荆条基质下毛木耳培养条件优化

Culture Conditions Optimization for Auricularia polytrichain Vitex Chips

以毛木耳为试材,以荆条为基质,通过测定毛木耳在荆条屑培养基上的长速长势、胞外酶活性和生物学效率等指标,分析荆条作为毛木耳新型栽培原料的可行性。结果表明:荆条屑中纤维素含量为27.12%,半纤维素含量为10.06%,木质素含量为25.64%,粗蛋白质含量为3.35%,在栽培毛木耳方面具有可行性和开发潜力。以毛木耳3号为出发菌株,适宜栽培配方为荆条屑70%、棉籽皮10%、麸皮18%、生石灰1%、石膏1%。以毛木耳适宜料水比1∶1.4及采取适宜出耳模式与划口方式进行管理,其生物学效率可达103.75%。

Auricularia polytricha was used as test material,Vitex chips was used as matrix. Feasibility of Vitex chips used as a new cultivation material for Auricularia polytricha was analyzed by determinating of mycelium growth rate, extra cellular enzyme activities and biological efficiency of Auricularia polytricha based on Vitex chips. The results showed that in Vitex chips,the content of cellulose was 27. 12%;hemicellulose content was 10. 06 % ;lignin content was 25. 64 %, and crude protein content was 3. 35 %. Auricularia polytricha 3 was used as original strain, the suitable formula for Auricularia polytricha was Vitex chips, 70 %, cotton seed hulls 10 %, bran 18% ,lime 1%,gypsum 1%. Under the management of suitable material water ratio of 1 ： 1.4,under the suitable fruiting pattern and cutting method,the biological efficiency of Auricularia polytricha could reach 103. 75 %.
