Detailed Description
The following description is provided for illustrative embodiments of the present invention, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. While the invention will be described in conjunction with the preferred embodiments, it is not intended that features of the invention be limited to only those embodiments. On the contrary, the intention of implementing the novel features described in connection with the embodiments is to cover other alternatives or modifications which may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Furthermore, some of the specific details are omitted from the description so as not to obscure or obscure the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Additionally, the terms "upper," "lower," "left," "right," "top," "bottom," "horizontal," "vertical" and the like as used in the following description are to be understood as referring to the segment and the associated drawings in the illustrated orientation. The relative terms are used for convenience of description only and do not imply that the described apparatus should be constructed or operated in a particular orientation, and therefore should not be construed as limiting the invention.
It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers and/or sections should not be limited by these terms, but rather are used to distinguish one element, region, layer and/or section from another element, region, layer and/or section. Thus, a first component, region, layer and/or section discussed below could be termed a second component, region, layer and/or section without departing from some embodiments of the present invention.
As described above, the existing plant growing technology is mainly performed by open air cultivation. In traditional planting patterns, photosynthesis of plants relies primarily on solar radiation to provide energy. During photosynthesis, green plants absorb solar energy to hydrate carbon dioxide and water into energy-rich organic substances such as carbohydrates and release oxygen.
Research shows that in a certain illumination intensity range, the photosynthesis intensity is enhanced along with the enhancement of the illumination intensity. However, when the illumination intensity reaches a certain intensity, the photosynthesis intensity is not increased correspondingly due to the light saturation phenomenon commonly existing in plants. Therefore, the speed of the dark reaction can be increased to make crops fully utilize the light energy absorbed by the light reaction, thereby improving the light saturation point and the utilization efficiency of the light energy. That is, under the light saturation condition, compared with the conventional sunlight irradiation in the steady state form, the irradiation form of the pulsed light can effectively improve the efficiency of the photosynthesis of the plant, thereby promoting the growth of the plant.
In order to solve the problem of food shortage, the present invention is based on the embodiments that provide an apparatus for promoting plant growth, and an embodiment of a method for promoting plant growth, for enhancing photosynthesis of plants to promote synthesis of organic substances, thereby improving productivity and yield of crops.
Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating a plant growth promoting device according to an aspect of the present invention.
As shown in fig. 1, the device for promoting plant growth provided by this embodiment may include: the device comprises a power module 11, a rotating module 12 and a shielding module 13, wherein the power module 11 can be used for providing energy for driving the rotating module 12 to rotate; the rotation module 12 may rotate in response to the power supplied from the power supply module 11; the shielding module 13 can be connected to the rotating module 12 and rotate with the rotating module 12 to shield the light emitted from the light source 14 to the plants 151 and 154 below the shielding module 13, so as to realize the pulse irradiation of the light source 14 to the plants 151 and 154 without changing the light emitting manner of the light source 14.
It can be understood by those skilled in the art that, since the device for promoting plant growth provided in this embodiment is based on the principle of promoting photosynthesis of the plants 151-154, the plants 151-154 need to have substantial photosynthesis capacity. In some embodiments, the plants include, but are not limited to, plants having photosynthetic capacity such as spirulina, arabidopsis, wheat, and rice.
In one embodiment, the power module 11 may be a solar cell. Accordingly, the sun may be directly used as the light source 14 of this embodiment. That is, the device for promoting plant growth provided by this embodiment can be operated in the open-air environment of the sun 14 for enhancing photosynthesis of the plants 151 and 154 to promote synthesis of organic substances, thereby improving the yield and yield of crops.
Specifically, the solar cell 11 may be more preferably a low-cost small-capacity solar cell. The solar cell 11 may generate electrical energy in response to being illuminated by the sun 14. The rotating module 12 can rotate in response to the electric energy provided by the solar cell 11, so as to drive the shielding module 13 to rotate together, so as to shield the sun 14 from illuminating the plants 151 and 154 below the shielding module 13. The preferred scheme of using the small-capacity solar cell 11 not only can significantly reduce the production cost of the plant growth promoting device, but also can respond to the condition that the solar light cannot be irradiated and stop supplying power in time, thereby reducing the mechanical aging condition of the rotating module 12 and prolonging the service life of the plant growth promoting device.
