邵阳稻田烤烟留叶数研究

Research on Remaining Leaf Number of Paddy Flue-Cured Tobacco in Shaoyang

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。

This paper studies the agricultural property,physical characteristics,economic character and chemical composition of the different number of remaining leaves of flue-cured tobacco Yunyan 87. The results showed that with the decrease in the number of remaining leaves,stem length,yield,output value,labor quantity gradually decreased,coal consumption and electricity consumption decreased,weight per unit area of the middle and upper leaves increased,average price increased. The treatment of 16 leaves with good physical properties,coordinating chemical composition,high price value,high output value,high ratio of superior and middle tobacco leaves,low labor quantity,low energy consumption,net output just below the treatment of 20 leaves,treatment of 16 leaves can consider to be applied in production.
