The Method of Hydroponic Cultivation of Orchids and Precautions
Hydroponic orchids, with their clean and elegant appearance and visible root systems, are becoming a new favorite among indoor green plants. Compared to traditional soil cultivation, hydroponic orchids allow for a more intuitive observation of the plant's condition, but special care techniques need to be mastered. This article will systematically analyze the six core operational steps of hydroponic orchid cultivation and extend to discuss advanced care tips to help you successfully create the beauty of orchid elegance blooming in water.
Basic Preparation for Hydroponic Orchid Cultivation
Selection Criteria for Special Containers
The double-layer pot structure is the key to success. It is recommended to choose a container made of ABS material with an inner mesh aperture of 3-5mm, and the outer liquid storage layer must be at least 8cm deep. When configuring ceramsite, select porous lightweight particles with a diameter of 1-2cm, which can both stabilize the plant and facilitate oxygen exchange.
Plant Pretreatment Process
After potting, retain 3-5 main roots and leave a 2cm stub when cutting off the weak roots. Soak in a 50% carbendazim solution diluted 800 times for 15 minutes, focusing on the incision area, and after disinfection, rinse with running water for 30 minutes to completely remove any medication residue.
Practical Operation of Building a Hydroponic System
Scientific Planting Techniques
The Method of Hydroponic Cultivation of Orchids and Precautions
Spread the roots in an umbrella shape through the sieve holes, with the base of the bulb 1-2cm away from the liquid surface. Use the cross fixation method: first lay a 2cm layer of ceramsite, then place the plant and add the medium in three layers, lifting the plant slightly after each layer to ensure it stands upright.
Norms for Nutrient Solution Preparation
Use a root-promoting nutrient solution with an EC value of 0.8ms/cm during the initial planting stage, adjusting the nitrogen-phosphorus-potassium ratio to 1:2:2. It is recommended to use a special hydroponic nutrient agent for orchids and supplement with 3ml of chelated iron each month to prevent yellowing leaves.
Hydroponic Orchid Care System
Water Quality Management Points
Use rainwater or purified water preferably, and if using tap water, let it sit for 48 hours. Replace the nutrient solution every 5 days in summer and every 10 days in winter, retaining 1/3 of the original solution each time to maintain bacterial balance.
Environmental Control Strategies
Keep the water temperature between 18-25°C and control the light intensity between 8000-12000Lux. Set up a circulating aeration system, running for 2 hours daily to promote root respiration, and maintain humidity between 60-70%.
Through scientific hydroponic system setup and meticulous care, orchids can develop unique hydroponic root systems. Regularly observe the growth of the root tip transparent crystal head and supplement trace elements as needed. Mastering the liquid replacement cycle and environmental balance, hydroponic orchids can also display an elegant posture, creating a unique indoor water景 ecosystem.
