How to supplement the nutrient solution of Flammulina velutipes?

How to supplement the nutrient solution of Flammulina velutipes? Please guide the Flammulina velutipes planted by most mushroom farmers have begun to harvest the second tide mushroom, ready to produce the third tide mushroom, but because the first two tide mushrooms absorb a lot of water in the growth process, resulting in the lack of water and nutrients in the culture material, seriously affecting the yield and quality of the third tide Flammulina velutipes, so replenishing the nutrient solution to the culture material is an essential work. Here, we would like to remind mushroom farmers that there are five things to pay attention to before and after replenishing the nutrient solution. First, clean up the material surface to prevent the residual mushroom roots from infecting miscellaneous bacteria and affecting mushroom production. Second, let the bacterial bag rest for 3-5 days. Should pay attention to the ventilation in the shed, let the material surface slightly dry, in order to promote the recovery of mycelium in the culture material. Third, the concentration of supplementary nutrient solution should be appropriate. In the production of the second tide mushroom, the fruiting body absorbs a large amount of nitrogen, potassium and other mineral elements from the culture material, resulting in an imbalance of carbon and nitrogen in the culture material, so it is necessary to supplement nitrogen and potassium in time. Mushroom farmers can configure the nutrient solution according to 100 kg of high energy and water per 300 ml mushroom ear. Fourth, it should be carried out in accordance with the principle of less rather than more, and how many mushrooms are picked to replenish the nutrient solution. When replenishing the nutrient solution, do not supplement too much, in case the nutrient solution will squeeze out the oxygen in the culture material, resulting in mycelium hypoxia, or even rotten bags. 2-3 days after replenishing water, check whether all the nutrient solution in the bag is infiltrated into the culture material. If there is still uninfiltrated nutrient solution in the bag, the mushroom farmer should pour it out in time. Fifth, cover the plastic film 2-3 days after replenishing the nutrient solution. The plastic film should not be covered immediately after replenishing the nutrient solution to prevent excessive humidity of the material surface and infection of miscellaneous bacteria. Mushroom farmers should wait until the mushroom surface is slightly dry and then cover the film to keep warm and moisturize, increase the concentration of carbon dioxide around the fruiting body and promote rapid budding. At the same time, reduce the oxygen concentration around the fruiting body, promote the elongation of the bacterial leg, and prevent the bacterial cap from being too large.
