Abstract
The invention discloses a method for accelerating plant growth by an LED (Light Emitting Diode) light source, and the method has good growth acceleration action on the whole growth process of plants. The method is characterized in that an LED light source which can emit red light and blue light is used for irradiating plants to accelerate plant growth, wherein the ratio of the red light to the blue light is adjustable, the wavelength of the red light is 610-720 nanometers, and the wavelength of the blue light is 400-500 nanometers. The method for accelerating plant growth is mainly used for irradiating plants during greenhouse planting. According to irradiation, the average growth speed of the plant is about 3 times higher than the growth speed under the natural environment, thereby satisfying the requirements on chlorophyll, anthocyanin and carotene required by photosynthesis of plants in winter; thus, the harvesting time of vegetables and fruits are advanced by 20%, and the yield is increased by 30-50%; and in addition, the sweetness of the vegetables and fruits is improved, and plant diseases and insect pests are reduced.
Description
Technical field
The present invention relates to the led light source that the based semiconductor light emitting diode is made, refer more particularly to the method for utilizing the led light source Promoting plant growth.
Background technology
At present, when greenhouse gardening, usually adopt plant lamp to plant light compensation.During light filling, light source is positioned at about 0.5 meter of plant leaf blade top, and every day, prolonged exposure was 12 ~ 16 hours.
The data record is arranged, and the different wave length line is different for the impact of photosynthesis of plant, the light that photosynthesis of plant needs, and wavelength is between 400 ~ 700 nanometers (nm); And wavelength at the blue light between 400 ~ 500 nanometers (nm) and wavelength the ruddiness between 610 ~ 720 nanometers (nm) maximum for photosynthesis contribution.
The ruddiness of wavelength about 630nm that the wavelength that blue led sends sends in the blue light about 470nm and red LED usually, the light that just can provide plants to need.Therefore, be used for the so-called plant lamp of Promoting plant growth, more satisfactory selection is exactly to use this two kinds of color combination, and blue luminous energy promotes the greenery growth, and red light helps to yield positive results and kind of blooming period prolonging; And on visual effect, the plant lamp of red blue combination presents pink, seems warm soft.
Present LED plant growth lamp, its structure comprises: lamp plate and be welded on a plurality of red LED and a plurality of blue led on the lamp plate.The ruddiness that this LED plant lamp sends and the ratio of blue light are fixed, and between 4 ~ 9:1, more between 6 ~ 9:1, the most frequently used ratio is: 6:1,8:1 or 9:1 etc. usually.The plant growth lamp that this proportion of red blue light is fixing, can only play the effect that well expedites the emergence of to the growth of plant at some growing period of plant, and at other growing period of this plant, then can not play the effect that well expedites the emergence of, namely can not all play in the plant growth overall process and well expedite the emergence of effect.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can all play the method for utilizing the led light source Promoting plant growth that well expedites the emergence of effect to the plant growth overall process.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the method for utilizing the led light source Promoting plant growth, the led light source that employing can be sent the adjustable mixed light of Red and blue light and Red and blue light ratio shines plant, promotes the growth of plant; Wherein, the wavelength of ruddiness is between 610 ~ 720 nanometers, and the wavelength of blue light is between 400 ~ 500 nanometers;
Described led light source comprises the red blue dual-colored LED that can send monochromatic several red LED, several blue leds and ruddiness or blue light can occur; All LED are arranged on several concentric circles, and all blue leds arrange that from inside to outside what arrange on the outmost turns all is red LED.
Described red blue dual-colored LED is arranged on time outer ring, and red blue dual-colored LED is arranged with the red LED interval of enclosing together.
The invention has the beneficial effects as follows: method of the present invention, it is red, the ratio of blue light is adjustable, so just can adopt different mixed lights red, the blue light ratio that it is shone at the different vegetative stages of plant, promote the growth of plant in different phase.Under the condition that guarantees illumination, the average growth rate of plant than the fast growth under the natural environment nearly 3 times, satisfied the in the winter time demand of needed chlorophyll, anthocyan and carotin in the photosynthesis of plant, make vegetables and fruits ahead of time 20% time gather, output increased by 3 to 5 one-tenth; And, also improved the sugariness of vegetables and fruits, reduced damage by disease and insect.
Description of drawings
Fig. 1 is based on the structure of led light source of the present invention and the structural representation of the LED plant growth lamp that makes up.
Among the figure: 1, lamp plate, 2, red LED, 3, red blue dual-colored LED, 4, blue led, 8, shell.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
The method of utilizing the led light source Promoting plant growth of the present invention, the method is: the led light source that employing can be sent the adjustable mixed light of Red and blue light and Red and blue light ratio shines plant, promotes the growth of plant; Wherein, the wavelength of ruddiness is between 610 ~ 720 nanometers, and the wavelength of blue light is between 400 ~ 500 nanometers.
Above-mentioned led light source comprises the red blue dual-colored LED that can send monochromatic several red LED and several blue leds and ruddiness or blue light can occur; All LED are arranged on several concentric circles, and all blue leds arrange that from inside to outside what arrange on the outmost turns all is red LED; Described red blue dual-colored LED is arranged on time outer ring, and red blue dual-colored LED is arranged with the red LED interval of enclosing together.
As shown in Figure 1, a kind of based on above-mentioned led light source structure and the LED plant growth lamp that makes up, its structure comprises: shell 8, be installed in the lamp plate 1 on the shell 8 and be welded on 10 blue leds 4 on the lamp plate 1,70 red LED 2 and 10 red blue dual-colored LED 3, these 90 LED are arranged on 5 concentric circles, wherein, a circle at center is a point, be evenly arranged 9 some positions on the inner ring adjacent with this central point, described 10 blue leds 4 are arranged in central point and with it on 9 some positions of adjacent inner ring; 29 some positions have been evenly arranged on the inferior outer ring, 29 some positions deduct 10 and are used for arranging the some position of red blue dual-colored LED 4, also be left 19 some positions that are used for arranging red LED 2, like this, in order to allow as far as possible red blue dual-colored LED 3 be evenly arranged on time outer ring, at first separate 2 red LED 2 by 1 red blue dual-colored LED 3 and arrange that again the mode of 1 red blue dual-colored LED 3 arranges, last, in remaining position layout red LED 2; Be evenly arranged 36 some positions on the outmost turns, be evenly arranged 15 some positions on the inner ring adjacent with inferior outer ring (from outside to inside several the 3rd circles), altogether 51 the some positions of adding up, 51 remaining red LED 2 are arranged in these 51 some positions.
