Description

[Technical Field]

[0001] The present invention relates to a soil cultivation container in which soil is stored in each of the soil cultivation containers arranged in series to form soil cultivation ridges, and the top surface of the soil is covered with a soil covering sheet for weed prevention or moisture retention, as well as to a soil cultivation ridge constructed using the soil cultivation containers, and a method of cultivating agricultural crops using the same. [Background technology]

[0002] For example, when cultivating tomatoes, the planting position in the ridge mulch (a soil covering sheet for weed control, moisture retention, or heat retention) that covers the ridges is cut open, planting holes for the seedlings are dug, the seedlings are planted or the seeds are sown, and then the tomatoes (crops) that have taken root or sprouted and taken root and grown are harvested when they have grown large.However, until now, there has been no crop cultivation method that allows seedlings to be planted or seeds to be sown without having to cut open the ridge mulch and dig planting holes until harvest.

[0003] In other words, not only is the work of cutting open the ridge mulch troublesome, but the even more troublesome work of replacing the ridge mulch with new ridge mulch when the next seedlings grow from the cut and the next harvest is ready to be planted is required, and there has been no method of growing crops that does not require such troublesome work. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the current situation, the present invention aims to provide a soil cultivation container that allows seedlings to be planted and harvested without having to cut open the soil covering sheet 1 (ridge mulch) and dig planting holes until harvest, and that makes it extremely easy to replace the ridge mulch, as well as soil cultivation ridges using this soil cultivation container and a method for cultivating agricultural crops using the same. [Means for solving the problem]

[0005] The gist of the present invention will be explained with reference to the accompanying drawings.

[0006] The present invention relates to a soil cultivation container characterized in that a seedling storage section 4 is provided on the side of a soil cultivation container 2 that stores soil for soil cultivation and has a soil covering sheet 1 on top of the soil for weed prevention or moisture retention, and that stores seedlings 3 for cultivation along with a small amount of soil for soil cultivation, or soil in which seeds will be sown and the seedlings 3 will grow, and that a root passage hole 6 is provided on the side of the soil cultivation container 2 inside this seedling storage section 4, through which roots 5 growing from the seedlings 3 grow and penetrate into the soil in the cultivation container 2.

[0007] The seedling storage section 4 is also shaped and sized to allow the seedlings 3 grown in the seedling pots to be removed from the seedling pots and placed in storage together with a small amount of soil, and the bottom protruding from the side of the cultivation container 2 is designed to have a bottomed, holeless shape so that the roots 5 of the seedlings 3 that grow and reach the cultivation container 2 can grow and penetrate into the cultivation container 2 through the root passage holes 6 on the side of the cultivation container 2.

[0008] The present invention also relates to a soil cultivation ridge using a soil cultivation container, characterized in that the soil is stored in the soil cultivation container 2 of the soil cultivation container described in claim 1 or claim 2, or in that multiple soil cultivation containers described in claim 1 or claim 2 are arranged in series and the soil is stored in the soil cultivation container 2 of these multiple soil cultivation containers, and the soil covering sheet 1 is covering the upper surface of the soil in the soil cultivation container 2.

[0009] The present invention also relates to a soil cultivation ridge using a soil cultivation container as described in claim 3, characterized in that the soil cultivation containers as described in claim 1 or claim 2 are stacked one on top of the other, and the soil and fertilizer are stored in the soil cultivation containers 2 of the upper and lower soil cultivation containers, respectively.

[0010] The present invention also relates to a soil cultivation ridge using a soil cultivation container as set forth in claim 3, in which a hydroponic cultivation container for hydroponic cultivation is provided below the soil cultivation container as set forth in claim 1 or claim 2, and a hydroponic cultivation section consisting of the water tank section 7 of the hydroponic cultivation container is provided below the soil cultivation section consisting of the soil cultivation container 2 of the soil cultivation container, and a root passage bottom is provided at the bottom of the soil cultivation container 2 so that the soil does not fall through but the growing roots 5 can pass through, so that even though the cultivation is in soil, the roots 5 growing downward in the soil reach the water in the water tank section 7 of the hydroponic cultivation container below, making it possible to carry out hydroponic cultivation while also carrying out soil cultivation.

