Abstract

The invention discloses a flowering time regulation method of yellow heliconia bihai. Lighting supplement is started 70 days before expected flowering; lighting is carried out and lasts for 14 hours per day; full sun is provided from 8:00 to 18:00 every day; intermittent lighting supplement is carried out from 18:00 to 0:00 of the next day, wherein lighting is carried out every two hours and lasts for two hours, and namely four hours of lighting is added; complete shielding is carried out during other time frames, the illumination intensity is kept between 12000Lx and 18000Lx during the lighting period, and lighting supplement is stopped 30 days before flowering; 600-fold peters professional 12 is applied once every four days, wherein 600 fold means the weight / volume ratio is 600; the temperature of cultivation conditions is kept between 20DEG C and 26DEG C in daylight and is kept between 16DEG C and 18DEG C at night, and the humidity is kept between 70% and 80%. Due to the adoption of the flowering time regulation method, the yellow heliconia bihai flowers early, the flowering time is more than 30 days longer than that of traditional cultivation, plants are compact, and flowers are tidy and colorful and have good ornamental value during the full-bloom stage.
