Hydroponic Cultivation Methods and Precautions for巴西木
Hydroponic巴西木, with its unique shape and air purification ability, has become a popular indoor landscape for city dwellers. However, many beginners find that the plants exhibit yellowing leaves and curly branches. How to ensure the healthy growth of this tropical plant in a hydroponic environment? Mastering the following core maintenance techniques is crucial.
Key Points for Setting Up a Hydroponic System
Container Selection and Water Quality Management
It is recommended to use a transparent glass container with a diameter of more than 15cm, and the mouth of the bottle needs to support the weight of the plant. For the initial hydroponic setup, mineral water is suggested, with a pH value controlled between 5.5-6.5. Water change frequency should be every 3 days initially, then extended to every 7 days once stable, retaining 1/3 of the original water to maintain microbial balance.
Nutrition Supplement Plan
Add hydroponic-specific nutrient solution twice a month, focusing on supplementing calcium nitrate (concentration 0.1%) and chelated iron. During the high-temperature summer, amino acid-based liquid fertilizers can be increased, diluted at a ratio of 1:1000 before use to avoid direct contact with aerial roots.
Key Aspects of Daily Maintenance
Light Control Techniques
Set up 4 hours of scattered light daily, which can be placed 1.5 meters away from an east-facing window. Use a shade cloth with 30% light blocking to filter strong light and avoid direct midday sunlight. In winter, supplement with LED plant growth lights, maintaining a light intensity of 8000-10000 lux.
Shaping and Pruning Methods
Hydroponic Cultivation Methods and Precautions for巴西木
During the growing season, prune once a month, retaining 3-4 growth nodes on the main stem. Use pruning shears sanitized with alcohol, and apply charcoal powder to the cut surface to prevent infection. Avoid changing water within 2 days after pruning, allowing the cut surface to form callus.
Strategies for Dealing with Common Issues
Yellow Leaf Treatment
Basal yellowing of two-year-old plants is a normal metabolic process and should be removed promptly. If new leaves turn yellow, check for iron deficiency (yellowing between veins) or root rot (accompanied by a water odor). If root rot is found, switch to a ceramsite substrate immediately and soak with a 0.05% potassium permanganate solution.
Key Points for Overwintering Management
Keep the water temperature above 18℃, using a constant temperature mat to maintain root temperature. When the air humidity is below 40%, spray daily to increase humidity, avoiding the low-temperature period at night. Stop adding nutrient solution and switch to clear water maintenance.
By scientifically managing water quality, precisely supplying nutrients, and timely pruning maintenance, hydroponic巴西木 can remain green all year round. It is recommended to record plant growth data monthly and adjust the maintenance plan according to seasonal changes to keep this tropical plant in the best condition in an indoor environment.