[0011] This is a method of cultivating crops using a soil cultivation ridge using the soil cultivation container described in claim 3, which is a soil cultivation ridge using the soil cultivation container described in claim 4 or claim 5, and which involves cultivating seedlings 3 in soil and harvesting crops.The seedlings 3 are cultivated in the seedling storage section 4, and the soil covering sheet 1 is cut to plant the seedlings 3, but the seedlings do not grow from the cut end, making it a cultivation method in which the soil covering sheet 1 can be easily replaced or inverted to cover the seedlings. [Effects of the Invention]

[0012] Since the present invention is configured as described above, seedlings can be planted and harvested without having to cut open the ridge mulch and dig planting holes until harvest, and the ridge mulch can be replaced very easily, resulting in a soil cultivation container, a soil cultivation ridge using this soil cultivation container, and a crop cultivation method using the same.

[0014] The best mode for carrying out the present invention will now be briefly described with reference to the accompanying drawings, illustrating the operation of the present invention.

[0015] Soil for soil cultivation is stored, and the top surface of the soil is covered with a soil covering sheet 1 (ridge mulch) for weed prevention or moisture retention, and seedlings 3 for cultivation are stored in a seedling storage part 4 provided in a protruding state on the side of the soil cultivation container 2 together with a small amount of soil for soil cultivation, or seeds are sown in the stored soil to grow the seedlings 3.

[0016] Roots 5 growing from the seedlings 3 in the seedling storage section 4 pass through root passage holes 6 provided on the side of the soil cultivation container 2 inside the seedling storage section 4, and grow into the soil inside the cultivation container 2. The seedlings 3 grow, produce fruit on their stems and branches, and are harvested as agricultural crops.

[0017] Therefore, in the present invention, rather than cutting the soil covering sheet 1 and planting the seedlings 3 from the cut end, it is sufficient to simply place the seedlings 3 with soil removed from, for example, a seedling pot into the seedling storage section 4 protruding from the side of the soil cultivation container 2, which not only makes planting the seedlings 3 easier, but also makes it extremely easy to replace or invert the soil covering sheet 1, since the seedlings 3 do not grow from the cut end of the soil covering sheet 1. Furthermore, the roots 5 of the seedlings 3 penetrate and grow into the soil of the soil cultivation container 2, and the seedlings 3 grow and become large within the seedling storage section 4 on the side of the soil cultivation container 2, and therefore do not grow at the planting position of the soil covering sheet 1, which makes it even easier to replace or invert the soil covering sheet 1.

[0018] That is, for example, when cultivation and harvesting are completed in early spring and a second crop is to be grown, the black soil covering sheet 1 is replaced with a white soil covering sheet 1, or if the soil covering sheet 1 is black on one side and white on the other, it is inverted to prevent high temperatures due to drought in summer. In this case, the stems of the seedlings 3 that have been harvested are located on the side of the soil cultivation container 2 that contains soil and is covered with the soil covering sheet 1, and these stems can be cut or pulled out simply by cutting or pulling them out. Since the seedlings 3 do not grow from the cuts at the planting position in the soil covering sheet 1 as in the past, the soil covering sheet 1 can be replaced easily and quickly. Furthermore, because the sheet 1 is not constantly cut or torn by pulling out the stems, the soil covering sheet 1 is always clean, and replacement and inversion are extremely easy. [Example]

[0019] Specific embodiments of the present invention will be described with reference to the drawings.

[0020] In this embodiment, a seedling storage section 4 is attached to the side of a soil cultivation container 2 (a synthetic resin container for storing soil, fertilizer, rock wool, etc.) that is square in plan view and is arranged in a series (vertical row along the length of the container) to form ridges, and is used to store seedlings 3 for cultivation along with a small amount of soil for soil cultivation, or to sow seeds and grow the seedlings 3.

[0021] Specifically, soil cultivation containers 2 containing soil (cultivation soil) for soil cultivation are lined up in a vertical row (and if there is space, multiple rows can be lined up) to form long ridges in the vertical direction, and a commercially available soil covering sheet 1 (ridge mulch) for weed prevention or moisture retention, which is long in the vertical direction, is covered (stretched) on top of the soil in the soil cultivation containers 2 lined up in a vertical row.

