[目的]研究适宜兴山烟叶产区烤烟生产并能有效降低烟碱含量的栽培措施。[方法]设计4种栽培方式与常规栽培对照进行小区试验。[结果]实施低垄覆膜+N97.5kg/hm2栽培处理烤烟前期生长较快,现蕾期上部叶开片较好,经济性状与起垄覆膜处理烟叶相当;上部烟叶的烟碱含量处于较适宜范围,评吸质量较好。[结论]低垄覆膜+N97.5kg/hm2栽培处理单位经济效益与常规相当,降碱效果明显,可进行一定面积的示范。
[Objective] The research aimed to study cultivation measures suitable for flue-cured tobacco production in Xingshan tobacco producing area and effectively reduce nicotine content. [Method] Four kinds of cultivation methods were designed to compare with conventional cultivation. [Result] Flue-cured tobacco with low ridge-covering film + N97.5kg / hm2 had a fast growth in early stage, the opening of the upper leaves was better at budding stage, and the economic characters were similar to those of ridge-mulching and filming treatments. The nicotine content of the upper leaves was at More appropriate range, smoking quality is better. [Conclusion] The economic benefits of low ridge film + N97.5kg / hm2 cultivation and treatment unit were quite similar to conventional ones, and the effect of reducing alkali was obvious and a certain area could be demonstrated.
