气候生态因素对烤烟产量与品质的影响及植烟措施研究

The yield and nicotine content of flue-cured tobacco ar e better in the southern Jiangxi than in the middle and northern. The average yi eld is 1920.0kg/hm 2 in the south, 1698.0kg/hm 2 in the middle, and 1705.5kg/ hm 2 in the north. The average nicotine content is 22.7g/kg in the south, 18.2g /kg in the middle, and 13.5g/kg in the north. Assaying the climatic condition in each development stage according to the yield and quality of flue-cured tobacc o, the paper confirms the priority and requirements of light, temperature and wa ter in each development stage and puts forward some cultivating countermeasures.