[0022] As mentioned above, the upper side of this soil cultivation container 2 is provided with a seedling storage section 4 that protrudes to the side and is of a size (shape) that allows for the direct placement and storage of seedlings 3 with a small amount of soil attached, for example, after they have been taken out of a seedling pot, which is convenient for cultivating and transporting seedlings.

[0023] In this embodiment, a root passage hole 6 is provided on the side of the soil cultivation container 2 inside the seedling storage section 4, through which roots 5 growing from the seedlings 3 grow and penetrate into the soil in the cultivation container 2 through an opening on the inside side of the seedling storage section 4. This root passage hole 6 may be configured as some of the many scattered holes provided on the side of the cultivation container 2, or may be configured as a large hole formed on the side of the seedling storage section 4 that communicates with the opening on the inside side.

[0024] To explain further, the seedling storage section 4 of this embodiment is shaped and sized so that seedlings 3 grown in seedling pots, which are convenient for cultivating and transporting seedlings, can be removed from the seedling pots along with a small amount of soil attached to their roots 5 and then placed in and stored as is.The roots 5 penetrate and grow within the soil cultivation container 2, but the seedlings 3 are set to a size sufficient to grow within them (slightly larger than the seedling pot), and are configured to protrude from the upper side of the cultivation container 2.

[0025] The seedling storage section 4 may be attached to the soil cultivation container 2 after the fact, or may be integrally molded. In this embodiment, the seedling storage section 4 has no hole in the bottom, and the roots 5 of the growing seedlings 3 will grow inward even if they reach the bottom, and will grow into the soil cultivation container 2 from the opening on the inside side of the seedling storage section 4 through the root passage hole 6 on the side of the cultivation container 2.

[0026] In this embodiment, soil (cultivation soil), fertilizer, rock wool sheets, etc. are stored in the soil cultivation container 2 of the soil cultivation container configured in this manner, and these are arranged in a vertical row.The long soil covering sheet 1 is then covered on top of the soil to form soil cultivation ridges.

[0027] In this embodiment (Example 1), the soil cultivation containers are arranged in a vertical row to form soil cultivation ridges, and the soil cultivation containers are stacked vertically to form the soil cultivation ridges. Specifically, each of the soil cultivation containers 2 of the upper and lower soil cultivation containers contains a rock wool plate that allows water and roots to pass through, and the culture soil is stored on top of this, and fertilizer is also stored so that the layers are positioned at a predetermined height. These are stacked in three layers, one above the other, to form a soil cultivation section (soil cultivation ridge) made of the soil cultivation containers 2, and the top soil is covered with the long soil covering sheet 1 (ridge mulch).

[0028] On the other hand, in Example 2, a long hydroponic container for hydroponic cultivation is provided below this soil cultivation container, and a hydroponic cultivation section by the water tank section 7 of the hydroponic cultivation container is provided below the soil cultivation section by the soil cultivation container 2 of the soil cultivation container. Specifically, in Example 2, a root passage bottom (rock wool plate or net, etc.) is provided at the bottom of the soil cultivation container 2 so that the soil does not fall but the growing roots pass through. Although it is soil cultivation, the roots 5 growing downward in the soil reach the water in the water tank section 7 of the hydroponic cultivation container below, and by adding liquid fertilizer as appropriate, it is possible to realize the applicant's new hybrid farming method that can perform both soil cultivation and hydroponic cultivation (implementing the invention of the applicant's Patent Application No. 2023-049116).

[0029] First, Example 1 will be described. In Example 1, as described above, the containers 2 for soil cultivation, each containing culture soil, fertilizer, and rock wool plates, are stacked in three layers, one above the other, and arranged vertically to form a soil ridge, and a long soil covering sheet 1 (ridge mulch) is placed over the top surface of the soil in the containers 2 for soil cultivation in the top layer.

[0030] Traditionally, for crops such as tomatoes, the soil in the field is plowed, and ridges are made on the bottom of the field with culture medium (plowed potting soil mixed with base fertilizer). These ridges are then covered with ridge mulch (a soil covering sheet1 for weed control, moisture retention, or heat retention). After this, the ridge mulch is cut open at the position where the seedlings will be planted, and planting holes are dug. Careful not to let the holes collapse, the seedling pots are tilted at about 45 degrees, and the seedlings are removed from the pots while being careful not to let the soil from the pots fall onto the mulch. After placing the seedlings in the planting holes, they are gently pressed down with both hands.

