试验设置4种肥水耦合处理,研究了肥水耦合对一次性采收的上部烟叶产量和品质的影响。结果表明,不同肥水耦合,对一次性采烤上部6片烟叶各个处理产量的影响无显著差异;但烟叶主要化学成分指标、外观质量指标和感官评吸指标有显著差异,且上等烟和中上等烟比例有显著差异,导致产值之间有显著差异。90%的常规施肥量+灌溉水量1 800 m3/hm2的处理烟叶糖分含量高,感官评吸质量最好,产值也最高,产量达2 673.5 kg/hm2,产值达45 829.0元/hm2。
Four kinds of fertilizer and water coupling treatments were set up to study the effects of fertilizer and water coupling on the yield and quality of the upper tobacco collected once. The results showed that the coupling of different fertilizer and water had no significant difference on the yields of six tobacco leaves treated by one-time roasting, but the main chemical components, appearance quality indexes and sensory evaluation indexes of tobacco were significantly different, There are significant differences in the proportion of superior tobacco, resulting in significant differences between the output value. 90% of the conventional fertilizer + irrigation water volume of 1 800 m3 / hm2 treatment of tobacco leaf sugar content, sensory evaluation of the best quality, the highest output value, the output reached 2 673.5 kg / hm2, the output value of 45 829.0 yuan / hm2.
