| Abstract: |
| In order to explore the basal-topdressing ratio of tobacco field and improve the tobacco quality.
Fluecured tobacco yunyan87 was taken as an experimental material to study the effect of different basal-topdressing
ratio on tobacco agronomic trait，yield，quality，and nutrition properties. The result revealed that there were no
significant differences between different nitrogen basal-topdressing ratios on tobacco agronomic trait，while the
significant difference was observed on yield in treatment of 5∶5 basal and topdressing. The yield and quality was
improved by 20.77% and 5.22%，respectively. The physical and chemical properties and coordination of tobacco
in the range of middle to high quality as compared with the control. It could be concluded that the 5IE5 basaltopdressing
ratio of nitrogen was positive on the yield and quality of flue-cured tobacco（ yunyan 87）. |
