以云烟87为材料,研究了邵阳烟区稻田烤烟优化烟叶结构后不同留叶数对烤烟农艺性状、物理性状、化学成分、经济性状的影响。结果表明:随留叶数减少,株高降低,中上部叶叶质重增加,产量降低,产值降低,均价升高,用工减少,耗煤耗电减少;留叶数16片的处理物理性状良好,化学成分协调,优质烟叶比例高,耗煤耗电及用工少,净产值仅次于留叶20片的处理,可以考虑在生产上推广应用。
Yun Yun 87 was used as material to study the effect of different leaves number on the flue-cured tobacco agronomic traits, physical properties, chemical compositions and economic traits after optimizing the structure of tobacco in Shaoyang tobacco-growing areas. The results showed that with the reduction of leaf number, the plant height decreased, the weight of middle and upper leaves increased, the yield decreased, the output value decreased, the average price increased, the labor cost decreased and the consumption of coal consumed decreased. Good, coordinated chemical composition, a high proportion of high-quality tobacco, coal consumption and less labor, net output value after leaves 20 pieces of processing, can be considered in the promotion of production.
