The optimal substrate formulation for cultivation seed production consisted of 65% pine sawdust， 10% wheat grain， 20% wheat bran， 2.5% corn flour， 1% gypsum powder， 1% sucrose， 0.2% potassium dihydrogen phosphate， and 0.3% magnesium sulfate. Increasing the amounts of pine sawdust and corn flour in moderation is beneficial for mycelial growth and improves the strain quality.
