通过小区和大田示范试验,研究了基肥和追肥分别造粒的烟草专用缓释肥(BD肥)对烟草农艺和经济性状的影响.结果表明:当BD肥施用量为1 200 kg/hm~2时,烟株田间长势长相、初烤烟叶外观质量较好,烟叶化学成分更趋协调.小区试验中,当一次性施用BD肥0.135 kg/m~2时,初烤烟叶产值比对照极显著增加16.41%;大田示范试验中,当一次性施用BD肥1 350 kg/hm~2时,初烤烟叶产值比对照显著增加14.58%,而一次性施用BD肥1 200 kg/hm~2时其产值则显著增加14.17%.BD肥对初烤烟叶香气有一定影响,且其杂气、余味均较对照好,其中以一次性施用BD肥1 200 kg/hm~2的烟株表现最好.

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/ hm~2,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/m~2,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/hm~2,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/ hm~2. 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/hm~2 was found to be the best.