It will be appreciated by those skilled in the art that the use of the sun 14 as a light source is a preferred solution provided by the present embodiment, and can be used to eliminate the production cost and the electric energy cost of the artificial light source during operation. In addition, the full spectrum of radiation emitted by the sun 14 can adequately meet the wavelength requirements for photosynthesis by a variety of different plants, thereby further promoting photosynthesis by the different plants.
Please refer to fig. 2 in combination, fig. 2 shows a schematic structural diagram of a shielding module according to an embodiment of the present invention.
As shown in fig. 2, in one embodiment, the apparatus for promoting plant growth may include three shutter modules 13. The shielding module 13 may preferably be a fan-shaped structure, so that the plants 151 and 152 at different positions under the shielding module 13 can be irradiated by the pulse light with the same frequency and the same pulse width, so as to irradiate the plants 151 and 154 with the pulse light with the optimal frequency and pulse width for obtaining the highest photosynthesis efficiency.
It can be understood by those skilled in the art that the three shielding modules 13 provided in the present embodiment are only a specific case, and are mainly used to clearly illustrate the concept of the present invention, and provide a specific solution for the public to implement, not to limit the protection scope of the present invention.
In another embodiment, a person skilled in the art can also use only one shielding module 13 to perform the method for promoting plant growth, thereby simplifying the structure of the device for promoting plant growth.
In other embodiments, those skilled in the art may also adopt any other number of shielding modules 13 to perform the method of promoting plant growth, so as to adjust the irradiation frequency of the pulsed light.
Those skilled in the art will also understand that the number and central angle of the shielding modules 13 of the fan-shaped structure can be determined according to the photosynthesis efficiency of the plants 151 and 154. Accordingly, the width of the shielding module 13 may be further determined according to the central angle.
Specifically, the optimal frequency and duty cycle parameters of the pulsed light can be determined according to the photosynthesis efficiency of the plants 151 and 154. Further, the number of the shielding modules 13 may be determined according to the ratio of the optimal frequency to the rotation frequency of the rotation module 12. From the product of 360 ° and the duty cycle parameter, the sum of the central angle of all the occlusion modules 13 can be determined. Then, the central angle of each shielding module 13 can be determined by the ratio of the sum of the central angles of all the shielding modules 13 to the number of the shielding modules 13.
In one embodiment, the rotating module 12 may be a motor driven by electric energy. The motor 12 may operate in response to the input voltage exceeding its starting voltage threshold.
Specifically, based on the principle of the photovoltaic effect, the voltage generated by the solar cell 11 may increase as the intensity of illumination increases. At the same time, the photosynthesis efficiency of the plants 151-154 will also increase with the increase of the illumination intensity, thereby obtaining higher productivity and yield. When the illumination intensity of the sun 14 reaches the saturation illumination intensity of the plants 151-154, the plants 151-154 will have light saturation phenomenon, so that the photosynthesis efficiency of the plants 151-154 decreases with the enhancement of the illumination intensity, thereby preventing the productivity and yield of the plants 151-154 from being further improved.
Referring to table 1 and fig. 3 in combination, table 1 shows absorbances (OD values) of the alga clathratus 6803 (blue-green algae) corresponding to different illumination intensities provided according to an embodiment of the present invention, wherein the absorbances (OD values) of the alga clathratus are linearly related to the photosynthesis efficiency thereof, thereby indicating the photosynthesis efficiency of the alga clathratus. Fig. 3 shows a graph of absorbance of alga clathrates as a function of illumination intensity according to an embodiment of the present invention.
TABLE 1
As shown in Table 1 and FIG. 3, under the irradiation of conventional DC sunlight, Bambucus 6803 was found to be 432. mu. mol/m2S, and exhibits a phenomenon in which the photosynthesis efficiency is reduced at a higher light intensity. That is, the plants such as Baglena only have a concentration of 432 μmol/m, limited by the illumination pattern of the conventional planting technique2S, while higher yields and yields are not obtained by further enhancing the illumination intensity.
In contrast, under the irradiation of the pulsed sunlight provided by the present embodiment, Bambucus 6803 can be at 606 μmol/m2S light intensity, the phenomenon of light saturation occurs. Therefore, under the same OD value of 1.52, Bambucus 6803 can absorb more light energy to synthesize organic substances, thereby obtaining higher productivity and yield.
In addition, as can be seen from Table 1 and FIG. 3, the above-mentioned pulseThe irradiation form of the light is not capable of making the plants 151-154 have higher photosynthesis efficiency under any illumination intensity. At 432. mu. mol/m2At an illumination intensity of s or less, the OD value of the synechocystis 6803 under the pulsed light irradiation may be lower than that under the direct current irradiation.
