烤烟是卷烟工业的原料,对品质有严格的要求。五十年代,河南的烤烟品质在国内外享有较高的声誉,但自七十年代以来,品质逐渐下降,在国内外市场上引起强烈的反响。因此,如何提高烤烟品质,就成为当务之急。据分析,影响河南烤烟品质的因素很多,归纳起来有四个问题:合理布局与盲目种植问题,质量与产量问题,内在品质与外观品质问题,烤烟生产与粮食生产问题。只有统筹解决这些问题,才能从根本上提高河南烤烟的品质。一、合理布局与盲目种植问题烤烟品质与土壤、气候等条件密切相关。河南烟草区划研究证明,省内大多数地区都可种烟,但不同地区的产品,质量差异很大。按地貌说,丘岗烟叶质量高于平原,平原高于低地。按土壤说,以红粘土烟质最好,依次为红黄土、沙壤土、立黄土、黑粘土。按气候说, Flue-cured tobacco industry is the raw material, the quality of the strict requirements. In the 1950s, the quality of flue-cured tobacco in Henan enjoyed a high reputation both at home and abroad. However, its quality has been declining since the 1970s, arousing strong repercussions in domestic and overseas markets. Therefore, how to improve the quality of flue-cured tobacco has become a top priority. According to the analysis, there are many factors that affect the quality of flue-cured tobacco in Henan Province. There are four problems to be summed up: rational distribution and blind planting, quality and yield, inherent quality and appearance quality, flue-cured tobacco production and grain production. Only by co-ordinating the solution to these problems can we fundamentally improve the quality of Henan tobacco. First, the rational distribution and blind cultivation issues Flue-cured tobacco quality and soil, climate and other conditions are closely related. Henan tobacco zoning studies have shown that most areas in the province can grow tobacco, but different regions of the product, the quality is very different. According to the landscape, the quality of flue-cured tobacco in Hutang is higher than that in plain and the plain is higher than lowland. According to the soil, the best is red clay, followed by red loess, sandy loam, loess and black clay. According to the climate,
