摘要：为研究毛竹竹屑作为代替基质在玉木耳栽培中的应用潜力及其对产品品质的影响,该研究创新性地设计了9种不同比例的毛竹竹屑配方,并以常规木屑配方(CK)为对照,采用方差分析和主成分分析对不同配方玉木耳菌丝性状、子实体农艺性状、营养价值、药用价值和经济效益进行综合评价。结果表明,与配方CK相比,配方A(20%竹屑、20%木屑、25%棉籽壳、25%麦麸、8%黄豆粉、1%石灰、1%石膏,均为质量分数)可缩短菌袋满袋时间,加快菌丝生长速度;农艺性状方面,配方A显著提高玉木耳子实体产量和生物学效率;营养价值方面,配方A总糖和粗蛋白含量略高于CK,总氨基酸含量显著低于CK;药用价值方面,配方A总黄酮和麦角甾醇含量显著高于CK,总多糖和总酚含量略高于CK;主成分分析结果表明,配方A综合得分最高;经济效益分析表明,配方A最好,菌袋成本为1.51元/包,净收益为8.72元/袋,毛竹林下玉木耳菌包放置密度30000包/hm^(2),净收入可达261000元/hm^(2)。综上,毛竹竹屑可以替代部分木屑栽培玉木耳,其中20%竹屑、20%木屑、25%棉籽壳、25%麦麸、8%黄豆粉、1%石灰、1%石膏可提高玉木耳产量、营养价值和药用价值,降低生产成本,提高经济效益。
To explore the potential of using moso bamboo sawdust as a substitute substrate in the cultivation of Auricularia cornea and its impact on product quality,this study innovatively designed nine different formulations with varying proportions of moso bamboo sawdust.A conventional wood sawdust formulation(CK)was used as the control.Variance analysis and principal component analysis(PCA)were employed to comprehensively evaluate the mycelial traits,agronomic traits of fruiting bodies,nutritional value,medicinal value,and economic benefits of A.cornea under different formulations.Results showed that,compared to CK,Formulation A(20%bamboo sawdust,20%wood sawdust,25%cottonseed hull,25%wheat bran,8%soybean meal,1%lime,and 1%gypsum)shortened the time required for full colonization of the cultivation bags and accelerated mycelial growth.In terms of agronomic traits,Formulation A significantly increased the yield and biological efficiency of A.cornea fruiting bodies.Regarding nutritional value,the total sugar and crude protein content in Formulation A were slightly higher than CK,while the total amino acid content was significantly lower than CK.For medicinal value,the total flavonoid and ergosterol content in Formulation A were significantly higher than CK,while the total polysaccharide and total phenol content were slightly higher than CK.PCA results indicated that Formulation A had the highest comprehensive score.Economic analysis revealed that Formulation A was the most cost-effective,with a cultivation bag cost of 1.51 RMB per bag and a net profit of 8.72 RMB per bag.Under a density of 30000 bags per hectare in moso bamboo forests,the net income could reach 261000 RMB per hectare.In conclusion,moso bamboo sawdust can partially replace wood sawdust in the cultivation of A.cornea.The formulation with 20%bamboo sawdust,20%wood sawdust,25%cottonseed hull,25%wheat bran,8%soybean meal,1%lime,and 1%gypsum can improve yield,nutritional value,and medicinal value of A.cornea,reduce production costs,and enhance economic benefits.
