| 摘 要： | 为了寻求协调烟叶内部化学成分、提高内在品质的施肥水平的最佳组合,进行了不同氮用量对烤烟产量及内在品质的影响试验.结果表明:各处理的公顷产量随着施氮量的增加而升高,公顷产值、上等烟比例、中等烟比例和均价也随着施氮量的增加而升高,但每公顷施纯氮超过75kg之后开始下降;化学成分分析中,烟碱、总氮、蛋白质含量从各处理上来看,每公顷施氮75kg的处理各项指标均优于其他处理;从评吸结果来看,每公顷施氮75kg处理的烟叶香气较丰富,饱满,杂气较轻,余味微滞.综合考虑各项因素,每公倾施氮75kg的处理组合最佳.

| Abstract: | To harmonize immanent chemical components in tobacco leaves and to improve immanent quality,the experiment on the effects of different N rates on flue-cure tobacco growth and immanent quality was performed.The results showed in every treatment,yield increased steadily along with N rate increase and output value,proportion of superior leaf and medium leaf,and average price also increased steadily along with N rate increase,but they decreased when N rate was more than 75 kg/hm2;the content of nicotine,total n... |
