Embodiment Construction

[0010] Comparative Experiment:

[0011] Select 500 pots of healthy Longevity Flowers, and 400 pots of them carry out florescence regulation and treatment according to the method of the present invention during the flowering promotion period of Longevity Flowers. The specific treatment method is as follows: 8 hours of light period and 16 hours of dark period are given every day, and the treatment is continued for 45 days. For example, starting to promote flowering in June, the period from 6:00 pm to 10:00 the next day is the total blackout period, and the rest of the time is the light period. During the light period, keep the light intensity between 10,000 and 15,000 lux. The plant height of Changshouhua affects its quality (too high a plant will lead to a small number of florets, which cannot be clustered together and affect the ornamental value. Generally, 25CM is the best height). Spraying Dinazide B9 at the beginning of flower bud emergence, if applied too late, will short...

Abstract

The invention belongs to the plant cultivation technical field. A jonquil florescence control method is characterized in that the beginning of the 40-45 days before flowering expectation is taken as the flower promoting period which has 8-hour illumination per day and 16-hour short-day treatment in the darkness for uninterrupted 45 days; the illumination intensity of the illumination time is within 10000-15000lux; at the beginning of flower bud appearance, daminozide B9 is used, and the best application concentration is 2500-5000mg / L; when the lateral branches start growing, or after 20-30 days of short-day illumination treatment, ancymidol is sprayed; after one month of short-day illumination treatment, ethephon with a concentration of 250-500mg / L is sprayed twice, once per week.
