【中文摘要】 本研究采用玉米秸秆和棉籽皮按 1∶1混合且无需发酵袋栽平菇的方法 ,生物学效率可高达 145 % ,污染率为零 ,菌丝增长符合逻辑斯第曲线 ,总体生长速度均超过纯棉籽皮。含玉米秸秆 5 0 %、玉米秸秆长度为 1～ 2cm的处理在中后期一直属于速度最快的。纯棉籽皮处理菌丝长满时间最长 ,含玉米秸秆 1～ 2cm的处理菌丝长满时间均比 3～ 4cm的短。含玉米秸秆的处理子实体生长速度的高峰期均比棉籽皮滞后 ,出菇期较长。除纯棉籽皮对照外 ,含 5 0 % 1～ 2cm玉米秸秆的处理的籽实体的生长速度高峰值最高 ,且到达峰值的时间比对照滞后约 2d。子实体产量增长符合指数增长曲线
【英文摘要】 In this study,there is no contamination in the formula used to cultivate Pleurotus ostreatus without fermentation using maize straw.The growth of hypha was in accordance with logistic curve.The general growth rates in the treatment containing maize straw were higher than those of pure cotton seed peel.The treatment containing 50% maize straw with its length 1～2cm was the fastest in the middle and later stage.In the treatment containing pure cotton seed peel,the time for full hypha growth is the longest but it is shorter in the treatment containing 1～2cm maize straw than that of 3～4cm.
