龙爪槐是国槐的芽变品种,落叶乔木、喜光、稍耐阴、能适应干冷气候。树冠如伞,上部蟠曲如龙,形态优美,叶、花供观赏,是优良的园林树种,现代城市绿化中较为广泛利用,但其嫁接不到位,易偏冠或易折断。通过多年的生产实践总结,应从砧木的选取、接穗的选择、枝条的采集处理、嫁接时间,嫁接后的抹芽、解绑、接点固定及病虫防治等多方面技术保证,才能嫁接成功。 Longhuhuai Sophora japonica is a variety of buds, deciduous tree, hi light, slightly shade-tolerant, able to adapt to dry and cold climate.
