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/hm^2沼渣、5t/hm^2菌渣和5t/hm^2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。
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.
