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L9(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.
Abstract
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 environ-mental impact of pharmaceutical waste,and promoting the green,circular,and sustainable development of the tra-ditional Chinese medicine industry.In this study,effects of material ratio(Sophora fllavescens residue,chicken ma-nure,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 L9(33)orthogonal design.The compost quality was evaluated using Z-score method comprehensive evaluation mod-el 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 re-sults 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 industrial-ized production of composting of Chinese medicinal residue,the recyclable utilization of Chinese medicinal resi-due,and the protection of the ecological environment.
