春季是绝大部分花木进行扦插繁殖的最佳季节。适于春季扦插繁殖的花木有两大类:一类是生根时间长、不易生根的灌木和常绿树,如雪松、龙柏、真柏、圆柏、撒金柏、铺地柏、法桐等;另一类是易生根的花木,如石榴、月季、木槿、迎春、紫薇、翠柏、蜀桧、凌霄、金银花、郁李、爬墙虎、扶芳藤、红背桂、佛手、鹅掌杜鹃、紫叶小檗、珠兰、茉莉、银杏、垂柳等。这两类花木采用春插,一般成活率可达85％-95％。观赏花木春插植物的标准是:树液开始流动,枝条刚开始萌发,但尚未发芽,通常为3月初至4月中旬,过早或过迟均不利于成活。其具体方法如下:
Spring is the best season for cuttage propagation of most flowers and trees. Suitable for spring cutting propagation of flowers there are two categories: one is rooting for a long time, not easy to root shrubs and evergreen trees, such as cedar, cypress, true cypress, Sabina, Cassia, Cypress, Etc .; the other is easy to root the flowers, such as pomegranate, rose, hibiscus, spring, crape myrtle, cypress, Shu cypress, Peak, honeysuckle, Yu Li, climbing wall tiger, Euonymus fortunei, red back Gui, bergamot, Goosefoot rhododendron, purple leaf berberine, blueberry, jasmine, ginkgo, weeping willow and so on. These two types of flowers using spring insert, the general survival rate of up to 85% -95%. The standard for ornamental plants is that the sap begins to flow and the shoots begin to germinate but not yet germinate, usually from early March to mid-April, premature or too late are not conducive to survival. The specific method is as follows:
