flue-cured tobacco growth

The paper studied of two spurting leaf-fertilizer (FFF1 and FFF2) on flue-cured tobacco growth and the tobacco qualities.

研究了自制的新型烟草多功能叶面肥“烟博1号”（FFF1）和“烟博2号”（FFF2）喷施对烟草生长及品质影响。

In the late stage of flue-cured tobacco growth, under the same level of leaf number, leaf NR activity and root activity increased and then decreased with the increase of nitrogen application.

烤烟生长发育后期，同一留叶数条件下，叶片NR活性、根系活力随着施氮量的增加呈先升高后降低的趋势；

The research indicated that application of oil-cake fermented could promote the growth of flue-cured tobacco plant, enhance leaf yield, improve leaf quality.

实验表明，施用发酵性饼肥，可促进烟株生长发育，提高烟叶产量，改善烟叶质量和增加上等烟比例。
