Study on Cultivation Technology of New Flue-cured Tobacco Variety FG-1

[Objective] The aim was to form the corresponding cultivation and application technology of the new flue cured tobacco variety FG-1.[Method] The effects of planting density and nitrogen application rate on the growth and development and yield of the new flue cured tobacco variety FG-1 were researched,by setting up different planting densities and nitrogen application rates experiments in Guizhou Province.[Result] The effect of the different planting densities and nitrogen applying rates on the FG-1 were not distinct.The FG-1 has most desirable growth and yield with 112.5 kg/hm2 nitrogen applying.And with treatment of spacing of 70 cm,110 cm row spacing planting and 105.0 kg/hm2 nitrogen applying,the high–middle-quality ratio and output of FG-1 were higher than that of other treatments,and the overall performance was the best.[Conclusion] The result of the study showed that FG-1 had a better grew and economic indicators with spacing of 70 cm,110 cm row spacing planting and 105.0 kg/hm2 nitrogen applying.
