Results showed that flue-cured tobacco took up more N from soil than from N fertilizer, and 18.67%-29.32% of N absorbed by flue-cured tobacco was derived from N fertilizer, 70.68%-81.33% from soil under two level fertility fields.

结果表明，在高低土壤肥力条件下，烤烟吸收的土壤氮量多于吸收的肥料氮量，烤烟吸收的氮素18.67%~29.32%来自于肥料，70.68%~81.33%来自于土壤。

Although effects of nitrogen fertilizer on nitrogen accumulation and nitrate reductase in tobacco leaf had been extensively studied, impacts of nitrogen fertilizer on flue-cured tobacco leaf nitrogen metabolism in dry land and paddy field were not well documented.

试验采用裂区设计，以硝态氮和铵态氮两种氮素形态为主处理、5个供氮水平为副处理，在大田条件下研究了水田与旱地烤烟在团棵、旺长、脚叶采烤、腰叶采烤和顶叶采烤等5个生育期烟叶的总氮浓度、硝酸还原酶和谷酰胺合成酶活性的氮肥效应。

The results showed that as compared with the equal chemical fertilizer (T2), tobacco special fertilizer could improve the physical character of soil and ensure growth steadily to form perfect plant figure.

结果表明：与等氮磷钾养分对照(T2)比较，烟草专用肥处理(T4)可以改善土壤的物理性状；有利于烟株稳健生长，形成理想的株型；降低烟叶的蛋白质含量、减小两糖差值，糖碱比和氮碱比更加适宜，改善烟叶品质；但是烟叶产量、中上等烟叶产量与等氮磷钾养分对照相似。

In the tobacco production, the measure of only using fertilizers in soil can notimprove the quality of tobacco because soil nutrients releasing is not coincident withthe nutrients absorb rules of tobacco, and the leaf fertilizer with low cost and higheffect can harmonize the nutrients of tobacco leaf and improve the economic benefitof tobacco under assorting with soil fertilizer.

烤烟生产中，由于土壤养分释放状况与烤烟吸肥规律并不一致，单一的土壤施肥并不能达到改善烟叶品质的目的，而成本低、肥效快的叶面肥可以针对烤烟不同生长发育期各异的养分需求特点，配合土壤施肥，协调烟叶自身营养状况，改善烟叶内在品质，进而提高烤烟经济效益。
