Cymbidium blooms several times a year
As a high-profile variety in the orchid family, Cymbidium has become a frequent visitor on the maintenance list of many flower lovers due to its elegant flower appearance and long-lasting blooming characteristics. Its unique flowering characteristics and maintenance needs deserve an in-depth understanding of every grower. Natural flowering characteristics of Cymbidium hybridum, which is native to subtropical areas, follows the natural flowering cycle from October to April of the following year. A single healthy plant can usually maintain an ornamental period of 20-30 days, and the lipped flowers bloom one after another on the spike, creating an amazing visual effect. Studies on the biological characteristics of single-season flowering and plant physiology have shown that Cymbidium hybridum belongs to a typical orchid plant that opens once a year. Its flower bud differentiation requires a complete nutrient accumulation period. In an artificial cultivation environment, about 97% of the plants maintain the rule of single flowering every year. The golden rule of light management in Cymbidium multi-flower cultivation system 5-6 hours of scattered light irradiation every day is the key to promoting the development of multi-flower. Full sunshine can be accepted in spring and winter, and 50% sunshade net protection is needed in summer to avoid strong light burning false bulbs. It is recommended to use a illuminance meter to monitor and maintain the light intensity of 20,000 - 30,000 Lux. The key points of collaborative management of water and fertilizer adopt the watering principle of "seeing dry, seeing wet", and the moisture content of the substrate is controlled within the range of 40-60%. Topdressing application of a high-phosphorus special fertilizer for multi-flowering with NPK=10:30:20 after flowering, combined with foliar spraying of 3000 times seaweed once a week, can significantly improve the flower bud differentiation rate. Temperature and humidity are accurately controlled to maintain 25-28 ° C during the day, and the temperature difference of cooling to 15-18 ° C at night is stimulated. With an air humidity of 60-70%, it can simulate native climate conditions. It is recommended to configure a temperature and humidity recorder for data tracking. Technical specifications for post-flowering pruning. Immediately after the flowers wither, cut off the base of the pedicel more than 3 cm, and at the same time remove the withered leaves. Use special blue scissors disinfected by alcohol and apply charcoal powder to the incision to prevent infection. Practice of continuous flowering of Cymbidium Through a three-year comparative experiment, it was found that the secondary flowering rate of plants using the compound maintenance method could reach 38%. The key point is to establish an annual maintenance calendar: pruning roots and replacing pots in March, controlling water to promote flowers in June, and replenishing light to promote buds in September, forming a complete growth cycle management chain.
To achieve sustainable flowering of Cymbidium, it is necessary to systematically integrate factors such as light, temperature, humidity, water and fertilizer. Although the probability of blooming is restricted by multiple factors, through scientific and refined management, it is entirely possible to break through its natural growth laws and create a surprising miracle of blooming.
