| 摘要: |
| 比较不同基质、不同生根促进剂及其质量体积浓度、不同季节、不同修剪方式、不同插穗类
型对钟花樱（Cerasus campanulata）扦插生根的影响，结果表明：扦插基质类型、生根激素种类及其质量
体积浓度、扦插季节、插穗留叶面积以及插穗类型均对钟花樱扦插成活率和生根率产生显著或极显著影
响，扦插基质采用黄心土最有利于生根；生根激素种类及其各浓度处理效果均显著高于清水对照，其中
采用IBA 以质量体积浓度2 500 mg · L-1 速蘸10 s 处理效果最佳；于春季扦插最好；插穗留1 片或半片叶
片成活率及生根率远高于不留叶插穗；采用嫩枝扦插和带踵扦插优于硬枝扦插。因此钟花樱扦插宜在春
季，采用修剪成1 片或半片叶片带踵或嫩枝的插穗，经质量体积浓度2 500 mg · L-1 的 IBA 药液蘸10 s 后
扦插在黄心土上，生根效果最好。 |

| Abstract: |
| The effects of different cuttage matrix, different rooting promoter and its mass volume
concentration, different cutting season, different pruning methods and different types of cuttings on the rooting
of Cerasus campanulata were compared. The results showed that cuttage matrix, rooting hormone and its mass
volume concentration, cutting season, leaf area and type of cuttings had significant influence on the survival rate
and rooting rate of cuttings of C. campanulata. The best cuttage matrix was yellow soil, it was beneficial to the
root of the cuttings. The effect of rooting hormone and its mass volume concentration was significantly higher
than that of clear water, and the best effect was soak the cuttings in 2 500 mg · L-1 IBA solution 10 s. Spring is
the best cutting season. The survival rate and rooting rate of leaves with one or a half leaves were much higher
than those without leaf cuttings. Heel cutting and softwood cutting were better than hardwood cutting. The test
showsed that the cutting of C. campanulata in spring, using softwood cuttings or heel cuttings, each piece kept
total or half leaves, soak in 2 500 mg · L-1 IBA solution 10 s, then cutting in yellow soil, the rooting rate and
survival rate was the best. |
