| Summary: | 碩士 === 國立嘉義大學 === 園藝學系研究所 === 105 === The study ‘corncob crush and sugarcane bagasse were used as substitute substrate on cultivation of Pleurotus eryngii and Hypsizygus marmoreus’ were evaluated by pH and EC of mixed media, the growth of mycelia, the yield and mushroom quality. The yield of 100% sawdust PE bag were used as control, mixed media with 80% sawdust 20% corncob crush 20% rice bran, 60% sawdust 40% corncob crush 10% or 15% rice bran had higher yield of Pleurotus eryngii among all treatments. The results showed that corncob crush could substitute 20%-80% sawdust in mixed media, the yield could be promoted more than 40%-90% compared with the control . The treatments with corncob crush 40%-60% could obtain stable and high yield among all treatments. For this reason, corncob crush could substitute total or part of sawdust in Pleurotus eryngii production. Except the treatment with 80% sawdust 20% sugarcane bagasse 20% rice bran, the yield of other treatments were 50%-70% of that of control. Through sugarcane bagasse could substitute part of sawdust in Pleurotus eryngii production, but the yield may reduce 30%-50%.
Addition of rice bran in 100% sawdust PE bag, could promote the yield of Hypsizygus marmoreus. The treatments with 80% corncob crush 20% sawdust 10% or 15% rice bran, 60% corncob crush 40% sawdust 20% rice bran had higher yield among all the treatments, the results showed that corncob crush could substitute 40%-80% sawdust of mixed media in Hypsizygus marmoreus production. The higher the sawdust were, the less the Hypsizygus marmoreus fruiting body with diameter more than 2 cm were. the higher the corncob crush were, the more the Hypsizygus marmoreus fruiting body with diameter less than 2 cm were. Therefore, corncob crush could substitute total or part of sawdust in Hypsizygus marmoreus production. The treatments with 40% sugarcane bagasse 60% sawdust 20% rice bran, 40% sugarcane bagasse 60% sawdust 15% rice bran, 100% sawdust 20% rice bran, 20% sugarcane bagasse 80% sawdust 20% rice bran had higher yield among all the treatments, but 100% sugarcane bagasse 10% or 15% rice bran treatments had low yield and had significant difference with other treatments. the higher the sawdust were, the less the Hypsizygus marmoreus fruiting body with diameter more than 2 cm were. the higher the sugarcane bagasse were, the more the Hypsizygus marmoreus fruiting body with diameter less than 2 cm were. Treatments with 100% sugarcane bagasse 10% or 20% rice bran had higher yield in Hypsizygus marmoreus fruiting body with diameter less than 2 cm were, the lowest were treatments with 40% sugarcane bagasse 60% sawdust 10% rice bran, and treatments with sawdust content 80%-100%. Therefore, sugarcane bagasse could substitute part of sawdust (20%-80%) in Hypsizygus marmoreus production.