[0031] Furthermore, with vine vegetables such as tomatoes, the higher the tier (from the third tier onwards), the slower they bear fruit, the less sweet they become, and the poorer the fruit becomes, resulting in smaller fruits. Therefore, when the plants begin to bear fruit in the first, second and third tiers, the mulch on the ridges is removed and a top dressing of organic granular fertiliser is applied to the top of the ridges and watered. However, although some of the granular fertiliser on the ridges dissolves in the water for this watering and reaches the roots, it is not enough to provide the amount of fertiliser needed to ensure that fruits on the fourth tier and above bear the same amount of fruit as those on the first, second and third tiers.

[0032] Therefore, liquid fertilizer, which easily reaches deep into the soil, is applied to the top of the ridges in the amount required to produce the calculated amount of fruit in the upper tiers. However, even so, from the fourth tier onwards, the sweetness fades, the body becomes shallow, and the fruit becomes smaller. However, planting in ridges with a large amount of granular fertilizer applied all at once will result in "tree decay," damaging the entire plant, even from the seedling stage. Maintaining fruit size without losing sweetness can also be achieved by applying organic granular fertilizer as a waiting fertilizer (as a top dressing in the soil) to the root expansion zone of each tier. However, for example, in a six-tier tomato plant, applying the amount of fertilizer needed to produce large, sweet fruit all the way to the sixth tier in one go without causing "tree decay" would require creating six ridges and applying granular fertilizer at the boundary between the layers. However, creating such ridges is extremely cumbersome and impossible.

[0033] Instead, smart agriculture (plant factories) using ICT and rock wool as a cultivation medium has become popular, but smart agriculture using rock wool as a cultivation medium necessitates the disposal of large amounts of rock wool, which is extremely harmful to the environment and places an immeasurable burden on the environment.If smart agriculture using rock wool as a cultivation medium, which necessitates the disposal of large amounts of rock wool, becomes popular, it will pose major environmental problems and will be a farming method that goes against the SDGs.

[0034] Rock wool (artificial mineral fiber) is made by melting rocks at high temperatures in the same way as cotton candy is made, but the fossil fuels and exhaust gases used in the process, as well as the energy and exhaust gases needed to incinerate it after use, are a constant problem. On farms that cannot cover the costs of incineration, the waste is left out in the open after illegal dumping, which causes air pollution due to weathering and deterioration.

[0035] Furthermore, smart agriculture using rockwool, which is unavoidably disposed of in large quantities, has been developed to eliminate or overcome the disadvantages of conventional soil-based cultivation, but by making some ingenuity in the positioning of the culture soil and the fertilizer in the culture soil, as in Example 1, Example 1 and others can have effects that go beyond smart agriculture.

[0036] In addition to the points mentioned above, this embodiment is environmentally friendly in various respects compared to smart agriculture using ICT with rock wool medium, and does not require any initial equipment costs.

[0037] This embodiment (Example 1) solves these problems and is configured to easily apply layered fertilizer application to the ridges (fertilizer application in the culture medium). This makes it possible, for example, to grow tomatoes up to the sixth tier to be the same size and sweetness as the first tier. Seedlings (root balls removed from seedling pots) can be planted without cutting the mulch at the seedling planting position and digging planting holes. It is also possible to switch the front and back (white and black) of the mulch on the ridges and reuse the mulch. Furthermore, if a string attachment section 8 is provided on the container, the crops can be easily supported with the string, eliminating the need to tie strings to the root stems of the crops (tomatoes, melons, etc.). Furthermore, this realizes an unprecedented, revolutionary crop cultivation method that can solve or reduce the above-mentioned disadvantages of smart agriculture that uses rock wool culture media.

[0038] On the other hand, in Example 2, as mentioned above, the invention of Patent Application No. 2023-49116, which is the applicant's groundbreaking new hybrid farming method, is used. A soil cultivation container containing the culture soil, fertilizer, and rock wool board of Example 1, which is configured to allow roots to pass through but not drop the culture soil, is used, and a long hydroponic cultivation container, for example, is constructed below it. In other words, the soil cultivation containers 2 of multiple soil cultivation containers are arranged vertically on top of the long water tank section 7 of this hydroponic cultivation container, and the roots 5 grown in this soil cultivation container 2 reach the water stored in the water tank section 7 below and to which liquid fertilizer is added, thereby realizing a new hybrid farming method that is both soil cultivation and hydroponic cultivation.

