不同栽培措施对烤烟根系生长发育及产质量的影响

Effect of Different Cultivation Measures on Root Growth Development,Yield and Quality of Flue-cured Tobacco

通过对烤烟根系与烟叶产质量关系研究,表明烤烟根系发育与烟叶生长、主要经济性状、烟叶化学成分的关系是:随着根系重量的增加,烟叶生长加快,同时烟叶化学成分趋于协调。研究结果还发现,深栽、适时揭膜培土可有效改善根系生长发育环境,促进根系发育,并使烟株在生长过程中营养均衡协调,从而提高烟叶产量和质量。

Relation between root of flue-cured tobacco and tobacco yield ＆ quality was studied. It was found that growth of tobacco speeded up and tobacco chemical composition tended to coordinate with increase of root weight. The study indicated that deep planting, timing uncovering plastic and ridging could improve the environment of root growth effectively, promote root development, and balance the nutrition distribution during the growth of tobacco plant, so as to enhance tobacco production and quality,
