摘要: 以不同比例牧草与沼渣替代木屑栽培毛木耳对其产量、品质及氨基酸含量影响各异。30%草粉 +30%沼渣替代木屑效果较好，生物效率为107.5%，产量比对照高82.2%，粗蛋白、氨基酸、粗脂肪、可溶性糖含量分别比对照高3.7%、1.75%、0.13%、0.37%；以50%草粉或沼渣替代木屑其毛木耳产量分别比对照高55.1%和61.0%。山地果园连续3年施用5t/hm2沼渣、5t/hm2菌渣和5t/hm2鲜草处理区与对照相比，其红壤中腐殖酸碳含量分 别提高22.9%、26.5%和16.5%；红壤中团粒结构依次提高78.5%、79.9%和69.3%，改良土壤效果较好。Abstract: The results indicate that different proportions of forage and biogas residues substituted for wood pieces have various effects on yield and quality of A.polytricha.The better one is substituted 30% of grass power and 30% of biogas residues for wood pieces,and its biological efficiency is 107.5%,the yield is increased by 82.2%,crude protein,aminoacid,crude fat and soluble sugar increased by 3.7%,1.75%,0.13% and 0.37% respectively.The yield is increased by 55.1% and 61.0% respectively when 50% of grass power or biogas residues substitute for wood pieces.As compared with CK,the carbon in humic acid of red soil is increased by 22.9%,26.5%,16.5% respectively by all applying 5t/hm2 of biogas residues,fungi residues and fresh grass in orchard for three years.The granular structure is enhanced by 78.5%,79.9% and 69.3% respectively.
