［Objective］ To investigate the effects of microbial fertilizer application under brackish water irrigation on salt ion content in saline soil and on the growth of Lycium barbarum, as well as to elucidate the relationship between soil salt ions and Lycium barbarum growth indices. ［Methods］ A series of field experiments were conducted on moderately saline soils in the Hetao Irrigation Area. Four different application rates of microbial fertilizer were tested under brackish water irrigation conditions: F1 (45 kg/hm2), F2 (75 kg/hm2), F3 (105 kg/hm2), and F0 (0 kg/hm2, as control). ［Results］ Soil salt ion levels declined with increased microbial fertilizer application. Notably, compared to F0, the F3 treatment significantly reduced Na+, K+ and Cl- levels by 49.22%, 40.20%, and 47.80%, respectively, throughout the reproductive period (p<0.05). Additionally, plant height, ground diameter, canopy width, and new branch growth rate in LBP significantly increased with higher microbial fertilizer levels (p<0.05), with t
