摘  要：
为探究不同烤烟品种的适宜施氮量,以K326、OX2028、NC2326、云烟87、红花大金元5个烤烟品种在全国4个烤烟产区采用小区试验方式进行了在当地习惯施肥量基础上增施和减施氮肥对烤烟品种主要化学成分及产量和质量影响研究。试验结果表明:在当地习惯施肥量基础上适度增加施氮量有助于提高K326、红花大金元、OX2028 3个烤烟品种的产量和产值;施氮量的改变对5个供试品种的烤后烟叶主要化学成分影响较小;适度增加施氮量有利于K326、红花大金元2个烤烟品种香气品质的提升,而不同施氮量处理对OX2028、NC2326及云烟87 3个烤烟品种的评吸质量影响较小。在当地施氮量基础上,适度增加K326、红花大金元烤烟品种施氮量有利于提高烤烟种植经济效益,提高烟叶香气质量。

摘  要：
In order to explore the suitable nitrogen application rate of different flue-cured tobacco varieties, five flue-cured tobacco varieties, such as K326, OX2028, NC2326 and Yunyan 87, Honghuadajinyuan, were used in four flue-cured tobacco producing areas of China. The effects of increasing or decreasing nitrogen application rate on the main chemical composition, development, yield and quality of flue-cured tobacco varieties were studied. The test results show that based on the local customary fertilization amount: The yield and output value per unit area of K326, Honghuadajinyuan and OX2028 were improved by increasing nitrogen application amount moderately. The increase or decrease of moderate nitrogen application had little effect on the chemical composition of flue-cured tobacco leaves of five tested varieties. Moderate increase of nitrogen application rate is beneficial to the improvement of aroma quality and smoking quality of K326 and Honghuadajinyuan, while the effect of increasing or decreasing nitrogen application rate on smoking quality of OX2028, NC2326 and Yunyan87 is not significant. Therefore, based on the local nitrogen application rate, increasing the nitrogen application rate of K326, Honghuadajinyuan moderately is beneficial to improve the economic benefits of flue-cured tobacco cultivation and improve the aroma quality of tobacco leaves.
