Fig. 1 provides a mobile device for agricultural lighting that serves to meet some intermittent or varying lighting or light providing needs within a relatively fixed structure field, which may preferably be considered a mobile light source. The relatively fixed structure site can be an indoor environment of some houses, plant sheds, buildings and large sites, or can be a semi-open site built or surrounded by fences, half walls and support frames, or in some special embodiments, the site can be a completely open site, such as a field, a square and the like. A preferred use of the invention is for mobile lighting of planting or farming areas, such as usually pre-divided areas of cultivation, for example, plots in the field, cultivation shelves in indoor plantations or cultivation rooms, where plants or animals may require long periods of light, especially where most economically valuable cultivated plants need photosynthesis to be grown and harvested more quickly. The problem that plants can not receive light almost at dark night approximately one third of the day caused by rising west and falling of the sun is solved, mature equipment for providing enough light for animals and plants, such as a planting box, a fluorescent lamp turned on in a cultivation fence for a long time, a cultivation lamp and the like, is already available in the market, however, the equipment is fixedly installed, and in order to ensure the irradiation range and the irradiation intensity of light, a surrounding type lamp combination is usually arranged on each cultivation frame or each planting land block in the cultivation place 500, and for larger cultivation manufacturers, the construction investment of light and the subsequent expenditure of electricity charges and maintenance charges are quite huge. Therefore, the dynamic light source 310 device provided by the present invention can move back and forth to and from each position in the cultivation site 500, and uniformly irradiate all the cultivation objects in the cultivation site 500 with its own divergent light, so as to effectively reduce the construction cost of the irradiation lamp.

The present invention includes at least a moving part 200, an illuminating part 300, a driving part 400, and a trajectory 100. The illuminating part 300 is disposed or connected to the moving part 200 and moves on the track 100 along with the moving part 200, and the driving part 400 is used to provide a power source for the moving part 200. The track 100 defines the direction of the driving part 400 in the cultivation site 500, in this embodiment, the track 100 is defined by a rail hung on the top of the cultivation site 500, and the moving part 200 moves in a fixed line by using the rail clamped above the cultivation object, but in other possible embodiments, the track may be a road arranged on the ground of the cultivation site 500 or a virtual line divided by a line boundary device recognizable by a sensor, and the moving part 200 may be arranged on the ground to move, for example, an automatic line patrol robot may be used to realize similar moving requirements.

In the present embodiment, the trajectory 100 is assumed to be at the top of the breeding site 500 and, preferably, the trajectory 100 has a meandering path arrangement according to the house type structure of the breeding site 500 and the division of the breeding area. In order to fix the moving part 200, it is preferable that the track 100 is configured to have at least two horizontal beams distributed vertically to the ground and a vertical beam 120 sandwiched and connected between the two horizontal beams, for convenience of description, a position far from the ground is referred to as a far end, a position close to the ground is referred to as a near end, a section of the beam disposed at the far end is referred to as a first beam 110, a section of the beam disposed at the near end is referred to as a second beam 130, a start point 180 and an end point 190 of the vertical beam 120 are respectively disposed on the path points of the first beam 110 and the second beam 130, and it is preferable that the vertical beam 120 is configured to be vertically oriented to the ground by adjusting the start point 190 and the end point 190 of the vertical beam 120, and it is further preferable that the start point 180 and the end point 190 of the vertical beam 120 are respectively disposed at the middle point of the path of the first beam 110 and the second beam 130, so that a straight line defined through the center of the shape of the vertical beam 120 and along its fore-aft extension can just bisect the path length of the first cross beam 110 or the second cross beam 130.

In order to fix the track 100 on the top of the cultivation site 500, the mounting grooves 140 with the same direction are fixed on the top of the cultivation site 500 according to the expected path of the track 100, each cross section of the mounting groove 140 on the path is substantially the same design, the cross section is substantially a hollow cavity structure with an opening partially opened on one side facing the ground, the hollow cavity structure can be a hollow rectangular structure, preferably, the opening size is set according to the transverse width of the vertical beam 120 of the track 100, so that the two ends of the first cross beam 110 arranged at the far end can be supported on the inner side of the mounting groove 140 near the opening. Preferably, the width of the mounting groove 140 in the horizontal direction is set in a manner of matching the length of the first beam 110 in the same direction, and a certain expansion gap is provided, so that the side surface of the first beam 110 can be better limited by the mounting groove 140 without shaking left and right in the horizontal direction. After the first cross member 110 is disposed in the mounting groove 140, it is passed through and fixed to the top of the cultivation site 500 by means of mounting screws 141 through mounting holes opened at positions of the mounting groove 140 corresponding to the first cross member 110.

