摘要： Enhancing sustainable rice production is crucial for global food security. Here we demonstrate that 0.1 mg kg(-1) selenium-engineered nanomaterials promote rice (Oryza sativa L.) tillering and yield by optimizing the rhizosphere microbial community, improving nitrogen use efficiency, and modulating plant hormones and growth-related genes. Using pot experiments with five different soils and field trials in China, we found that soil organic carbon strongly influences nanomaterial effectiveness. Field results demonstrated a 10.7% yield increase and a 309.8% rise in grain selenium concentration, with no adverse effects on soil quality. Predictive modeling calculated that selenium-enhanced agriculture could increase profits by +$231.5 ha(-1), reduce CO2 emissions by 1.12 Tons ha(-1), and produce selenium-rich grains (similar to 20 mu g.100 g(-1)) to address dietary deficiencies. Our findings highlight the potential of selenium nanomaterials to sustainably boost rice production, urging further research across diverse ecosystems to optimize their agricultural and environmental benefits.
