To acquire resources for promoting plant growth and enhancing plant tolerance to salt stress，the salt-tolerant strains which could produce 1-aminocyclopmpane-1-carboxylate(ACC)-deaminase from the rhizosphere of Artemisia halodendron were screened and identified by molecular biological methods. The growth-promoting effect was confirmed through germination tests and pot experiments. Two salt-tolerant strains producing ACC-deaminase were screened. Strains AhR1 and AhR5，identified as belonging to Pseudomonas，exhibited ACC-deaminase activity of 15.72 and 48.38 μmol/(mg·h)，respectively. Additionally，both strains were found to produce biofilm，indoleacetic acid，and decompose inorganic phosphorus. The results indicated that at salt concentrations of 2‰-6‰，the low concentration (OD600=0.1) of the two strains significantly promoted the growth of rapeseed roots and buds. The results of the pot experiment on rapeseed indicated that strain AhR1 increased the dry weight of rapeseed by 22.07% at 4‰ salt content，while strain AhR5 increased it by 29.91% at 2‰ salt content. These findings suggested that strains AhR1 and AhR5 significantly promoted the growth of rapeseed under salt stress，and provided valuable resources for the development of microbial fertilizers and soil improvement in saline-alkali land.
