Description

Plant cultivation method and plant cultivation system

The present invention is a plant cultivation method and a plant cultivation system applied when plants are hydroponically cultivated in a so-called "plant factory" where leafy vegetables and the like are systematically produced in a closed or semi-closed space. Regarding.

When hydroponically cultivating plants such as leafy vegetables in a plant factory, in order to increase the cultivation volumetric efficiency, for example, a pot that supports the plant is inserted and the pitch of the holes that can be supported is changed according to the growth degree of the plant. A cultivation method has been adopted in which a plurality of floats are prepared and the plants supported by the pots are transplanted from a float having a small hole pitch to a float having a large hole pitch as the plant grows (see, for example, Patent Document 1).

However, the cultivation method as disclosed in Patent Document 1 has a problem that not only it takes a lot of time and effort for transplanting, but also the plant is damaged at the time of transplanting, and the plant grows poorly and grows poorly after transplanting.

As a method for cultivating a plant to improve the above problem, the main body comprises a plastic main body having a holding for holding the plant and a guide portion integrally molded with the holding portion, and a nutrient solution storage container such as a PET bottle. A bottle-type hydroponic cultivation method (see, for example, Patent Document 2) using a hydroponic cultivation tool in which a guide portion of the above is fitted to the mouth of a nutrient solution storage container has been proposed. In addition to that, by arranging a plurality of plant nurseries suspended in the suspension portion in the horizontal direction and transporting the plurality of plant nurseries in a predetermined horizontal direction according to the growth of the plant, each plant nursery A hydroponic cultivation system with an interval adjusting mechanism (see, for example, Patent Document 3) has been proposed in which cultivation is performed while gradually or continuously increasing the interval.

However, in the case of the bottle-type hydroponic cultivation method of Patent Document 2, as compared with the cultivation method of Patent Document 1, there is no need for transplantation, and subsequent poor growth and poor growth due to damage to the plant can be suppressed. Although it is possible, it is necessary to adjust the spacing between a plurality of plants based on visual observation, which requires time and effort, and there is a problem that it is difficult to adjust the spacing to match the growth of plants.

Further, in the case of the hydroponic cultivation system with an interval adjustment mechanism of Patent Document 3, the interval of the plant nursery can be changed mechanically easily and quickly, and the labor of transplantation is less than that of the cultivation method of Patent Document 1. It is unnecessary, and while it is possible to suppress poor growth and poor growth due to damage to the plant, the system configuration tends to be complicated and expensive, and the interval adjustment operation that matches the growth of the plant Further, there is a problem that maintenance such as cleaning of the suspension part of the plant nursery or the constituent members of the interval adjusting mechanism requires a great deal of labor and cost.

Further, as in Patent Documents 2 and 3, the cultivation method and cultivation system for adjusting the cultivation pitch (interval) of the plant according to the growth are different depending on the time of growth, and the result is that the plant is large or small. As a result, it is cultivated in a wide area, high volumetric efficiency cannot be obtained, and if a disease or poor growth occurs during cultivation, it is necessary to deal with it and set high quality cultivation conditions. There was also the problem of difficulty.

The present invention has been made in view of the above-mentioned circumstances, and not only reduces the labor for transplantation and damage to the plant, but also increases the volumetric efficiency, and the interval can be adjusted according to the growth of the plant, so that the cultivation is of good quality. It is an object of the present invention to provide a plant cultivation method and a plant cultivation system from which conditions can be obtained.

In order to achieve the above object, the method for cultivating a plant according to the present invention is a method for cultivating a plant in which a plurality of media are juxtaposed at predetermined intervals and the plant is kept in the medium and cultivated. It is characterized in that it includes a step of measuring the size of the plant and a step of adjusting the adjacent interval of the plant or the medium according to the measurement result of the size every predetermined number of cultivation days.

Further, the plant cultivation system according to the present invention is a plant cultivation system for growing and cultivating a plant held in a medium in a state where a plurality of media are juxtaposed at predetermined intervals, and every predetermined cultivation day elapses. It is characterized in that it is provided with a dimensional measuring means for measuring the size of a plant and an interval adjusting means for adjusting the adjacent spacing of the plant or the medium according to the dimensional measurement result by the dimensional measuring means.

According to the plant cultivation method and the plant cultivation system according to the present invention having the above-mentioned characteristic composition, the size, specifically, the height and width of the plant are measured every time a predetermined cultivation day elapses, and the plant is measured. By adjusting the horizontal and / and vertical adjacent spacing of the plant or the medium holding the plant according to the measurement result, the leaves of the adjacent plant are ensured with high volume efficiency adapted to the degree of growth of the plant. It is possible to prevent the parts from overlapping and partly becoming a shadow, or to prevent the leaves from rubbing against each other and being damaged, and it is also possible to improve the illumination efficiency by irradiating each plant with light. Therefore, it is possible to always obtain the optimum and high quality cultivation conditions according to the growth degree of the plant.

