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

The vield and nicotine content of flue-cured tobacco are better in the southern Jiangxi than in the middle and northern．The average yield is 1920．Okg／hm² in the south，1698．Okg／hm² in the middle，and 1705．5kg／hm² 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 clim atic condition in each development stage according tO the yield and quality of flue-cured tobacco，the paper confirms the priority and requirements of light，temperature and water in each development stage and puts forward some cultivating countermea sures．
