| Abstract: | Effects of light intensity on the mineral elements,main chemical components and phys-ical 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. |
