为探究磷肥有机替代、秸秆还田对棉花养分吸收、磷肥利用效率及棉花产量的影响，本研究基于国家灰漠土肥力与肥料效益监测站5年田间微区棉花连作定位试验，以7种施肥措施为样本，于2022年棉花成熟期开展棉田土壤田间调查研究。结果表明，磷肥有机替代和秸秆还田均能提升棉株氮磷钾养分吸收，各器官氮素平均含量在1.75~40.90 g·kg-1之间，磷素平均含量在1.46~11.28 g·kg-1之间，钾素平均含量在3.11~25.03 g·kg-1之间。综合肥料投入和养分吸收，50%的磷肥有机替代和秸秆还田最能增强棉株吸氮能力和促进干物质积累，50%的磷肥有机替代对棉株吸磷能力最强且最有利于实现棉花节肥增钾的效果。棉株各器官N:P变化范围为1.20~12.01，磷肥有机替代和秸秆还田使茎、叶、蕾/铃/壳的N...
