The Cultivation Method of Spiranthes
As a class II protected wild plant in the country, Spiranthes is highly regarded for its unique spiral inflorescence and medicinal value. This miniature orchid, known as "Dragon Bone参", requires special attention in adjusting the growing environment for home care. This article will systematically analyze the key points of cultivating Spiranthes at home, helping growers create a suitable growing environment.
Adjustment of Spiranthes Growing Environment
Temperature and Humidity Management Requirements
Spiranthes grows best in a warm and humid environment between 15-25°C. Ventilation and cooling are necessary in the summer, while the temperature should not drop below 5°C in winter. It is recommended to use a thermometer and hygrometer to monitor, with the optimal growth at an air humidity of 60-70%.
Control of Light Intensity
Use a scattered light care mode, where direct sunlight can be accepted in the morning and evening during spring and winter, and a shading net should be used to filter 50% of the light in the summer. During the flowering period, ensure at least 4 hours of soft light daily to avoid leaf burn from strong light.
Spiranthes Propagation Management Techniques
Seed Propagation Tips
The Cultivation Method of Spiranthes
When sowing, use a mixture of peat soil and perlite in a 3:1 ratio, maintaining a constant temperature of 20°C. After sowing, cover with plastic wrap to maintain humidity, which takes about 90 days to germinate. It is recommended to sow in spring, with a survival rate of over 70%.
Daily Care Techniques
Use the "dry-wet alternation" watering method, watering thoroughly when the topsoil is dry by 2cm. During the growing season, spray 0.1% potassium dihydrogen phosphate solution every 10 days, and apply calcium and magnesium fertilizer before the flowering period to promote bud differentiation.
Common Disease and Pest Control
Disease Treatment Plan
In the early stage of rust disease, use a 25% triadimefon wettable powder at 1500 times dilution for control, and for white rot disease, use a 50% carbendazim solution at 800 times dilution for root irrigation. It is recommended to use wood ash water for preventive disinfection once a month.
