研究了同一海拔高度种植不同海拔高度选育的烟草种子对烤烟产质量的影响。结果表明,在海拔高度1 150 m处种植800、1 000、1 500 m海拔高度选育的烟草种子时烤烟生育期没有差异,而农艺性状略有差异。烤烟产量受海拔高度的影响,不同海拔高度之间烤烟产量最大相差65 kg/hm2。800、1 000、1 500 m海拔高度选育的烟草种子在海拔高度1 150 m处种植会影响烤烟中烟碱、总糖、总氮、钾和氯的含量。
The effects of planting tobacco seeds at different elevations on the same altitude on the yield and quality of flue-cured tobacco were studied. The results showed that there was no difference in the growth period of flue-cured tobacco while the agronomic characters were slightly different when the seeds were planted at the altitude of 1 150 m at the altitude of 800, 1 000 and 1 500 m. The yield of flue-cured tobacco was affected by the altitude. The maximum difference of the yield of flue-cured tobacco between different altitudes was 65 kg / hm2. Tobacco seeds of breeding at altitude of 1,800,1 000,1 500 m were planted at 1 150 m above sea level, Alkali, total sugar, total nitrogen, potassium and chlorine content.
