Description

Smart seedling system capable of producing fruit and vegetable seedlings without damage from pests and diseases include viruses}

The present invention relates to a smart seedling system capable of producing fruit and vegetable seedlings without damage from pests and viruses.

Recently, as plant factory research has been actively conducted as an alternative to the deterioration of the agricultural environment such as extreme weather and the demand for future agricultural technology, securing economic feasibility, such as initial investment and operating costs, has become an important requirement.

To this end, interest in the advancement of plant factory-related element technologies and the preoccupation of high value-added technologies through research on the basic technology for stable production of plants is increasing.

For example, the seedling process of a plant factory refers to all processes of sowing seeds in a cultivation space isolated from the external environment and then raising them into young plants suitable for transplanting to the main cultivation place.

In order to carry out this seedling process, nutrient solution and light are supplied, but there is a problem in that the growth environment of the seedlings is not constant for all seedlings because the supply of light is not constant. In addition, in the supply of the nutrient solution, it is necessary to supply and drain the nutrient solution more precisely by simply supplying and draining the nutrient solution using a timer.

In addition, the upper and lower temperatures of the cultivation space where the seedling process of the plant factory takes place are different, and the cumulative heat of the light emitting member generated by irradiating the seedling plate with light is generated higher in the center of the seedling plate than the surrounding area, creating an overall uneven temperature and humidity environment. There was a problem that the growth status of the seedlings was uneven. This problem occurred because the seedlings cultivated on the seedling plate were exposed to different growth environments, resulting in irregular cultivation.

In addition, in the process of raising seedlings exposed to the external environment, growth regulators and pesticides are used to prevent pest viruses as cultivation is performed in a state exposed to pest viruses, but growth regulators and pesticides do not harm seedlings. It is only protected from bias, but it acts as a cause of accelerating aging, and there is a problem in that production is reduced.

Advantages and features of the present invention, and methods of achieving them, will become clear with reference to the detailed description of the following embodiments taken in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only these embodiments make the disclosure of the present invention complete, and common knowledge in the art to which the present invention belongs. It is provided to completely inform the person who has the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numbers designate like elements throughout the specification.

Hereinafter, the present invention will be described with reference to drawings for explaining a smart seedling system capable of producing fruit and vegetable seedlings without damage from pests and viruses according to embodiments of the present invention.

Referring to FIG. 1, the smart seedling system capable of producing fruit and vegetable seedlings without damage from pests and viruses according to the present invention includes a frame 10, a nutrient solution plate 20, a seedling plate 30, a nutrient solution supply unit 40, and a light supply unit 50 ) and a control unit 60.

First, the frame 10 is made of steel and is installed so that a plurality of nutrient solution plates 20 to be described later can be stacked vertically.

In addition, the frame 10 is installed in a cultivation chamber 80 having a cultivation space 81 that is partitioned from the outside and sealed.

The nutrient solution plate 20 is provided on the frame 10 . At this time, a plurality of nutrient solution plates 20 may be provided up and down, and may be provided spaced apart from each other by the frame 10 .

In addition, the nutrient solution plate 20 is coupled to the nutrient solution supply unit 40 so that the nutrient solution can be filled and drained by the nutrient solution supply unit 40 to be described later.

In addition, the nutrient solution plate 20 may have a grid-patterned flow path formed on the bottom surface. This is to allow the nutrient solution to spread throughout the lower surface of the nutrient solution plate 20 through the flow path, regardless of the seedling plate 30 provided, since a seedling plate 30 to be described later is provided inside the nutrient solution plate 20. In addition, when the nutrient solution is drained, it can be easily drained through the flow path.

In particular, since the upper end of the nutrient solution supply pipe 42 of the nutrient solution supply unit 40, which will be described later, passes through the lower surface of the nutrient solution plate 20 and communicates with it, and is an inlet for nutrient solution supply as well as nutrient solution drainage, the flow path is the nutrient solution supply pipe ( 42) may be inclined. That is, when the nutrient solution is drained, the nutrient solution may be moved to the upper end of the nutrient solution supply pipe 42 by the inclined passage and drained.

The seedling plate 30 is provided on the nutrient solution plate 20 so that seedlings can be grown. At this time, the seedling plate 30 may be formed of a tray with ports in which a plurality of seedlings can be grown. In addition, a plurality of seedling plates 30 may be provided in the nutrient solution plate 20 according to the size of the nutrient solution plate 20 .

In addition, the seedling plate 30 may have a plurality of through holes formed in the pot so that the nutrient solution filled in the nutrient solution plate 20 can be absorbed into the soil.

