Abstract: The Auricularia auricula ’Heiwei No.15’ was used as the test material,the different proportion of Salix integra sawdust instead of Quercus mongolica sawdust were used as the culture medium of Auricularia auricula.The effects of different formulas on mycelial growth,fruiting body growth,biological transformation rate,yield and economic benefits of Auricularia auricula were studied,in order to provide reference for the application of Salix integra sawdust.The results showed that the addition of sawdust had no significant effect on mycelium growth rate,but had significant effect on fruiting body growth.The total yield of Auricularia auricula decreased with the increase of Salix integra sawdust,however,the biological conversion rate increased with the increase of Salix integra sawdust.Based on the analysis of the comprehensive economic benefit,the formulas Z1 and Z2were the most suitable ones for the cultivation of Auricularia auricula.It was feasible to replace Quercus mongolica sawdust by adding no more than 40.0% of Salix integra sawdust.
