| 摘 要： | 通过试验，研究不同施氮量对烤烟产量、质量和经济效益的影响。结果表明：随着氮水平的提高，株高、叶片数、最大叶面积有增加趋势；气候斑、普通花叶病和马铃薯Y病毒发病率也有升高趋势；烤后烟单叶重增加，产量增加，烟叶质量呈现先升高后下降的趋势。综合各因素，以处理D（比正常施氮量少施20％纯氮）表现最好，有利增产和提高质量。 |

| Abstract: | The effects of different amount of nitrogen application on yield,quality and economic benefit of flue-cured tobacco were studied.The results showed that along with the increase of application rate of nitrogen fertilizer,the plant height,number of leaves and maximum leaf area were all increased,the incidence rate of climate spot disease,mosaic disease and potato virus Y revealed rising trends,the weight of roasted single tobacco leaf and the output per unit area were enhanced,and the quality of tobacco leaves increased firstly and then declined.Comprehensively considering the above points,treatment D(20% less than the normal application rate of pure nitrogen) had the best effects. |
