以4个苎麻品种为材料,研究苎麻低位分枝扦插苗的扦插密度与成苗率、单株根干重、主茎高度增加量、单株叶干重及分枝特性的相关性.结果表明,苎麻低位分枝扦插苗的扦插密度与单株根干重、主茎高度增加量、单株叶干重、分枝位长之间呈极显著负相关,与单株平均分枝数、单株分枝干重之间呈显著负相关,与最低分枝位之间呈极显著正相关,不同品种间有差异.综合考虑,苎麻低位分枝扦插苗的扦插密度以10cm×10cm较为理想.

Four ramie varieties were selected as materials to investigate the correlation between cutting density of low branches and the following properties：survival rate,dry root weight,stem height recruitment,dry leaf weight and branch characteristics.Significant negative correlation could be observed between cutting density and dry root weight,stem height recruitment,dry leaf weight,branch length.Negative correlation could be observed between cutting density and quantities of branches,dry branche weight.And a significant positive correlation existed...