The moving part 200 moving on the trajectory 100 includes at least a carriage 220 and a roller 210. At least two or even number of rolling surfaces of the roller 210 symmetrically contact with the side of the second beam 130 of the track 100 away from the ground except the position where the vertical beam 120 is connected, the roller 210 moves on two sides of the second beam 130, preferably, the axial width of the roller 210 is completely contained in the extension range of the second beam 130, so that all the rolling surfaces of the roller 210 fall on the second beam 130 to prevent the roller 210 from falling off, preferably, two ends of the second beam 130 in the horizontal direction respectively extend upwards for at least a distance in the direction away from the ground to form side stoppers 131, and the side stoppers 131 are used for preventing the roller 210 from falling off from the side of the second beam 130. Preferably, the distance between each side stop 131 and the side wall of the vertical beam 120 on the same side is set in a manner matching the axial width of the roller 210, so that the roller 210 can be just axially disposed on the second cross beam 130 in a limited manner without affecting the rolling thereof.

The axes of all the rollers 210 are connected to the bracket 220, and specifically, the bracket 220 includes a plurality of horizontal sections 221 connected to the axes of the rollers 210, a plurality of first vertical sections 222 connected to the other ends of the horizontal sections 221 in a one-to-one correspondence, a plurality of diagonal sections 223 connected to the other ends of the first vertical sections 222 in a one-to-one correspondence, and at least one second vertical section 224 connected to the other ends of all the diagonal sections 223 in a merging manner. The connection between the sections can be detachable connection or integral forging setting. By setting the extension length of the lateral section 221 so that it slightly exceeds the side of the second cross member 130 away from the other end connected to the roller 210, the lengths of the first vertical section 222 and the diagonal section 223 are set so that the top end of the second vertical section 224 away from the ground is slightly lower than the bottom of the second cross member 130. The bracket 220 may be integrally regarded as a structure in which a central support bar, a multi-point auxiliary frame similar to the umbrella frame are scattered along the central axis, the lateral section 221 connected to the roller 210 and the structure contracted to the center of the second vertical section 224 are such that the entire bracket 220 forms a stable structure in which the center of gravity is maintained at the second vertical section 224 under the support of the roller 210. The illuminating portion 300 is connected to the second vertical section 224 on the side near the proximal end. The lighting part is a block structure, which includes a lighting table 320 and a light source 310, the light source 310 is arranged on the lighting table 320, it can be arranged on the surface of the lighting table 320 according to a multi-group arrangement, and also can be arranged inside the lighting table 320, the difference is that if the light source 310 is arranged inside the lighting table 320, the wall or solid filling of the lighting table 320 itself will be made of transparent or light scattering material, similar to the common structural design of fluorescent lamp on the market; if the light source 310 is disposed on the surface of the illumination stage 320, the illumination stage 320 only provides a function of fixing the light source 310. In this design, the light sources 310 are preferably arranged not only on the side of the illumination table 320 close to the ground, but also on the peripheral side thereof parallel to the horizontal plane, so that it is possible to ensure dead-angle-free illumination of the illumination portion and no loss of illumination light.

The driving part 400 for driving the moving part 200 to travel may be provided to include a belt 410, a driving motor 420, and a driving shaft 430 (shown in fig. 3 and 4). The driving belt 410 is closely arranged on the side wall of the vertical beam 120 of the track 100 near the position connected to the second cross beam 130, and the center position thereof is arranged in a manner corresponding to the horizontal position of the central axis of the roller 210, and the whole path length and the trend of the driving belt 410 are the same as those of the track 100. The belt 410 is connected to a driving shaft 430, and the driving shaft 430 has a substantially rod-shaped structure, and the other end thereof is connected to the axis of the roller 210. The belts 410 are connected together at the ends and ends extending along the track 100 to form a closed loop, and a part of the closed loop is sleeved on the driving shaft 430 of the driving motor 420 to form a structure similar to a belt transmission. Under the rotation driving of the driving motor 420, the driving belt 410 moves on the track 100, so that the driving shaft 430 drives the roller 210 to roll, the transverse section 221 of the bracket 220 is connected to the other end axle of the roller 210 and is configured not to rotate along with the roller 210, and the specific structure thereof may be that the transverse section 221 is connected to a fixed side plate shell provided with a rolling bearing, and the rolling bearing rolls along with the roller 210, but the side plate shell does not rotate.

