Seven methods of applying nutrient solutions to increase oyster mushroom yields

One, sucrose and calcium carbonate phosphate mixed solution: sucrose 1%, calcium carbonate 1%, potassium dihydrogen phosphate 0.1%. Use when the mycelium has covered the mushroom bed and before fruiting bodies appear.

Two, urea and citric acid mixed solution: urea 0.5%, citric acid 0.1%, adjust pH to 7 with sodium hydroxide. Use after the first flush of mushrooms is harvested. Using it after the second flush is not effective and instead hinders oyster mushroom growth.

Three, sugar, urea and citric acid mixed solution: sucrose, citric acid and urea 1% each, adjust pH to 7. It has the same effect as the previous two nutrient solutions.

Four, ethanol, ammonium phosphate and vitamin C solution: ethanol 2%, ammonium dihydrogen phosphate 0.1%, vitamin C 0.02%. Use during the mushroom bud stage; it can improve mushroom quality, with large caps, thick flesh and thick stems. Use with caution in hot, stuffy weather, otherwise dead buds and dead mushrooms easily occur.

Five, monosodium glutamate and sucrose mixed solution: sucrose 1%, monosodium glutamate 0.06%. After cleaning the mushroom bed, sprinkle heavily with water; it can adjust the carbon-to-nitrogen ratio of the mushroom bed compost, induce mycelial recovery and growth, and speed up the flush transition and mushroom production.

Six, synthetic nutrient solution: urea 0.3%, sucrose 1%, potassium dihydrogen phosphate 0.2%, magnesium sulfate 0.05%, borax 0.05%. Apply after dry cleaning the mushroom bed.

Seven, plant growth hormone solution: use a compound plant growth hormone, and before and after fruiting, spray with a 150-fold dilution. Fruit body differentiation can be advanced by 4-5 days, with a significant yield increase effect.
