Cultivation methods of orchid grass
As a traditional and precious ornamental plant, orchid grass is favored by gardening enthusiasts for its elegant leaf shape and quiet fragrance. However, in order to maintain healthy growth of orchid grass, professional cultivation techniques and scientific maintenance methods are needed. This article will systematically explain the five core points of orchid planting from soil ratio to four-season management. Scientific soil allocation plan for the basic elements of orchid cultivation The root system of orchid grass has extremely high requirements on the soil. It is recommended to use a golden ratio of 4:3:2:1: river sand (40%) ensures drainage, and humus soil (30%) provides organic matter., perlite (20%) enhances air permeability, and compost (10%) supplements nutrients. Adding pine bark particles when changing pots every year can adjust the pH value to the slightly acidic range of 5.5-6.5. Intelligent lighting control adopts the strategy of "shading in three seasons and full light in winter." Use a double-layer sunshade net to filter 60% of direct light in spring and summer, and reduce it to a single-layer sunshade in autumn. Direct light can be received before 9 o'clock in the morning and after 4 o'clock in the afternoon every day, and the scattered light intensity must be maintained between 8000-12000Lux during noon hours. The key points for environmental control of orchid grass are precise temperature management to build a "16-24℃ golden growth zone." In winter, the pot method (the outer flowerpot is filled with wood chips) is used to keep warm, and the bottom line of 10℃ is maintained with an electric heating hotbed. In summer, the substrate temperature is controlled below 28℃ through the ceramsite paving + atomization cooling system. Scientific supply of water implements the "see dry and wet" watering method, which is fully watered every 5 days in spring and summer, and extended to 7-10 days in autumn and winter. Adopt the immersion water supply method: place the flowerpot in a basin with a water depth of 2 cm and soak for 15 minutes, and use an electronic hygrometer to ensure that the substrate humidity is stable within the range of 40-60%. Nutritional cycle management During the growth season (March to October), special liquid fertilizer for orchids diluted 1000 times is applied every half month, and phosphorus and potassium fertilizers are added during the bud pregnancy period. During winter dormant period, leaf spraying of 0.1% potassium dihydrogen phosphate solution was used. Remember to carry out "backwater" washing within 12 hours after fertilization to avoid accumulation of fertilizer damage.
Through systematic environmental control and refined maintenance management, orchid grass can not only grow healthily, but also achieve continuous flowering year after year. It is recommended to regularly carry out daily care such as leaf wiping and root inspection, and flexibly adjust the maintenance plan based on seasonal changes, so that this oriental elegance can bloom in your home for a long time.
