摘　　要：【目的】施肥是烤烟栽培的关键技术之一,追肥量、追肥方法、追肥次数对烤烟的生长、发育、产量和品质都具有显著的影响;【方法】以K326为材料,研究了不同追肥次数对烤烟生长发育的影响;【结果】由本试验可知,分5次追肥的E处理的烟株生长发育状况优于其他处理和对照,说明E处理的追肥方法更有利于烟株的生长发育;【结论】五次分追的追肥方法效果最佳,此方法可用于农业生产。[Objective]One of the key techniques to cultivate flue-cured tobacco is fertilizer application, including fertilizer rate,method of top dressing and the top dressing frequence,which affect the growth,development,yield and quality of flue-cured tobacco. [Methods]this text takes the trial material with fluecured tobacco K326,and the test is conducted to study the influence of nitrogen top dressing frequence on growth and development of flue-cured tobacco. [Results]The results showed showed that the method of five times of fertilizer application is better than other treatment and compa- rison,and it help to growth and development of tobacco plants. [Conclusion]the best modes of fertilizer application is five times,and it can be used for agricultural production.
