How long can an orchid bud bloom?
Watching orchids draw out delicate buds but fail to bloom, many orchid farmers have experienced this sweet suffering. As one of the top ten famous flowers in China, orchid has a hidden mystery in its bud development process, and the flowering cycles of different varieties differ greatly. Only by mastering the growth laws of flower buds can this "beautiful lady in the empty valley" exude fragrance as scheduled. The breeding period of bud fully reveals the differences in varieties and determines the period. The sister flowers of Jianlan and Chunlan best reflect the time difference: the former only takes more than half a month from bud to full bloom, while the latter has to undergo a long wait of 5-6 months. The buds of varieties that bloom in winter and spring such as Moran and Hanlan quietly form in summer. Environmental factors affect the development rate of flower buds by 30% when the temperature difference between day and night reaches 8-10℃. Controlling humidity within the range of 60-70%, combined with scattered light irradiation, can effectively promote nutrient accumulation. It is worth noting that the maturity of annual false bulbs directly determines the quality of flowering. Response plan for bud stagnation vernalization wake-up mechanism Spring orchids, cymbids, etc. need to undergo 30 days of low temperature vernalization of around 10℃. Refrigerator refrigeration can be used: Wrap the slightly dried flower plants in newspaper, place them in a fresh layer of fruits and vegetables, and check the humidity every 3 days. This method is especially suitable for orchids in heating rooms in the north. Water control art watering during the bud period requires immersion: pour the plant material thoroughly and drain it to keep the substrate in a "moist but not wet" state. The air humidity can be maintained at 65% with a humidifier. Never spray water directly on the buds to avoid causing "stiff buds." Nutrient replenishment strategy Phosphorus and potassium fertilizers can be top-applied in the early stage of budding, and it is recommended to use 0.1% potassium dihydrogen phosphate solution for foliar spraying. Stop applying fertilizer when the flower arrow stretches to 3 cm. At this time, excessive nutrition will lead to the extinction of the bud. A small amount of boron can be added to promote flower development.
Patience is a required course for people who raise orchids. By observing the color changes of the flower buds (turning green to white indicates that they are about to open) and cooperating with scientific maintenance techniques, the room will surely be filled with fragrance. Remember that each orchid has its own life rhythm, and waiting for the flowers to bloom is the highest level.
