樱花是蔷薇科樱属的落叶乔木,树形秀美,叶深绿色,互生,花有红色、粉色及玫瑰色,3—5朵组成伞房花序,极其美丽,华北地区于3月末4月初盛开,与叶同放,满树烂漫,如云如霞,是早春开花的著名观赏花木,且果仁可入药。但是樱花的繁殖还是用嫁接的方法,用毛樱桃、毛桃种子播种育苗作砧木,嫁接技术较复杂,且育苗周期长,偶见有材料介绍樱花的无性繁殖方法,成活率也只达60%左右。为探索樱花无性繁殖的方法及提高其生根率的途径,我们做了一系列樱花嫩枝扦插的试验,生根率达95%以上,现将具体方法介绍如下。
Cherry is a deciduous tree of the genus Rosaceae, beautiful in tree shape, dark green leaves, alternate flowers with red, pink and rose, composed of 3-5 coryntilles, extremely beautiful, in northern China in early March early April bloom in early April, With the leaves with the release, full of trees, such as Yun Ru Xia, is a famous early spring flowering flowers, and nuts can be used as medicine. However, the breeding of cherry or grafting method, the use of cherry, peach seed sowing seedlings as a rootstock, grafting technology is more complex, and the breeding cycle is long, and occasionally introduced cherry material asexual reproduction method, the survival rate of only about 60% . In order to explore the method of asexual reproduction of cherry and the way to improve its rooting rate, we made a series of experiments on the shoot cutting of cherry. The rooting rate reached more than 95%. The specific methods are introduced as follows.