Therefore, the moving part 200 drives the illumination part 300 to move on the track 100, and light can be irradiated to the plants in each cultivation area along with the advance of the movement time according to the preset track 100 route, so that a large amount of fixed illumination construction cost, electricity charge maintenance cost and other consumption cost can be saved. Preferably, in order to realize the light irradiation to the whole plant leaves as omnidirectionally as possible, a telescopic assembly 230 is further disposed on the support 220 of the moving part 200, the telescopic assembly 230 at least includes a telescopic motor 231 and a telescopic rod, in this embodiment, the telescopic rod can be replaced by the second vertical section 224, the telescopic motor 231 can basically adopt the structural design of the existing motor and bearing on the market, and a structure similar to the IP1200 electric push rod can be selected as a reference embodiment. The telescopic motor 231 has one end connected to each diagonal section 223 and the other end connected to the second vertical section 224. Therefore, the freedom of movement of the illuminating part 300 in the vertical and ground directions is formed, when a user needs or is under preset automatic control, the telescopic assembly 230 is opened and moves the illuminating part 300 to a position close to the ground, preferably, the top side of the illuminating part 300 away from the ground is also provided with the light source 310, so that the light source 310 can irradiate the back of the plant leaf, and the effect of irradiating the leaf in all directions is achieved.

At present, for a common cultivation place 500 on the market, plants are cultivated basically by utilizing a soilless cultivation mode or a soil cultivation mode, the soilless cultivation generally uses a medium serving as soil and a certain nutrient solution as a substrate for cultivating the plants, wherein the medium can be selected from various types, such as wood chips, plant ash, gravel, cotton seed shells, vinasse and other solid powder or pressed brick-shaped solid materials, and the materials basically have the characteristics of strong water retention and a large number of loose pores, and simulate the loose and porous structure of the soil as much as possible. While soil cultivation is more traditional, i.e. using real soil or soil transferred from the field as the substrate for plant cultivation. Both the traditional soil cultivation mode and the novel soilless cultivation mode are used for planting plants, and the substrates used for planting the plants contain microorganisms with different quantities and types. For example, the main body of the biological group in the medium for soilless culture mostly takes bacteria as the main body, less accounts for bacteria microorganisms such as fungi, actinomycetes and molds, and different medium selections may cause the environment for plant cultivation to contain different kinds and quantities of strains, some of which are generated during medium preparation, for example, the medium obtained after some organic matters are decomposed and ripened contains a large amount of microbial strains, and other mediums obtained after aseptic treatment are brought into the environment where the root system of the plant is located from the outside due to operations such as planting, fertilizing and trimming. Research shows that microorganisms play an important role in the process of absorbing nutrients in a substrate by plants, chemical elements beneficial to the plants in the substrate, such as nitrogen, phosphorus and potassium ions, can be converted into a form which is easier to be absorbed by the plants through the metabolic process of the microorganisms, and although the microorganisms account for a small part of the total mass of the substrate, the active energy provided by the microorganisms and the effective fertility provided by the plants account for a considerable part of the total fertility provided by the substrate. It can be seen that the content of microorganisms in the substrate, or the resulting fertility beneficial to the plant, which can be expressed in terms of the amount of carbon in the microorganism, has a considerable effect on the overall plant cultivation process. The carbon content of the microorganisms is the sum of the carbon in living and dead microorganisms with the volume of less than 5000 cubic microns in the medium, which is an active part in an organic matter part in the medium and is most active in the medium, and is a source for providing a large amount of effective fertility for plants, so that the numerical value of the carbon content of the microorganisms has a great influence on the growth effect of the plants planted in the medium under the condition that other conditions are relatively fixed.

