烟叶属于茄科，是一年生草本植物。原产美洲，明代万历年间传入中国。在历史上，烟叶种植一直被作为副业，建国后三十年间，本县烟草生产业并未引起足够的重视。1982年，河南省农林科学院烟草研究所在灵宝县苏村乡（属崤山地区）栽种优质烟，通过三年试种取得成功。
      
    灵宝县海拔高，昼夜温差大，雨量适中，土壤适宜，与云贵高原的自然气候条件相似，对烟草的生长发育和优良品种的形成非常有利，灵宝烟叶形成了独有的特点，尼古丁含量适中，外观质量好，烟叶组织细致，油分充分，弹性好，单叶重5克以上色泽鲜亮，颜色金黄，香气质好，吃味醇和。
     
    1985年，在三年试种的基础上，县委、县政府按照调整农村产业结构的精神，在苏村、五亩、朱阳、川口、尹庄、阳店、大王、寺河、阳平、程村、故县和豫灵等十二个乡大面值种植烟叶。
