Guidance on resuming production of Edible Fungi after disaster

First, timely snow removal and drainage. Pay close attention to the changes of the weather, timely remove the ice and snow accumulated on and around the mushroom shed to prevent collapse; open a good drainage ditch around the mushroom shed and clear the ditch for drainage.

Second, repair the damaged and collapsed mushroom shed. Timely remedial measures should be taken for the mushroom shed damaged and collapsed by the disaster. Repair can be repaired, and those that cannot be repaired should be cleaned up in time to prepare for spring ploughing production.

Third, clean up dead mushrooms. Timely remove the dead mushrooms on the mushroom bed that are withered and yellow by freezing injury, so as to avoid diseases and insect pests caused by the decay of dead mushrooms after the temperature rises.

Fourth, loose material to make up the soil. When the temperature rises to 10 ℃, it is necessary to loosen the material and replenish the soil in time, which will not only help to remove the waste gas from the culture material, but also promote the fracture of the old mycelium, promote the growth of new hyphae, form a strong mycelium, and lay a foundation for mushroom production in spring.

The loose material can be divided into big pine, medium pine and small pine, which should be determined according to the actual situation of bacteria bed culture material. For the mycelium growth is exuberant, the soil layer mycelium plate fungus bed, should use big loose; can scrape the fine soil to one side, insert the bamboo stick obliquely into the soil layer bottom pry the coarse soil, pick out the dry dead old hyphae, sprinkle 0.2 kilograms of lime powder per square meter, and then re-smooth the fine soil. For the hyphae of the soil layer, medium loose or small loose is used; when loosening the material, it is not necessary to pry out the fine soil, pry the thick and fine soil together, and then fill the depression of the material surface with new soil.

Fifth, fertilize and replenish water. After the continuous emergence of mushrooms in last autumn, the nutrition loss was serious and the PH value decreased a lot. After the beginning of spring, it is necessary to fertilize and replenish water in time in order to achieve high yield.

All localities can adopt measures in accordance with local conditions and use local materials, and choose one of the following methods, and the effect of topdressing and replenishing water is very ideal.

1, fermentation material soaking juice: cut up the sun-dried fermentation material, add 10 times the dry weight of boiled water, soak for one night to take its filtrate, and then add twice as much water, spray to the bed.

2. Urea water: take 50 grams of urea and 10 grams of glucose to mix 0.1-0.2% urea water as topdressing, which can significantly increase the yield in the middle and later stage, and the mushroom quality is whiter and tender.

3. Polyvalent nutrients of edible fungi: nutrients can rejuvenate mycelium, accelerate mycelium growth, promote fruiting body formation and accelerate hypertrophy. When in use, add 40-50 kg of water per 100 grams and spray 0.3-0.4 kg per square meter.

4. Human and animal urine diluent: boil fresh urine water until the foam disappears, add 10 times water, divide into 3-4 times before mushroom production, spray 0.5-1 kg per square meter on mushroom surface, and then spray with water again after spraying. In addition, 2% lime water should be sprayed 1-2 times before mushroom topdressing, and the PH value of the soil layer should be adjusted between 7.8 and 8.5.

Sixth, heat preservation and ventilation. With the rise of the temperature, pay close attention to the air condition in the shed and ventilate at the right time. The air in the shed should not only be kept fresh and mildew-free, but also keep the temperature from being too low so that people don't feel bored.
