How to make your oyster mushrooms high-yielding and good in quality. The following introduces some tips in this regard, for everyone's reference only:
First, earthing up. After the mycelium has grown through the substrate, cover the mushroom bed with a 1 cm thick layer of sandy loam, which can generally increase the yield by about 10%. Inserting pieces to stimulate the mushroom bed: after the mycelium has fully covered the bed, insert small wooden pieces, bamboo pieces, glass pieces or metal pieces into the mushroom bed, and within 1 week mushroom buds will emerge in large numbers along the inserted pieces.
Second, hormone stimulation. Spraying 0.001‰ triacontanol at the young bud stage can increase the yield by 10%-15%. Spraying 0.5‰ ethephon solution once each at the oyster mushroom bud stage, young mushroom stage and cap expansion stage, 50 ml per square meter each time, can promote budding and early maturity, and can increase the yield by about 20%.
Third, monosodium glutamate stimulation. Add 0.1% monosodium glutamate, 1% glucose and an appropriate amount of vitamin B1 to water, spray about 7 days after the first flush of mushrooms is harvested, spraying 0.5-1 kg per square meter, for a total of 3-4 sprays, which can increase the yield by 15%-2%.
Fourth, compound agent stimulation. Take 5 g of daminozide (B9), mix with 20 g of magnesium sulfate, 5 g of boric acid, 10 g of zinc sulfate, 250 mg of vitamin B1 and 50 g of urea, and add 50 kg of water to make a compound solution. Spray it on the surface of the substrate during the mushroom bud formation stage, which can promote the formation and enlargement of fruiting bodies and can increase the yield by 20%-30%.
Fifth, spraying trace element solution. After mushroom buds appear on the mushroom bed, spray a mixed trace element solution (ferric sulfate, zinc sulfate and potassium dihydrogen phosphate at 0.04% each), which can speed up mycelial growth, make the flushes turn over quickly after fruiting, make maturity uniform, and make the mushrooms plump and firm, and can increase the yield by 30%-70%.
Sixth, covering with plant ash. When oyster mushrooms are sown in early spring, the temperature is low, mycelial development is slow, and contamination by stray microorganisms is easy. Spreading a layer of plant ash on the surface can raise the bed temperature, promote mycelial development, provide nutrients for mycelial growth and inhibit the growth of stray microorganisms, which is conducive to earlier fruiting and can increase the yield by about 10%.
