| 摘 要： | 为阐述植烟土壤各种矿质养分和烟株吸收积累营养的相互关系,采用营养液培养的方法,研究了离子强度为0.0079、0.0159、0.0318、0.0635、0.127 mol/L的营养液,对烟草矿质养分的吸收与积累的影响。结果表明,随着离子强度从0.0079 mol/L提高到0.127 mol/L,烟草生长量呈抛物线型变化,在离子强度为0.0318 mol/L时烟株干物质积累量最大。随营养液离子强度的提高,烟草全株氮、磷含量逐渐增加;钾、锌、钙含量呈抛物线趋势变化,以离子强度为0.0318 mol/L时含量最高,低于或高于0.0318 mol/L,钾、锌、钙含量逐渐降低;镁、铜含量变化与营养液中离子强度的关系和钾、钙、锌等元素相似,而二者的转折点的离子强度分别为0.635 mol/L、0.0159 mol/L;锰含量总是随营养液离子强度的增加而减小,表现为拮抗关系。烟草全株氮、磷、镁、钾、钙、铜、锌等元素积累量均呈抛物线趋势变化,都是以离子强度为0.0318 mol/L达到最大值。 |
| 关 键 词： | 烟草 离子强度 营养液 矿质养分 含量 积累量 |

| Abstract: | Effect of nutrient solution with ionic strength of 0.0079,0.0159,0.0318,0.0635,and 0.127 mol/L on mineral nutrients absorption and accumulation of tobacco were studied.Results showed that as ionic strength changed from 0.0079 mol/L to 0.127 mol/L,tobacco biomass varied in a shape of parabola and peaked at 0.0318 mol/L of ionic strength.Content of N,P in tobacco increased with the increase of ionic strength.Content of K,Zn,and Ca changed in parabola as ionic strength increased and peaked at 0.0318 mol/L.When... |
