摘要: 为筛选出最优的肥料基追比例和追肥时间,提高烤烟肥料利用率,改善烟叶品质,设置6 个处理和1 个对照,研究不同追肥量和追肥时间对‘云烟105’烤烟品种品质和经济效益的影响。结果表明,与对照相比,在云南曲靖宣威植烟区,施用纯氮量为97.5 kg/hm2,基追肥比例为70%:30%,于烤烟移栽后25 天追施硝酸钾肥料能促进‘云烟105’烤烟正常生长,改善烟株田间农艺性状,使烟叶内在化学成分更协调,改善抽吸品质。其中,烟叶化学成分协调性平均提高14.03%,感官评吸质量平均提高2.93%,并能使中上等烟比例、产量、产值和均价等经济指标等分别提高5.05%、4.79%、9.98%和5.45%,经济效益明显。

Abstract: To seek the best proportion of basal and topdressing fertilizers and time of topdressing, increase the fertilizer utilization efficiency and improve quality of flue- cured tobacco, a field experiment (including 6 treatments and 1 contrast) was conducted in Xuanwei, Yunnan Province, to investigate the effect of different topdressing amounts and time on the quality and economic benefits of‘Yunyan 105’. The results showed that, compared with control, the treatment with 97.5 kg pure nitrogen per hectare, basal and topdressing fertilizer proportion as 70% :30% , and the topdressing of potassium nitrate 25 days after flue- cured tobacco transplanting could promote the regular growth, improve the agronomic characters, coordinate the chemical compositions of tobacco leaves and enhance the smoking quality. Among them, the composite index of chemical compositions was improved by 14.03%, the composite index of smoking quality was improved by 2.93%. In addition, the ratio of mid-high grade leaves, the per hectare yield, the output value and the average price of tobacco leaves increased by 5.05%, 4.79%, 9.98% and 5.45%, respectively, compared with those of control, and the economic benefits were obvious.