[0039] To explain further, in all embodiments, the seedling storage section 4 on the side of the soil cultivation container 2 is filled with a small amount of soil from the upper edge, leaving a depth (thickness) equivalent to the seedling's root ball. After the seedling 3 with soil (root ball) removed from the seedling raising pot is placed in this seedling storage section 4, more soil is poured into the seedling storage section 4 to bury the root ball. By pouring plenty of water on top of this soil, the soil surrounding the seedling 3 and burying the root ball is compacted, completing the planting process. The roots 5 of the seedling 3 then grow from the seedling storage section 4 toward the soil in the soil inside the soil cultivation container 2.

[0040] Also, for example, by providing a hook- or wedge-shaped notch on the upper edge of the soil cultivation container 2 or the seedling storage section 4 provided therein to provide a string hanging section 8, the string for supporting crops such as tomatoes, melons, etc. can be hung around this string hanging section 8 or inserted into the notch and wrapped around once, eliminating the need to tie the string to the base stem.

[0041] Furthermore, by providing the seedling storage sections 4 on the left and right sides, the rows can be used consecutively without having to "empty" the rows between the first and second crops, as was previously required for clearing the rows between the first crop and preparing to plant the second crop. Specifically, if the lower branches and leaves of the first crop are removed, the seedlings 3 for the second crop can be planted in the seedling storage section 4 on the other side at the end of the first crop, when the first crop's fifth and sixth rows have ripened.

[0042] In ridge cultivation using this type of soil, black ridge mulch (soil covering sheet 1) is used in early spring to ensure the soil temperature rises due to sunlight and to block light to prevent weeds on the ridge surface. Ideally, as the summer approaches and the sun gets stronger, this black mulch should be replaced with white ridge mulch (soil covering sheet 1) to prevent the soil temperature from rising too much. However, in early spring, the black mulch could not be removed because the seedlings 3 had already been cut through and planted and their stems had already grown. However, in this embodiment, the seedlings 3 grow from the seedling storage section 4 of the soil cultivation container 2, and the mulch is not cut through and penetrated as in the conventional example. Therefore, by using a mulch of approximately the same width as the soil cultivation container 2, replacement is easy. Furthermore, if a commercially available ridge mulch with two sides (black and white) is used, it can be easily turned over, making replacement easier.

[0043] Specifically, for example, by removing the mulch holding rod 9 that holds down the ridge mulch on the soil cultivation container 2 from the groove 10 on the upper edge of the container 2 and turning the ridge mulch over, it is possible to prevent the ridge soil from overheating. Also, this ridge mulch, which was previously disposable after each crop, can now be reused multiple times.

[0044] Therefore, in this example (Examples 1 and 2), the cutting of mulch and digging of planting holes required for conventional planting work are no longer necessary, the mulch can be switched between the white and black sides, mulch (nylon) can be reused, and the most time-consuming task of tying strings to the base of the plant is no longer necessary. Furthermore, in Example 1, by making some ingenuity in the relationship between the position of the vegetable roots moving through the soil and the position of the fertilizer placed in the soil, the inconvenience of the soil on the vegetable roots can be reduced. This will encourage a reconsideration in the greenhouse horticulture industry, which has been overwhelmed by rock wool substrates, ICT, computer-controlled drip feed, and drip irrigation, and will realize an unprecedented, groundbreaking crop cultivation method that will put an end to smart agriculture using rock wool substrates, which places an immeasurable burden on the environment for the sake of simple tomatoes and melons.

[0045] For example, the soil cultivation container 2 in Example 1 uses a rectangular resin soil storage case with a thickness (height) of 10 cm, width of 30 cm, and length of 40 cm for tomatoes, and these soil cultivation containers 2 (soil storage cases) are stacked in three tiers with potting soil filled and organic granular fertilizer spread evenly on top of them.These three tiers are lined up lengthwise to form ridges with a height of 30 cm, width of 30 cm, and length of 4 m (for example, in the case of 10 cases).One container of potting soil and fertilizer in this soil storage case can support the fruit of two tiers of tomatoes, making it possible to grow tomatoes of approximately the same size and sweetness from the first to sixth tiers in a six-tier cultivation system.

