When does Phalaenopsis bloom?
Known as the "Queen of Orchid", the Phalaenopsis orchid has always attracted the attention of flower growers with its elegant flower appearance and unique flowering period. As a typical New Year flower, it not only carries the blessings of the New Year, but also becomes the focus of modern horticulture research due to its flowering control technology. This article will deeply analyze the natural flowering rules and manual intervention skills of Phalaenopsis. Natural flowering season characteristics of Phalaenopsis The biological characteristics of winter-spring blooming Phalaenopsis is native to the tropical rainforest, and has evolved into the characteristics of winter-spring blooming after a long period of time. Its flower bud differentiation requires a temperature difference of 15-28℃, and most bloom naturally from November to March of the following year. The inflorescences emerge from leaf axils, and each branch can open 8-15 butterfly-shaped flowers. The full flowering period can last for 2-3 months. Conditions for achieving dual flowering periods Professional orchid gardens can cultivate secondary flowering through post-flowering pruning: retaining 3-4 flower stems, combined with constant temperature of 20 ° C and light of 20000lux, flower buds can be reproduced after 60 days. Family maintenance requires attention to cutting off residual flowers in a timely manner to avoid nutrient consumption. Modern flowering control core technology temperature control three-stage management 1. Flowering promotion stage: Maintain 18-25℃ to promote flower bud differentiation 2. Color development stage: Reduce to 15-20℃ to deepen the color 3. Flowering stage: Maintain 12-15℃ to prolong the flowering period, and accurately control water and fertilizer. Use LED filling light system to provide 12 hours of light intensity of 2000-3000fc every day. Combined with a special nutrient solution with an EC value of 1.2-1.5ms/cm, spraying phosphorus and potassium fertilizers every 7 days can shorten the flowering regulation period by 30%. Key points for home maintenance The golden rule of water management During flowering, keep the substrate slightly moist (water content 40%), use immersion basin method for water supply, and the water temperature needs to be consistent with room temperature. Control the air humidity at 60-70% to avoid water droplets staying on petals and causing brown spots. Collaborative control of environmental factors maintains a temperature difference of 5-8℃ during day and night, and no lower than 15℃ at night. Strengthen ventilation and maintain CO ˇ concentration at 800-1000ppm to enhance plant stress resistance. Rotate the flowerpot regularly to ensure uniform light reception.
Mastering the phenological laws of Phalaenopsis and combining them with modern environmental control technology can not only appreciate the beauty of its natural flowering period, but also realize the anniversary flower supply. Whether it is professional production or home viewing, only by understanding and respecting its growth characteristics can we make this "flying flower" bloom in the most touching manner.
