Abstract:
Four different particle sizes of corn cobs were used as test materials for pile fermentation.The differences in physical and chemical properties of the pile were studied by using corresponding national and local standard measurement methods,in order to screen out the suitable range of corn cob particle sizes for cultivation of mushroom fermentation materials.The results showed that for fermentation materials with particle sizes of 0.2-0.5 cm and 0.5-1.5 cm,the highest fermentation temperature was maintained at 70-80 ℃.At the end of fermentation,the carbon nitrogen ratio was 37.9 and 39.2,the pH was 7.32 and 7.37,the water holding coefficient was 3.39 and 3.32,and the water content was 62.7% and 61.1%,respectively.The fermentation materials with corn cob particle sizes of 1.5-2.5 cm and 2.5-3.5 cm were kept at a maximum fermentation temperature of 50-60 ℃.At the end of fermentation,the carbon nitrogen ratio was 44.5 and 46.2,respectively,with pH values of 8.52 and 8.49,water holding coefficients of 3.22 and 3.18,and water content of 56.4% and 53.8%,respectively.Fermented materials with particle sizes of 0.2-0.5 cm and 0.5-1.5 cm were more favorable for the rapid growth of Pleurotus ostreatus hypha and the improvement of Pleurotus ostreatus yield,making them suitable as the main raw materials.
