Dynamic Modeling on Nitrogen Assignment in Tobacco

Abstract : 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 tobacco. The model is designed to simulate dynamically absorption and distribution of nitrogen for tobacco.The diversification of nitrogen in tobacco is exhibited dynamically in the form of curve which originates from the software of Visual Basic 6.0. The 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 model. It proveds a concerning modulus of 0.9934 that the 1:1 graphical comparison between simulation value and measured data of nitrogen content in tobacco leaf. The simulated and the measured agreed perfectfull. The model helps to forecast and conduct the management of nitrogen fertilizer in tobacco field.
