叶子花是应用较多的盆栽观花和园林绿化植物,在中国南北方都有广泛应用。通过花期调控技术研究,使叶子花能够周年开花,极大地扩展其应用范围,提高商品价值;另外花期调控技术还可以使育种者缩短叶子花育种周期,加快育种进程。在此,综述了叶子花花期技术,叶子花花芽分化进程受环境因子影响,通过光照、温度、水分的调控可达到控制花芽分化的目的;叶子花营养生长可通过栽培管理来调控,从而达到花期调控的目的;植物生长调节剂处理不仅能调控花期,还能延长开放时间,提高开花质量。对叶子花花期调控技术研究进展进行综述,从光照、温度、水分、栽培管理和生长调节剂等几方面的调控阐述叶子花花芽分化和花期调控技术研究现状,并提出了叶子花花期调控的综合技术措施。 Leaf flower is more applied potted flowers and landscaping plants, both in northern and southern China have a wide range of applications. Through the flowering control technology research, so that the flowering of the annual flower can greatly expand its scope of application and improve the value of the product; In addition flowering control technology can also make breeders to shorten the breeding cycle of leaf flowers and accelerate the breeding process. In this paper, the leaf flowering and flowering techniques are summarized. The flower bud differentiation process of leaves is influenced by environmental factors. The control of flower bud differentiation can be achieved through the regulation of light, temperature and water. The vegetative growth of leaf flowers can be regulated by cultivation and management to achieve flowering The purpose of regulation; plant growth regulator can not only regulate flowering, but also extend the opening hours and improve flowering quality. In this paper, the research progress on flowering regulation of leaf was reviewed. The research status of flowering bud differentiation and flowering regulation was discussed from the aspects of light, temperature, moisture, cultivation management and growth regulator. The synthesis of leaf flowering regulation Technical measures
