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.
The effects of different ridge-forming manners and K application on the K absorption and quality of flue-cured tobacco were studied in 2005. The results showed that the ridge-filling and K-application in different culture soils could increase the K content of tobacco leaves, The output value of tobacco leaves, the average price and the proportion of superior tobacco increased with different degrees, and the total amount of neutral aroma compounds in tobacco increased, while the carotenoids, phenylalanines, browning products, neophytadiene, etc. The contents of aroma components were greatly improved compared with the control.Using ridge with low ridges and furrows twice, the effect of K application on the potassium content and quality of tobacco leaves was the best when foliar application of domestication and domestication.