In the plant cultivation method and the plant cultivation system according to the present invention, it is preferable to adjust the adjacent interval in both the horizontal direction and the vertical direction.
In this case, since the plant grows not only in height but also in width at the same time after the lapse of a predetermined number of cultivation days, the adjacent spacing should be adjusted in both the horizontal direction and the vertical direction according to the measurement result of the dimensions. As a result, it is not necessary to measure the height and the width separately and perform the horizontal interval and the vertical interval separately, and the labor for adjusting the interval can be reduced to the maximum.

Further, in the plant cultivation method and the plant cultivation system according to the present invention, it is preferable to determine the adjustment width of the adjacent interval according to the predicted growth amount of the plant after the time of dimension measurement.
In this case, it is possible to predict the amount of plant growth after the time of dimensional measurement, and adjust the interval between adjacent plants or the medium according to the predicted amount of growth. Therefore, by taking a large interval for measuring the dimensions and adjusting the interval corresponding to the measurement result, it is possible to reduce the labor for cultivation, suppress the formation of shadows due to the overlap of the leaves, and improve the growth of the plant. Can be good.

Further, in the plant cultivation method and the plant cultivation system according to the present invention, it is preferable that the medium or the cup in which the medium is set is given an ID for collecting data of each plant.
In this case, not only can each of a plurality of cultivated individuals (plants) be visually or image-processed, but also the growth of each cultivated plant in each cultivation process can be individually measured using the ID, and the plant can be recognized. It can also be effectively used for management during various processes such as distribution and sales.

FIG. 1 is an enlarged perspective view showing an example of a plant holding medium 1 used in a plant cultivation method and a cultivation system according to an embodiment of the present invention, and the medium 1 is excellent in water absorption and water retention. Materials that support the seeds and roots of plants and continuously supply water (liquid fertilizer) containing fertilizer components to the seeds and roots, such as foams such as sponge made of urethane resin, rock wool, agar, gelatin and Resin fiber such as vinylon, water-absorbent resin, pulp, paper, felt and non-woven plant fiber, potting soil and cultivation soil such as Kanuma soil, hydrophilic resin, water retention material, vermiculite, peat moss, coconut husk, oasis, and crushing It is formed from materials such as stone.

As shown in FIG. 1, as the form of the medium 1, in addition to a rectangular parallelepiped including a cube, a cylinder or a sphere is preferable, and a shape for holding seeds, for example, a dent or a cut on the top surface is formed. Is preferable. Further, the medium 1 employs a means for increasing the density of the medium 1 itself in order to harden the peripheral portion so that the medium 1 does not deform or is hardly deformed even when gripped for transplant handling between bottles described later. ing. As such a medium 1, for example, a resin medium provided with fine air bubbles and having a reduced density of surrounding holes (fine air bubbles) can be applied.

FIG. 2 is an enlarged perspective view showing another example of the plant holding medium 1 used in the plant cultivation method and cultivation system according to the embodiment of the present invention, and the medium 1 is made of the same material as described above. The periphery of the formed medium 1 is covered with a film, and only the periphery thereof is hardened. Water is absorbed from the lower hole and the grown roots extend downward, and the illumination light easily enters from the upper hole. The structure is such that the grown buds come out upward. The portion 2 (hereinafter referred to as a cup portion) covered with the film and hardened has a strength that does not collapse or deform even when gripped during transplantation handling. Further, the film forming the cup portion 2 may be any of resin, plant fiber containing paper, and thin metal, and the shape may be a film-like, a net-like, or a film with holes.

This ID is used to collect various data of individual plants grown and cultivated in each medium 1. For example, it is used for individual recognition when measuring the growth of a cultivated individual (plant) at predetermined intervals in each process such as seedling raising and cultivation after sowing. The ID given to the cup portion 2 can be effectively used for goods management at the time of distribution and sale of cultivated plants. The ID to be given may be a bar code, a QR code (registered trademark), a number string, or the like that can be recognized by an individual by visual inspection or image processing.

