不同移栽期对特色烤烟品种翠碧一号生长发育及产质量的影响

Effects of Different Transplanting Time on Growth,Development,Yield and Quality of Flue-cured Tobacco Variety CB-1

为寻找特色烤烟品种翠碧一号在福建三明烟区较为适宜的移栽期,采用多年试验方法探讨了不同移栽期对翠碧一号烤烟生长及产质量的影响。结果表明,三明烟区在当年常规移栽期及避开极端低温气候影响的基础上,可因地制宜适当提早移栽期,不仅有助于烟株早生快发,促进烟株生根期的生长发育,有效叶片数和叶面积系数增加较快,烟株生长较为老健,抗逆性有所提高,适当延长了烟株大田有效生育期,而且产量和产值均较高且稳定。

In order to find the suitable transplanting time of flue-cured tobacco variety CB-1 in Sanming,the effects of different transplanting time on growth and quality were studied by multi-years method. In Fujian Sanming tobacco area,on the basis of conventional transplanting,appropriate early transplanting was helpful for early growth and quick tillering of tobacco plants,tobacco plants had better growth and development,leaf number and leaf area increased rapidly,the growth was robust,the stress resistance was improved,and had effective longer growing period,and it could help to improve the acre yield and output.
