杈烟对烤烟生长发育及产质量的影响

Effects of Branch Reservation on Growth,Yield and Quality of Flue-Cured Tobacco

为进一步改善烟叶品质、增强烟叶可用性、满足工业企业原料需求,以烤烟品种云烟87为供试材料,研究留杈烟处理对烟株留叶数、上二棚烟叶化学成分、产量产值和各部位叶片比例的影响。结果表明,烟株留杈烟可增加烟株的有效留叶数,使上二棚烟叶的化学成分更加协调,提高烟叶的产量产值,增加中部叶比例。

In order to improve the quality of tobacco leaves,enhance the usability of tobacco leaves and satisfied the industrial demand for raw materials,we studied the effects of branch reservation treatments on the numbers of leaves,chemical composition of the upper two leaves tobacco,yield and output value and proportion of leaves in different parts using the flue-cured tobacco variety Yunyan 87 as material.The results showed that the number of effective leaves increased,the chemical composition of the upper-two-leaf tobacco became more harmonious,the yield and output value of the tobacco leaves increased as well as the proportion of the middle leaves by reserving branch tobacco.