The nutrient solution supply unit 40 supplies nutrient solution to the nutrient solution plate 20 and drains the supplied nutrient solution.

The light supply unit 50 supplies light to the seedling plate 30.

The controller 60 controls the nutrient solution supply unit 40 and the light supply unit 50 to supply the nutrient solution and light according to preset values.

Meanwhile, referring to FIGS. 2 to 4, the nutrient solution supply unit 40 will be described in detail. The nutrient solution supply unit 40 includes a nutrient solution tank 41, a nutrient solution supply pipe 42, an overflow pipe 43, and a nutrient solution drain pipe. (44), a nutrient solution pump (45), and a weight measuring unit (46).

The nutrient solution tank 41 stores the nutrient solution and may be provided at the lower part of the frame 10, but is not limited thereto.

The nutrient solution supply pipe 42 passes through the nutrient solution tank 41 and the lower surface of the seedling plate 30 to communicate with each other.

That is, the nutrient solution flows into the nutrient solution plate 20 from the bottom through the upper end of the nutrient solution supply pipe 42 . The introduced nutrient solution spreads throughout the nutrient solution plate 20 along the flow path and gradually fills up.

The overflow pipe 43 has one end provided at a set position higher than the bottom surface of the seedling plate 30, communicates with the nutrient solution tank 41, and drains the nutrient solution supplied more than the set position to the nutrient solution tank 41.

At this time, the setting position of the overflow pipe 43 is preferably located lower than the upper end of the seedling plate 30, but is not limited thereto.

As such, the nutrient solution circulates through the nutrient solution supply pipe 42 and the overflow pipe 43 through the nutrient solution tank and the nutrient solution plate 20, and during the circulation of the nutrient solution, the nutrient solution plate 20 is filled with a certain amount of nutrient solution and soil will be absorbed into

The nutrient solution drainage pipe 44 connects the upper portion of the nutrient solution supply pipe 42 and the overflow pipe 43.

The nutrient solution pump 45 supplies the nutrient solution stored in the nutrient solution tank 41 to the nutrient solution supply pipe 42.

At this time, the nutrient solution drain pipe 44 is formed smaller in diameter than the nutrient solution supply pipe 42.

Accordingly, the nutrient solution supplied to the nutrient solution pump 45 is moved only through the nutrient solution supply pipe 42 and is supplied to the nutrient solution plate 20 .

In addition, when the nutrient solution pump 45 is stopped, the nutrient solution is drained from the nutrient solution plate 20 through the nutrient solution supply pipe 42 according to the principle of a siphon, and at the same time, the nutrient solution drain pipe 44 communicates with the empty overflow pipe 43 ) through the overflow pipe 43. And, when all the nutrient solution is drained from the nutrient solution plate 20, the nutrient solution remaining in the nutrient solution supply pipe 42 is moved to the nutrient solution tank 41.

The weight measuring unit 46 measures the weight of the seedling plate 30, which changes according to the nutrient solution supplied to the seedling plate 30, in real time.

At this time, the control unit 60 operates the nutrient solution pump 45 to supply and circulate the nutrient solution to the seedling plate 30 for a first preset time, and the weight of the seedling plate 30 measured by the weight measuring unit 46 is When it is smaller than the preset set weight value, the nutrient solution pump 45 is operated again for the first time.

That is, the control unit 60 controls the nutrient solution pump 45 as the weight measuring unit 46 detects the weight to be measured. In other words, the control unit 60 measures the initial weight of the nutrient solution plate 20 that is stabilized without changing after the nutrient solution pump 45 is stopped and all of the nutrient solution is drained from the nutrient solution plate 20 . When the nutrient solution absorbed in the soil evaporates, the weight of the nutrient solution plate 20 becomes smaller than the initial weight value. At this time, when the initial weight value reaches the set weight value, the control unit 60 operates the nutrient solution pump 45 again so that the nutrient solution is absorbed into the soil.

In addition, the controller 60 stops the operation of the nutrient solution pump 45 from 3 days before the second time when the transfer of the seedling is set. This affects the rooting of the seedlings by stopping the supply of the nutrient solution, and the seedlings at the second time of transfer are well separated from the seedling plate 30.

5 to 7 , the light supply unit 50 includes a position control bar 52, a lighting tube 70, a light emitting member 55, and a distance measurement unit 56.

