The effects of several commonly used biostimulants on promoting nutrient uptake in maize were investigated，providing a basis for maize fertilization and fertilizer synergists. A pot experiment was conducted to investigate the effects of different biostimulants on maize growth，and a comprehensive evaluation was performed based on 18 maize growth indicators.A total of 16 treatments with different types and concentrations of biostimulants were set up in the experiment，including the control group(CK)，mineral-derived humic acid at 0.5%(M-HAL)，mineral-derived humic acid at 1%(M-HAM)，mineral-derived humic acid at 1.5%(M-HAH)，biochemically-derived humic acid at 0.5%(B-HAL)，biochemicallyderived humic acid at 1%(B-HAM)，biochemically-derived humic acid at 1.5%(B-HAH)，earthworm enzyme at 0.1%(EEL)，earthworm enzyme at 0.2%(EEM)，earthworm enzyme at 0.3%(EEH)，citric acid at 3%(CAL)，citric acid at 6%(CAM)，citric acid at 9%(CAH)，polyglutamic acid at 1%(PAL)，polyglutamic acid at 2%(PAM)，and polyglutamic acid at 3%(PAH). Each treatment was arranged in a randomized complete block design with 5 replicates. No significant differences were observed among the biostimulant treatments in terms of soil pH，EC，organic matter，alkaline hydrolysable nitrogen，available phosphorus，or available potassium. However，compared with CK，the biostimulant treatments significantly reduced the content of soil available phosphorus and available potassium，indicating enhanced nutrient uptake by maize. EEL and PAL tveatments notably promoted root growth，significantly increasing total root length，root surface area，average root diameter，and root volume by 52.75%，57.41%，29.41%，55.39% and 42.56%，48.14%，21.57%，55.10%，respectively. Biostimulant application also improved the accumulation of nitrogen，phosphorus，and potassium per plant. Moreover，significant enhancements in plant growth parameters were observed，including plant height，stem diameter，leaf area，and dry biomass of both shoots and roots，particularly under the EEL，PAL，and B-HAL treatments. The application of bio-stimulants enhanced the absorption of soil nutrients by maize，thereby promoting the growth of both the maize roots and the above-ground parts of the plant. Among the five bio-stimulants tested，the treatments containing 0.1% earthworm enzyme，1% polyglutamic acid，and 0.5% bio-based humic acid had a more significant positive effect on the growth of maize.
