| Abstract: | To study the dynamic changes of some biochemical substance, such as sugar, nitrogen and nicotine etc, in the burley tobacco under the soil conditions with various N, P, K amount, the tobacco leaf was sampled, dried and detected at different growth stage. The results showed that the contents of total sugar and reducing sugar increased with the plant growing and developing, whereas the content of total nitrogen and protein decreased. The contents of total nitrogen, protein and nicotine in leaves were enhanced with the increase in N fertilizer applied to the soil at every growth stage, but the content of total sugar at fully growing and leaf mature stage, as well as the reducing sugar at rooting, pre-fully growing and leaf mature stage declined. With the increase in P fertilizer applied to the soil, the content of total nitrogen at every growth stage, protein and nicotine contents at the rooting, pre-fuUy growing and leaf mature stage, increased, whereas the total sugar content at fully growing stage, reducing sugar at pre-fully growing and protein and nicotine contents at post-fully growing decreased. With the increase in K fertilizer applied to the soil, the content of total nitrogen and nicotine at every growth stage declined. It was concluded that N and K fertilizer could influence stronger the contents of total sugar and reducing sugar, whereas N and P fertilizer could do that to the contents of nicotine, total nitrogen and protein. |
