木薯酒精渣适栽草菇品种筛选试验

目的]筛选适于木薯酒精渣栽培的草菇优良品种.方法]以木薯酒精渣为主料,棉籽壳、麸皮为辅料,采用全脱袋覆土出菇方式,对引进和分离的13个草菇品种进行出菇试验.结果]供试的13个草菇品种中菌丝生长速度较快的菌株有V97、V9、V25、V木和V112,菌丝日生长速度分别为15.43、14.86、13.57、12.78和12.78 mm/d;产量和生物转化率较高的菌株有V9、V木和V112,产量分别达29.16、21.70和18.21g/袋,生物转化率分别达24.50%、18.20%和15.30%;不易开伞的菌株为V9、V97、V365和草01.结论]初步筛选出V9作为木薯酒精渣的适栽草菇品种,并作为下一步扩大试验规模的出发菌株.

Preliminary study on screening optimum Volvariella volvacea varieties using cassava bagasse residue cultivation

【Objective】This research screened for elite Volvariella volvacea mushroom cultivation varieties using cassava bagasse residues. 【Method】Using cassava bagasse residue as the main ingredient and cottonseed hull and bran as secondary ingredients， 13 Volvariella volvacea varieties（strains） were produced through the whole bag mushroom removal fruiting method. 【Result】Out of the 13 tested varieties， those tested strains with rapid mycelium growth rate included V97，V9， V25， VMu， and V112， and the mycelial growth rates were 15.43， 14.86， 13.57， 12.78， and 12.78 mm/d， respectively. Those varieties with high production yield and biological conversion rate included V9， VMu， and V112， the corresponding production rate reached 29.16， 21.70， and 18.21 g/bag， and the  biological conversion rate reached 24.50%， 18.20%， and 15.30%， respectively. The varieties exhibiting anti-mushroom surface opening characteristics included V9， V97， V365， and Chao 01. 【Conclusion】From the preliminary selection， the V9 mushroom variety was the suitable planting variety using cassava bagasse residue；it could be used as the starting strain for expanding the scale of related researches.
