What temperature is suitable for the propagation of Epipremnum aureum by cutting
As a representative of indoor ornamental foliage plants, Epipremnum aureum is deeply favored by horticulture enthusiasts for its powerful vitality and air purification ability. Cutting propagation is an important method for cultivating Epipremnum aureum, and temperature control is a key factor affecting the success of cutting, which requires precise grasp by growers.
Core parameters of temperature for cutting Epipremnum aureum
Ideal temperature range analysis
Experimental data shows that 20-30℃ is the best temperature range for cutting Epipremnum aureum. Within this range, the activity of cytokinins is significantly increased, the formation speed of callus at the base of cuttings is accelerated, and new roots can usually germinate in 7-10 days. It is particularly important to note that the day-night temperature difference should be controlled within 5℃, as drastic fluctuations can easily lead to moldy cuts.
Countermeasures for extreme temperatures
When the ambient temperature exceeds 32℃, it is recommended to use a shading net to filter 40% of the light intensity and to cooperate with a spray cooling system. In low-temperature environments in winter, an intelligent temperature control mat can be used to maintain the substrate temperature, combined with a transparent insulation cover to form a miniature greenhouse effect.
Strategies for choosing the timing of cutting Epipremnum aureum
According to regional climatic differences, it is recommended to carry out cutting from April to June in the North China region, and in the South China region, it can be advanced to mid-March. For autumn cutting, the ambient humidity should be ≥65%, which can be achieved through a timed atomization device. In severe cold seasons, it is recommended to preheat the substrate to 25℃ before inserting the cuttings.
Temperature协同 management skills
Light-temperature coupled management
While maintaining a suitable temperature, it is necessary to cooperate with a light intensity of 2000-3000lux. It is recommended to use full-spectrum plant growth lights, with 12-14 hours of daily illumination, which can increase the activity of chloroplasts by 30%.
Substrate temperature monitoring method
Use a dual-probe thermometer to separately monitor the air and substrate temperatures. The substrate temperature should be 2-3℃ higher than the air temperature, which can be precisely controlled through bottom heating wires. Rotate the seedling tray 180 degrees weekly to ensure even temperature distribution.
Temperature regulation in special scenarios
For hydroponic cutting, the water temperature should be kept constant, and it is recommended to use a culture container with heating function. For old branch cutting, the upper temperature limit can be raised to 28℃ to activate dormant buds. For large-scale production, it is recommended to configure an Internet of Things environmental monitoring system to achieve real-time tracking of temperature data.
Through precise temperature management, the survival rate of Epipremnum aureum cutting can be increased to over 90%. It is recommended that growers establish a temperature management log to record changes in temperature parameters at different stages. Combined with modern intelligent horticultural equipment, efficient cutting production can be achieved throughout the year, making the propagation of Epipremnum aureum more scientific and controllable.
