摘要
对不同光照强度下烤后烟的矿质元素、主要化学成分、物理特性进行了分析。结果表明:氮、钾、钙、氯、铜、淀粉、还原糖含量,钾/氯,单叶重,叶质重,叶片厚度受光照强度影响较大;铁、锌、总糖含量,含梗率受光照强度影响次之;而磷、镁、平衡含水率受光照强度影响不显著;≥80%全光照适合优质烟叶的生产。
Effects of light intensity on the mineral elements,main chemical components and physical characteristics of flue-cured tobacco were studied. The results shows that the content of N, K, Ca,Cl,Cu, starch and reduced sugar, K/Cl, the single-leaf-weight, leaf weight of unit area, and leaf thickness were greatly influenced by light intensity. The content of Fe, Zn and total sugar,and stalk proportion were suffered secondly. But the content of P,Mg and equilibrium moisture ratio were less affected. It suggested that the light intensity of over 80% is suitable for the growth of flue-cured tobacco.
