Spraying rare Earth solution to promote the growth of Flammulina velutipes

In the cultivation of Flammulina velutipes, spraying rare earth solution on the mushroom bed (culture bag) can promote the mycelium growth and improve the yield and quality of Flammulina velutipes. The specific method is: spray rare earth solution once every 3 days, spray 500ml per square meter of mushroom bed each time, and spray clear water every day to maintain relative humidity, which can be harvested when the mushroom body grows to meet the standard. The production practice shows that the concentration of rare earth solution containing 200 mg rare earth per liter is the best, the mycelium grows neatly, sturdily, and the biological benefit is the highest, up to 88.3%, and the protein content of Flammulina velutipes is as high as 30.3%. However, if the concentration is more than 200 mg per liter of rare earth, it is disadvantageous to the growth of Flammulina velutipes.
