Abstract
Guiyan 4,a tobacco cultivar,was employed to investigated the effect of nitrogen(N) application amount on the dry matter and N,phosphorus(P) or potassium(K) accumulation in the present research.The results showed that within the application range of 0~8.5kg·667m2,the dry matter,as well as N,P,or K accumulation of tobacco plants for all stages were obviously increased along with the increase in N application.When the range was 4~8.5kg·667m2,however,no synchronous increase in accumulation of these parameters were obtained.The results indicated that to certain extent,the increase in N application may have a positive effect on the growth of tobacco,as well as its P,and K accumulation.
