How to promote orchid germination in spring
Early spring is the critical period for orchids to sprout, and reasonable management measures can effectively improve the germination rate of new buds. Mastering the synergistic effect of the three factors of temperature, nutrients and humidity, combined with scientific maintenance methods, can allow the orchid plants to show vigorous growth of "one mother with three buds." This article systematically analyzes the four core maintenance technologies to help you cultivate strong and plump orchids. Nutrient regulation and management plant renewal strategy selects a mixed substrate of pine bark (40%), volcanic rock (30%), phytolite (20%), and decomposed peanut shells (10%), which is replaced every two years. When changing pots in spring, keep 1/3 of the heart soil, cut off the rotten roots and apply charcoal powder for disinfection. The precise fertilization plan applies water-soluble fertilizer with N-P-K=20-10-10 (diluted 1500 times) in the early stage of germination, and irrigates it every 15 days. After the new buds germinate, use balanced fertilizer (15-15-15), combined with foliar spraying potassium dihydrogen phosphate (2000 times solution). Rope propagation technology When the orchid bush reaches more than 6 seedlings, select sunny and warm weather for rationing. After disinfecting the knife with alcohol, divide it along the gap between the false bulbs to ensure that more than 3 seedlings are retained in each clump. After dividing, place the plants in a scattered light place for maintenance, and avoid watering for 7 days. Growth regulation uses a 30mg/L 6-BA cytokinin solution, spot coating treatment on the base of pseudobulbs, once every 10 days, twice in a row. During the treatment period, the daily temperature was maintained at 25℃/night temperature was 18℃, and the air humidity was above 70%. Scientific management of the flowering period immediately after the flowers die, cut off the scape and retain 2cm of stems to prevent infection. After pruning, EM bacterial organic fertilizer (mixed with water at 1:50) was added, and 2 hours of morning light irradiation was added to promote the accumulation of photosynthetics.
Through the above-mentioned four-dimensional sprouting promotion system, the germination rate of orchids can be increased by more than 60%. The key is to grasp the "three timely" principles: timely change of pots to replenish substrate fertility, timely rationing to optimize growth space, and timely pruning to regulate nutrient distribution. Combined with fine management of temperature and humidity, the orchid plants will surely burst into vitality in spring.
