延边烤烟水肥交互作用对烟叶产质量的影响

Effect of interaction between water and fertilizer on quality to tobacco leaf in Yanbian area

以延边主推品种吉烟九号为材料,进行不同灌溉条件和肥料施用量处理.通过调查农艺性状,田间自然发病率,经济性状,主要化学成分等,对水肥条件的互作关系进行研究.结果表明,遇旱灌水效果显著,经济效益明显提高,化学成分方面没有明显差异.因此,相同的肥料条件,遇旱灌水效果显著,相同的水分条件,施纯氮量60 kg/hm2为宜;水肥互作不显著.

Designed different water and fertilizer treatment by the material of Jiyang. Researched the relation of water and fertilizer by detected agronomic, pathologic, economic traits, chemical component. The resuits showed that irrigate effect is very prominent and had better economic character. The chemical components and physical characters had no difference.
