A field experiment was carried out in Zhengning County in Gansu Province in 2024 in order to study the effects of bio-organic fertilizer (BIO) application on chemical and aromatic qualities of Flue-cured Tobacco in East of Gansu 精品文档，word 文档精品文档---下载后可任意编辑Province and its preliminary echanisms. The results shown that:Chemical quality of flue-cured tobacco was proved with applying bio-organic fertilizer,the contents of potassium and nicotine and total soluble saccharides and reducing sugar within tobacco leaves were increased significantly,the ratio between total soluble saccharides and protein trended more to normal and measured up to the standard of high quality tobacco leaves. the content of potassium in upper leaves,middle leaves and bottom leaves were increased by 30.20%,26.30% and 50.50% respectively compared with CK and nicotine by 42.67%,28.50%,99.11% and 20.38% respectively.
