施氮量和留叶数对中烟100产质量的影响

Effects of Nitrogen Rates, Leaves of Tobacco Remained on Yield and Quality of Flue-cured Tobacco Zhongyan100

摘要: 通过田间试验,研究了不同施氮量和留叶数对烤烟中烟100产量和质量的影响。结果表明,施氮量和留叶数对中烟100的农艺性状和经济性状均有显著影响；各处理烟叶还原糖、总糖、总植物碱等化学成分差异性都达到极显著水平；施氮量90 kg/hm²、留叶数18片和22片处理的化学成分较适宜,感官质量较佳。综合分析认为,在当地生态条件下,施氮量为90 kg/hm²,留叶数为18～22片,中烟100有较好的产值量和较佳的烟叶质量

Abstract: The effects of nitrogen rates and leaves of tobacco remained on growth, yield, value and quality of flue-cured tobacco Zhongyan100 were studied by use of field experiments in Lichuan, Hubei province. The results showed that the effects of nitrogen rates and leaves of tobacco on growth condition in fields and yield were significant. The reducing sugar content, total sugar content, total plant alkaloid and other chemical composition in tobacco leaves between treatment were significantly different. The highest aroma quality, amount of aroma, aftertaste and total score were found treatment of 90 kg N/ha with 18-22 leaves remained.Therefore, this nitrogen rate and the number of leaves remained are recommended for tobacco production in this region.
