Abstract: 本研究初步构建了一套丛枝菌根(Arbuscular Mycorrhizal, AM)真菌参与的鱼菜共生复合体系，通过根系拦截与菌丝介导的营养交换机制，从而实现花生(Arachis hypogaea L.)生长、罗非鱼(Oreochromis niloticus)、中华圆田螺(Cipangopaludina cathayensis)养殖与水质净化的协同优化。室内外联合试验显示，相比未接菌异形根孢囊霉(Rhizophagus irregularis)、拦截根系的对照组(NM)，接种的AM组(接种 + 拦截根系)花生生长指标、根系侵染率光合作用均处于较高水平；且AM组的循环水体中总氮(TN)、总磷(TP)和化学需氧量(COD)的回落速率更快。同时，AM组鱼类的生物量优于对照组(NM)。综上，AM真菌可通过强化养分转化与转运、优化水体环境，协同提升作物生长与水产养殖效果，为生态循环农业提供技术支撑。In this study, a composite aquaponic system involving arbuscular mycorrhizal (AM) fungi was constructed. Through the nutrient exchange mechanism mediated by root interception and hyphae, the synergistic optimization of Arachis hypogaea L. growth, Oreochromis niloticus and Cipangopaludina cathayensis culture, and water purification was achieved. Indoor and outdoor combined experiments showed that compared with the non-inoculated control group (NM, root interception without Rhizophagus irregularis), the AM group (inoculation + root interception) exhibited higher values in peanut growth indices, root colonization rate, and photosynthesis. In addition, the concentrations of total nitrogen (TN), total phosphorus (TP), and chemical oxygen demand (COD) in the circulating water of the AM group decreased more rapidly. Meanwhile, the fish biomass in the AM group was superior to that in the control group (NM). In summary, AM fungi can synergistically improve crop growth and aquaculture performance by enhancing nutrient transformation and transport and optimizing the water environment, providing technical support for ecological circular agriculture.
