How to Make Ch君子兰花 Produce Side Shoots
As a foliage plant beloved by flower enthusiasts, the development of side shoots in Ch君子兰花 directly affects the beauty of its shape. Many orchid friends often face the problem of plants not producing side shoots, but actually, improving the details of care can effectively activate the plant's growth potential. This article will systematically analyze practical techniques to promote the germination of side shoots in Ch君子lan from soil improvement to environmental regulation.
1. Substrate Improvement Plan
1.1 Soil Proportion Optimization
The root system of Ch君子lan requires up to 70% humus, it is recommended to use the golden ratio of pine needle soil: decomposed leaf soil: river sand = 5:3:2. Add bone meal as a base fertilizer when repotting every spring to maintain a slightly acidic soil (pH 5.5-6.5).
1.2 Key Points for Repotting
Choose a ceramic pot 5cm larger than the original one, retaining 1/3 of the heart-protecting soil. After repotting, place it in a scattered light area for 7 days to slow down the seedlings, keeping the substrate moist but not waterlogged during this period.
2. Temperature and Light Synergy Management
2.1 Precise Temperature Control
Maintain a day-night temperature difference of 8-10℃ (day 22℃/night 14℃), and no lower than 10℃ in winter. Outdoor maintenance can be done in spring and autumn, while shade nets are needed in summer to reduce the ambient temperature by 3-5℃.
2.2 Light Cycle Setting
Ensure 4 hours of direct sunlight plus 6 hours of scattered light daily, and use a 40% light-blocking curtain to filter strong light. Regularly rotate the pot to ensure even light exposure.
3. Nutrition Supplement Strategy
3.1 Fertilizer Ratio Plan
Apply a balanced fertilizer (15-15-15) every half month during the growing period, and increase the application of phosphorus and potassium fertilizers during the shooting period. It is recommended to use a diluted 1000-fold orchid-specific nutrient solution.
3.2 Fertilization Operation Norms
Apply fertilizer in a circular trench along the edge of the pot, with a depth of 3-5cm. After fertilizing, loosen the soil to promote nutrient penetration. Stop fertilizing during the high summer temperatures and flowering period.
4. Environmental Optimization Measures
4.1 Ventilation System Setup
Install a circulation fan to run for 2-3 hours daily, maintaining an air flow rate of 0.3-0.5m/s. During the rainy season, use a dehumidifier to maintain a humidity of 50-60%.
4.2 Space Layout Adjustment
Keep a plant spacing of more than 30cm, and regularly prune the lower old leaves. Use bamboo stakes to improve the light absorption angle of the leaves.
Through the above systematic care plan, visible side shoots can be seen within 60-90 days. The key is to grasp the three core elements: substrate improvement, temperature difference stimulation, and nutrient regulation. It is recommended to take growth record photos every quarter to compare and adjust the details of care. When the side shoots grow to 5cm, they can be propagated by division to obtain new plants.
