Multi color plant incubatorIt is a professional equipment that provides controllable conditions for plant growth, tissue culture, and photosynthesis research by accurately regulating the combination of multiple monochromatic light sources and simulating different natural light environments. It is widely used in fields such as agricultural science, biotechnology, horticultural breeding, and university research. Its core function is to meet the specific needs of different plants (or different growth stages of plants) for light by adjusting light quality, light intensity, light cycle, and temperature and humidity. It helps to study the effects of light environment on plant physiological metabolism, morphological construction, or cultivate high-quality seedlings.
Multi color plant incubatorCore parameter setting skills:
1. Lighting Settings (Core Techniques):
① Select spectrum (light quality):
Red light (660nm): promotes photosynthesis, stem elongation, and flowering. High proportion red light is commonly used to promote growth.
Blue light (450nm): inhibits stem elongation, promotes chlorophyll synthesis, opens stomata, and enhances antioxidant substances. High proportion of blue light makes plants shorter and stronger.
White light: Provides a full spectrum, close to natural light, often used as base light.
Far red light (730nm): affects light morphogenesis (such as shade avoidance response) and can regulate flowering.
Ultraviolet light (UV-A/UV-B): induces the accumulation of secondary metabolites (such as anthocyanins and flavonoids), enhances resistance, but requires strict control of dosage and time to avoid damage.
Tip: Combine different light colors according to the target. For example, the commonly used ratio for seedling cultivation is red: blue=3:1 or 4:1; High anthocyanin vegetables can be produced by adding blue light and ultraviolet light; Studying the photoperiod can accurately control the ratio of red/far red light.
② Set light intensity (PPFD):
Use a light quantum sensor (PAR sensor) to calibrate the actual light intensity (μ mol/m ²/s) inside the calibration box.
The demand for different plants varies greatly: lettuce can reach about 150-300, tomatoes can reach 600-800, and shade tolerant plants may only need 50-100.
Tip: Use lower light intensity during the seedling stage, gradually increasing with growth to avoid light inhibition.
③ Set the photoperiod:
Accurately set the lighting/darkness time (such as 16h/8h). The flowering of many plants is regulated by the photoperiod (long day, short day plants).
Tip: You can set a gradient mode (simulating sunrise and sunset) to reduce plant stress.
2. Temperature control:
Setting the temperature difference between day and night: Simulating the natural environment is beneficial for material accumulation. For example, 25 ° C during the day and 18 ° C at night.
Uniformity: Ensure even temperature distribution inside the box, avoiding local overheating (near the lamp) or overcooling.
Tip: Temperature setting needs to be coordinated with lighting. The temperature should not be too high under strong light to prevent burns.
3. Humidity control:
Set target humidity: Most plants are suitable for 60-80% RH. High humidity can easily breed bacteria, while low humidity can cause rapid transpiration.
Humidification and dehumidification: Ensure that the humidification water tank has water and the drainage pipe is unobstructed. Regularly clean the humidifier to prevent clogging and algae growth.
Tip: At the beginning of the lighting, the humidity can be slightly higher; The dark period can be appropriately reduced to minimize condensation.
4. CO ₂ concentration control (if available):
Set concentration: usually set at 800-1200 ppm (higher than 400 ppm in the atmosphere), which can significantly promote photosynthesis.
Tip: CO ₂ supplementation is only performed during periods of light exposure, and is not necessary during periods of darkness. Ensure that the CO ₂ gas source is pure and the pipeline is leak free.
