扦插繁殖对快速培育园林树木具有重要作用,它的好处有: 1.解决重瓣花不结实的繁殖间题。如白玫瑰、木槿等。 2.容易选择雌雄株。城市绿化对树木雌雄的选择比较严格。如杨柳类则要求用雄株。因为雌株在5—6月飞絮时形成“六月雪”,这对城市人民及精密仪器工厂都会造成麻烦。若选用雄株则无此虑。 3.保持花色品种纯正。例如紫薇等花色复杂的树种,为了分别培育红花和白花品种,则以扦插为最准确。 4.补救种子缺少时的繁殖。如雪松、玉兰
Cutting propagation on the rapid cultivation of garden trees has an important role, its benefits are: 1. Solve the heavy petal flowers not reproductive problems. Such as white roses, hibiscus and so on. 2. easy to choose male and female strains. Urban afforestation on the male and female trees more stringent choice. If the willow class requires male plants. Because the female plant formed “June Snow” when flying from May to June, this caused troubles to both urban people and precision instrument factories. If the choice of male plant is no such concern. 3. Maintain the color variety pure. For example, crape myrtle and other complex color species, in order to cultivate safflower and white flower varieties, the cutting is the most accurate. 4. Reproduce the seed when the seed is missing. Such as cedar, magnolia
