Guidance on Post-Disaster Production Recovery for Edible Fungi, Please Check

    1. Remove snow and drain water in time. Pay close attention to weather changes, promptly clear accumulated snow and ice on the top and around the mushroom sheds to prevent collapse; open drainage ditches around the mushroom sheds and clear the ditches for drainage.

    2. Repair damaged and collapsed mushroom sheds. Timely remedial measures should be taken for mushroom sheds damaged or collapsed by the disaster. Repair what can be repaired; for those that cannot be repaired, clean them up promptly to prepare for spring plowing production.

    3. Remove dead mushrooms. Promptly pick off the dead mushrooms that have turned yellow and withered on the beds due to freezing damage, so as to prevent the dead mushrooms from rotting after temperatures rise and causing diseases and pests.
    4. Loosen the substrate and add soil. When the temperature rises to 10°C, promptly loosen the substrate and add soil. This not only helps expel waste gases from the compost, but also helps break the old mycelium, promote the growth of new mycelium, and form strong mycelial vigor, laying the foundation for spring mushroom production.

    Substrate loosening is divided into three types: deep loosening, medium loosening and light loosening, and should be determined according to the actual conditions of the compost in the mushroom bed. For mushroom beds with vigorous mycelial growth and where the mycelium in the soil layer has formed a hardened mat, deep loosening should be used; scrape the fine soil to one side, insert a bamboo stick diagonally into the bottom of the soil layer to pry up the coarse soil, remove the dry and dead old mycelium, spread 0.2 kg of lime powder per square meter, and then spread the fine soil back evenly. For those with weak mycelial growth in the soil layer, use medium or light loosening; when loosening the substrate, there is no need to pry out the fine soil - pry up both coarse and fine soil together, then use new soil to fill the depressions on the surface of the substrate.

    5. Apply supplementary fertilizer and replenish water. After continuous fruiting since last autumn, the compost has suffered serious nutrient loss, and the pH value has also decreased considerably. After the beginning of spring, supplementary fertilizer and water must be applied in time so that spring mushrooms can achieve high yields.          

    All localities may adapt to local conditions and use local materials, choosing any one of the following methods; the effects of supplementary fertilization and water replenishment are all quite ideal.

    1. Fermented material soaking liquid: cut dried fermented material into pieces, add boiling water at 10 times the dry weight, soak overnight, take the filtrate, add 1 times the amount of clean water, and spray it on the bed surface.

    2. Urea water: take 50 grams of urea and 10 grams of glucose, add water to make a 0.1-0.2% urea solution as supplementary fertilizer. This can significantly increase the yield in the middle and late stages, and the mushrooms are whiter and more tender.

    3. Edible fungus multivalent nutrient: the nutrient can rejuvenate the mycelium and accelerate mycelial growth, and can promote fruiting body formation and accelerate enlargement. When using, add 40-50 kg of clean water per 100 grams, and spray 0.3-0.4 kg per square meter.

    4. Diluted human and livestock urine: take fresh urine, boil it until the foam disappears, add 10 times the amount of clean water, and before fruiting, apply it in 3-4 applications at 0.5-1 kg per square meter sprayed on the mushroom surface, then spray once more with clean water after each application. In addition, when applying supplementary fertilizer before fruiting, 2% lime water should also be sprayed 1-2 times to adjust the pH value of the soil layer to between 7.8-8.5.

    6. Keep warm and ventilate. As the temperature rises, pay close attention to the air conditions inside the shed and ventilate in a timely manner. The air inside the shed should remain fresh and free of musty odor, while also keeping the temperature from becoming too low; it is sufficient if people do not feel stifled.
