基追肥比例对烤烟产质量及烟叶香气的影响

Effects of Proportion of Basal and Topdressing Fertilizers on Yield,Quality of Flue-cured Tobacco and Incense

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 seek the best effects of proportion of basal and topdressing fertilizers and tobacco incense, a field experiment was conducted that effects of proportions of basal and topdressing fertilizers on yield, quality of flue-cured tobacco and incense, the 6 proportions included 8：2, 7：3, 6：4, 5：5, 3：7 and total topdressing fertilizers. The results showed that： The plant height, the biggest stem girth and the longest leaf length, yield, average price and proportion of high and middle grade of 3：7 （T5） respectively reached 97.00, 9.37, 66.90 cm, 3 687.98 kg/hm^2, 13.48 Yuart/kg, 86.54% , which were of highest among 6 proportions of basal and topdressing fertilizers. （2） The contents of substance to fragrance of proportion of 8： 2 （ T1 ） reached 474. 36 μg/g, which was the maximum among the 6 proportions. The proportion of base fertilizer and topdress second with 469.43 μg/g. That of the proportion 5： 5 （T4） was the ing fertilizers 7： 3 （T2） rank the minimum with 383.38 μg/g.
