研究了在稻草和麦秸上不添加营养物质栽培平菇的效果。确定了稻草粉碎方法和粒度、菌种接种水平以及基质类型（稻草与麦秸）对蘑菇产量、生物效率、生物转化效率和基质降解的影响。对粉碎和切碎两种粉碎方法进行了比较。秸秆粉碎比秸秆切碎产生更高的蘑菇生长速率和产量。蘑菇的生长周期与地面的基板是五天短于切碎的稻草为类似的颗粒大小。然而，人们发现，当稻草被磨成太小的颗粒时，蘑菇产量就会下降。在三个菌种水平（12%、16%和18%）下，12%水平导致蘑菇产量显著低于其他两个水平。稻草与麦秸相比，在相同的栽培条件下，稻草的蘑菇产量比麦秸高10%左右。出菇后基质干物质损失率为30.1%~ 44.3%。真菌利用后剩余的秸秆纤维不像原始秸秆纤维那样可降解，表明真菌发酵没有提高秸秆的饲料价值。(C)2002爱思唯尔科技有限公司。保留所有权利。
Cultivation of the oyster mushroom, Pleurotus sajor-caju, on rice and wheat straw without nutrient supplementation was investigated. The effects of straw size reduction method and particle size, spawn inoculation level, and type of substrate (rice straw versus wheat straw) on mushroom yield, biological efficiency, bioconversion efficiency, and substrate degradation were determined. Two size reduction methods, grinding and chopping, were compared. The ground straw yielded higher mushroom growth rate and yield than the chopped straw. The growth cycles of mushrooms with the ground substrate were five days shorter than with the chopped straw for a similar particle size. However, it was found that when the straw was ground into particles that were too small, the mushroom yield decreased. With the three spawn levels tested (12%, 16% and 18%), the 12% level resulted in significantly lower mushroom yield than the other two levels. Comparing rice straw with wheat straw, rice straw yielded about 10% more mushrooms than wheat straw under the same cultivation conditions. The dry matter loss of the substrate after mushroom growth varied from 30.1% to 44.3%. The straw fiber remaining after fungal utilization was not as degradable as the original straw fiber, indicating that the fungal fermentation did not improve the feed value of the straw.