Next, a plant cultivation method and a cultivation system using the medium 1 as described above will be described.
FIG. 3 is divided into each step of sowing / greening, raising seedlings (growing), transplanting, and planting. In the sowing / greening step, as shown in FIG. 3 (A), one pot (cultivation pallet) 3 is 16 Plants 4 are sown and greened in each medium 1 while retaining the individual media 1. Nine pots 3 holding 16 media 1 are spread adjacent to each other. As a result, 144 mediums 1 are cultivated in a state of being juxtaposed at predetermined intervals in the horizontal two-dimensional direction. The medium 1 is held in a bottle (not shown), and the whole bottle is held in the pot 3.

Next, the dimensions, specifically, the height (height) and width of three or more plants 4 in one pot 3 are measured at intervals of at least 7 days or less (after a predetermined number of cultivation days). For such measurement, various dimensional measuring means such as a camera, a 3D camera, a scale such as a ruler, and a sensor are used.

Based on the measurement results of the above dimensions (height and width), the amount of growth after a certain number of days has passed from the time of measuring the dimensions is predicted, and the adjacent interval of the medium 1 is adjusted according to the predicted amount of growth. Specifically, as shown in FIG. 3B, four media 1 in one pot 3 so that the intervals between adjacent plants 4 and 4 are suitable for raising seedlings (growing). Is transplanted and retained to grow the plant 4 in each medium 1. Also in this growing step, 9 pots 3 holding 4 media 1 are spread adjacent to each other. As a result, 36 media 1 and plants 4 are cultivated in a state of being juxtaposed at predetermined intervals in the horizontal two-dimensional direction.

Subsequently, the dimensions of three or more plants 4, specifically, the height (height) and width are measured by the above-mentioned dimension measuring means at intervals of at least 7 days or less. Then, based on the measurement result and the predicted growth amount thereafter, as shown in (C) of FIG. 3, each interval between the adjacent plants 4 and 4 becomes an interval suitable for raising seedlings (growing). One medium 1 is transplanted to one pot 3 and held to grow and cultivate the plant 4 of each medium 1. Also in this growing / cultivating step, nine pots 3 holding one medium 1 are spread adjacent to each other. As a result, nine media 1 and plants 4 are cultivated in a state of being juxtaposed at predetermined intervals in the horizontal two-dimensional direction.

Further, the dimensions of three or more plants 4, specifically, the height (height) and the width are measured by the above-mentioned dimension measuring means at intervals of at least 7 days or less. Then, based on the measurement result, as shown in FIG. 3D, one medium 1 is used so that the intervals between the adjacent plants 4 and 4 are suitable for the subsequent growth. Increase the adjacent spacing of the transplanted pots 3.

In the above embodiment, in each step of sowing / greening, raising seedlings (growing), transplanting, and planting, the height and width of the plant 4 are measured at predetermined intervals, and based on the measurement results, the adjacent plants 4, Although the adjustment of the interval in the horizontal two-dimensional direction between the four plants has been described, it is preferable to adjust the interval in the vertical direction of the vertically adjacent plants based on the measurement result.

Specifically, as shown in FIG. 4, the dimensions, specifically the height and width of the plant 4 are measured every time a predetermined number of cultivation days elapse (interval), and the upper and lower sides are measured according to the measurement results. By changing the horizontal parallel number of pots 3 to each cultivation stage of the cultivation shelf in which a plurality of cultivation stages (pot holders) are formed with different adjacent intervals, the media 1 and plants adjacent to each other are changed. Adjust the vertical interval of 4. In this case, a lighting device 5 for irradiating the cultivation light toward each plant 4 is installed on the ceiling of each cultivation stage, but the number of the lighting devices 5 installed varies depending on the cultivation stage. In particular, when the growth of the plant 4 progresses and the horizontal adjacent interval of the pot 3 becomes larger than the width of the pot 3, the number of the lighting devices 5 installed in the lower cultivation stage is reduced, so that the number of installations is increased. It is preferable to place a pot 3 for holding the plant 4 in the sowing / greening step in the cultivation stage where the light may be weak, that is, in the stage of decreasing. Further, it is preferable to install a lighting device 5 that irradiates bright and strong light in the cultivation stage that is strong and requires a lot of light.

As described above, in the present invention, the dimensions, specifically the height and width of the plant 4 are measured every time a predetermined number of cultivation days elapse (interval), and the plant or the plant is held according to the measurement result. By adjusting the adjacent spacing in the horizontal direction and / or the vertical direction of the medium 1, the leaves of the adjacent plants 4 and 4 overlap each other while ensuring high volume efficiency adapted to the growth degree of the plant 4. It is possible to prevent the parts from becoming shadows and the leaves from rubbing against each other and being damaged, and it is also possible to improve the illumination efficiency by irradiating each plant 4 with light. As a result, it is possible to always obtain optimum and high-quality cultivation conditions according to the degree of plant growth.

