不同种类叶面肥对烤烟农艺性状及抗病性的影响

[目的]研究不同种类叶面肥对烤烟农艺性状及抗病性的影响。[方法]以烤烟品种云烟97为研究材料,通过田间试验研究不同种类叶面肥对烤烟农艺性状、花叶病抗性、赤星病抗性、气候斑病抗性、黑胫病抗性的影响。[结果]施用维果7号处理的烟叶农艺性状表现在各处理中相对较好,施用铜大师+大师兄处理的烟叶花叶病、赤星病、气候斑病、黑胫病等病害发病率及病情指数较低,综合防效相对较好。[结论]该研究为武隆烟区筛选出一种抗病性较好的叶面肥,为改善烟叶品质、提高烟农收入提供了理论基础。

Effects of Different Kinds of Foliar Fertilizers on Agronomic Characters and Disease Resistance of Flue-cured Tobacco

[Objective] To research the effects of different kinds of foliar fertilizers on the agronomic characters and disease resistance of flue-cured tobacco.[ Method] With flue-cured tobacco variety Yunyan 97 as the research material, field experiment was carried out to research the effects of different kinds of foliar fertilizers on the agronomic characters of flue-cured tobacco, and its resistances to mosaic disease, brown spot, black shank and weather fleck.[ Result] Tobacco leaves in treatment of applying Viggo 7 had relatively good agronomic characters;treatment of applying copper master +big brother showed relatively low incidence rate and disease index of mosaic disease, brown spot, black shank and weather fleck, and realtively good integrated control effects.[ Conclusion] This research selects relatively good foliar fertilizer in Wulong Tobacco Area, and provides theoretical basis for improving tobacco leaf quality and enhancing the income of tobacco farmers.
