| Abstract: | Objective]One of the key techniques to cultivate flue-cured tobacco is fertilizer applica- tion,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 flue-cured 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. |
