摘要
Abstract
[Objective] The research aimed to study the effects of different nitrogen form ratio (basic fertilizer and topdressing fertilizer) on yield and quality of flue-cured tobacco. [ Method] Field plot method was adopted in Baoshan tobacco growing area in Yunnan Province. According to the different proportions of the nitrogen forms (the nitrate nitrogen and ammonia nitrogen) in the basic fertilizer and the topdressing, six different treatments were designed to research the effects on agronomic characters, economic characters and quality of flue-cured tobacco. [Result] As far as agronomic trait and economic trait,the effects of the treatment T3 (basic fertilizer; nitrate nitrogen 40% + ammonium nitrogen 60% , top-dressing fertilizer; nitrate nitrogen fertilizer 60% + ammonia nitrogen 40% ) and T4 (basic fertilizer: nitrate nitrogen 60% + ammonia nitrogen 40% .topdressing fertilizer; nitrate nitrogen fertilizer 40% + ammonium nitrogen 60% ) were the best. As far as major elements and trace elements in the tobacco leaves,there weren' t significant differences. [ Conclusion] The treatment T3 and T4 were benefit to the absorption of mineral nutrition elements and the accumulation of the dry matter in flue-cured tobacco, whose intrinsic chemical components were coordinated.
