工厂化栽培草菇适宜优质高产菌株的筛选与分析

摘要

山东省草菇栽培面积大,工厂化生产发展较快,但是适宜的优质高产菌株相对缺乏,常规菌株种性退化严重.本试验对初筛的6个草菇菌株以玉米芯为主要栽培基质进行品比优选试验.结果表明:V1172、VSD-1出菇较早,产量高,但子实体菌苞较薄,易开伞;V1296、V1295产量较高,长势好,出菇期集中,子实体菌苞较厚,商品性好;V9715、V选育10产量明显低于其它菌株,但V选育10子实体菌苞厚,耐储存.综合分析比较认为:V1296、V1295表现最佳,适宜山东工厂化栽培推广.%The cultivated area of Volvaria volvacea in Shandong Province is very large,and its industrialized production is developing fast.However,the good-quality and high-yield strains suitable for industrialized production are relatively lacking,and the characteristics of conventional strains degrade seriously.Six Volvaria volvacea strains selected through preliminary test were further compared with corncob as main cultivation substrate.The results showed that strains V1172 and VSD-1 had the characteristics of earlier sporophore forming and high yield,but thinner biofilm and easily opened pileus.The strains V1296 and V1295 had higher yield,good growth vigor,concentrated fruiting period,thick biofilm and good commercial characteristics.The yield of V9715 and V Xuanyul0 were significantly lower than that of the other strains,and V Xuanyu10 had thicker biofilm,which indicated storage stability.By comprehensive analysis,the strains V1296 and V1295 performed optimal,so they were suitable for industrial cultivation and popularization.
