不同原料基质栽培平菇的生物学

以木屑、棉籽壳、玉米芯及麦草为基质材料，采用单纯形格子试验设计方法，通过分析不同基质对平菇菌丝生长速度、生物学效率和投入产出比的影响，优化平菇栽培配方。结果表明，4种原料对菌丝生长速度、生物学效率和投入产出比的影响非简单的线性关系，棉籽壳和玉米芯互作与平菇生物学效率和投入产出比具显著正效应。获得优化的栽培基质配方为棉籽壳53%、玉米芯34%、麸皮10%、石灰2%及石膏1%。验证试验结果表明，优化配方的增产效果显著，较目前普遍应用的纯棉籽壳配方平均增产25.14%。

Biology Research of Pleurotus ostreatus Cultivated in Different Raw Materials

Hyphae of Pleurotus ostreatus were cultured in different substrates,such as sawdust,cotton seed shells,corn cobs and wheat straw to study their influences on the hypha growth speed,biological efficiency and input-output ratio.Simplex-lattice design was adopted.The formula was optimized.The results indicated that four kinds of raw materials had significant non-linear impacts on the hypha growth speed,biological efficiency and input-output ratio.Cotton seed shells and corn cobs exhibited significantly positive impacts on the biology efficiency and input-output ratio.The optimal cultivation formula was obtained as corn cobs 53%,cotton shell 34%,bran 10%,lime 2%,and gypsum 1%,by which the yield increased by 25.14% compared with pure cotton seed shells.
