选用菇渣与鸡粪为原料进行高温好氧堆肥,研究了不同促腐剂对菇渣-鸡粪混合物的腐熟过程及腐熟效果的影响。结果表明:接种促腐剂后,经发酵腐熟的菇渣-鸡粪混合物理化性质均得到一定改善,具体表现为堆肥升温加快,超过55℃高温腐熟天数增加,有机碳含量显著下降,氮、磷和钾累积养分明显增加;其中,接种B2菌剂的处理腐熟效果最好。经过发酵腐熟后,菇渣-鸡粪混合物中的重金属含量增加显著,但均符合NY 525—2012有机肥料标准限量要求,可以直接施用。
Mushroom residue and chicken manure were selected as raw materials for high-temperature aerobic composting. Effects of different promoters on maturation and maturity of Mushroom residue-chicken manure mixture were studied. The results showed that the physical and chemical properties of Mushroom residue - chicken manure mixture after fermentation were all improved. The results showed that the composting temperature increased faster, the number of rotting days increased more than 55 ℃, the content of organic carbon decreased significantly, and the contents of nitrogen and phosphorus And potassium accumulated nutrients increased significantly; Among them, the inoculation of B2 fungi treatment of decomposing the best. After fermenting and maturing, the content of heavy metals in mushroom residue-chicken manure mixture increased significantly, but all met the limit requirement of NY 525-2012 organic fertilizer standard and could be applied directly.
