How to cultivate bag-grown shiitake mushrooms after fruiting

After the mushroom sticks (or bag materials) are full of hyphae, they should be removed from the mushroom room mycelium culture room and moved to the mushroom room or greenhouse to wait for the mushroom sticks (or bag materials) to come out.
In this process, how to manage the bag materials to ensure normal fruiting and high-quality and high-yield after fruiting? To sum it up as a whole: it is to manage the temperature, humidity, ventilation and nutrition of the mushroom house (or fruiting greenhouse).
The following is divided into:
The first is to reasonably adjust the temperature management in the mushroom house or greenhouse according to the season and the temperature outside the shed (house). For example, in places lower than 800m above sea level and 1200~1400m in high mountains, there is a big difference in temperature changes between seasons. This requires mushroom farmers to operate as appropriate according to the actual situation. However, the core content is that the temperature in the mushroom house or greenhouse must be maintained at 25°C to 28°C. If the temperature is too high, the bag material will produce mushrooms quickly, but the fruit body quality is poor and the yield is not high. If the temperature is too low, shiitake mushrooms will produce slowly, and they are prone to the risk of "bad vegetables".
The second is to adjust the relative humidity of the air in the mushroom house or greenhouse. After the bacteria sticks on the rack (or cultivation bed) of the bag material are moved to the fruiting room or the greenhouse, the indoor (or in the shed) air humidity should be controlled at about 90-95%. The air humidity in the mushroom house (in the greenhouse) is controlled at about 85%.
When the air humidity is relatively low, the number of sprays should be appropriately increased. However, when "yellow water" appears on the surface of the bag material on the bed, the ventilation in the fruiting room or greenhouse should be strengthened, and the temperature should be lowered to below 20℃, and the temperature difference between day and night can stimulate the fruiting of the bag material.
The third is to strengthen the daily management of ventilation, so that there is enough fresh air for the mushrooms to come out.
If the concentration of carbon dioxide in the fruiting room is too high, it is not conducive to the development of the mushroom cover. A well-closed mushrooming room should be ventilated at least 2 to 3 times a day for 20 to 30 minutes, and no more than 45 minutes. Good ventilation can ensure the growth and development of shiitake mushroom fruit bodies.
Finally, after the mushrooms have grown out, combined with humidity control (water spraying), the mushrooms can be sprayed with various nutrient fertilizers in an appropriate amount.
In order to prevent the appearance of deformed mushrooms due to the lack of nutrients in the bag material, after the mushrooms emerge, a certain amount of foliar fertilizer can be sprayed on the young mushrooms in combination with water spraying to control the humidity to ensure the growth and development of the young mushrooms for various nutrient elements. .
For example, fresh rice water is a kind of nutrient-rich "foliar fertilizer", which can be sprayed on young mushrooms at the right time. Of course, this kind of mushroom grower, which is only suitable for small-scale lentinus edodes cultivation at home, cannot meet the production needs for mass-produced mushroom growers. Therefore, special foliar fertilizer for shiitake mushrooms on the agricultural material market should be selected for treatment. However, it should be noted that due to different formulations and different doses of different products, please refer to the specific concentration marked on the product packaging to use correctly to ensure the high quality and high yield of shiitake mushrooms.
