The Manifestation and Treatment of兰花 Not Adapting to the Pot
Beginners often encounter the problem of兰花 plants not growing for a long time, which is often closely related to the兰花 not successfully adapting to the pot. This article analyzes typical symptoms and coping strategies to help orchid enthusiasts master the management essentials during the兰花 slow growth period.
I. Three Typical Symptoms of兰花 Not Adapting to the Pot
1. Abnormal Leaf Symptoms
Leaves show signs of dehydration and curling, with leaf tips becoming withered and accompanied by the spread of black spots. The disappearance of the healthy orchid leaves' lustrous appearance indicates that the roots have failed to absorb water properly. According to statistics from horticultural experts, 85% of the cases where兰花 fail to adapt to the pot show leaf cuticle shrinkage.
2. Hindered Growth of New Shoots
New leaf buds stop growing and form僵苗, and if the height is less than 2cm within 3 weeks after emerging from the soil, it is a cause for concern. Normally adapted兰花 plants should produce 1-2 new leaves per month, and if no new shoots appear for 60 consecutive days, it is considered not adapted to the pot.
3. Abnormal Root Growth
New root tips appear in a glassy transparent state, and old roots harden and lose elasticity. Under a microscope, it can be observed that the root hair development of兰花 that have not adapted to the pot is poor, with an absorption area 70% less than that of normal roots.
II. Four Steps to Solve兰花 Adaptation Problems
1. Wake Up Dormant Plants
Use the all-vegetable nutrient solution immersion method: immerse the兰花 plants in a balanced solution with an EC value of 0.8ms/cm for 2 hours, repeating once a week for three weeks. Experimental data show that this method can increase root vitality index by 300%.
2. Scientific Proportion of Growing Media
Golden particle proportioning scheme: pine bark (40%) + volcanic rock (30%) + stone (20%) + bamboo charcoal (10%), particle size controlled between 8-15mm. This structure ensures porosity of 35% and water retention rate at the ideal value of 45%.
3. Precise Environmental Control
Set up a transition care area: maintain a temperature of 22±2°C, humidity of 65%-75%, and light intensity of 5000-8000Lux. It is recommended to use smart environmental monitoring devices; stable environments can increase the success rate of adaptation to the pot to 90%.
4. Intelligent Water Management
Use the 'dry-wet alternating stimulation method': keep the substrate moist for the first 3 days after potting, and start implementing the 'dry-wet' strategy on the 4th day. By monitoring with a tensiometer, when the substrate water potential reaches -10kPa, water is supplemented. This method can increase the speed of new root germination by 40%.
Through systematic management, 90% of兰花 that have not adapted to the pot can resume growth within 45 days. Regularly checking growth data and adjusting the care plan based on plant feedback is the key to ensuring兰花 successfully passes the slow growth period.
