在浙江绍兴烟区采用大田试验,研究了在等氮条件下,有机氮部分替代无机氮对香料烟产值及上部叶品质的影响。结果表明,在合适的有机氮和无机氮比例下,有利于香料烟的产量、产值及上等烟比例的提高,上部叶（A1）烟碱、总氮含量的减少,同时有利于上部烟叶总糖、还原糖、糖碱比、钾、氯、矿质元素的增加。对浙江绍兴烟区而言,有机氮和无机氮比例为50∶50时,香料烟产量、产值最高,上部烟叶的品质最好。

A field experiment was conducted in Shaoxing,Zhejiang Province,China,to study the effect of combined use of organic and inorganic nitrogen fertilizer on the yield,economic value and upper leaves quality of oriental tobacco.The results indicated that under the proper ratio of organic nitrogen and inorganic nitrogen fertilizer,the yield,economic value and fine tobacco ratio increased,nicotine and nitrogen content in tobacco upper leaves decreased,total sugar content,reducing sugar content,sugar and nicotine ratio,K content and Cl content,and mineral elements content in tobacco upper leaves increased.In conclusion,in this study,the 50∶50 ratio of organic nitrogen and inorganic nitrogen is the best for oriental tobacco application in Zhejiang Province among the treatments.
