摘　　要：畜禽粪便和厨余垃圾同步处理是解决黑水虻转化畜禽粪便效率低的有效路径,然而在畜禽粪便和厨余垃圾同步处理下黑水虻幼虫的生长规律及其成因尚不清楚.该文构建黑水虻幼虫同步处理鸭粪和厨余垃圾体系,从幼虫体质量、体长及营养成分等方面评价其生长规律,基于微生物群落及功能揭示其形成机制.研究结果表明:添加75%厨余垃圾组的黑水虻幼虫体质量、体长、粗蛋白、粗脂肪等显著高于除单一厨余垃圾组外的其他组别的相应量(P<0.05),矿物元素以及氨基酸含量等显著高于单一厨余垃圾组的相应量(P<0.05).肠道微生物研究结果表明:不同处理组之间差异主要体现在普罗威登斯菌属、漫游菌属和肠球菌属上,在75%厨余垃圾组中黑水虻微生物群落结构最稳定.方差分解分析(variance partitioning analysis,VPA)结果揭示在不同组别中幼虫生长规律主要受肠道微生物碳、氮代谢功能的影响.Livestock and poultry manure and kitchen waste co-treatment is an effective pathway to address the low efficiency of black soldier fly larvae(BSFL)in converting manure.However,the growth patterns of BSFL and their mechanisms under simultaneous treatment of livestock and poultry manure and kitchen waste are not yet clear.Therefore,the system for simultaneously treating duck manure and kitchen waste with BSFL is developed,evaluating growth patterns based on larval weight,length,and nutritional composition,and revealing the underlying mechanisms through microbial community and function.The results show that in the S75 group,BSFL exhibits significantly hig-her weight,length,crude protein,and crude fat compared to other groups,excluding the S100 group(P<0.05),and has higher mineral and amino acid content compared to the S100 group(P<0.05).Intestinal microbiota results indicate that differences among treatment groups are mainly in Providencia,Vagococcus,and Enterococcus genera,with the microbiota structure in the S75 group being the most stable.VPA results reveal that the growth patterns of larvae in the different group are mainly influenced by the carbon and nitrogen metabolism functions of intestinal microbiota.
