How to grow oyster mushrooms for higher yields? These six tips are very practical

First, casing soil. After the mycelium has grown throughout the substrate, cover the mushroom bed with 1 cm of sandy loam soil, which generally increases the yield by about 10%. Insert-sheet stimulation: after the mycelium of the mushroom bed is fully grown, 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. During the young bud stage, spray with 0.001‰ triacontanol, which can increase the yield by 10%-15%. Spray once with 0.5‰ ethephon solution at the oyster mushroom bud stage, young mushroom stage and cap expansion stage, per square

Second, hormone stimulation. During the young bud stage, spray with 0.001‰ triacontanol, which can increase the yield by 10%-15%. Spray once with 0.5‰ ethephon solution at the oyster mushroom bud stage, young mushroom stage and cap expansion stage, 50 ml per square meter each time, which can promote budding and early maturity and 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, and 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), combine 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 bud formation stage, which can promote the formation and enlargement of fruiting bodies and increase the yield by 20%-30%.

Fifth, spray a 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 accelerate mycelial growth, speed up the transition between flushes after fruiting, promote uniform maturity and produce plump, firm mushrooms, and can increase the yield by 30%-70%.

Sixth, cover with plant ash. When oyster mushrooms are sown in early spring, the temperature is low, mycelial development is slow and contamination by weed molds is easy. Sprinkling 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 weed molds, helping mushrooms to emerge earlier and increasing the yield by about 10%.
