What type of planting material is used for Huilan Day一品
As a representative variety of the traditional Chinese orchid, Jiuhua Orchid, Huilan Day一品 is highly favored for its upright flower posture and elegant fragrance. To cultivate healthy and blooming Huilan Day一品, one must master three key maintenance techniques: scientific soil mixing, precise flowering promotion, and meticulous management. This article will systematically analyze from planting material formulas to daily maintenance, helping you easily cultivate premium orchids that bloom year after year.
Ⅰ. Core Planting Material Formula Analysis
1.1 Selection of Breathable Substrate
Huilan's fleshy roots have a high demand for oxygen, and it is recommended to use pine bark with a diameter of 0.5-1.5cm as the main material. Its natural porous structure can form a microcirculation system. Combine volcanic rock particles (3-5mm) to enhance support, keeping the porosity of the planting material between 35%-40%.
1.2 Water-retaining Material Proportions
Add 10%-15% sphagnum moss to adjust humidity, which can be increased to 20% in spring and summer. Mix decomposed oak leaves (≤8% proportion) to provide slow-release nutrients, noting that they need to be steam-sterilized at high temperatures to avoid residual eggs.
1.3 Drainage System Optimization
Use a double-layer pot structure: the inner pot bottom is laid with a 3cm thick layer of ceramsite, and the outer pot is set with a water guide groove. It is recommended that the total height of the planting material layer does not exceed 2/3 of the pot, leaving space for air circulation.
Ⅱ. Precise Flower Promotion Management Plan
2.1 Light Cycle Regulation
During the flower bud differentiation period (September-October), ensure 4 hours of direct morning light per day, with light intensity controlled between 8000-12000Lux. Use shade nets to adjust and avoid scorching the leaves with strong midday sunlight.
2.2 Temperature Difference Stimulation Techniques
Maintain a day-night temperature difference of 8-10°C in autumn, with the night temperature lowered to 15°C for 20 consecutive days, which can effectively activate flower bud development. Combine with foliar application of potassium dihydrogen phosphate (1500 times liquid), once every 10 days.
Ⅲ. Daily Maintenance Detail Control
3.1 Intelligent Watering Strategy
Use the "three-finger test method": insert the fingers 3cm deep into the planting material, and it is slightly moist. Spray to increase humidity in the morning and evening in summer, maintaining air humidity at 60%-70%, and control water to once every half month in winter.
3.2 Potting Operation Standards
Change pots every spring, retaining 1/3 of the heart soil. After pruning the roots, soak them in carbendazim (800 times liquid) for 20 minutes, then dry the roots for 12 hours before potting. The diameter of the new pot should be 3-5cm larger than the original pot.
By ensuring root health through scientific soil mixing, precisely controlling light, water, and fertilizer to promote flower bud differentiation, and combining standardized maintenance processes, Huilan Day一品 can achieve an average annual blooming of 2-3 arrows, with up to 9-12 flowers per arrow. Mastering these core techniques, even beginners can cultivate premium orchids with fragrant and elegant postures.
