摘要
对烤烟进行的氮肥运筹方式研究表明，氮肥用量对烤烟产量和上等烟比例有明显影响，其最佳施用量为９０ｋｇ／ｈｍ２；施肥方法则影响不显著，根据本地春旱、夏涝的气候特点，正确的施肥方法应该是重施基肥，及时追肥；品种宜采用“ＮＣ８９”
The study on nitrogen operation of tobacco showed that diferent cultivars had their own ecological adaptability .Yield and high quality leaf proportion were different markedly between different cultivars. The field test recommended “NC89”, Nitrogen level influenced yield and high quality leaf proportion notably.The best nitrogen fertilizer application level was 90kg/hm 2, but the method of fertilization did not affect them markedly . Based on local weather of spring drought and summer waterlogging,the proper method of fertilization should focus on sufficient basal fertilizer and timely top dressing.
