摘要
以秦烟96为试验材料,研究了二次打顶措施对烤烟经济性状及化学成分的影响。结果表明,烤烟二次打顶后,产量略有降低,平均减少5.55%,但产值、均价和中上等烟比例都大幅提升,平均分别增加了7.02%、13.33%、8.35%。这表明二次打顶可不同程度上影响各部位烟叶化学成分含量,改善化学成分协调性。
Taking tobacco cultivar Qinyan96 as material, the effects of double tip-pruning on economic characters and chemicalcomposition in flue-cured tobacco was explored. The results showed that double tip-pruning can make the per mu yield reduced by 5.55%,butincrease the per mu output value,the average price and the ratio of middle to superior grade tobacco by 7.02%,13.33% and 8.35%. Doubletip-pruning could obviously impact the chemical composition of flue-cured tobacco in different part, and improve the coordination of thechemical composition much more.
