烤烟是一种重要的经济作物,烟叶品质与环境因素密切相关。在皖南能种植烤烟已确信无疑,关键是能否生产出优质烟叶。对这方面,省内外有关专家近年来作了不少有益的探讨,但大多是从宏观角度出发的。本文试从生态角度出发,着眼于环境因素(气候、土壤),对皖南能否生产出优质烟叶作一分析。(一)土壤土壤虽对烟叶品质影响较大,但烟草对土壤的要求并不严格。有关研究结果表明,烟草喜微酸性到中性土壤,过酸或过碱(pH<4.5,pH>8.5)、过肥沃或瘠薄土壤,都不利于烟草的生长。烤烟宜种植在 Flue-cured tobacco is an important cash crop, and its quality is closely related to environmental factors. In southern Anhui can be planted to flue-cured tobacco has no doubt that the key is whether to produce high-quality tobacco. In this regard, relevant experts both inside and outside the province have made many useful discussions in recent years, but mostly they are from a macro perspective. This paper attempts to proceed from the ecological point of view, focusing on environmental factors (climate, soil), to produce high-quality tobacco in southern Anhui for an analysis. (A) Soil Soil Although the quality of tobacco leaves have a greater impact, but the tobacco requirements of the soil is not strict. The results of the study show that the tobacco is slightly acidic to neutral soil, too acid or over base (pH <4.5, pH> 8.5), over fertile or barren soil, are not conducive to the growth of tobacco. Flue-cured tobacco should be planted in
