摘　　要：为探讨不同有机氮用量对烤烟(云烟85)产量和品质的影响,采用田间试验与室内分析相结合的方法,在NPK总养分用量相同的条件下进行试验。结果表明:(1)配施有机肥可以增加烤烟烟株的株高、叶长、叶宽和叶面积、有效叶数,能有效促进烤烟的生长发育;(2)配施有机肥可以增加烤烟的含糖量,降低上中部叶的氮含量,改善烟叶质量,使烟叶的内在各化学成分更趋于协调,更符合优质烟的要求;(3)配施有机肥能够提高上中等烟叶比例,提高烤烟的产量和产值,产量增加了4%～13%,产值增加了1 153.04～5 101.76元/hm2;(4)在不同有机氮用量的3个处理中,以20%有机氮处理的效果较好。In order to study the effects of different organic nitrogen rates on yield and quality of flue-cured tobacco, field experiment combined with laboratory analysis was employed in this study, tests was carried out under the same conditions NPK total nutrient dosage. The results showed that： （1） Organic fertilizer could increase the flue-cured tobacco plant height, leaf length, leaf width and leaf area, the effective number of leaves, could effectively promote the growth and development of flue-cured tobacco. （2） Organic fertilizer could increase the sugar content of the flue-cured tobacco, reduce the upper and the middle leaf nitrogen content, improve the quality of tobacco, organic fertilizer could make its chemical composition tend to be more coordination, more consistent the requirements of high quality tobacco. （3） Organic fertilizer could improve the ratio of upper-tobacco leaves and middle-tobacco leaves, improve tobacco yield and value, the yield was increased by 4%～13%, the value was increased 1 153.04～5 101.76 yuardhm2. （4） In the three treatment, the 20% treatment was the best in all treatments.
