不同类型钾肥对烤烟生长发育及烟叶钾含量的影响

摘要

[目的]研究提高朝阳烟区烟叶钾含量的有效措施,探索一条能够指导烟叶生产的集成技术.[方法]以云烟87为材料,研究烟田增施有机钾肥和生物钾肥对烤烟生产发育和烟叶钾含量的影响.[结果]烟田增施硅酸盐菌粉和螯合态高效钾肥均能促进烟株生长,提升烟叶外观品质,显著提高烟叶钾含量.[结论]该研究为优质烟叶的生产提供理论依据.%[Objective] To study the effective measures to improve the potassium content of tobacco leaf in Chaoyang tobacco area, and to ex-plore an integrated technology that could guide the production of tobacco leaf.[Method] With Yunyan 87 as material,the effect of chelate effi-cient potassium fertilizer and silicate powder on the growth and potassium content of the flue-cured tobacco were studied. [Result] It could pro-mote the growth of tobacco plants,enhance the appearance quality of tobacco leaves,significantly increase the potassium content of tobacco leaf by adding silicate powder and chelating state.[Conclusion] The study provides a theoretical basis for the production of high-quality tobacco.
