为了寻求最适合的肥料基追比例对烟叶产质量及其与烟叶香气的关系,进行了基追肥比例8:2,7:3,6:4,5:5,3:7和全追肥共6个处理,对烤烟烟叶产质量及烟叶香气的影响试验。结果表明:基追比3:7(T5)的株高、茎围、叶长最大,分别达到了97.00,9.37,66.90 cm。T5产量、均价、上中等烟比例最高,分别达到了3687.98 kg/hm~2,13.48元/kg,86.54%。基追比8:2(T1)致香物质含量最高,为474.36μg/g,其次是7:3(T2),为469.43μg/g,5:5(T4)致香物质含量最低,为383.38μg/g。
In order to find out the most suitable ratio of fertilizer base and dressing to yield and quality of tobacco leaf and its relationship with the aroma of tobacco leaves, the ratio of base dressing to top dressing was 8: 2, 7: 3, 6: 4, 5: 5, 3: A treatment, the quality of tobacco leaves and tobacco flavor aroma test. The results showed that the plant height, stem circumference and leaf length of the 3: 7 (T5) were the largest, reaching 97.00, 9.37 and 66.90 cm respectively. T5 production, average price, the highest proportion of middle-grade tobacco, respectively, reached 3687.98 kg / hm ~ 2, 13.48 yuan / kg, 86.54%. The top-aroma ratio was 8: 2 (T1), with the highest aroma content of 474.36μg / g, followed by 7: 3 (T2) at 469.43μg / g, the lowest content of aroma at 5: 5 μg / g.
