气候生态因素对烤烟产量与品质的影响及植烟措施研究

江西省烤烟产量与烟碱含量赣南优于赣中和赣北 ,赣南平均产量为 192 0 .0kg/hm2 ,赣中为 1698.0kg/hm2 ,赣北为 170 5.5kg/hm2 ;平均烟碱含量赣南为 2 2 .7g/kg ,赣中为 18.2 g/kg ,赣北为 13 .5g/kg。简析了该省烤烟各生育期气候条件对其产量和品质的影响 ,确定烤烟各生育阶段对光、温、水要求的主次 ,并提出植烟栽培措施。

The influence of climatic ecology factors on the yield and quality of flue-cured tobacco and the countermeasures of plant ing tobacco in Jiangxi

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.
