What to Do When Cattleya Flower Buds Dry Out
Cattleya flower bud drying is a common issue in cultivation, directly affecting the quality of flowering and ornamental value. This article systematically analyzes environmental control and nutrient supply techniques during the key stages from flower bud differentiation to full bloom, helping flower enthusiasts accurately grasp the essentials of care.
Three Key Elements of Environmental Control
Light Control Solutions
In winter, ensure 4 hours of direct sunlight daily, using a lux meter to monitor and ensure >3000LUX. In summer, use double-layer shading nets (60% light transmission rate) and set 2 hours of scattered light in the morning and evening. Special reminder: Sudden changes in light intensity during the flower bud differentiation stage can cause stress-induced drying.
Humidity Management Strategies
Use an ultrasonic humidifier to maintain humidity between 65%-75%, combined with a timed ventilation system. Spraying water on the leaves is recommended to be completed before 10 am, using a mist喷头 50cm away from the plant. Important data: When air humidity is below 50%, the survival rate of flower buds decreases by 40%.
Nutrient Supply System Construction
Fertilizer Ratio Solutions
During the flower bud stage, use a special fertilizer with N-P-K=3-9-6, controlling the EC value between 1.2-1.5mS/cm. Apply a combination of root irrigation and foliar spray every 10 days, with the addition of 0.1% boric acid solution to promote nutrient transport.
Key Points of Flower Promotion Techniques Using Temperature Difference
Day-Night Temperature Difference Control
Continuously maintain an effective temperature difference of 10-12°C, with 25°C during the day and 15°C at night being the best parameters. When using smart temperature control equipment, a 2-hour buffer transition period is required. Experimental data shows that when the temperature difference is <8°C, the flower bud drop rate increases by 35%.
Through systematic environmental control and precise care, the survival rate of Cattleya flower buds can be significantly improved to over 90%. It is recommended to adjust the care plan according to the specific condition of the plant, regularly check the breathability and pH of the planting material, and create ideal conditions for continuous flowering.
