【摘要】 分析稻草营养品质及其对香菇菌丝生长的影响 ,探讨稻草硅酸盐成分阻碍香菇菌丝对稻草氮源和碳源营养的降解利用。结果表明 ,香菇菌丝在 2 0 1稻草培养基与麦麸培养基 (CK)上的生长速度差异不显著 ,分别为 0 .39cm· d- 1 和 0 .42 cm· d- 1 ;与汕优 6 3稻草 (0 .31cm· d- 1 )、 2 0 1稻穗 (0 .31cm· d- 1 )和 2 0 1稻叶 (0 .2 3 cm· d- 1 )培养基差异显著。稻草的硅酸盐物质在一定程度上阻碍香菇菌丝对稻草组织中蛋白质和纤维成分的降解利用。引进不同的香菇菌种作不同培养料的菌丝培养试验 ,初步筛选出适应性较广的香菇品种苏香 1号和 T89- 1更多还原

【Abstract】 Effect of nutritive quality of 201 and Shanyou 63 rice straw on mycelium growth of Lentinula edodes was studied,blocking effect of biogenic silicate against the biodegradation of N and C in rice straw was discussed as well. The growth rate of mycelium on medium of 201 rice straw was similar with that on wheat brain (CK) as 0 39 cm·d -1 and 0 42 cm·d -1 respectively,but significantly high than that on media of Shanyou 63 rice straw (0 31 cm·d -1 ), 201 rice head (0 31 cm·d -1 ) and 201 rice blade (0 23 cm·d -1 ). Biogenic silicate in rice straw showed a blocking effect on biodegradation of protein and fibrous nutrients in straw cell wall of Lentinula edodes mycelium.Two Lentinula edodes spp were selected from several species for their relatively wide adaptability.更多还原
