Pleurotus cornucopiae 608 was grown on a mixture of pasteurized cottonseed hulls (75% dry wt). 24% chopped wheat straw, and 1% ground limestone. The substrate was spawned at various levels (1.25%, 2.5%, 3.75%, or 5% wet wt) and not supplemented or supplemented with commercial delayed release nutrient (Campbell's S-41) at various levels (0%, 3%, 6%, 9%, or 12%). Maximum yield (weight of fresh mushrooms harvested at maturity) was obtained at 3.75-5% spawn level and 6% S-41 supplement. As supplement levels exceeded 6%, yields declined significantly. There was a negative correlation (r=-0.81) between spawn rate and days to production. As the spawn rate increased, the number of days to production decreased. By using a spawn rate of 3.75% of the wet substrate wt, it was possible to reduce the time to production by a mean of 9.2 days compared with a spawn rate of 1.25%.
平菇608在由经过巴氏杀菌的棉籽壳（75%干重）、24%切碎的小麦秸秆和1%石灰石粉组成的混合物上生长。该基质以不同水平（1.25%、2.5%、3.75%或5%湿重）接种，并分别在不同水平（0%、3%、6%、9%或12%）不添加或添加商业缓释营养素（金宝汤S-41）。在接种水平为3.75%-5%且S-41添加量为6%时获得了最高产量（成熟时收获的新鲜蘑菇重量）。当添加水平超过6%时，产量显著下降。接种率与出菇天数之间存在负相关（r = -0.81）。随着接种率的增加，出菇天数减少。与1.25%的接种率相比，使用占湿基质重量3.75%的接种率，平均可将出菇时间缩短9.2天。
