Abstract


Tobacco production quality suitable production , quality of tobacco affected by many other factors such as climate , soil , varieties , fertilization and baking technology . Which fertilization is decided tobacco production , the output value of the first factor . At the same time , in this system , fertilization is the biggest variables fertilization will first affect the soil environment , thereby affecting the quality of tobacco , there is the necessary link between the three . Moreover , soil fertilization always decide the sustainability of tobacco production , the stable development of the important factors , therefore , in a certain environment and a variety of conditions , fertilization is one of the key technologies of flue-cured tobacco quality and yield . The quality of China 's tobacco , compared with the United States and Zimbabwe 's tobacco , there is a big gap , one of the major limiting factor is unbalanced smoke soil nutrient status . Variable rate fertilization based on GIS technology is the key to solve this problem , the ecological environment of the tobacco-growing areas of GIS-based analysis , tobacco fertilization modeling , tobacco fertilization expert system development . The completed work includes: 1 . Climate , landforms and soil analysis of the basis of ecological conditions Jiaxian tobacco production , and evaluation of the suitability of the the Jiaxian ecological conditions of tobacco production . Study GIS spatial data acquisition , storage , management , analysis and processing functions , and the establishment of the the typical smoke District of Jiaxian ecological environment database . 3 with reference to previous studies , the establishment of the tobacco fertilization model above in Mapobject platforms , the integrated coupling of the tobacco-growing areas of the ecological environment, library and tobacco fertilization model library , establish tobacco fertilization expert system to achieve tobacco variable based on the location variable \. Through field investigation to fertilization system validation , the results show that the system can better guidance Jiaxian tobacco fertilization .