The microorganisms in the medium are very susceptible to the influence of the environment factors of the substrate, such as nitrogen fertilizer supply, EC (conductivity), pH, salt concentration, oxygen and carbon dioxide content, alternation of wetting and drying, different fertilization systems, root exudates and the like all can influence the types and the vitality of the microorganisms. The above-mentioned rational selection of the environmental factors and the selection of the cultivation sites 500 or cultivation facilities with a constant environment can be made in a relatively stable state, in the case that these environmental factors are relatively stable, another environmental factor having a certain influence on the carbon content of the microorganisms is the light, on one hand, because in the case of partial cultivation, the user can add photosynthetic bacteria to the medium as a means for assisting in regulating the state of the medium, the carbon content of the microorganisms of the photosynthetic bacteria has a greater relation to the light conditions, on the other hand, there are studies showing that most of the non-photosynthetic bacteria beneficial to the growth of plants also have a forward relation to the carbon content of the microorganisms under the direct or indirect influence of the light. Therefore, the improved medium which utilizes proper light to positively guide the propagation of the microorganisms in the medium to obtain more microorganisms with higher carbon content becomes a better means for optimizing the composition of active substances of the medium, improving the quality of the growing environment of the plants in the medium and keeping the excellent growth of the plants. Firstly, the conventional scheme is to regularly deliver a cultured medium containing a large amount of high-quality microorganisms into a medium where the plants are located as a fertilizer, the process firstly needs a large amount of input of external labor force, and in addition, the filling of the external fertilizer can cause the original environment where the plants are located to be suddenly changed, so that the plants are not tolerant and grow and are damaged; secondly, if a place for cultivating microorganisms is separately divided in the plant cultivating place 500 and the above-mentioned proposed moving part 200 drives the light irradiation part 300 to move and irradiate the microorganisms and the light irradiation to the plants are performed, since the lighting conditions required for the growth of microorganisms and the growth of plants are different in most cases, taking illumination and time conditions as examples, experiments show that under certain research environments, the carbon content of microorganisms in a medium is obviously increased under the irradiation of 1000 lux and 10000 lux for 1 hour, but for plants, even plants with the shortest photoperiod require several hours of irradiation, and for plants with different photoperiods, for example, the illumination intensity required by positive plants and negative plants is various, and is different from the value of 1000 or 10000 lux required for the growth of the microorganisms; finally, it is also a problem how a medium grown at the microorganism growing site 500 containing a large amount of microorganisms can migrate into the medium in which the plants are grown to achieve improved optimization of the medium in which the plants are grown.

Therefore, the invention provides an embodiment of microorganism-participation-based optimized modification of a medium in which a plant is located under mobile illumination guidance by utilizing a mobile light source to cultivate microorganisms and guiding the microorganisms to uniformly migrate to the irradiated plant soil while irradiating the plant.

