施氮量对海南五指山雪茄生长发育及品质的影响

Effects of Nitrogen Application Rate on Growth and Quality of Cigar in Hainan Wuzhi Mountain

通过田间试验和化学分析等方法,研究了4个施氮量(90,135,180,225 kg/hm2)对烟株生长发育及烟叶品质的影响。结果表明,施氮量对雪茄的前期生长发育以及中性香气含量影响显著;与其他3个施氮量相比,施氮量为180 kg/hm2时,雪茄的农艺性状、烟叶化学成分及中性致香成分大部分指标较优。表明在该试验条件下,每公顷施氮180 kg时雪茄综合表现最好,优势得以充分展现。

The effects of four nitrogen application rates （90, 135, 180, 225 kg/hm）on the growth and quality of flue-cured tobaccowere studied by field experiment and chemical analysis. The results showed that the amount of nitrogen had significant effects on the earlygrowth and neutral aroma content of cigar. Compared with the other three nitrogen application rates, the agronomic traits, tobaccochemical components and neutral aroma components of the cigar were the best indicators when the amount of nitrogen was 180 kg/hm2.The results show that under the experimental conditions, when the application of nitrogen is 180 kg/hm2, the comprehensive performanceof cigars is the best, the characteristics can be fully displayed.
