浅析海南地区石斛兰目标花期调控技术

Control technology of target flowering of Dendrobium in Hainan Province

石斛兰自然花期在8~11月,海南发展石斛兰具有得天独厚的自然优势,但是需对其自然花期进行调控以满足市场需求。通过研究在不同生长期施用不同营养配比的肥料调节石斛兰的生长状态,为调控目标花期打下基础,然后采取抹芽技术,确定好特定时期的抹芽与留芽工作,并采用升温或者降温的调控手段,实现目标花期开花的目的。结果表明,综合调控方法效果较好,石斛兰开花率达到85%。

The natural flowering period of Dendrobium is from August to November, Hainan has unique natu- ral advantages of developing Dendrobium but it＇s necessary to control the natural flowering period. In order to control the target flowering stage, the fertilization was controlled by applying fertilizer with different ratio of nutrients in different growth stages, and then wiping buds in particular period, and the temperature was raised or decreased to achieve the purpose of flowering in the target stage. The results showed that the comprehensive control method was effective and the flowering rate of Dendrobium was 85%.
