摘　　要：研究分别以珍珠岩、菌种、猪粪作为添加料,对菇渣静态垛好氧发酵效果的影响。结果表明,菇渣+猪粪处理50℃以上的高温维持时间更长,挥发性固体(VS)和C/N下降幅度更高,有利于菇渣好氧发酵达到腐熟的状态。堆体内温度出现层次效应,高温发酵阶段下层温度高于中层温度,稳定阶段中层温度高于下层,堆体上层温度始终低于中下层。Effect of different additives which were perlite, strain, and swine manure on aerobic fermenta- tion of mushroom residue was studied in static piles. The results showed that the mushroom residue ＋ swine manure compost was beneficial to maturity of mushroom residue compost, the time maintaining above 50℃ was much longer, VS and C/N reduced with more extent. The temperature appeared stratified effects in the pile, the temperature of middle-layer was lower than the temperature of under-layer at the high temperature period, and the former was higher at the stable period, the temperature of upper-layer is always lower than that of middle and under layers at the composting process.
