In order to investigate the solution to the problem of phosphorus fixation during maize cultivation in acidic soil，ammonium polyphosphate(APP)was used to formulate three special compound fertilizers for maize with different polyphosphate ratios(P1，P2，and P3 treatments). The no fertilizer(CK)，traditional fertilization(FP)，and application of corn specific compound fertilizer prepared using monoammonium phosphate (MAP) treatments were used as controls. The impacts of different fertilizer application measures on soil phosphorus，maize growth and development，and yield were investigated in field experiments. The results demonstrated that the P1-P3 treatments exhibited a 14.6% increase in yield compared to the FP treatment. Additionally，the rhizosphere soil pH demonstrated an increase of 0.37%-1.94%. Furthermore，the soil available phosphorus content of the P2 treatment at the spathe stage demonstrated a notable increase of 46.5%. In comparison to the MAP treatment，the soil available phosphorus content of the P2 treatment at the spathe stage increased by approximately 50.2%. In comparison to the P1 and P3 treatments，the P2 treatment resulted in an increase in yield by 12.3% and 6.2%，respectively. Additionally，the total phosphorus content and phosphorus accumulation in the aboveground were markedly elevated by 15.7%-42.3% and 24.5%-67.5%，respectively. In other words，the application of a compound fertilizer containing polymerized phosphorus in acidic soil could increase the rhizosphere soil pH and soil available phosphorus content，promote the absorption of phosphorus by maize，and significantly enhance the growth and developmental traits of maize，thereby increasing yield. The P2 treatment was identified as the optimal polymeric phosphorus composite fertilizer treatment in terms of phosphorus fertilizer bias productivity，maize yield components，and overall yield results. This suggested that the application of a special maize fertilizer containing polyphosphate(APP 40%)to acidic soil could result in an increase in soil available phosphorus content and a subsequent enhancement in maize yield.
