Effects of replacing cultivation with the combination of Pleurotus eryngii residue and waste bedding materials on yield and quality of Agaricus blazei
In order to explore the appropriate proportion of Pleurotus eryngii residue for Agaricus blazei cultivation,a cultivation bed experiment using P.eryngii residue and waste bedding material as substitutes for rice straw was conducted in this study to investigate the impact of different replacing ratios on the yield and nutritional quality of A.blazei J2 and J37.The results indicated that the fruiting body yield of A.blazei J2 and J37 initially increased and then decreased with an escalation in P.eryngii residue replacement.The optimal replacement ratio was found to be 30%,resulting the highest yields of 2.038 kg·m-2 and 2.267 kg·m-2 for A.blazei J2 and J37,respectively.The fruiting bodies of A.blazei were predominantly produced in the first and second tides.Notably,when cultivated with P.eryngii residues,the yield proportion in the first two tides exceeded that of conventional cultivation method.The contents of polysaccharide,crude protein,and amino acid in the fruiting body of A.blazei J2 and J37 decreased with an increase in tide times.However,the reduction amplitude for the treatment with P.eryngii residue replacement was smaller than that observed in conventional cultivation method.In comparison with conventional cultivation treatment,the contents of crude protein,amino acid,and polysaccharide in the fruiting body of A.blazei cultivated with P.eryngii residue increased by 2.42%-10.44%,4.09%-12.00%,and 11.07%-23.70%,respectively.The nutritional quality of A.blazei was optimal when the replacement ratio was 30%.The production cost analysis revealed that the cultivation cost of A.blazei with P.eryngii residues decreased by 35.08%-54.00%compared to conventional cultivation treatment.In conclusion,the appropriate replacement of P.eryngii mushroom residue and waste bedding material for the cultivation of A.blazei demonstrates higher and relatively stable quality yield across different tides.Additionally,it effectively reduces the cost of cultivation materials,leading to higher overall benefits.
