Problems solved by technology

[0003] The current method for promoting plant growth generally uses a high-luminous flux sodium lamp as a light source to supplement light irradiation on plants. Although the above-mentioned method and device can meet the light requirements of plant photosynthesis, it is expensive, consumes a lot of energy and consumes a lot of light. General efficiency, short service life, high cost, and because the sodium lamp light source is a heat light source, it is easy to cause fire and short circuit, which is not conducive to popularization and promotion

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing of description:

[0020] figure 1 Shown is the plant chlorophyll absorption spectrum measured by botanists, the horizontal axis is the wavelength, and the vertical axis is the absorbance. It can be seen from the figure that the absorption of chlorophyll to sunlight is mainly concentrated in the red light around 660nm of visible light, and the red light around 460nm. Near blue light and purple light around 400nm, and it is estimated that the peak energy ratio of plant chlorophyll absorption spectrum red (around 660nm), blue (around 460nm), and purple (around 400nm) is 60:39:18.

[0021] The method of using LED light sources to regulate plant growth, that is, artificially simulating the best growth lighting environment for plants, choosing to use the mixed light of different LED light sources to irradiate plants, improving the lighting conditions of crops to promote plant growth...

Abstract

The present invention relates to a method for regulating plant growth by utilizing LED light source and its equipment, belonging to the field of plant growth regulation and electronic technique. It ischaracterized by selecting and utilizing mixed light formed from different LED light sources to irradiate plant so as to promote growth of plant. Said equipment includes constant voltage power supplydevice, reference voltage device, constant current source device and irradiation light source device, etc.

Description

technical field [0001] The invention belongs to the field of plant growth regulation and electronic technology, and in particular relates to a method and a device for regulating plant growth by using an LED light source. Background technique [0002] Light is the energy source of all life on earth and one of the most important factors for the survival of all living things in the world. The origin and evolution of life cannot be separated from light, and the structure and function of living things are also strongly affected by light. The growth of green plants requires sunlight, mainly because they need to carry out photosynthesis to provide the nutrients they need for their own growth. The results of plant physiology research show that 90% of the dry matter weight of crops comes from photosynthesis, which reflects that the influence of light on crop yield is very important. The spectrum of sunlight is continuous and contains a huge spectral width, while the chlorophyll of g...
