中文摘要:
      通过田间试验和化学成分分析等方法,研究不同施氮水平对烤烟品种‘湘烟5 号’农艺性状和产质量的影响,为其大面积生产推广提供依据。结果表明,施用纯氮135~142.5 kg/hm2能促进烟株正常生长,形成“中棵烟”株型,适时落黄成熟,烤后烟叶呈现叶片结构疏松、身份中等、色泽浓、油分多、颜色多橘黄的外观特征;不同施氮水平均对烟叶的产量、产值、均价、上中等烟比例等经济性状因素产生影响,其中以T2 处理(135 kg/hm2)影响效果最佳,产量较常规增加370.35 kg/hm2,提高了15.12 个百分点;产值较常规增加12374.4 元/hm2,提高了21.82 个百分点;均价较常规增加1.34 元/kg,提高了5.78 个百分点;上等烟率较常规提高了6.01百分点,且烤后的糖碱比、氮碱比、钾氯比均较适宜,烟叶内在化学成分较协调。因此,建议以纯氮135 kg/hm2为‘湘烟5号’在湘南烟区推广种植的最佳施用量。
英文摘要:
      Field experiments and chemical components analysis were conducted to study the effects of different nitrogen application amounts on agronomic traits, yield and quality of flue-cured tobacco variety‘Xiangyan 5’, to provide a basis for large scale extension. The results showed that 135-142.5 kg/hm2 pure nitrogen could promote the normal growth of tobacco plants, form“medium tobacco plants”type and ensure leaf mature at moderate time. The flue-cured tobacco leaves had appropriate thickness with loose structure, medium identity, dense color, rich oil content and mainly in golden color. Different nitrogen application amounts affected tobacco economic factors, such as yield, output value, average price, and the proportion of upper- middle tobacco. T2 treatment (135 kg/hm2) had the best effects, compare with the control, the yield increased by 370.35 kg/hm2, 15.12 percentage, the output value increased by 12374.4 yuan/hm2, 21.82 percentage, the average price increased by 1.34 yuan/kg, 5.78 percentage, the percentage of upper tobacco leaf was raised by 6.01 percentage, and the sugar alkali ratio, nitrogen alkali ratio, and potassium chlorine ratio of flue-cured leaves were suitable, the internal chemical components of tobacco leaves were coordinated. Therefore, it is suggested that 135 kg/hm2 pure nitrogen should be the best rate in plating of flue- cured tobacco variety ‘Xiangyan 5’in southern Hunan tobacco area.
