| 摘 要： | 研究表明,烤烟生长期内水分状况的丰缺直接影响烟叶生长、产量和对磷肥的利用率。对叶片生长影响的大小顺序为:上部叶片>中部叶片>下部叶片。所受干旱程度越严重,对叶片生长的抑制作用越明显,产量和磷肥利用率下降越大。生育后期遭遇严重干旱胁迫,对其叶片生长、产量和磷肥利用率的影响最大,生育中期受其影响较小,而在生育前期则几乎不受影响。 |
| 关 键 词： | 土壤水分 烤烟 磷肥利用率 |

| Abstract: | The results of the experiment showed that leaf growth,yields and the utilization of phosphorous fertilizer were affected by soil moisture.Based on the leaf position,the effects of soil moisture on leaf growth were upper leaves > middle leaves > lower leaves.The more severe the drought was,the more seriously the leaf growth,yields and utilization of phosphorous fertilizer were affected.The effects of severe drought on tobacco was biggest in late growing season,smaller in middle season,no or very weak in early season. |
| Keywords: | soil moisture flue-cured tobacco utilization of phosphorous fertilizer |