The position control bar 52 is spaced apart from the seedling plate 30 and is provided at an upper portion, and has a sliding groove 51 formed in the longitudinal direction. For example, the position control bar 52 has a sliding groove 51 inserted into the lower side thereof, and is provided in the longitudinal direction of the nutrient solution plate 20 . That is, the longitudinal direction of the positioning bar 52 and the nutrient solution plate 20 is provided to be horizontal.

The lighting tube 70 is coupled to the sliding groove 51 at the top and has a sliding protrusion 53 that can slide in the longitudinal direction of the positioning bar 52, and is perpendicular to the longitudinal direction of the positioning bar 52. It is provided on the position control bar 52. That is, the lighting tube 70 is provided so that the width direction of the nutrient solution plate 20 and the longitudinal direction of the lighting tube 70 are horizontal.

The light emitting member 55 is provided inside the lighting tube 70 . At this time, the light emitting member 55 may be made of an LED, but is not limited thereto. In addition, the light emitting member 55 can control the amount of light supplied to the seedlings by adjusting the intensity of light.

The distance measuring unit 56 measures the distance between the upper leaf of the seedling grown on the seedling plate 30 and the light emitting member 55 .

At this time, the control unit 60 adjusts the preset light intensity according to the distance measured by the distance measurement unit 56, but increases the light intensity as the distance between the upper leaf of the seedling and the light emitting member 55 decreases. Decrease. This is to constantly adjust the intensity of light, that is, the amount of light.

In particular, when the initial amount of light at which seedlings start to develop is the same when the seedlings grow and grow in size, a phenomenon in which leaves are burned due to unnecessary light supply occurs. Therefore, since the control unit 60 reduces the light intensity (light amount) as the distance between the light emitting member 55 and the leaves of the seedlings gets closer, a constant amount of light is supplied to the seedlings during the seedling period, thereby creating an environment optimal for growth. to keep

On the other hand, the lighting tube 70 is provided with a plurality of light emitting members 55, and is provided with a plurality of spaced apart in the longitudinal direction of the nutrient solution plate 20.

At this time, the lighting tubes 70 are slidable along the longitudinal direction of the positioning bar 52, so that a plurality of lighting tubes 70 are spaced apart from each other, but are spaced from the center of the nutrient solution plate 20 toward the outside. It is preferable that the distance to be provided is shortened, but is not limited thereto.

That is, when the light emitting members 55 are spaced apart from each other at regular intervals, heat generated from the light emitting members 55 is accumulated so that the central heat of the nutrient solution plate 20 is higher than that of the outer portion of the nutrient solution plate 20 . This phenomenon causes uneven growth of the seedlings because it is impossible to create a growth environment that provides the same temperature, humidity, and amount of light to all the seedlings grown on the nutrient solution plate 20.

To this end, the lighting tubes 70 are spaced apart from each other in the center of the nutrient solution plate 20 to reduce the amount of heat and light accumulated, and the amount of heat and light accumulated by spacing the lighting tubes 70 narrower toward the outer portion of the nutrient solution plate 20. The amount of light and the temperature and humidity supplied to the nutrient solution plate 20 as a whole can be supplied equally by increasing .

In addition, the lighting tube 70 includes a fixing member 74 and a cover 77.

In the fixing member 74, the first concave groove 71 is formed in the longitudinal direction, and a plurality of fixing grooves 72 in which the light emitting member 55 can be respectively provided are formed in succession in the first concave groove 71, A plurality of fixing protrusions 73 are formed at both upper ends of the first concave groove 71 .

In the cover 77, a second concave groove 75 is formed in the longitudinal direction, and fitting coupling grooves 76 into which fixing protrusions 73 are fitted are formed at both lower ends of the second concave groove 75, , The first concave groove 71 and the second concave groove 75 are coupled face to face by the combination of the fixing protrusion 73 and the fitting coupling groove 76. In addition, the cover 77 is formed with a sliding protrusion 53 at the top.

At this time, the wiring connected to the light emitting member 55 and the power supply unit can be protected by being provided in the passage 78 formed by the first concave groove 71 and the second concave groove 75 facing each other.

In this way, by fixing each light emitting member 55 to the fixing groove 72, the light emitting members 55 can be arranged at regular intervals while being fixed.

In addition, since the lighting tube 70 can be separated into the fixing member 74 and the cover 77, the light emitting member 55 can be easily fixed to the fixing member 74 from which the cover 77 is separated, and the light emitting member 55 can be easily fixed. The lighting tube 70 is completed by covering and combining the cover 77 with the fixing member 74 in a state where all members 55 are installed. In addition, when the position of the light emitting member 55 needs to be moved when measuring accumulated heat according to light, the position of the light emitting member 55 can be easily separated by removing the cover 77 to correct the position of the light emitting member 55 .

