Many external and internal studies in based on the relevant literature and consult to tobacco experts,based on the experimental research of the years between 2004 and 2005,the basic model of soil-N of distribution was developed after analysising the content of nitrogen in the whole plant of *** model is designed to simulate dynamically absorption and distribution of nitrogen for *** diversification of nitrogen in tobacco is exhibited dynamically in the form of curve which originates from the software of Visual Basic *** result showed that the simulated value of nitrogen content is not remarkably different from the measured value in root,stem and leaf of tobacco in the level of 0.05,and the simulation value of nitrogen content fit the measured value very well in the *** proveds a concerning modulus of0.9934 that the 1:1 graphical comparison between simulation value and measured data of nitrogen content in tobacco *** simulated and the measured agreed *** model helps to forecast and conduct the management of nitrogen fertilizer in tobacco field.