Therefore, in this embodiment, in order to further improve the productivity and yield of the plants 151 and 154, the solar cell 11 and the motor 12 can be selected accordingly, so that the threshold of the starting voltage of the motor 12 is exactly equal to or close to that of the solar cell 11 at 432 μmol/m2S the voltage generated at the illumination intensity.
When the intensity of the sun 14 is equal to or higher than 432. mu. mol/m2S, the solar cell 11 may respond to exposure to greater than 432. mu. mol/m2S, to generate a voltage above the starting voltage threshold, thereby driving the motor 12 to rotate to effect pulsed irradiation of the plant 151-154 by the sun 14.
For example: when the illumination intensity of the sun 14 is 620 mu mol/m2S, the solar cell 11 can generate voltage to drive the motor 12 to rotate, thereby driving the fan-shaped shielding device 13 to rotate to generate the pulse sunlight with the duty ratio of 50% -80% (preferably 66.7%) and the frequency of 12.5 Hz. At this time, the OD value of the pulsed sunlight close to 1.52 means significantly higher photosynthesis efficiency than the OD value of the direct sunlight of 1.19, so that higher plant productivity and yield can be obtained.
As will be appreciated by those skilled in the art, the above Synechocystis collectici 6803 and its corresponding 432. mu. mol/m2S, which is a plant case provided in this embodiment, is mainly used to clearly show the concept of the present invention and to provide a specific solution for the public to implement, not to limit the protection scope of the present invention. The technical personnel in the field can also be based on the conception of the utility model, apply the device and the method for promoting the plant growth to any other plants with photosynthesis ability such as spirulina, arabidopsis thaliana, wheat and rice, thereby realizing the effect of promoting the synthesis of organic substances and improving the plant productivity and yield.
In a preferred embodiment, in order to prevent the static shielding module 13 from shielding the plants 151 and 154 thereunder when the illumination intensity is low, the shielding module 13 can also be preferably configured to be a flexible structure or a retractable structure.
Referring further to fig. 4A and 4B, fig. 4A is a schematic structural diagram of a flexible shielding module according to an embodiment of the present invention; fig. 4B shows a schematic structural diagram of the retractable shielding module according to an embodiment of the present invention.
As shown in fig. 4A, in one embodiment, the shielding module 13 may be a flexible structure made of flexible materials such as rubber, soft plastic, etc.
When the motor 12 is not rotated or the rotation speed is lower than a certain rotation speed threshold, the shielding module 13 can naturally droop under the action of gravity, so as not to shield the sun 14 from the illumination of the plants 151 and 154 below. The above-mentioned rotation speed threshold value may be determined according to the length and weight of the shielding module 13.
When the voltage applied to the motor 12 is higher than the starting voltage threshold, the motor 12 can drive the shielding module 13 to rotate together at a speed higher than the rotation speed threshold. Under the centrifugal action, the shielding module 13 can be naturally supported as shown in fig. 1, and intermittently shields the illumination of the plants 151 and 154 below the shielding module from the sun 14, so as to generate the sunlight in the form of pulses for the plants 151 and 154.
As shown in FIG. 4B, in one embodiment, the shelter module 13 can be a telescopic structure, and further comprises one or more telescopic joints 131 for the shelter module 13 to telescope. The telescopic joint 131 may be provided therein with a micro-elastic structure that contracts inward.
When the motor 12 does not rotate or the rotation speed is lower than a certain rotation speed threshold value, the shielding module 13 can be retracted inwards under the action of the micro-elastic structure, so that the illumination of the sun 14 to the plants 151 and 154 below is not shielded. The rotational speed threshold value and the retraction force of the micro-elastic means can be determined in conjunction with one another.
When the voltage applied to the motor 12 is higher than the starting voltage threshold, the motor 12 can drive the shielding module 13 to rotate together at a speed higher than the rotation speed threshold. Under the centrifugal action, the shielding module 13 can extend outwards as shown in fig. 4B and intermittently shield the sun 14 from illuminating the plants 151-154 therebelow, so as to generate the sunlight in a pulse form for the plants 151-154.
Those skilled in the art can understand that the flexible structure and the retractable structure are only two preferable solutions provided by this embodiment, and are mainly used to prevent the static shielding module 13 from shielding the plants 151 and 154 therebelow when the illumination intensity is low, so as to influence the growth speed of the plants 151 and 154, rather than limiting the protection scope of the present invention. In other embodiments, those skilled in the art can also adopt other structures of shielding modules to obtain the same effect of avoiding shielding light based on the concept of the present invention.
