Optimization of Composting Process Parameters of Sophora flavescens Residue
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.
