How to Manage Cymbidium Flower Buds After They Appear
The bud development stage before the Cymbidium grandiflorum blooms is a crucial period that determines the quality of the flowers. At this time, the plant enters a vigorous reproductive growth phase and is more sensitive to elements such as light, water and fertilizer, and temperature. Mastering scientific management methods can not only extend the blooming period but also make the flowers more full and vibrant. This article will systematically analyze the refined cultivation techniques during the bud stage from five dimensions.
Light Control Strategies
Temperature Grading Management Method
When the ambient temperature is less than 25°C, ensure 4 hours of direct sunlight every day, with the best time being from 9-11 am and 3-5 pm. When the temperature is 25°C or higher, use double-layer shading nets to filter 50% of the light to prevent high-temperature strong light from burning the buds.
Nutrition Supply Plan
Phosphorus and Potassium Fertilizer Precise Ratio
Choose a water-soluble fertilizer with an N-P-K ratio of 1:3:2, and apply an 800-fold diluted solution every 10 days. It is highly recommended to add 0.1% potassium dihydrogen phosphate foliar fertilizer, which, when used in conjunction with root irrigation, can enhance the firmness of the buds.
Temperature and Humidity Dual Control System
Day and Night Temperature Difference Control
Maintain a daytime temperature of 18-22°C/nighttime temperature of 12-15°C, with a temperature difference of ≤8°C. When using intelligent temperature control equipment, avoid direct blowing of air conditioning and use a humidifier to maintain 60% air humidity.
Scientific Watering System
Substrate Dry and Wet Cycle Method
Use the "three-finger detection method": insert your fingers 3 cm deep into the substrate, and water thoroughly when it feels slightly moist. Use a long-spout pot to slowly pour water along the edge of the pot, avoiding water冲击 to the buds.
Water Spraying Avoidance Principle
Air atomizing water should be kept more than 50 cm away from the plant, focusing on the back of the leaves. Stop spraying water on the leaves 15 days before flowering and use a tray to increase humidity.
By implementing the four-dimensional cultivation system of "light grading-nutrition enhancement-temperature control balance-precise watering," the number of buds per branch can increase by 30%, and the blooming period can be extended by 10-15 days. Special attention should be paid to stop fertilizing after the color of the buds appears, maintaining a stable cultivation environment until full bloom.