The cultivation site 500 in the present embodiment is divided into a microorganism cultivation area 510 and a planting area 520, wherein the planting area 520 is disposed around the microorganism cultivation area 510 in a surrounding manner. For example, if the microorganism cultivation area 510 and the planting area 520 are divided into squares, the cultivation site 500 may be divided into a structure similar to a squared figure, with the microorganism cultivation area in the central grid and the planting area 520 in other grids surrounding the central grid. The trajectory 100 sequentially passes through the surrounding planting area 520 and is radially tapered to a surrounding radius to be positioned close to the microorganism culture area 510 at the surrounding center. Conversely, it can be understood that the path of the moving part 200 defined by the locus 100 is set to spirally and outwardly surround the center point of the microorganism cultivating region 510 as a reference point and pass through at least all the planting regions 520 located at the outside, as shown in fig. 2. The spiral-type winding path may be a winding shape in the form of a standard spiral line, and may also include some non-standard spiral types, such as a zigzag structure, and the track 100, in which the connection length between a certain point on the track 100 and the reference point increases continuously or in steps during the process of moving along the track 100 away from and around the reference point, may be regarded as the spiral-type winding path. The medium of the planting region 520 and the microorganism-cultivating region 510 is in a state of being in contact with each other to facilitate the migration of microorganisms, no plants are planted in the microorganism-cultivating region 510, and plants desired by a user are planted in the planting region 520. By referring to the end of the track 100 adjacent to the microorganism cultivation area 510 as the first end 170 and the other end of the track on or outside of a certain planting area 520 as the second end 180, it can be seen that the first end 170 is located at the surrounding center of the track 100 and the second end 180 is located at the surrounding periphery of the track 100. The portion of the trajectory 100 falling on the microorganism-cultivating region 510 is referred to as a first paragraph 150, and correspondingly, the portion of the trajectory 100 falling on the outer-surrounding planting region 520 is referred to as a second paragraph 160. The initial point of the moving part 200 moving on the track 100 is set on the first end 170, and the moving part 200 is driven by the driving part to make a circling motion with a gradually increasing radius along the track 100. Here, the time elapsed while it moves in the first session 150 is referred to as a first time, the time while it moves in the second session 160 is referred to as a second time, and the illuminance of the illumination used by the illumination section 300 provided thereon in the first session 150 is referred to as a first illuminance, and the illuminance of the illumination used in the second session 160 is referred to as a second illuminance. As can be seen from the structure of the track 100, when the moving part 200 moves at a constant speed, since the path length of the first section 150 is shorter than the path length of the second section 160, the first time is shorter than the second time, and the carbon content of the microorganism can be significantly increased by the short-time irradiation, and the structural design of the track 100 perfectly matches the requirements of the short irradiation time of the microorganism cultivation area 510 and the long irradiation time of the planting area 520. In addition, the first illumination and the second illumination are set differently according to different requirements of microorganism cultivation and plant cultivation, so that the first illumination can better promote breeding of microorganisms, and the second illumination can better promote growth of plants. The microorganism cultivation area 510 is not planted with plants, so that microorganisms in the medium can propagate under the irradiation of the structured light to the maximum extent, and when the illumination portion 300 gradually moves from the first section 150 to the second section 160 in a surrounding manner along with the moving portion 200 on the track 100, due to the phototaxis of most microorganisms, the microorganisms are guided and migrated into the cultivation area 520 in a surrounding manner. The photosynthetic bacteria microorganism needs illumination as an energy source for growth and propagation, and has a certain phototaxis for part of non-photosynthetic bacteria, because the phototaxis is an active selection characteristic for the bacteria, and the phototaxis can lead the bacteria to enter an area with sufficient light conditions for growth and propagation through photosensitive protein in the bacteria. The spiral surrounding arrangement of the track 100 enables the microorganisms to propagate and expand outward in a ring surrounding manner gradually along with the movement of the light, that is, the area of the medium covered by the high-level microorganism carbon amount is also concomitantly expanded outward in a spiral manner, and the covering of the medium by the high-level microorganism carbon amount refers to a process of covering the area of the medium with the low-level microorganism carbon amount originally by the increased area of the microorganism carbon amount caused by the movement of the light in the medium area with the low microorganism carbon amount in the total planting area 520. Compared with unidirectional guiding, the microbial propagation direction is remarkably increased through the circumferential light guiding, the omnidirectional propagation direction can be achieved, and the coverage efficiency of the microbial propagation under the light guiding on the planting area 520 is improved. In addition, the method has the advantages that the medium in which the plants in the planting area 520 under the irradiation of the light just migrate into a large number of beneficial microorganisms due to the guidance of the light, the carbon content of the microorganisms in the medium is gradually increased along with the lapse of time, the metabolic process of the microorganisms is used for modifying and optimizing the medium in which the part of the plants are located, the medium is just matched with the plant photosynthesis performed at the same time, the plant growth conditions are further optimized and upgraded, and the quality of the crops is further improved by correspondingly and dynamically adjusting the carbon content of the microorganisms in the medium in which the plants are located during the plant photosynthesis.

Preferably, by adjusting the driving speed of the driving part, a first time when the moving part 200 moves in the first paragraph 150 and a second time when it moves in the second paragraph 160 may be adjusted. Further, different or the same driving speed may be set according to different microorganism species and plant species selected by the user to obtain different or the same first time and second time, and the same or different first illuminance and second illuminance of the illumination part 300 in two paragraphs may be set to achieve the optimal illumination time and illumination intensity for the microorganism cultivation and the plant cultivation, respectively. That is, the moving part 200 and/or the illuminating part 300 adjusts the moving parameter and/or the illumination parameter passing through the cultivation area and/or the planting area 520 according to the microorganism growth parameter and/or the plant growth parameter. The microorganism growth parameters may include the type of microorganism, the optimal illumination intensity, light quality, illumination time and other parameters required by the microorganism of the type, and the plant growth parameters are substantially similar to those of the microorganism, and the two parameters may be further determined according to the microorganism and the plant to be used, and the process of determining the parameters may be completed by a limited number of experiments of controlling the variables. Accordingly, the movement parameter refers to a movement time designed according to the two parameters, for example, the movement time includes the first time and the second time, or a movement speed, a dead time, and the like, and the illumination parameter refers to a light quality, a light intensity, a light spectrum, and the like, which are changed according to the two growth parameters. The basis for the speed change of the driving portion may be a sensing signal generated from the timing when the moving portion 200 passes through the first segment 150 and enters the second segment 160, and the sensing signal may be generated by a sensor disposed on the track 100. The sensing signal can be used as the basis for the conversion of the driving speed and the illumination intensity at the same time.

