【摘要】 为实现蘑菇渣的资源化利用,采用7种常见腐熟微生物菌株,研究了不同微生物复配对蘑菇渣腐熟效果的影响。结果表明:处理组T₁₄（蜡状芽孢杆菌、巨大芽孢杆菌、甲基营养型芽孢杆菌、多黏类芽孢杆菌、绿色木霉和黑曲霉）与其他处理组相比具有更好的腐熟效果,发酵堆体温度最高达到63℃,≥55℃持续时间长达12 d,有效活菌数达0.26亿cfu·g^-1,均优于其他处理,pH值和色泽也达要求;腐熟后氮、磷、钾总养分均有显著提高,其中全氮含量提高了36%,达到21.1 g·kg^-1;全磷（P2O5）含量提高了66%,达到10.1 g·kg^-1;全钾（K₂O）含量提高了38%,达到25.9 g·kg^-1;有机质降解后含量降至585.4 g·kg^-1。植物种子萌发与生长试验表明,高羊茅和黑麦草的种子发芽指数（GI）均大于0.85,分别为1.21、1.14,高羊茅的茎长和地上鲜质量分别增加了24.4%和29.3%,黑麦草的茎长和地上鲜质量分别增加了33.3%和36.8%。蘑菇渣堆肥产品养分含量满足国家标准要求,能显著促进植物生长,是一种前景广阔的新兴有机肥产品,具有巨大的应用价值和广阔的市场前景。更多还原

【Abstract】 In order to realize the recycling use of spend mushroom compost, the experiment of 7 common decomposition microorganisms mixtures on the mushroom residue maturity were conducted in this study. The results showed that the group T₁₄ which included Bacillus cereus, Bacillus megatrium, Bacillus methylotrophicus, Paenibacillus polymyxa, Trichoderma viride, and Asprgillus niger had a better decomposition effect than others. There had three advantage about T₁₄:The duration over 55 ℃ were 12 days, the number of live bacteria could reach 2.6×10⁷ cfu·g^-1 and the pH value and color could be also qualified. There was a significant improvement about the nutrient contents after matured. The contents of TN,TP,TK were 21.1, 10.1 g·kg^-1 and 25.9 g·kg^-1 whichincreased 36%, 66%, and 38% respectively.The organic matter content reduced to 585.4 g·kg^-1 after degradation; The results of seed germination and growth test stated that the germination index（GI）of tall fescue seed and perennial ryegrass seed were 1.21 and 1.14, respectively（>0.85）. The stem length and the fresh weight of tall fescue and the perennial ryegrass were increased 24.4%, 29.3% and 33.3%, 36.8%, respectively.The nutrient content of the spent mushroom compost met the requirements of national standards, and significantly promoted plant growth. It was a promising organic fertilizer which had great application value and broad market prospects.更多还原