[0046] That is, in Example 1, when the soil storage cases (containers for soil cultivation 2) are stacked in three tiers and these three tiers are lined up lengthwise to form ridges, when seedlings 3 (root balls) are planted in the seedling storage section 4 located in the center of the upper side of the upper soil storage case, the roots 5 proceed through the root passage holes 6 into the soil in the soil storage case, and then through the rock wool board about 3 cm thick at the bottom of the upper soil storage case, which does not allow fine soil to pass through but does allow water and roots to pass through, and the mesh section pressed underneath that does not allow anything other than fine soil to pass through, and then through the root passage bottom of the bottom board, which has many openings that allow both water and roots to pass through, and proceed to the soil storage case in the middle tier, and then follow the same process to reach the soil storage case in the lower tier, resulting in good fruit.

[0047] The top surface of the soil in the top soil storage case (container for soil cultivation 2) is covered with ridge mulch (soil covering sheet 1), which is held down by a mulch holding rod 9.

[0048] Furthermore, as mentioned above, the benefits of providing multiple seedling storage sections 4 in a soil storage case are immeasurable. In this embodiment, (1) there is no need to prepare seedlings for each planting, (2) tying the string to the base of the plant can be completed in just 5 seconds using a wedge-shaped notch, and (3) soil cultivation using a culture medium produces fruit of much higher quality than that produced by semi-hydroponic smart agriculture, which uses porous materials such as sponges or rock wool as a culture medium and nutrient solution (liquid fertilizer), i.e., chemical fertilizer. Furthermore, good materials have been developed in recent years, such as culture medium specifically for nutrient solution soil cultivation. This culture medium can be stored in a soil storage case and used for continuous planting for 10 years without tilling, as has been proven. This soil is placed in the seedling storage sections 4 on the left and right and in the soil storage case, and the "masari" (the stem that sprouts from the base of the branches and leaves growing from the stem) of a tomato seedling planted in the first seedling storage section 4 on the first level (on one side) is used to graft a cutting of this masari into the second seedling storage section 4 on the opposite side to create a masari seedling, which is then grown in the third seedling storage section 4 on the second level (on one side). The "masari" from this third tomato is taken and grafted into the fourth seedling storage section 4 on the second level (on the opposite side) to create a masari seedling, and by continuing to send the cuttings up to the sixth seedling on the third level, a low-level, densely planted, multi-rotation continuous cultivation method for tomatoes using masari seedlings can be carried out, allowing for six consecutive plantings per year from the first seedling.

[0049] In addition, in Example 2, three seedling storage sections 4 are provided on each side of the soil storage case (container for soil cultivation 2), making it possible to realize a low-tier, densely planted, multi-rotation continuous cultivation method for tomatoes using Masari seedlings, which allows six consecutive plantings per year from one seedling, even though it is a single tier.

[0050] In any of the embodiments, a configuration may be adopted in which water is automatically sprinkled from above at a fixed time, and in the second embodiment, a configuration may be adopted in which liquid fertilizer is added to the water for hydroponic cultivation in the water tank section 7 below, and this water is automatically pumped up and sprinkled from above using a sprinkler pipe. However, in this embodiment, a configuration is adopted in which a water channel 14 is formed below, and a water supply storage tank section 11 is provided on the side of each row in communication with this channel, and a water supply and drainage pipe 12 is provided in this water supply storage tank section 11 to supply and drain water via a pump, and a pump control section is provided to control the pump capacity of the pump that supplies and drains water via this water supply and drainage pipe 12. A pump 13 is provided to periodically operate the pump and control it to a predetermined water supply and drainage capacity to supply and drain water to the water storage tank 11, thereby enabling water to be supplied from below to the soil in the soil container 2 (soil storage case) via the lower water channel 14. In other words, the supplied water is supplied from the water storage tank 11 to the underside of the soil via the water channel, and the soil automatically and slowly absorbs the water, spreading it over the entire soil surface. Furthermore, by controlling the drainage, the absorbed water is drained via the lower water channel 14, thereby serving as an alternative to sprinkling water. In addition, in Example 2, the water tank 7 of the hydroponic container serves as the lower water channel 14, i.e., performs this water channel function.

[0051] The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate. [Explanation of symbols]
