茶枝屑代料栽培黑木耳配方

Formula of Cultivating Auricularia auricula With Tea-branch Dust as Substitute

以废弃的茶枝条为黑木耳的栽培原料,通过添加不同比例的茶枝屑,研究不同比例茶枝屑配方对黑木耳栽培中菌丝、耳基、子实体生长情况、产量及营养品质的影响,旨在探索利用茶枝屑栽培黑木耳的可行性,为废弃茶枝条的资源化利用提供参考依据。结果表明:配方2单产最高为40.83 g,菌丝生长速度最慢为2.69 mm·d^(-1),子实体最密集,朵形偏小;配方1单产为36.97 g,菌丝生长速度为3.01 mm·d^(-1),子实体较稀疏,朵形中等;配方3单产为36.7 g,菌丝生长速度为3.03 mm·d^(-1),长势较密集,朵形较大;CK的单产最低为35.27 g,菌丝生长速度为3.01 mm·d^(-1),子实体稀疏。在营养价值方面CK最低,配方3粗蛋白和粗多糖含量最高,分别为18.07%和4.80%;配方1粗纤维和灰分含量最高,分别为6.59%和3.83%。

The waste tea branches were used as the raw materials for cultivation of Auricularia auricula,and the effects of different proportions of tea-branch dust on the growth,yield and nutritional quality of hypha,ear base and fruiting body in cultivation of Auricularia auricula were studied,in order to explore whether tea-branch dust was feasible to cultivate Auricularia auricula,and to provide reference for the resource utilization of waste tea branches.The results showed that yield of formula 2 was the highest with 40.83 g,but the mycelial growth rate was the slowest,just with 2.69 mm·d^(-1),the fruiting body was the densest and the flower shape was smaller.The yield of formula 1 was 36.97 g,the mycelial growth was 3.01 mm·d^(-1),the fruiting body was sparse and the flower shape was medium;the yield of formula 3 was 36.7 g,and the mycelial growth was 3.03 mm·d^(-1),with dense growth and large flower shape;the yield of CK was the lowest,just with 35.27 g,the mycelial growth was 3.01 mm·d^(-1),and the fruiting body was sparse.The nutritional value of CK was the lowest,the content of crude protein and crude polysaccharide of formula 3 were the highest,which were 18.07% and 4.80% respectively;the crude fiber and ash content of formula 1 were the highest,which were 6.59% and 3.83% respectively.
