茶梗、茶枝屑代料对黑木耳生长及品质的影响

Effects of Tea Stalks and Tea-branch Dust on Growth and Quality of Auricularia auricular

对比分析黑木耳在茶梗、茶枝屑不同基质配方上的菌丝生长、出菇表现、产量及营养成分。结果表明:黑木耳在各基质配方上均能正常生长、出菇,除配方CG1(78.5%茶梗)、CZ1(78.5%茶枝屑)产量及生物学效率低于对照CK(78.5%杂木屑)外,其他均高于CK,其中配方CZ2(48.5%茶枝屑)最高,生物学效率比CK高出10.09%;含茶枝屑配方栽出的黑木耳粗蛋白、粗脂肪、粗纤维、Ca、Fe、Zn、总氨基酸、必需氨基酸等营养成分均高于CK,而含茶梗配方栽出的黑木耳则是粗蛋白、粗多糖、灰分高于CK。综上所述,茶梗、茶枝屑作为代料栽培黑木耳可行,茶枝屑代料栽培出的黑木耳总体品质要优于茶梗代料。

The mycelial growth,primordia formation,yield and nutritional components of Auricularia auricula on different matrix formulations of tea stalks and tea-branch dust were compared and analyzed.The results showed that Auricularia auricula could normally grow and produce mushrooms in all matrix formulations,except that the yield and biological efficiency of formulations CG1(78.5%tea stalks)and CZ1(78.5%tea-branch dust)were lower than CK(78.5%mixed sawdust),the others were higher than CK,among which formulation CZ2(48.5%tea-branch dust)was the highest,with the biological efficiency 10.09%higher than CK.Nutrients such as crude protein,crude fat,crude fiber,Ca,Fe,Zn,total amino acids,essential amino acids and the like of Auricularia auricula cultivated in formulawith tea branch dust were higher than CK,while those of Auricularia auricula cultivated in formula with tea stalks were higher than CK in crude protein,ash content.In summary,tea stalks and tea-branch dust as substitutes to cultivate Auricularia auricula was feasible,while the overall quality of Auricularia auricula cultivated with tea-branch dust substitutes was better than that of tea stalks substitutes.
