Analysis of quality,yield and advantages of Stropharia rugosoannulata cultivated with sorghum straw
Using sorghum straw and corn cob as the main cultivation substrate raw materials to cultivate Stropharia rugosoannulata,the nutritional components of different sorghum straw content substrates and the effects of different culti-vation material ratio on the nutritional components and yield of the fruiting body were compared in the greenhouse.The results showed that compared with the control,the proportion of lignin,cellulose and reducing sugar in the matrix of sor-ghum straw replacing corn cob formula increased by 11.94%,12.55%,and 3.88%,respectively.The higher content of lignin,cellulose,and reducing sugar matrix is beneficial for the growth of Stropharia rugosoannulata and the utilization of its advantages in decomposing lignin.Compared with the control,the proportion of fat and reducing sugar in the fruiting body of Stropharia rugosoannulata cultivated with sorghum straw increased by 1.28%and 1.39%,respectively.When the amount of sorghum straw added reached 49%,the proportion of lignin and reducing sugar in the substrate increased by 6.36%and 1.44%,respectively.The polysaccharide content in the fruiting body showed no significant change,while the proportions of fat and reducing sugar content increased by 0.61%and 0.89%,respectively,and the yield of the first batch of mushrooms increased by 0.85 kg.Therefore,adding 49%sorghum straw is the optimum amount for greenhouse cultivation of Stropharia rugosoannulata.
