摘要
为了研究不同物理添加剂对尾菜好氧堆肥的影响,同时为复合物理添加剂提高尾菜好氧堆肥效率并减少潜在的环境污染提供参考,该试验使用白菜尾菜为堆肥原料,水稻秸秆为调理剂,添加了麦饭石、生物炭及两者的混合物作为物理添加剂,通过好氧堆肥方式,探究不同物理添加剂对白菜尾菜好氧堆肥的影响。添加麦饭石、生物炭以及混合物能够提高堆体温度、增加高温阶段时间、提升pH,降低含水率下降程度,有利于微生物对堆体有机质的降解,同时提高种子发芽指数,使堆肥产物处于腐熟状态,无害化。结果表明:添加麦饭石、生物炭和混合物的效果比单一添加麦饭石、生物炭更好。物理添加剂能够提高尾菜好氧堆肥效率,而复合物理添加剂则更能促进好氧堆肥过程并提高堆肥品质。
To study the effects of different physical additives on the aerobic composting of tail vegetables,and to provide a reference for improving the efficiency of the aerobic composting of tail vegetables and reducing potential environmental pollution by composite physical additives,this experiment used cabbage tail as compost raw material,rice straw as a conditioner,and added medical stone,biochar,and their mixture as physical additives.The effects of different physical additives on the aerobic composting of cabbage tails were studied.The addition of medical stone,biochar,and mixture can increase the temperature of the pile,increase the time of the high-temperature stage,increase the pH,and reduce the decrease of water content,which is conducive to the degradation of the organic matter of the pile by microorganisms,and improve the seed germination index so that the compost products are in a state of decomposition and harmless.The results showed that the effect of adding medical stone,biochar,and the mixture was better than that of adding only medical stone and biochar.Physical additives could improve the efficiency of aerobic composting,while compound physical additives could promote the process of aerobic composting and improve the quality of composting.
