Abstract:

Northeast quality flue-cured tobacco production and decision-making system development and application, it is to develop a system, then to product statistical data modeling embedded systems of using related factors of tobacco yield, and developed a graphical interface, as long as farmers or tobacco companies make the input and yield data related to factors, finally calculated by the model can be immediately cured tobacco production data., so this paper applied the theory of stepwise regression, and made use of the toolbox of mathematical statistics of MATLAB software, selected the related factors with tobacco yield, such as transplanting time, average temperature from May to August and fertilization, then established stepwise regression equation with tobacco yield of Heilongjiang Province and these factors. Found out the factors that have a significant effect to tobacco production. The results showed that there was a significant effect to tobacco yield that average temperature from May to August, transplanting time, the number of pure phosphorus fertilizer per acre applied, the number of pure K fertilizer per acre applied, the number of pure P cake fertilizer per acre applied. According to the conclusions, to suggest technical person to pay attention to the influence of transplanting time to tobacco yield, and further regulate the number of fertilizer usage in the production.
