| 摘 要： | 研究了不同扦插密度下连香树苗木的生根和生长发育状况,结果表明,随着扦插密度的增加,生根率、生根数、生根时间、最长根长、根系平均长度和根系发育状况均有明显的递减趋势。扦插密度愈小,苗木的整齐度、基径、分枝数、高径率、I级苗率等质量指标越好。经对不同扦插密度下苗木产量、质量和成本的综合分析,连香树苗木的适宜扦插密度为100～133株/m2。

| Abstract: | This paper studied the rooting rate,the root development situation,the growth character,the quality,the output and the production cost under the different cuttage density.The result indicated that with the increase of density,the rooting rate,root number and root development trend decrease significantly.The rooting rate reflects the most sensitive.The ratio of base diameter to high diameter is not obvious,and the height of seeding and branch numbering has no significant difference.With the increase of cutti... |
