摘要
试验研究了不同时期打顶对烤烟生长发育及产质量的影响,结果表明:随着打顶时期的推迟叶片厚度逐渐减小;上、中部叶片烟碱含量逐渐降低,下部叶则先升高后降低;两糖含量先升高后降低。综合分析,以初花前后打顶为宜。
The effects of different topping dates on the growth,development,yield and quality of flue-cured tobacco were studied through field experiments in 2008.The results showed that when the topping date was delayed,the leaf thickness decreased gradually,the nicotine content in the upper and middle leaves decreased gradually,while the nicotine content in the lower leaves increased first and then decreased,the total sugar and reducing sugar content in all leaves increased first and then decreased.Comprehensively c...