Here, the derivation of the predicted growth amount in this example can be considered as follows.
(1) For example, under the cultivation conditions for production, the height and width of a plurality of (preferably 3 or more) cultivated individuals are measured at intervals of at least 7 days or less, and the number of cultivation days and the average size (height and width, respectively) are measured. A growth prediction line showing the relationship of (average value) is obtained in advance. An example of the growth prediction line is shown in FIG. In addition, the weight of a plurality of cultivated individuals can be added to the measurement item, and in that case, as shown in FIG. 5, a growth prediction line showing the relationship between the number of cultivation days and the average weight may be added. Further, instead of the growth prediction line, a table (growth prediction table) showing the correspondence between the number of cultivation days and the average size and the average weight may be obtained as shown in Table 1 below.

(2) At the time of actual production, the measurement result of the dimensions of the plant 4 is applied to the above growth prediction line or the growth prediction table, and the amount of growth for a certain number of days to be installed at the next place is predicted and is the same as the predicted dimensions. Alternatively, the plant 4 is moved together with the medium to a place where there is a pitch of height and width, which is more desirable than that. Explaining with a specific example, it is assumed that the measurement result of the height is 106 mm. After that, according to the growth prediction line shown in FIG. 5, it is predicted that the height after 3 days will be 129 mm. In this case, if the shelves are installed on the same height step for 3 days, it is preferable to set the step at a position 137 mm lower than the upper step, for example, with a margin of 1 day. If the width measurement result is 145 mm, the width after 3 days is expected to be 172 mm. In this case, if the plants are to be installed in the same place for 3 days, it is preferable to set the distance between the adjacent plants 4 and 4 to 182 mm, for example, with a margin of one day. The margin may be set to, for example, about 1 to 2 days if the number of days is set as a reference, and about 10 to 20 mm if the distance is set as a reference.
When the plants 4 are individually measured, this movement may also be performed individually, and the dimensions of a group of the plurality of plants 4 are represented by a specific one or a plurality of plants 4, and only the representative dimensions are measured. If so, a group of plants 4 including the representative may be moved.

(3) After cultivating for a certain number of days, the dimensions (height and width) of the plant 4 are measured, and the size of the measurement result is compared with the size after the predicted growth. When the proportion of plant 4 in which the measurement result exceeded the predicted growth dimension (for example, 110% of the predicted growth dimension) was large, or fell below the predicted growth dimension (for example, the measurement result exceeded the predicted growth dimension). For example, when the ratio of the plant 4 (less than 90% of the predicted growth dimension) is large, the growth prediction line obtained in (1) above is corrected and applied to the next cultivation. To correct the growth prediction line, for example, the correction coefficient calculated from the average value of the measurement results may be multiplied by the value of the plot on the growth prediction line. As a result, the modified growth prediction line shown in FIG. 6 is obtained. The above correction coefficient may be a ratio between the predicted value and the measured value of the dimension at a certain time point (for example, n days after transplantation: n is a natural number).
Moreover, if the above-mentioned correction occurs frequently, the width of the above-mentioned fixed range may be widened. Examples of the above two ratios (when the ratio is large) which serve as a reference for correcting the growth prediction line include a case of 0.1%, preferably 1% or more, and more preferably 5% or more.

The above-mentioned method for deriving the predicted growth amount is just an example, and other methods can be considered. For example, under the cultivation conditions for production, the dimensions (height and width) of a plurality of (preferably 3 or more) cultivated individuals are measured at predetermined intervals for only a few days (for example, 3 to 4 days), and the measurement results are followed. The dimensions of may be estimated (extrapolated). To explain with a specific example, a pot 3 holding a medium 1 of a certain plant 4 is placed in a predetermined place, and the height of the plant 4 is set on that day (1st day) and 3 days later (4th day), respectively. Was measured. Here, when the measurement result of the height on the first day is 60 mm and the measurement result of the height on the fourth day is 90 mm, if the height on the seventh day is estimated by the extrapolation method, an estimated result of 120 mm is obtained. .. In this case, if it is installed on the same stage of the shelf until the 7th day, a margin of 10 mm should be taken and the stage should be set at a position 130 mm lower than the upper stage.

Hereinafter, a specific example will be described. In the following, the height of the plant will be referred to as the plant height, and the width will be referred to as the plant width.
First, when frilled lettuce was actually cultivated, the relationship shown in Table 2 below was obtained with respect to the number of cultivation days, the plant height (cm), and the plant width (cm).

