Embodiment Construction
[0010] Comparative Experiment:
[0011] 500 pots of healthy longevity flowers were selected, and 400 pots of which were subjected to the florescence regulation treatment according to the method of the present invention during the flowering promotion period of the longevity flowers. The specific treatment method is: 8 hours of light period and 16 hours of dark period every day, and continuous treatment for 45 days. For example, when the flower urging starts in June, the blackout period is from 6 pm to 10 o'clock the next day, and the other time is the light period. During the light period, keep the light intensity between 10000 and 15000 lux. The plant height of the longevity flower affects its quality (too high a plant will result in a small number of florets, which cannot be clustered into clusters, which affects the ornamental nature, generally 25cm is the best height). Spraying butyryl hydrazide B9 when the flower buds begin to appear will shorten the length of the flower stem ...

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.
