摘　　要：为深入研究和开发合理的堆肥工艺,旨在实现苦参渣的资源化利用,从而降低药渣对环境的负面影响,并促进中药行业的绿色、循环和可持续发展。采用L 9(33)正交设计,研究物料的配比(苦参药渣与鸡粪、锯末配料比1∶1,1.5∶1,2∶1);初始pH值(7,8,9)、菌剂PN-8接种量(0.5%,1%,3%)对苦参渣堆肥产品质量的影响。以失重率、有机质降解率、纤维素降解率、半纤维素降解率、木质素降解率、种子发芽指数、总养分作为评价指标,并建立Z-score(Z值)法综合评价模型进行评价。结果表明:苦参∶鸡粪、锯末配料比2∶1、pH值为8、菌剂PN-8接种量为0.5%是苦参渣堆肥工艺最佳参数组合。该研究结果将为中药渣堆肥工业化生产,中药渣的可循环利用,以及生态环境保护提供指导。In order to conduct in-depth research and develop reasonable composting processes,this paper aims to achieve the resource utilization of Sophora flavescens residue,thereby significantly reducing the negative environmental impact of pharmaceutical waste,and promoting the green,circular,and sustainable development of the traditional Chinese medicine industry.In this study,effects of material ratio(Sophora flavescens residue,chicken manure,and sawdust mixed in ratios of 1∶1,1.5∶1,and 2∶1),initial pH value(7,8 and 9),and inoculum PN-8 dosage(0.5%,1%and 3%)on the quality of Sophora flavescens residue compost product were investigated by L 9(33)orthogonal design.The compost quality was evaluated using Z-score method comprehensive evaluation model which established by weight loss rate,organic matter degradation rate,cellulose degradation rate,hemicellulose degradation rate,lignin degradation rate,seed germination index,total nutrients as evaluation indicators.The results showed that the optimal parameter combination for the composting process of Sophora flavescens residue was a material ratio of 2∶1(Sophora flavescens residue:chicken manure and sawdust),a pH value of 8,and an inoculation amount of PN-8 inoculum of 0.5%.The results of this study will provide guidance for the industrialized production of composting of Chinese medicinal residue,the recyclable utilization of Chinese medicinal residue,and the protection of the ecological environment.
