Let the plants grow up, how amazing is the led growth lamp?
LED is the abbreviation of Light Emitting Diode. It belongs to semiconductor device. In 1962, LED was applied. Before 1993, LED only had red, green and yellow light devices. It was mainly used as indicator light. LEDs have been industrially produced, and four-element red LEDs and blue LEDs have been gradually developed in plant cultivation. LED applications are called "Solid State Lighting" in the field of lighting, and LED applications are called planting in plants. Artificial light source PARS (LED Plant Artificial Radiation Sources).
LED for planting has the following characteristics:
1. Artificial radiation sources with different wavelength combinations can be manufactured.
2. The conversion efficiency of electric power to radiated power is high.
3. The LED is a cold light source, and the emitted light has no heat radiation.
4. Single-sided illumination mode, the highest utilization rate of optical radiation.
5. The output of the radiation amount can be adjusted by the drive current.
6, the radiation rate attenuation rate is low, the average life expectancy of more than 30,000 hours.
7. Low power consumption and low planting cost.
8, can be driven by low voltage DC, can achieve digital scale control.
9, can easily access solar, wind power supply system.
10. The production process of LED devices will not cause environmental pollution.
Organic farming is a kind of fertilizer, pesticide, growth regulator that does not use chemical synthesis in production, and does not use genetic engineering and ionizing radiation technology. Instead, it follows the laws of nature and adopts agricultural, physical and biological methods to fertilize the soil. , to control pests and diseases, to obtain safe agricultural products and their agricultural production systems.
In fact, organic farming is not completely without fertilizer, but organic fertilizer can be used: farmyard fertilizer, mineral fertilizer, biological fertilizer and so on after high-temperature fermentation and harmless treatment. Based on the limitations of this type of fertilization, the growth cycle of plants must be affected, and the current market demand is in short supply. Therefore, shortening the production cycle is one of them.
The led growth lamp helps to shorten the growth cycle of the plant, because the light source of the lamp is mainly composed of red and blue light sources, using the most sensitive light band of the plant, the red wavelength is 620-630nm and 640-660nm, and the blue wavelength is used. 450-460 nm and 460-470 nm.
Measuring the wavelength of plant growth lamps
These light sources are the best photosynthesis for plants, and the plants are optimally grown. Experiments and practical applications have shown that in addition to giving plants light in the absence of light, it also allows plants to grow more during growth. The differentiation of collaterals and buds accelerates the growth of roots and leaves, accelerates the synthesis of carbohydrates in plants and the synthesis of vitamins, shortening the growth cycle.
With the rapid increase in global demand for organic foods, the development of organic farming is an opportunity for more and more producers.
