摘　　要：为实现赤霉素发酵滤渣的高值化利用,本研究全面评估了猪粪与赤霉素发酵滤渣在不同配比、接种量和pH值条件下对丝光绿蝇幼虫转化效率的影响。结果表明,调节初始赤霉素发酵滤渣的pH值至6.0,将猪粪与赤霉素发酵滤渣按照80%∶20%(质量分数,下同)、60%∶40%、40%∶60%的比例混合能显著提升幼虫的转化率分别至14.29%、13.34%和11.57%。将猪粪与赤霉素发酵滤渣按3∶2的质量比混合,接种量为3.0%~7.5%时,幼虫转化率为10.48%~15.02%,综合蝇蛆产量和成本,以3.0%的接种量较为合适。当猪粪与赤霉素发酵滤渣以3∶2的质量比混合时,混合物料的pH值以6.5~7.5为佳。综上,通过调控猪粪与赤霉素发酵滤渣的配比、接种量和pH值,可以提高蝇蛆的转化效率,提升赤霉素发酵滤渣处理的附加值。To realize the high-value utilization of gibberellin fermentation residue resources,the effects on the bioconversion efficiency of pig manure and gibberellin fermentation residue under different ratios,inoculum amounts and pH values with fly maggots(Lucilia sericata)larvae were comprehensively evaluated in this study.The results showed that after adjusting the pH of the initial gibberellin fermentation residue,when pig manure and gibberellin fermentation residue was mixed at the ratio of 80%∶20%(mass fraction,the same as below),60%∶40%,40%∶60%,the bioconversion rate was 14.29%,13.34%and 11.57%,respectively.When pig manure and gibberellin fermentation residue was mixed at the ratio of 3∶2,the bioconversion rates of the treatment groups with inoculation amount ranging from 3.0%to 7.5%were 10.48%-15.02%.Given the cost and the yield of fly maggots,the inoculum amount of 3.0%was appropriate.When pig manure and gibberellin fermentation residue was mixed at the ratio of 3∶2,the pH of the mixture should be 6.5-7.5.In general,the bioconversion efficiency of pig manure and gibberellin fermentation residue with fly maggots could be improved by regulating the mix ratios of pig manure and gibberellin fermentation residue,inoculum amount and pH value,to increase the additional value of gibberellin fermentation residue.
