达州烟区生态因素与白肋烟质量特点分析

通过分析四川省达州市烟区适宜烟草种植的基本条件、气候因素、土壤养分状况及所产白肋烟叶的质量特点,结果表明:(1)该烟区具有热量资源丰富、温度较高、降雨量和空气湿度大等突出气候特点,地貌类型丘陵、低山、中低山等为主,土壤类型有紫色土、红壤、红黄壤、冲积土、水稻土等。分析表明达州烟区多项指标达到了适宜烟草生长发育的生态条件,是烟草种植适宜区。(2)达州烟区土壤养分含量存在较大差异,一般土壤多为弱酸性,有机质含量中等,大部分养分含量适宜,应注意追施钾肥、补充硼、镁等微肥。(3)达州烟区白肋烟叶外观质量一般,物理特性和化学成分适宜,感官评吸质量较好。 

Analysis of quality characters of burley tobacco in Dazhou tobacco-growing areas relative to local ecological factors

This paper analyzed the basic conditions in Dazhou tobacco growing areas such as tobacco planting climate factors, soil nutrient status and burley tobacco leaf quality characters. Results show that: (1) Dazhou tobacco growing areas were rich in energy resources, and featured high temperature, precipitation and air humidity. Its landform type featured low hills and low mountains with purple soil, red soil, red yellow soil, alluvial soil and paddy soil being its major soil type. Thus Dazhou tobacco area proved to be suitable for the growth of tobacco. (2)Nutrients were not evenly distributed in Dazhou tobacco-growing soil. Soil in most parts showed weak acidity and had medium level of organic content. Potassium fertilizer, boron, magnesium and other trace elements supplement should be added as supplement. (3) Sensory quality of burley tobacco in Dazhou tobacco growing area was as good as its physical characters and chemical composition and its sensory quality for smoking was relatively good.
