以4个苎麻品种为材料,研究了苎麻低位分枝扦插苗的插条长度与成苗率、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插条长度与单株叶干重、单株分枝数、最低分枝位、最高分枝位、分枝位长均呈极显著正相关,而与成苗率、单株根干重、主茎高度增加量均呈极显著负相关,但不同品种间有差异.综合考虑,苎麻低位分枝扦插苗的插条长度在5~10 cm较为理想.
Four ramie cultivars were used as materials to study the relationship between cutting length and seedling rate, root dry weight per plant, height increase of main stem, dry weight per plant and branch characteristics of ramie low branching cuttings. The results showed that the cuttings length of ramie low branches cutting seedlings had a very significant positive correlation with the dry weight of leaves, the number of branch, the lowest branch, the highest branch and the branch length, There was a significant negative correlation between the seedling rate, the root dry weight per plant and the increase of the main stem height, but there were differences among different cultivars.Accordingly, the cuttings length of ramie low branch cutting seedlings was better than 5 ~ 10 cm.