Preferably, when the illumination part moves along the track, as the plants growing in a large amount and having higher plants enter the planting area from the microorganism cultivation area, the leaves of the plants can shield part of the light penetrating from the upper part, and the light guiding capability to the microorganisms can be weakened slightly, so that the embodiment also provides a scheme for guiding the movement of the microorganisms and realizing the photosynthesis growth of the plants with high level by using the high-light-intensity narrow-band light source in a matching way. Specifically, the light source included in the illumination portion of the present embodiment is formed by a light emitting component with a small illumination range and high light intensity, such as a component structure like an LED spotlight, and a plurality of light sources that can work individually or jointly can be arranged in series in a straight line to form a structure similar to a light bar. Studies have shown that short duration illumination with narrow band high intensity is more beneficial to the illuminated plant to quickly reach an optimal photosynthetic level, which in some cases can be considered as the point of maximum light saturation, relative to illumination modes that employ a broad-range flood light source for a long duration. In addition, compared with a floodlight source, the narrow-band high-light-intensity irradiation range is reduced, but in the irradiation range, the irradiation dead angle is reduced correspondingly due to the high light intensity, and the photosynthesis level can be improved for the part of the plant which usually does not receive light. Furthermore, from the microcosmic level, cilia covered on the plant leaves also have certain influence on the irradiation of light, and the design of adopting narrow-band high light intensity enables the shielding influence of the cilia to be also obviously reduced, and from the backlight surface of the leaves, chloroplasts on the blades can receive the light transmitted from the front of the leaves, so that more opportunities of photosynthesis can be obtained, and the growth uniformity of the light facing surface and the backlight surface of the plant leaves can be improved. Adopt mobilizable narrowband high intensity light source still has an advantage that it will produce a large amount and can see through the light that the blade sheltered from, and these light see through sheltering from of blade, still can produce the higher illumination of level in the soil or the basement that the plant belongs to, are favorable to promoting the CD-ROM guide to microorganism in the soil, are favorable to being in the growth level further promotion of microorganism in the environment that the plant under illumination belonged to, then drive microorganism carbon content in the soil further promotion. When plants are used in photosynthesis, the plants synthesize organic matters required by the growth of the plants by using light energy, in the process, the roots absorb inorganic matters from soil or a substrate as element sources necessary for the growth, generally more importantly, nitrogen, phosphorus and potassium elements, the plants convert a large amount of inorganic matters contained in the plants into organic matters helpful for the growth through photosynthesis, and meanwhile, the plants absorb more inorganic matters from the soil or the substrate through the roots. Therefore, the carbon content of microorganisms in soil or a substrate where the irradiated plants are located can be promoted by the photoconductive migration of the microorganisms through the narrow-band short-time high-light-intensity irradiation, the photosynthetic level of the plants is promoted rapidly, the process that the plants absorb inorganic matters from the soil with high inorganic matter content to be used as raw materials to promote photosynthesis to generate organic matters is facilitated, and the planting effect with better growth state and higher yield is finally obtained.

Preferably, according to the light intensity, the plant species and the microorganism species, a microorganism-related illumination database can be established in a mode of year-round experiment and experience accumulation, and the database can be stored in the electronic equipment in a virtual form. Specifically, different microorganism species have different growth influences under the parameters of light intensity, irradiation time, light wavelength and the like, the modification capability of the microorganism species on soil or a substrate is different, the proportion of inorganic matter elements required by plants generated in the modification process is different, the influence of the light intensity on the photosynthesis level of different plants is different, the influence of different light parameters on the same plant is also different, the different parameters are selected as fixed parameters, the other parameters are used as variables, the result obtained by combining the fixed parameters and the variables is put into a microorganism-related illumination database through the modes of experiments, scientific derivation and the like, corresponding contents can be searched from the database during subsequent plant production, and the optimal proportion of microorganisms and light of the currently planted species can be conveniently obtained.
