摘　　要：为明确郴州欧阳海基地单元稻作烤烟的施氮量,调查分析了3种施氮水平下的烤烟农艺性状、干物质积累和经济性状。结果表明:(1)较高的施氮量对烟株生长有一定的促进作用,烤烟生长优势较明显。(2)较高的施氮量不利于上等烟比例的提高,但由于其产量高,产值也高。(3)兼顾烟叶产量和产值及生产成本,郴州欧阳海基地单元稻作烤烟施氮量水平应控制在150 kg/hm^2为好。Investigation and analysis of agronomic trait,dry matter accumulation and economic character of flue-cured to-bacco were made under 3-types nitrogen application rate to explicit the suitable nitrogen levels in Ouyanghai base of Chenz-hou.The results showed that:(1)higher nitrogen application rate can promote tobacco growth obviously.(2)higher nitro-gen application rate goes against increasing the fine tobacco ratio,but its yield and out-put value are more than the other treatments.(3)nitrogen applied rate was 150 kg/hm2 consideration to tobacco yield,out-put value and costs in Ouyanghai base of Chenzhou.
