摘　　要：为了明确不同雪茄类型烟草漂浮育苗的适宜剪叶程度,研究了剪叶程度对雪茄烟、白肋烟、烤烟漂浮育苗烟苗生长指标的影响。结果表明:随着剪叶程度的加重,烟苗的高度、茎围、鲜重、干重、根体积和相关成苗素质指标均降低,而茎围/苗高、根冠比、根重比等指标呈增大趋势。剪叶程度越重对烟苗生长的抑制作用越大,但剪叶能协调烟苗根系与地上部分的比例,协调烟苗茎围与高度的比例。雪茄烟、白肋烟、烤烟漂浮育苗的剪叶应根据烟苗整齐度、长势和移栽计划灵活掌握。In order to determine the suitable leaf-cutting degree of floating tobacco seedlings of cigar type,the test about different leafcutting degree of different types of tobacco was set up,the effects of leaf-cutting on seedling growth index of flue-cured tobacco,burley tobacco and cigar tobacco was studied.The result showed that,the height,stem circumference,fresh weight,dry weight,root volume and seedling quality indexes of tobacco seedlings were decreased with the increase of leaf cutting degree,but stem girth/seedling height,root shoot ratio and root weight ratio were increased with the increase of leaf cutting degree.The greater the degree of leaf cutting,the greater the inhibition effect on the growth of tobacco seedlings,but leaf-cutting could coordinate the proportion of roots and above ground parts of tobacco seedlings,could coordinate the ratio of height and stem girth of tobacco seedling.The leaf cutting of cigar,burley tobacco and flue-cured tobacco should be mastered flexibly according to the regularity,growth and transplanting plan of the tobacco seedlings.
