不同覆膜移栽方式对烤烟生长发育的影响

Effects of Different Methods of Transplanting with Film Mulching on Flue-cured Tobacco Growth

采用田间试验和生物统计学上的单因素随机区组设计,研究不同覆膜移栽方式对烤烟品种‘翠碧1号’生长发育规律的影响。结果表明:与膜上深栽比较,膜下移栽处理的根系、叶片和整株生物量,以及不同部叶片平均单叶重明显上升;不同的移栽方式对烤烟的各个生长部位生物量的积累影响较大,到采收结束时,膜下移栽处理的下部叶、中部叶和上部叶平均单叶重分别比膜上移栽提高24.74%、10.2%和18.94%。结合福建烤烟生产季节的气候状况,认为福建烤烟膜下移栽有利于烟株的生长和烟叶品质的改善。

The effects of different methods of transplanting on growth and development of the Nicotiana tabacum L.＇CB-1＇ were discussed by field trails and the single factor analysis in biostatistics.The obvious influences on the growth and development in tobacco were revealed by different methods of transplanting with film mulching.The biomass of roots,leaves and whole plants,weight per leaf by up-film transplanting were decreased obviously compared to down-film transplanting.Great influences on accumulation of different parts of tobacco with different methods of transplanting were observed.The weight per leaf of lower leaves,middle leaves and upper leaves with down-film transplanting were raised by 24.74%,10.2% and 18.94% respectively compared to up-film transplanting at last harvest.Based on climate conditions in Fujian,down-film transplanting was helpful to tobacco growth and quality improvement.