The relationship between the conventional cultivation system and the cultivation system according to the present invention is shown in Table 3 below. In Table 3, the integrated volume is the integrated volume occupied by one cultivated product. For example, in the conventional method step 1, the shelf pitch is 3 cm in each of the vertical and horizontal directions, and the height is 30 cm, so that the shelf occupies a volume of 270 cm ³ . Since this is continued for 14 days, it becomes 270 × 14 = 3780 cm ³ days.

In the conventional method, as shown in Table 3, the seedlings are cultivated at regular intervals (3 cm pitch) for up to about 14 days, then transplanted to a float with holes at 13 cm intervals and grown for 10 days, and then grown for 10 days. It was transplanted to a float with holes at intervals of 24 cm and cultivated by a method such as 10-day growth. However, for example, when the number of cultivation days is up to 14 days, the width of the grass is wider than the pitch, so the leaves are in a state of overlapping, shadows are formed, growth is suppressed, and the grass is too long. It was.

On the other hand, in the cultivation system to which the present invention is applied, the growth is predicted and the interval and height pitch are precisely adjusted. In the case of Table 3, the pitch is 4 cm and 14 days until the 7th day. Up to 8 cm, up to 21st, 12 cm, up to 28th, 18 cm, up to 35 days, 24 cm, and the heights are changed to 5 cm, 8 cm, 11 cm, 15 cm, and 19 cm, respectively. That is, in this cultivation system, since the leaves can be cultivated so as not to overlap, the growth property is good and the effect of preventing the growth can be expected.

Moreover, the conventional method requires an average volume of 8655 cm ³ every day for 35 days, but the present method (cultivation system of the present invention) provides a volumetric efficiency of 3593 cm ³ , which is about 2.4 times higher.

By the way, the bottle used in this example may have a function of holding the medium 1 and, in the case of hydroponics, holding liquid fertilizer. It is preferable to hold one medium 1 in one bottle from the viewpoint of individual management. However, during a period when the plant 4 is small, such as during seedling raising after sowing, the handling efficiency may be improved by holding a plurality of plants 4 in one bottle.

Also, as the plant 4 grows larger, transpiration increases and a large amount of nutrient solution (liquid fertilizer) is absorbed, so a large volume is required. Therefore, it is preferable to transfer the plant 4 to a small bottle when it is small and to a large bottle when it is large. The timing of adding the liquid fertilizer to the bottle can be when the plant 4 is transferred to the bottle, or after a predetermined period of time has elapsed since the plant 4 was transferred.

Furthermore, in order to prevent the growth of algae from being promoted, it is preferable that the bottle is made of a material that does not have translucency or has a light-shielding structure. As the material of the bottle, resin or metal is preferable, and resin is more preferable. Specific examples thereof include, but are not limited to, PP, PE, PET, acrylic, ABS, and vinyl chloride.

The size (volume) of the bottle is preferably a size that allows the cultivated plant 4 to hold the required amount of liquid. Specifically, it can be 50 cc or more, 100 cc or more, 200 cc or more, 300 cc or more, and the like. If the bottle is too large, the cultivation volume efficiency will decrease, and it is preferably 50,000 cc or less, 10,000 cc or less, 3000 cc or less, and 1000 cc or less.

The width of the bottle is preferably narrower than that of plant 4 at the time of harvest. This is because when the plant 4 is small, it is desired to keep it at a pitch as narrow as possible. Specifically, it is conceivable that the thickness is 500 mm or less, 300 mm or less, 200 mm or less, and 140 mm or less. Further, in order to retain the liquid fertilizer, it is preferably larger than a certain level, and it is considered that the size is 10 mm or more, 30 mm or more, 50 mm or more, 70 mm or more.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be variously modified and implemented without departing from the gist of the present invention. For example, the following modification examples can be given.

In the above embodiment, the ID is given to the periphery of the medium 1 or the cup portion 2, but the present invention is not limited to this, and for example, the ID may be given to a bottle, or an ID is given to a member other than these. The member may be detachably connected to the medium 1 or the like, for example.

From the viewpoint of improving volumetric efficiency, it is preferable to transfer the medium 1 twice or more, three times or more, and further four times or more. Further, if the number of relocations is too large, the handling increases and the productivity decreases. Therefore, the upper limit is 100 times, preferably 50 times or less, 30 times or less, and further 10 times or less.

If the medium 1 cannot sufficiently retain (retain water) the liquid fertilizer, the liquid fertilizer may be kept in a bottle so that the roots of the plant 4 can suck it up or use the water absorption capacity of the medium 1 to supply it to the roots. preferable.

Further, it is conceivable that the periphery of the medium 1 or the cup portion 2 is installed in an upwardly open hole provided in the bottle, but in this case, at least on the periphery of the hole for ease of insertion. A taper may be provided.
