China is the largest producer and consumer of tobacco ( L.) in the world, and the cultivation and production of tobacco have extremely high economic value and social influence. Applying organic-inorganic fertilizer is a key strategy for boosting tobacco yield and quality. This meta-analysis examines 632 observations from 169 articles to determine the precise influence of organic-inorganic fertilizer on tobacco. It evaluates the effects of different tobacco types and fertilizer compositions on yield and quality after fertilizer application. The application of organic-inorganic fertilizer significantly increased the yield (3.4%), but it mainly improved the balance of chemical composition and enhance the quality of tobacco (high-grade tobacco, 10.3%; reducing sugar content, 5.5%; nicotine content, -5.6%). The Y85 and Y87 varieties showed the most positive response to fertilization, with yield increases of 5.59% and 5.82%, respectively, and high-grade tobacco leaf rates increased by 14.92% and 11.04%, respectively. Fertilizers with a low organic nitrogen ratio (15%-30%) are more effective for increasing yield, while those with a medium to high ratio (50%-60%) improve tobacco's chemical quality. The application of organic-inorganic fertilizer balanced the nutrient distribution within the tobacco plants, leading to simultaneous increases in both yield and quality. This study quantitatively assessed the effects of organic-inorganic fertilizer on the yield and quality of tobacco and provides a solid theoretical foundation for the scientific and high-quality application of organic-inorganic fertilizer in various tobacco cultivation areas.
中国是世界上最大的烟草生产国和消费国，烟草种植与生产具有极高的经济价值和社会影响力。施用有机无机肥是提高烟草产量和品质的关键策略。本荟萃分析考察了169篇文章中的632项观测结果，以确定有机无机肥对烟草的确切影响。它评估了不同烟草类型和肥料成分对施肥后产量和品质的影响。施用有机无机肥显著提高了产量（3.4%），但主要改善了化学成分的平衡并提升了烟草品质（上等烟，10.3%；还原糖含量，5.5%；尼古丁含量，-5.6%）。Y85和Y87品种对施肥反应最为积极，产量分别提高了5.59%和5.82%，上等烟叶率分别提高了14.92%和11.04%。有机氮比例低（15%-30%）的肥料对提高产量更有效，而中等至高比例（50%-60%）的肥料则能改善烟草的化学品质。施用有机无机肥平衡了烟草植株内的养分分布，从而实现了产量和品质的同步提高。本研究定量评估了有机无机肥对烟草产量和品质的影响，为有机无机肥在各烟草种植区的科学、高质量施用提供了坚实的理论基础。
