【目的】研究沼液配肥对大葱养分吸收利用、土壤理化性质与微生物及其作用关系的影响，为沼液配肥利用、推进沼液高效利用提供技术理论依据。【方法】于2022年5—10月，以章丘铁杆大葱为研究对象，以不追肥（NF）为对照，研究追施等氮量的化肥（CF）、沼液（BS）、沼液肥1（BSF1）和沼液肥2（BSF2）对大葱产量、养分吸收利用、土壤理化性质和土壤细菌群落结构特征的影响。【结果】与NF处理相比，CF、BS、BSF1、BSF2处理大葱产量分别提高了37.48%、63.33%、92.53%、59.78%。与CF处理相比，BS、BSF1、BSF2处理显著提高了大葱的肥料利用率（FUE，提高50.63%~71...
