摘要：

以烤烟品种K326为供试品种,用盆栽方法研究了不同土壤容重对烤烟生长发育和产量及品质的影响。结果表明,土壤容重增大,烟株的生长发育延迟,植株的株高和叶面积生长受到抑制。土壤容重对烟株根系的影响是先促进后抑制,当容重达1.45 g/cm^3处理时根系发育最好,之后当容重继续增大时,根系生长发育受到明显抑制。土壤容重加大,烟叶产量随之降低,当容重达1.65 g/cm^3处理时,烟叶产量比对照降低了82.6%,所产烟叶基本无价值。容重对烟叶品质也产生一定的影响。

Abstract:

Effect of different soil bulk density on growth, yield and quality of K326 flue-cured tobacco variety was investigated by pot experiment. The results indicated that the tobacco growth was obviously delayed, and the plant height and leaf area index were seriously retarded with increase of soil bulk density. The growth of tobacco root was improved when the soil bulk density increased and reached 1.45 g/cm^3, but it was obviously inhibited if the soil bulk density was greater than 1.45 g/cm^3. The tobacco yield decreased with increase of the soil bulk density. The yield was of 82.6% lower than the control when the soil bulk density was 1.65 g/cm^3. The soil bulk density also had certain impact on tobacco leaf quality.

Key words: soil bulk density, flue-cured tobacco, growth , yield , quality
