摘　　要：采用正交试验,系统研究了不同移栽期、不同施氮量、不同品种对烤烟干物质、农艺性状和经济性状的影响。单因子分析表明,三因素对干物质积累、农艺性状的贡献程度为移栽期>施氮量>品种,对产量的贡献程度为移栽期>品种>施氮量。各处理组合干物质积累最大、农艺性状最佳的为处理3(T1N3V3),即4月30日移栽,施用105 kg·hm-2氮的NC71,经济性状最好的为处理4(T2N1V3),即4月20日移栽,施用75 kg·hm-2的NC71品种。With orthogonal test,a field experiment was conducted to study effect of nitrogen （N） application levels,transplanting periods on plant dry matter accumulation,agronomic characters and yield and economic characters of different flue-cured tobacco cultivars.The results showed that the contribution proportion of transplanting time was more than nitrogen （N） application levels,and cultivar was the lowest for plant dry matter accumulation and agronomic characters.While the contribution proportion of nitrogen （N） application levels was the lowest and transplanting time was the highest,cultivar was the middle one for the yield.The treatment 3 which was NC71 and nitrogen （N） application level was 105 kg · hm-2,transplanted at April 30th had the best plant dry matter accumulation and agronomic characters,The treatment 4 which was NC71 and nitrogen （N） application level was 75 kg · hm-2,transplanted at April 20th had the highest yield.
