中文摘要:
      为探索施氮量与优化烟叶结构耦合效应提高烤烟品质,以K326为材料,研究了不同施氮量与优化烟叶结构耦合对烤烟生长发育及产质量的影响。结果表明:施氮量和优化烟叶结构耦合能够影响烤烟的生育期,有利于上部叶采收成熟度的提高,烤烟农艺性状主要与施氮量有关。烤烟的经济效益随着施氮量的增加呈现先升高后降低的规律,优化烟叶结构能提高烤烟的经济效益。施氮量和优化烟叶结构耦合能够促进烤烟各部位烟叶的化学成分更加协调。综合来看,以施氮量在7.5 kg/667m2水平时进行优化烟叶结构的效果最佳。
英文摘要:
      The paper aims to explore the coupling effect of nitrogen application rate and optimization of tobacco structure on the growth, yield and quality of flue-cured tobacco by using‘K326’as the material. The results showed that: the coupling of nitrogen application rate and optimization of tobacco structure could affect the growth period of flue-cured tobacco, which was beneficial to improving the harvesting maturity of upper leaves, and the agronomic characters of flue-cured tobacco were mainly related to nitrogen application rate. The economic benefit of flue-cured tobacco first increased then decreased with the increasing of nitrogen application amount, and the optimization of tobacco structure could improve the economic benefit of flue-cured tobacco. The coupling of nitrogen application rate and optimization of tobacco structure could promote the coordination of the chemical compositions of flue-cured tobacco leaves. In summary, the optimal effect could be obtained by the optimization of tobacco structure under the nitrogen application rate of 112.5 kg/hm2.
