花木无性繁殖,常因生根困难而影响成活。柳树枝条的浸出液能促进花木生根,提高成活率。具体方法如下: 1.扦插育苗 选用当年生的柳条,去掉叶片,剪成6～7cm长的小段,放在容器中(约一半露在外面)。加满水浸泡5～8天即成。把所需扦插的花木插穗基部放在浸出液中(深度约2cm),泡1天即可扦插。操作时,柳条浸出液宜随用随配;用浸出液处理过的插穗可提前5～10天生根。此法适用于桂花、石榴、栀子、夜来香、一品红等。
Asexual reproduction of flowers, often due to difficult rooting and survival. Willow branches of the leachate can promote the root of flowers and improve survival rate. The specific methods are as follows: 1. Cuttings Selection of the current year’s wicker, remove the leaves, cut into small pieces of 6 ~ 7cm long, placed in a container (about half exposed). Fill the water soak 5 to 8 days Serve. The cuttings required cuttings on the base of leaching solution (depth of about 2cm), soak for 1 day to cuttings. When operating, wicker leaching solution should be used along with; with leaching solution cuttings can be rooted 5 to 10 days in advance.