In one embodiment, in order to get rid of the limitation of natural conditions such as weather, day and night variation, and further utilize the time of rainy day and night to promote the plant growth, the plant growth promoting device may further include an artificial light source 16 disposed above the shielding module 13. The spectral radiation distribution and the radiation intensity of the artificial light source 16 can be determined by the photosynthesis efficiency of the plants 151 and 154.
Referring to fig. 5, fig. 5 is a schematic structural diagram illustrating a device for promoting plant growth according to an embodiment of the present invention.
As shown in fig. 5, the artificial light source 16 may preferably be an LED light source. Compared with traditional black-body light sources such as incandescent lamps and halogen tungsten lamps, the LED light source 16 has the obvious advantage of low energy consumption, so that the operation cost of the plant growth promotion device can be greatly reduced. Compared with gas discharge light sources such as mercury lamps and sodium lamps, the LED light source 16 has the advantage that the spectral radiation intensity distribution can be adjusted at will, so that the plants can be irradiated by the light with the highest photosynthesis efficiency according to the photosynthesis efficiency of various plants under the irradiation of the light with different wavelengths to obtain the highest productivity and yield.
In this embodiment, the LED light source 16 may emit red light with a peak wavelength of 625nm to illuminate high carbon (carbon dioxide, CO)2) Environmental plants 151-. The plants 151-154 can efficiently obtain the light energy in the red light, thereby utilizing the dioxideCarbon and water form energy-rich organic substances such as carbohydrates, and oxygen is released.
In a more preferred embodiment, the LED light source 16 may further cooperatively emit a far-red light with a wavelength of 730nm to illuminate plants, such as sugarcane, trees, and the like, whose stems are the main crops. The 730nm far-red light can simulate the shade-avoiding effect among plants, so that the plant 151-154 irradiated by the LED light source 16 mistakenly shades the direct light of the sun by another higher plant, and further the plant 151-154 is promoted to grow stems more hard to break through the shading.
According to another aspect of the present invention, there is also provided herein an embodiment of a method of promoting plant growth.
Referring to fig. 1 and 6 in combination, fig. 6 is a schematic flow chart illustrating a method for promoting plant growth according to another aspect of the present invention.
As shown in fig. 6, the method for promoting plant growth provided by this embodiment may include the steps of:
601: the power supply module supplies power to the rotating module to drive the rotating module to rotate; and
602: the shielding module connected with the rotating module rotates along with the rotating module so as to shield the illumination of the plant below the shielding module by the light source.
In one embodiment, the power module 11 may be a solar cell. Accordingly, the sun may be directly used as the light source 14 of this embodiment. That is, the device for promoting plant growth provided by this embodiment can be operated in the open-air environment of the sun 14 for enhancing photosynthesis of the plants 151 and 154 to promote synthesis of organic substances, thereby improving the yield and yield of crops.
In this embodiment, step 601 may further include the steps of: irradiating the solar cell with the sun to generate electric power; and rotating the rotation module when the solar cell is powered. And step 602 may further include the steps of: the shielding module rotates along with the rotating module to shield the illumination of the plants below the shielding module from the sun.
It can be understood by those skilled in the art that, since the method for promoting plant growth provided in this embodiment is based on the principle of promoting photosynthesis of the plants 151-154, the plants 151-154 need to have substantial photosynthesis capacity. In some embodiments, the plants include, but are not limited to, plants having photosynthetic capacity such as spirulina, arabidopsis, wheat, and rice.
In one embodiment, the rotating module 12 may be a motor driven by electric energy. The motor 12 may operate in response to the input voltage exceeding its starting voltage threshold.
Accordingly, the method for promoting plant growth may further comprise the steps of: enabling the solar cell to generate a voltage higher than a preset starting voltage threshold value when the solar cell is subjected to sunlight radiation with the intensity higher than a preset intensity; and rotating the rotation module when the solar cell provides a voltage above a starting voltage threshold.
In a preferred embodiment, in order to prevent the static shielding module 13 from shielding the plants 151 and 154 therebelow when the illumination intensity is low, the method for promoting the plant growth can also preferably select the shielding module 13 with a flexible structure or a retractable structure.
