不同栽培措施对烤烟生长·产值和烟碱含量的影响

[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/hm^2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/hm^2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。

Research on Flue-cured Tobacco Growth,Yield and Nicotine Content with Different Cultivation Measures

[Objective] The research aimed to study the cultivation measures of tobacco in Xingshan to suit for the growth and reduce the nicotine content effectively. [Method] Four designed cultivation methods were compared with conventional cultivation technology. [Result] The flue-cured tobacco grew more rapidly in early stage, upper leaves grew more better in budding period by low ridge film and N 97.5 kg/hm2. The economic characters were equal to the tobacco cultivated by ridging. And the nicotine content of upper leaves was in comfort zone with better quality. [Conclusion] Unit economic profit of tobacco by low ridge film and N 97.5 kg/hm2 was equal to conventional cultivation, which had evident effect to reduce.
