Abstract

Rapeseed is highly sensitive to boron (B) and nitrogen (N) deficiency, yet their interaction effects on rapeseed remain poorly understood. Here, a factorial pot experiment revealed that under N-sufficient conditions, B deficiency severely impaired reproductive growth, photosynthesis, and yield formation, while also reshaping rhizosphere bacterial communities. However, moderate N limitation alleviated these negative effects. Massilia and Sphingomonas were identified as core microbiota responsive to B availability under N-sufficient conditions, correlating positively with B uptake and photosynthetic N use efficiency (PNUE). Shifts in microbial composition were linked to soil pH and available B, whereas reduced PNUE under B deficiency resulted from disrupted N allocation within the photosynthetic apparatus. Balanced N and B supply improved nutrient uptake, microbial stability, and seed yield, underscoring the importance of integrated nutrient management in sustainable rapeseed production.

氮硼在油菜营养吸收、光合作用和根际生态中的相互作用。

油菜对缺硼、缺氮非常敏感，但对缺硼、缺氮对油菜的互作效应尚不清楚。本研究发现，在n充足条件下，B缺乏严重损害了植物的生殖生长、光合作用和产量形成，同时也重塑了根际细菌群落。适度限氮可以缓解这些负面影响。在N充足条件下，麻孢菌和鞘单胞菌是响应B有效度的核心菌群，与B吸收和光合N利用效率（PNUE）呈正相关。微生物组成的变化与土壤pH值和有效氮有关，而氮素缺乏导致光合机构内氮分配中断导致氮素利用效率降低。平衡的氮和硼供应改善了养分吸收、微生物稳定性和种子产量，强调了综合养分管理对油菜籽可持续生产的重要性。