As shown in fig. 4A, in an embodiment, the method for promoting plant growth may further include: responding to the fact that the rotating speed of the rotating module is lower than a preset rotating speed threshold value, enabling the flexible shielding module to droop without shielding the illumination of the sun on the plants below; and responding to the rotating speed of the rotating module being higher than a preset rotating speed threshold value, enabling the flexible shielding module to be supported to shield the illumination of the sun to the plants below the flexible shielding module.
As shown in fig. 4B, in an embodiment, the method for promoting plant growth may further include: in response to the rotating speed of the rotating module being lower than a preset rotating speed threshold, the retractable shielding module is retracted without shielding the illumination of the sun on the plants below; and in response to the rotating speed of the rotating module being higher than a preset rotating speed threshold, the retractable shielding module is extended out to shield the sun from illuminating the plants below the retractable shielding module.
Those skilled in the art can understand that the flexible structure and the retractable structure are only two preferable solutions provided by this embodiment, and are mainly used to prevent the static shielding module 13 from shielding the plants 151 and 154 therebelow when the illumination intensity is low, so as to influence the growth speed of the plants 151 and 154, rather than limiting the protection scope of the present invention. In other embodiments, those skilled in the art can also adopt other structures of shielding modules to obtain the same effect of avoiding shielding light based on the concept of the present invention.
As shown in fig. 2, in one embodiment, the method for promoting plant growth can be performed by using three fan-shaped shielding modules 13. The method for promoting plant growth can further comprise the following steps: the width and the number of the shielding modules are determined according to the radiation intensity of the light source, the rotating speed of the rotating module and the photosynthesis efficiency of the plants.
Specifically, the number and the central angle of the shielding modules 13 of the fan-shaped structure can be determined according to the photosynthesis efficiency of the plants 151 and 154. Accordingly, the width of the shielding module 13 may be further determined according to the central angle.
In the above method for promoting plant growth, the optimal frequency and duty cycle parameters of pulsed light can be determined according to the photosynthesis efficiency of the plants 151 and 154. Further, the number of the shielding modules 13 may be determined according to the ratio of the optimal frequency to the rotation frequency of the rotation module 12. From the product of 360 ° and the duty cycle parameter, the sum of the central angle of all the occlusion modules 13 can be determined. Then, the central angle of each shielding module 13 can be determined by the ratio of the sum of the central angles of all the shielding modules 13 to the number of the shielding modules 13.
In one embodiment, in order to get rid of the limitation of natural conditions such as weather, day and night variation, and further utilize the time of rainy day and night to promote the plant growth, the method for promoting the plant growth can be further performed by an artificial light source 16 disposed above the shielding module 13.
Correspondingly, the method for promoting plant growth can further comprise the following steps: the radiation intensity of the light source disposed above the shielding module is determined according to the photosynthesis efficiency of the plant.
In a preferred embodiment, the artificial light source 16 may preferably be an LED light source. Compared with traditional black-body light sources such as incandescent lamps and halogen tungsten lamps, the LED light source 16 has the obvious advantage of low energy consumption, so that the operation cost of the plant growth promotion device can be greatly reduced. Compared with gas discharge light sources such as mercury lamps and sodium lamps, the LED light source 16 has the advantage that the spectral radiation intensity distribution can be adjusted at will, so that the plants can be irradiated by the light with the highest photosynthesis efficiency according to the photosynthesis efficiency of various plants under the irradiation of the light with different wavelengths to obtain the highest productivity and yield.
Correspondingly, the method for promoting plant growth can further comprise the following steps: and determining the spectral radiation intensity distribution of the LED light source arranged above the shielding module according to the photosynthesis efficiency of the plant.
In this embodiment, the LED light source 16 may emit red light with a peak wavelength of 625nm to illuminate high carbon (carbon dioxide, CO)2) Environmental plants 151-. The plants 151-154 can efficiently acquire the light energy in the red light, thereby utilizing the carbon dioxide and the organic substances rich in energy such as water synthesized carbohydrates and releasing oxygen.
In a more preferred embodiment, the LED light source 16 may further cooperatively emit a far-red light with a wavelength of 730nm to illuminate plants, such as sugarcane, trees, and the like, whose stems are the main crops. The 730nm far-red light can simulate the shade-avoiding effect among plants, so that the plant 151-154 irradiated by the LED light source 16 mistakenly shades the direct light of the sun by another higher plant, and further the plant 151-154 is promoted to grow stems more hard to break through the shading.
