Effects of BD fertilizers，in which basal fertilizer and dressing fertilizer were microencapsulated respectively， on characteristics agronomy and economy of the flue-cured tobacco were studied by field plot trial and field demonstration project. The results showed that flue-cured tobacco，with dosage of BD fertilizer at 1 200 kg/ hm2，had a better growth，and presented a quality leaf appearance and a more coordinated chemical composition. In field plot trial，when one single basal application dosage of BD fertilizer was 0.135 kg/m2，the production value was 16.41% significantly higher than that of the control at 0.01 level. In field demonstration project，when the single basal application dosage of BD fertilizer was 1 350 kg/hm2，the production value was 14.58% significantly higher than that of the control，and the production value was significantly increased by 14.17% with the application dosage of 1 200 kg/ hm2. To some extent，the aroma character of the flue-cured tobacco was affected by BD fertilizer application and the offensive odor and after-taste were also improved in comparison to the control. Among them，the plants with the application dosage of 1 200 kg/hm2 was found to be the best．
