不同播期对烤烟品种烟叶主要化学成分及其经济性状的影响

试验于2009～2010年在广东韶关进行,设置正常播期（12月1日）、晚播（12月11日）、晚播（12月21日）3个播期,研究播期对烤烟品种成熟期的化学成分变化及其经济性状的影响。结果表明,播期严重影响烤烟成熟期化学成分变化和烤后烟叶的经济性状。随播期推迟,各品种的株高变矮,有效叶数减少,最大叶面积减小,影响烤烟产量。随播期的推迟,烤烟上部叶中总氮含量、烟碱含量逐渐递减,可溶性糖含量、淀粉含量逐渐递增。导致烤后烟叶B2F、C3F的总氮含量、烟碱含量随播期推迟而减小,淀粉含量随播期推迟而增加。综上所述,在过迟晚播条件下,烤烟的产量下降,烤后烟叶品质降低。...

To investigate the effect of sowing dates on the changes of chemical components and economic character of flue-cured tobacco varieties in ripening period,the field experiments were carried out from 2009 to 2010 in Guangdong Shaoguan,the three sowing dates which was normal sowing date（1 December）,late sowing（11 December） and the later sowing（December 21） were set, the results showed that sowing date seriously affected the changes of chemical components and economic character of flue-cured tobacco during ripeness.With delayed sowing date,the plant height of all varieties grew shorter,effectively reducing the number of leaves,maximum leaf area was reduced to affect flue-cured tobacco production,meanwhile,the content of total nitrogen and nicotine in the upper leaves gradually decreased,and the content of soluble sugar and starch increased gradually.After roasted tobacco B2F,C3F,in which the total nitrogen content,nicotine content decreases w
