Perilla is an edible medical plant with rapidly increasing acreage in China. In this study, we investigated the potential of perilla stalks (PSs) as an alternative substrate for the cultivation of oyster mushrooms (). was cultivated on cottonseed hulls (CSH) alone or mixed with PSs in different ratios. The production parameters, physical characteristics, nutritional values, and antioxidant activity of mushrooms cultivated on different substrate mixtures were determined. The addition of PSs to CSH significantly improved the growth rate, yield, biological efficiency, and proximate composition and shortened the cultivation cycle. Cultivation on PSs alone increased the amino acid content in fruiting bodies and the antioxidant activity of mushroom extracts. The PS75 (25% CSH + 75% PS) substrate was deduced to be the most effective substrate on the basis of yield and biological efficiency obtained in a large area where perilla had been planted. The results demonstrate that mixtures of PS with CSHs could be used as novel, practical, and easily accessible alternative substrates for cultivation.
紫苏是一种可食用的药用植物，在中国种植面积迅速增加。在本研究中，我们调查了紫苏茎（PS）作为栽培平菇替代基质的潜力。平菇在单独的棉籽壳（CSH）上或与不同比例的PS混合的基质上进行栽培。测定了在不同基质混合物上栽培的蘑菇的生产参数、物理特性、营养价值和抗氧化活性。在CSH中添加PS显著提高了平菇的生长速率、产量、生物学效率和近似成分，并缩短了栽培周期。单独在PS上栽培增加了平菇子实体中的氨基酸含量和蘑菇提取物的抗氧化活性。根据在大面积种植紫苏的地区获得的产量和生物学效率推断，PS75（25%CSH + 75%PS）基质是最有效的基质。结果表明，PS与CSH的混合物可作为平菇栽培的新型、实用且易于获取的替代基质。
