摘要
以4种不同配方灵芝培养基(木屑、常规菌草、巨菌草、巨菌草沼渣)及其菌糟为试材,采用国标法测定灵芝培养基及其菌糟中的粗蛋白质、粗脂肪、粗纤维、粗灰分和氨基酸含量,并利用苯酚硫酸法、国标法分别测定出芝后菌糟粗多糖、重金属含量。结果表明:4种灵芝菌糟营养丰富,粗蛋白质含量分别为8.86%、9.22%、12.40%、9.42%;粗多糖含量分别为3.0%、4.5%、4.7%、3.3%;4种菌糟所含氨基酸种类齐全,含量丰富;重金属含量在饲料卫生标准规定的范围内,且远低于有机肥料的标准。因此,4种灵芝菌糟在用作饲料及饲料添加剂、肥料、无土栽培基质等方面具有很大的开发潜力。
The crude protein,crude fat,crude fiber,crude ash and amino acids from mushroom culture medium and spent mushroom substrate were measured by national standard methods,while the contents of the polysaccharides and heavy metals in these substrates after Ganoderma lucidumcultivation were evaluated by phenol-sulfuric acid method and national standard method,respectively.The results showed that four spent Ganoderma lucidum substrates（sawdust,JUNCAO,JUJUNCAO and JUJUNCAO biogas residue）were rich in crude protein（8.86%,9.22%,12.4%and 9.42%）,crude polysaccharide（3.0%,4.5%,4.7%and 3.3%）.Amino acids were rich and varied in different substrates.The contents of heavy metals were in the prescribed of the feed hygiene standards,which were far lower than the standard of organic fertilizers.In a conclusion,the results indicated that four spent Ganoderma lucidumsubstrates could be used as feed additive selectively and had great potential for development in using as feed and feed additives,fertilizers and soilless culture substrate.
