Study On Four Pivotal Technologies Of High Quality And Special Tobacco In Shimen

The paper researched the formation and maintain of the high quality and special tobacco style in the Shimen mountain area, through the selection of the special varieties of tobacco, the cultivation methods in the field trials, the chemical analysis in the laboratory, the research on ecological regionalization, industrial verification. At the same time, analyzed the correlation and the rate of contribution of the varieties, the ecological condition and the cultivation measures in the formation the style of special tobacco in Shinmen mountain. Finally, we summarize four pivotal technologies of developing the special tobacco.We studied the different planting density had effect on quality of the special tobacco, the different transplanting dates affected the growth and quality of the clued-tobacco, and the ecological environment contributed to the rate of the formation on the flavor style of the special tobacco. The results showed that Yunyan97was superior to Xiangyan4in the agronomic character, physical properties, the coordination of chemical composition of tobacco leaf, sensory quality, yield and output value etc. What with the planting density, the room and spacing of0.5m×1.2m was the best, and the model of0.5m×1.1m secondly. Among the transplanting periods, the current conventional transplanting period was appropriate, and followed by before the time of7days.
