[目的]提高烟叶的产量和品质。[方法]以吉烟九号为供试材料,施用不同组合比例的硫酸锌和硫酸铁进行田间试验,比较各处理的农艺性状,田间自然发病率,经济性状和化学成分。[结果]铁锌配合施用能够提高烟叶的产量和品质。其中,处理2(FeSO_4 15kg/hm~2+ZnSO_4 10kg/hm~2)和处理5(FeSO_4 15kg/hm~2+ZnSO_4 15kg/hm~2)效果最好。[结论]该研究为提高烟叶产质量提供了理论依据。
[Objective] To improve the yield and quality of tobacco. [Method] Taking Jianyan 9 as test material, different proportions of zinc sulfate and ferric sulfate were applied to conduct field experiment. The agronomic traits, natural incidence in the field, economic characters and chemical compositions were compared. [Result] The combination of iron and zinc could improve the yield and quality of tobacco. Among them, treatment 2 (FeSO 4 15kg / hm 2 + ZnSO 4 10kg / hm 2) and treatment 5 (FeSO 4 15kg / hm 2 + ZnSO 4 15kg / hm 2) had the best effect. [Conclusion] The study provided the theoretical basis for improving tobacco yield and quality.
