How can an orchid grow roots and sprout?
As a famous traditional flower in China, orchids are deeply loved by flower friends for their elegant attitude. For orchids to grow healthily and germinate new buds, scientific conservation methods are needed. This article will systematically analyze the key technologies for orchid rooting and germination from plant material formulation to environmental control. 1. Core points of orchid root cultivation 1. The golden rule for plant preparation Ideal orchid plant materials must have three major characteristics: ventilation, water retention and nutrition. It is recommended to adopt a three-level layered structure: 3-5cm pine bark (diameter 2-3cm) is used as the drainage layer on the bottom layer, decomposed pine needles (40%), volcanic rock (30%), and coconut shells (20%) are mixed in the middle layer, and 1 cm of moss is spread on the surface layer to moisturize. This structure increases the air circulation at the root contact surface by 40%, effectively preventing root rot. 2. The precise environmental control strategy stabilizes the environmental temperature within the range of 18-24℃, and controls the temperature difference between day and night within 5℃. Use a sunscreen net with a 60% blocking rate to ensure that light is scattered for 3 hours a day. The air humidity is maintained at 65%-75%, and can be sprayed for 15 minutes in the morning and evening every day through an atomizing humidifier. Pay special attention to keeping the basin spacing more than 20cm to ensure air circulation. 2. Comprehensive strategy for promoting and maintaining new shoots 1. During the critical period of nutrient supply, the principle of "thin fertilizer and frequent application" is adopted during the germination period of new shoots (March to May). Apply orchid special fertilizer (N-P-K=30-10-10) diluted 2000 times every week, and use seaweed essence once a month for root irrigation. Rinse the leaf cores with clear water within 6 hours after fertilization to avoid fertilizer damage. When the new buds grow to 5cm, use balanced fertilizer (20-20-20) to promote healthy growth. 2. Attention should be paid to the protection points during the special stage when new buds break ground: ① Avoid direct light burns and use a double sunshade net;② Keep the substrate moist without water;③ Environmental temperature fluctuations should not exceed 3℃/day;④ Use azadirachin 1000 times solution to prevent and control aphids when discovered. After mature buds expand their leaves, the light can be gradually increased to 5 hours a day.
Through scientific plant material ratio and environmental control, coupled with precise fertilizer and water management, the growth rate of orchid roots can be increased by more than 50%. It is recommended to change the pot every two years in the spring, prune the old roots and update the planting materials. Mastering these core skills, even novices can let orchids sprout new shoots every year and bloom gracefully.
