| 摘 要： | 以云烟85为试材，通过大田试验研究镁、硼对烤烟生长发育和产质量的影响。结果表明：与OPT（推荐施肥）处理相比，缺硼处理烤烟移栽后各生育期推迟3～6d不等，打顶株高、节距、茎围、最大腰叶的长和宽分别降低4．10％、12．67％、13．33％、16．71％和15．57％，根系深度、根系幅度、1级分枝根数、2级分枝根数分别降低33．33％、11．34％、40．oo％、13．51％和31．31％；缺镁处理烤烟的生育期、生长性状、根系指标等与OPT处理相差不大，但经济产量与产值明显降低。说明缺硼会导致烤烟长势差，生育期延迟，根系生长受阻，产量低、品质差，经济效益降低。因此，南方酸性土壤区发展烤烟生产，应合理施用镁、硼肥，以促进烤烟生长发育，提高产量和产值。 |

| Abstract: | The present experiment was conducted to study the effects of magnesium and boron fertilizers on growth and yield of flue-cured tobacco under field conditions in Nandan County,Guangxi.The flue-cured tobacco variety Yunyan 85 was used as material and applied with three fertilizer treatments,viz.,magnesium deficiency,boron deficiency and rec-ommendation fertilization(ammonium sulphate @214.2kg/ha,calcium nitrate @119.9kg/ha,potassium nitrate @199.9kg/ha,potassium sulphate @362.0kg/ha,calcium magnesium phosphat... |
| Keywords: | flue-cured tobacco magnesium deficiency boron deficiency growth and development yield quality |
