青贮苎麻副产物栽培刺芹侧耳技术研究

Application of silage ramie byproducts for Pleurotus eryngii cultivation

针对食用菌培养基质严重短缺和苎麻副产物直接晾晒干燥成本高、体积大、不便于长途运输等问题,进行青贮苎麻副产物栽培刺芹侧耳试验。通过测定不同营养条件下刺芹侧耳的菌丝生长速率和生物学效率,确定了青贮苎麻副产物培养基栽培刺芹侧耳的适宜配方,并对产品品质进行了检测。结果表明:培养基pH为5.5,培养基中含苎麻副产物50%和水分67.5%,并添加1%碳酸钙和1%白糖时栽培刺芹侧耳的效果较好,生物学效率达70%以上;与常规棉籽壳培养基相比,青贮苎麻副产物培养基栽培产品的蛋白质含量提高了30%,总糖和脂肪含量分别降低了24%和33%。

Faced by issues in the mushroom cultivation, such as substrates shortage, high cost and large volume in direct air-dry or inconvenient long-distance transportation, silage ramie byproducts were tested for Pleurotus eryngii cultivation in this study. The effects of moisture, pH, calcium salts, sugars, additives, and carbonitride on the Pleurotus eryngii growth were measured from mycelial growth rate and biological efficiency. The optimal medium conditions of the silage ramie byproducts and mushroom residues for eryngii cultivation as well as the product quality were also determined. The results showed that the when the cultivation medium contained 50% silage ramie byproducts, 35% nitrogen source, 67.5% moisture content, 1% calcium carbonate and 1% sucrose with a 5.5 pH value, the biological efficiency of Pleurotus eryngii could reach up to 70% above; Compared with the cotton seed hulls medium cultivation, the protein content of the Pleurotus eryngii was increased by 30% and the total sugar and fat were reduced by 24% and 33%, respectively. This study demonstrated that the silage ramie byproduct should be a good raw material for Pleurotus eryngii cultivation.
