During the production process of mushroom, generally, after harvesting for 3 flushes, nutrient will reduce, acidity will rise, vitality of spawns will drop, yield and quality will reduce. In order to realize good quality and high yield of mushroom, people have to supplement fertilizer. Specialized methods are as follows:
1. Take overrotten swine urine, bovine urine and boil for 20 minutes, add 10 to 20 times of clean water to spray after filtration, then spray clean water for one time.
2. Take overrotten and sundried forage, add 100 times of clean water and boil into juice, after cooling, spray to get robust mushrooms.
3. After finding that the yield of mushroom is going down sharply, people could clean fungi bed, remove old roots and dead mushrooms, smash fresh dried pig manure and cow dung, soak in clean lime water for 15 days, then add silt, which accounts for one third of manure’s total weight, mix well with a few plant ash, scatter on fungi bed and manage in normal ways.
4. Put 2.5kg of plant ash into 50kg of water, take filter liquor and spray to get robust mushrooms and prevent redness of mushrooms.
5. Put 0.5kg of glucose or sugar into 50kg of water, spray after dissolving to get fleshy and thick footed mushroom.
6. Put 250g of salt into 50kg of water, spray in peak season of fruiting to get white and robust mushrooms.
7. Put 0.5kg of lime into 50kg of water, after mixing, take clean liquor and spray, then spray with clean water for one time. This method can adjust PH Value of compost and soil, promote the normal growth of mushroom and should be repeated in every 6 to 7 days.
