| 摘 要： | 2005年研究了不同成垄方式及分次施钾对烤烟钾素吸收和品质的影响.结果表明,不同培土成垄和分次施钾可以提高烟叶钾含量,协调烤后烟叶化学成分比例,使烟叶的产值、均价、上等烟比例均有不同程度的提高.并使烟叶中性致香物质总量增加,类胡萝卜素类、苯丙氨酸类、棕色化产物、新植二烯等致香物质含量均较对照有很大提高.以低起垄两次培土成垄,团棵期、圆顶期分次施钾对烟叶的钾含量和品质效应最好. |

| Abstract: | A study was carried out on the effects of different ridging mode and applying potassium fertilizer at different stages on the contents of potassium and leaf quality of flue-cured tobacco(Nicotiana tobacum L.) in 2005.The results showed that different ridging by earthing up after planting and applying potassium fertilizer at different stages can increase the content of potassium,the yield,the average price,the proportion of superior tobacco leaves had different degrees of improvement,and can also increase the total content of neutral aroma components.Compared with the common cultivation,the contents of carotenoid,phenylalanine,products of browing reaction and neophytadiene were greatly increased in every treatment.The content of potassium and the tobacco leaf quality in the treatment of ridging by low planting and applying potassium fertilizer at rosette and toping stage respectively are better than any other treatment. |
| Keywords: | flue-cured tobacco ridging mode applying potassium fertilizer at different stages chemical components aroma composition |
