[Objective] To identify highly efficient phosphate fertilizer varieties suitable for winter wheat cultivation in northern Henan Province and to provide a scientific basis for precise fertilization and soil ecological management in this region.[Methods] A field experiment was conducted with five treatments:no phosphate fertilizer(CK),triple superphosphate(TSP),monoammonium phosphate(MAP),diammonium phosphate(DAP),and ammonium polyphosphate(APP).Crop yield,phosphorus accumulation,phosphorus fertilizer utilization efficiency,soil available phosphorus content,and inorganic phosphorus fractions were examined to assess the effects of different phosphate fertilizer varieties.High-throughput sequencing technology was further employed to analyze the characteristics of gcd-harboring bacterial communities.[Results] Compared with CK,all four phosphate fertilizer treatments significantly increased winter wheat yield,phosphorus accumulation,phosphorus fertilizer utilization efficiency,soil available phosphorus content, and Ca2-P content,with the APP treatment showing the best performance.Grain yield was significantly and positively correlated with soil available phosphorus and Ca2-P contents.Although different phosphate fertilizers did not significantly alter the diversity of gcd-harboring bacterial communities,they substantially changed the community structure,with Pseudomonas identified as the dominant genus.[Conclusion] APP exhibited the best overall performance in winter wheat production in northern Henan Province and holds strong application potential,making it a recommended phosphate fertilizer variety for the region.