Here, the lighting tube 70 can be coupled by sliding the cover 77 in the longitudinal direction, but due to the constant length of the lighting tube 70, the wiring must be moved along with the sliding and unnecessary wiring is required, causing inconvenience. do. In addition, one end of the cover 77 is connected to one end of the fixing member 74, and an opening method through rotation of the cover 77 is also possible, but in a state where the cover 77 is already coupled to the positioning bar 52 Discomfort in opening occurs through rotation.

That is, when position correction according to temperature is required in a state in which all light emitting members 55 are installed, the fixing protrusion 73 and the fitting coupling are made so that the fixing member 74 and the cover 77 can be easily separated and combined. The fitting method of the groove 76 is preferable, but is not limited thereto.

In addition, as described above, in order to even out the accumulated heat and light amount of the light emitting member 55, the light emitting member 55 is provided in the fixing groove 72 and is spaced apart from the center of the light tube 70 toward the outer portion. It is preferable that the number of fixing grooves 72 is reduced and densely provided toward the outer portion of the nutrient solution plate 20 in the longitudinal and width directions, but is not limited thereto.

That is, it is possible to minimize the temperature of light accumulated in the center of the nutrient solution plate 20 and to irradiate uniform light to all seedlings grown on one or more seedling plates 30 provided in the nutrient solution plate 20.

On the other hand, referring to FIG. 8 , the smart seedling system capable of producing fruit and vegetable seedlings without pest and disease virus damage according to the present invention further includes an air conditioning unit 90.

The air conditioner 90 may circulate air in the cultivation space 81 of the cultivation chamber 80 up and down under the control of the controller 60 .

The air conditioner 90 includes a first circulation fan 91 , a second circulation fan 92 , an air diffusion plate 93 and a visible light sterilization unit 94 .

The first circulation fan 91 is provided above the cultivation space 81 and is provided above the central portion of the nutrient solution plate 20, and sucks in air from the bottom and discharges it to the top.

The second circulation fan 92 is provided at the bottom of the cultivation space 81 and is provided on the outer side of the nutrient solution plate 20, sucks in air from the bottom and discharges it to the top.

In this way, the first circulation fan 91 and the second circulation fan 92 circulate the air in the inner space of the cultivation room 80 up and down, so that the top and bottom temperatures of the cultivation room 81 can be maintained the same and constant. have.

Here, temperature measuring units capable of measuring temperatures may be provided at the upper and lower portions of the cultivation space 81 .

The control unit 60 operates the first circulation fan 91 and the second circulation fan 92 when the average temperature difference between the top and bottom of the cultivation space 81 measured by the temperature measurement unit is equal to or greater than a preset temperature difference value. and when the temperature difference is less than the value, the operation of the first circulation fan 91 and the second circulation fan 92 may be stopped.

As a result, the same growth environment is maintained for all seedlings grown on the vertically stacked seedling plates 30 by circulating the cold air and warm air in the cultivation space 81 without being stagnant in one place so that a constant temperature is maintained regardless of the height. And seedlings with the same growth conditions can be grown.

The air diffusion plate 93 is provided on the upper part of the first circulation fan 91 and is inclined downward toward the outside from the central portion, so that air can be diffused downward and outward.

The visible light sterilization unit 94 is provided below the second circulation fan 92 and can sterilize by irradiating visible light of 400 to 410 nm with the air sucked by the second circulation fan 92 .

At this time, the visible light sterilization unit 94 is irradiated with visible light toward the bottom of the cultivation space 81, so that the seedlings are not affected.

[Experimental example]

The cumulative yields of the cucumber seedlings of Example and the cucumber seedlings of Comparative Example were compared up to the 64th day.

After transfer and planting, cucumbers began to be harvested from the comparative example cucumber seedlings on the 20th day, and cucumbers began to be harvested from the example cucumber seedlings on the 26th day. As time passed, the yield began to increase, but from the 34th day, the cumulative yield of cucumbers harvested from the cucumber seedlings of the Example began to increase more than that of the cucumber seedlings of the comparative example.

In addition, when examining the development state (stem length, etc.) with the naked eye, the cucumber seedlings of Example were better than the cucumber seedlings of Comparative Example. In addition to being observed, aging and pest virus damage began to occur first in the cucumber seedlings of the comparative example, and a change occurred in the yield.

The cumulative yield up to 64 days was 450 kg in the cucumber seedlings of Example and 355 kg in the cucumber seedlings of Comparative Example, resulting in a difference of 95 kg.
