咖啡渣栽培灵芝试验

Experiment on using coffee grounds for Ganoderma lingzhi cultivation

利用咖啡渣代替部分棉籽壳栽培灵芝的试验结果,培养基中添加10%~70%的咖啡渣,灵芝菌丝长势均较好,且都能正常出芝。其中以咖啡渣50%,棉籽壳49%,石膏1%,含水量60%的配方所产的子实体商品性较好,优于对照和其余3种配方,其菌盖直径9.43 cm、单芝鲜重48.25 g、总糖含量0.52%。利用咖啡渣栽培灵芝,不仅可以＂变废为宝＂,而且能提高产品多糖含量。

Studies were carried out to evaluate the feasibility of using coffee grounds as substrates to cultivate Ganoderma lingzhi. The result showed that the mycelium and fruit body growth well in substrates contented 10%~70% coffee grounds. And the substrate T3（coffee rounds 50%, cotton seed hull 49%, gypsum 1%, water content 60%） has better yields and quality（fruit cap diameter 9.43 cm, single fruit body fresh weight 48.25 g, total sugar content 0.52%）. Using the coffee grounds to cultivate Ganoderma lingzhi, not only can make full use of the coffee residues, but also can improve total sugar content in the Ganoderma lingzhi product.
