Maintenance of crab claw orchid during flowering period
As a star flower in winter and spring, the brilliant bloom of Crabclaw Orchid is always something to look forward to. However, many flower lovers have found that carefully maintained crabclaw orchids often have problems such as falling buds and dull colors during the flowering period. This article will analyze how to make Crabclaw Orchid bloom more lasting through four key maintenance dimensions and combined with the physiological characteristics of flowering period. 1. Scientific moisture management 1.1 It is recommended to use the "three-finger detection method" to accurately judge watering timing: insert the index finger, middle finger and ring finger side by side into the substrate to a depth of 2cm. When the fingertips touch the touch slightly cool but no soil particles are adhered to, you can replenish water. Keep the substrate humidity in the range of 40-60% during flowering, and use bamboo sticks to assist detection is more accurate. 1.2 Intelligent water replenishment plan The northern heating environment uses atomizing humidifiers to maintain 50% air humidity; the southern humid areas use ceramite pads to isolate excess moisture. It is recommended to carry out bottom dipping in the basin from 9 to 10 o'clock in the morning, and the amount of water supplied at a single time should not exceed 1/5 of the volume of the basin. 2. Regulation of the nutritional cycle 2.1 Judgment during the critical period of stopping fertilization. Stop fertilization immediately when the flower buds complete coloring (that is, obvious color colors can be seen at the top). It is recommended to use an EC value testing pen. When the EC value of the substrate is greater than 1.2mS/cm, the nutrient supply should be suspended. 2.2 If the development of flower buds is delayed in the emergency fertilizer supplement plan, 50ppm potassium dihydrogen phosphate solution can be sprayed on the leaves (once a week for 2 consecutive weeks), paying attention to avoid the high temperature period at noon. 3. Optimization of the light environment 3.1 Dynamic light adjustment ensures 4-6 hours of scattered light every day during the flowering period, and uses an illuminance meter to monitor and maintain a light intensity of 15,000 - 25,000 lux. Turn the flowerpot 15 degrees every 2 hours to ensure that the corolla receives even light. 3.2 Manual filling light guide When it is continuously rainy and rainy, use a full-spectrum plant fill light and set the daily filling light for 3 hours (1.5 hours each at 10 a.m. and 2 p.m.), with a distance of 40cm from the plant. 4. Create a micro-environment 4.1 The intelligent ventilation system is equipped with a temperature and humidity linkage ventilation device, which automatically starts the circulation fan when the temperature is>18℃ and the humidity is>65%. The natural ventilation period is selected from 10-11 a.m., and the window opening angle is 30 degrees to avoid strong convection. 4.2 Pest and insect pest prevention Use garlic extract (1:50) spray every week to prevent diseases. Aphids found immediately use a cotton swab dipped in 75% alcohol and treat them locally. Maintaining the temperature difference between day and night at 6-8℃ can enhance plant resistance.
Through refined management of the above four dimensions, the flowering period of Crabclaw Orchid can be extended to 3-4 months. The key is to grasp the "three harmonizations" principle: coordination between moisture and light, coordination between nutrition and growth stages, and coordination between temperature and ventilation. It is recommended to establish a maintenance log to record daily environmental parameters and gradually form a personalized maintenance plan.
