Abstract

To explore the potential of using moso bamboo sawdust as a substitute substrate in the cultivation of Auricularia cornea and its impact on product quality, this study innovatively designed nine different formulations with varying proportions of moso bamboo sawdust.A conventional wood sawdust formulation (CK) was used as the control.Variance analysis and principal component analysis (PCA) were employed to comprehensively evaluate the mycelial traits, agronomic traits of fruiting bodies, nutritional value, medicinal value, and economic benefits of A.cornea under different formulations.Results showed that, compared to CK, Formulation A (20% bamboo sawdust, 20% wood sawdust, 25% cottonseed hull, 25% wheat bran, 8% soybean meal, 1% lime, and 1% gypsum) shortened the time required for full colonization of the cultivation bags and accelerated mycelial growth.In terms of agronomic traits, Formulation A significantly increased the yield and biological efficiency of A.cornea fruiting bodies.Regarding nutritional value, the total sugar and crude protein content in Formulation A were slightly higher than CK, while the total amino acid content was significantly lower than CK.For medicinal value, the total flavonoid and ergosterol content in Formulation A were significantly higher than CK, while the total polysaccharide and total phenol content were slightly higher than CK.PCA results indicated that Formulation A had the highest comprehensive score.Economic analysis revealed that Formulation A was the most cost-effective, with a cultivation bag cost of 1.51 RMB per bag and a net profit of 8.72 RMB per bag.Under a density of 30 000 bags per hectare in moso bamboo forests, the net income could reach 261 000 RMB per hectare.In conclusion, moso bamboo sawdust can partially replace wood sawdust in the cultivation of A.cornea.The formulation with 20% bamboo sawdust, 20% wood sawdust, 25% cottonseed hull, 25% wheat bran, 8% soybean meal, 1% lime, and 1% gypsum can improve yield, nutritional value, and medicinal value of A.cornea, reduce production costs, and enhance economic benefits.

Key words： Auricularia cornea; moso bamboo shavings; agronomic traits; nutritional value; medicinal value; principal component analysis; economic benefits
