摘要
海拔高度会影响当地土壤养分含量和气候情况等生态因子,从而对植烟地区当地烟叶外观质量、内在质量、感官质量等烟叶品质产生影响。在一定范围内,适当提高植烟海拔高度,对降低上部烟叶烟碱含量、提高烟叶钾含量均有明显作用。
The nutrient content of soil and the ecological factors as climatic conditions, etc. were affected by the altitude of tobacco-planting areas. So the effects of altitude on the quality of tobacco （appearanee quality, intrinsic quality and smoking quality） were obvious. Within a certain range, appropriately increasing the ahitude of tobacco-planting areas could reduce the nicotine content of upper leaves and increase the contents of K in tobacco leaves.
