heavy water, wait until the surface of the material is dry, close the doors and windows, and let the room temperature rise to around 33℃ and maintain it for 12 hours to allow the mycelium to resume growth. However, the temperature recovery time should not exceed 12 hours.

(6) Spraying mushroom water: Spray mushroom water again on the second day after spraying heavy water. Because some small mushroom buds have been formed, the amount of water should be small and the droplets should be fine. Generally, 100 to 200 kg of water should be sprayed for 100 square meters of cultivation area.

(7) Light stimulation: After spraying heavy water, light should be strengthened to promote the formation of mushroom buds. Increasing light can improve the yield and quality of straw mushrooms.
