摘　　要：为了提高香菇渣的好氧堆肥的发酵效率,本文设置了香菇渣与牛粪的不同配比,并引进了促发酵的复合菌剂。结果表明,香菇渣中添加30%比例的牛粪或添加10%以上的牛粪及复合菌剂均能显著促进菇渣堆温上升和腐熟发酵,从而提高菇渣的无害化处置效率。本试验中不同菇渣与牛粪配比高温堆肥发酵5天以后,基本上消除了物料毒性对种子发芽的影响。在堆肥过程中,物料pH和电导率(EC)均随着堆肥时间的延长呈现出先快速升高后逐步趋于平稳的态势。In this paper, in order to improve the fermentation efficiency of the aerobic composting of mush-room residue, different ratios of mushroom residue and cow manure were set up, and a composite microbial agent for promoting fermentation was introduced. The results showed that the addition of 30% cow dung or more than 10% cow dung and composite microbial agents to the mushroom resi-due significantly promoted the temperature rise and maturation fermentation of the mushroom residue, thereby improving the efficiency of harmless disposal of mushroom residue. After 5 days of high-temperature composting with different ratios of mushroom residue and cow manure in this experiment, the effect of material toxicity on seed germination was basically eliminated. During the composting process, both the pH and conductivity of the material showed a rapid increase and then gradually stabilized trend with the extension of composting time.
