Principles of Plant Suffocated Cultivation
In horticulture care, optimizing the plant growth environment through special methods has become a common practice. Suffocated cultivation, as a short-term promotion technique, effectively improves the growth status of plants such as succulents and ferns by constructing a miniature greenhouse environment, making the leaves plumper and more translucent. This method requires precise control of temperature and humidity balance to achieve the best results.
Scientific Principles of Plant Suffocated Cultivation
Greenhouse Effect and Microclimate Construction
After covering a transparent container to form a sealed space, sunlight passing through the medium accumulates heat, which can increase the internal temperature by 3-5°C compared to the ambient temperature. This temperature difference, combined with an 85%-95% humidity environment, can activate the activity of plant cell division enzymes and accelerate the efficiency of nutrient transport.
Humidity and Temperature Synergistic Effect
When the air humidity is stable at around 90%, the plant stomata remain open, and combined with the golden temperature range of 25-28°C, the efficiency of photosynthesis can be increased by 40%. This synergistic effect can make the window surface of Echeveria succulents more transparent and the leaf veins of plants like Nephrolepis more distinct.
Plant Suffocated Cultivation Implementation Standards
Seasonal Selection and Time Control
The best effect of suffocated cultivation is from 10:00 to 15:00 daily in spring and autumn, and it is recommended to keep a single session duration within 5 hours. In the high-temperature period of summer, the operation needs to be completely stopped, and in winter, it can be appropriately extended to 8 hours depending on the greenhouse conditions.
Container Selection and Covering Techniques
It is recommended to use a transparent acrylic cover with vent holes or food-grade PE plastic wrap with holes. When covering, leave 1/5 space for air circulation, and keep a 2cm gap between the container edge and the pot to avoid contact with the leaves.
Key Points of Plant Suffocated Cultivation Care
Key Points of Timed Ventilation
Remove the cover for ventilation 3 times a day, each time for at least 30 minutes. The segmented ventilation method of morning, noon, and evening can be used, and combined with 50% shading net to avoid abrupt temperature changes.
Scientific Watering Methods
Use a siphon watering device to keep the matrix moisture content at 40%-50%, and avoid direct spraying on the leaf heart. It is recommended to use pure water with a TDS value less than 50, and supplement trace amounts of calcium and magnesium elements weekly.
Selection of Suitable Plant Types
Suitable varieties include: epiphytic ferns like Platycerium, succulents like Sempervivum, and moss micro landscapes. Suffocated cultivation is prohibited for plants like Crassula with thick leaves and cacti to prevent rotting.
By accurately controlling temperature and humidity parameters and operation duration, suffocated cultivation technology can significantly improve the ornamental value of specific plants. It is recommended to develop personalized care plans based on the physiological characteristics of plant physiology, regularly observe growth responses, and timely adjust the implementation intensity to achieve safe and effective environmental control.
