| 摘要: |
| 半枫荷（Semiliquidambar cathayensis）是中国特有树种，为总结半枫荷扦插育苗技术，采用
L9(34) 正交试验设计的方法研究了插穗来源及生根剂的选取对半枫荷扦插成活率的影响，并通过验证试
验探讨了不同基质处理下半枫荷的扦插生根情况。研究结果表明，插穗来源、生根剂种类、生根剂浓度
和生根剂的处理时间都极显著影响着半枫荷的扦插成活率，且这 4 个因素对半枫荷扦插生根的影响排序
为：插穗来源（A）＞生根剂种类（B）＞生根剂处理时间（D）＞生根剂浓度（C）。半枫荷插穗选择最
优方案为：从半枫荷大树的树冠基部采集当年萌生的半木质化枝条制成长 8 cm、直径 0.5 cm 左右的插
穗，经浓度为 500 mg · L-1 的 ABT 溶液处理 1 000 s，在泥炭土中进行扦插育苗，可取得 82.22% 的扦插成
活率，且平均生根数可达 9.06 条，平均根长可达 12.58 cm。 |

| Abstract: |
| Semiliquidambar cathayensis is an endemic tree species in China. To summarize its cutting
seedling technology, L9(34
) orthogonal experiment was used to study the effect of cutting source and rooting agent
on the survival rate of cuttings, and discussed the cutting rooting under different substrate treatments by Validation
test.The results showed that the source of cuttings, the type of rooting agent, the concentration of rooting agent,
and the treatment time of rooting agent all significantly affected the survival rate of the cuttings of S. cathayensis.
They were followed as: the source of cuttings (A)> types of rooting agent (B)> treatment time of rooting agent
(D)> concentration of rooting agent (C). The optimal choice is: collecting half-lignified branches germinated that
year from the base of the crown of the big maple lotus tree to make cuttings with a length of 8 cm and a diameter
of about 0.5 cm, and an ABT solution with a concentration of 500 mg · L-1 after 1 000 s of treatment, when cutting
in peat soil, the cutting survival rate can achieve 82.22%, and the average number of roots can reach 9.06, the
average root length can reach 12.58 cm. |
