煙葉屬于茄科，是一年生草本植物。原產(chǎn)美洲，明代萬歷年間傳入中國。在歷史上，煙葉種植一直被作為副業(yè)，建國后三十年間，本縣煙草生產(chǎn)業(yè)并未引起足夠的重視。1982年，河南省農(nóng)林科學(xué)院煙草研究所在靈寶縣蘇村鄉(xiāng)（屬崤山地區(qū)）栽種優(yōu)質(zhì)煙，通過三年試種取得成功。
      
    靈寶縣海拔高，晝夜溫差大，雨量適中，土壤適宜，與云貴高原的自然氣候條件相似，對煙草的生長發(fā)育和優(yōu)良品種的形成非常有利，靈寶煙葉形成了獨(dú)有的特點(diǎn)，尼古丁含量適中，外觀質(zhì)量好，煙葉組織細(xì)致，油分充分，彈性好，單葉重5克以上色澤鮮亮，顏色金黃，香氣質(zhì)好，吃味醇和。
     
    1985年，在三年試種的基礎(chǔ)上，縣委、縣政府按照調(diào)整農(nóng)村產(chǎn)業(yè)結(jié)構(gòu)的精神，在蘇村、五畝、朱陽、川口、尹莊、陽店、大王、寺河、陽平、程村、故縣和豫靈等十二個鄉(xiāng)大面值種植煙葉。
