通过研究不同腐熟菌剂对黑木耳菌渣堆肥腐熟效果的影响，筛选出适宜西北地区黑木耳菌渣发酵的腐熟菌剂。对黑木耳菌渣添加5种不同腐熟剂进行高温堆肥，研究不同腐熟菌剂对黑木耳菌渣发酵温度、水分、化学成分和种子发芽指数的影响。结果表明，接种不同腐熟菌剂均能不同程度缩短黑木耳菌渣料堆升温时间，加速堆体水分的下降，显著降低料堆的碳氮比，提高黑木耳菌渣料堆粗纤维的降解率，显著提高料堆的种子发芽指数和EC值。总体来说，黑木耳菌渣添加洛阳欧克生物科技有限公司、济宁世合生物有限公司和北京裕丰力多金肥业有限公司的腐熟菌剂堆肥腐熟效果更好。

This study evaluated the effects of various decomposition agents on the decomposition of Auricularia auricula residue, aiming to identify inoculants suitable for fermenting Auricularia auricula residue in northwestern region. By adding 5 different inoculants to the residue and conducting high-temperature compost, this study examined how each inoculant affected compost through fermentation temperature, moisture levels, chemical composition, and the seed germination index. The results indicated that using these inoculants significantly reduced the time period for heating, accelerated water loss, lowered the carbon/nitrogen ratio, increased the degradation rate of coarse fiber, and enhanced both the seed germination index and electrical conductivity (EC) of the Auricularia auricula residue compost. In summary, inoculants from Luoyang Okobaike Biotechnology Co., Ltd., Jining Shihe Biotechnology Co., Ltd., and Beijing Yufengliduo Fertilizer Co., Ltd., demonstrated the most effective results for Auricularia auricula residue composting.
