Description

  The present invention relates to an afforestation apparatus capable of planting trees without making straw, for example, even in a desert soil lacking water retention and fertilizer retention, and an afforestation system using the same.

  The ground from which forests have been cut extensively and the ground from which gravels and sands have been abandoned have been destroyed due to the destruction of the natural ecosystem and the harmonious cycle of energy being destroyed. The soil rises drastically and the topsoil is dried by evaporation. At the same time, the surface of the ground is constantly washed away by the rain, and the water absorbed in the soil elutes and drains the nutrients in the soil. It is in an environment where the growth of trees is hindered. In this way, unsuitable areas where there is a certain amount of rainfall but the nutrients of the soil are lost due to the cutting of the forest and the growth of trees is difficult are called wilderness areas. Restoring the ecosystem is a major challenge for solving environmental problems such as carbon dioxide reduction.

  On the other hand, as a plant cultivation apparatus for cultivating various plants such as flowers, vegetables, and foliage plants in the home, a water tank for storing cultivation water, an air jetting means provided on the lower side in the water tank, and a bottom part A cultivation container which is formed in the water tank and is placed in the water tank in a state where an air layer is formed between the water surface of the cultivation water and the vegetation soil inside, and the cultivation There has been proposed a plant cultivating apparatus comprising a water absorbing body that is inserted into a water absorbing body insertion hole of a container and hangs down and is immersed in water for cultivation in the water tank (see Patent Document 1). However, in such a conventional plant cultivation device for household use, since the tap water collected below is moved upward, even in the case of afforestation in a desert area, etc. In order to be able to apply a container with a long root and a relatively vertically long one, the moisture supply structure of such a conventional apparatus cannot be used because it cannot supply the stable water to the upper side of the soil necessary for the initial growth period. I can't.

JP 2002-272275 A

  Therefore, in view of the above situation, the present invention intends to solve the problem that the rainwater can be stably supplied without any deviation including the upper side of the cultivation soil. Even if you set a large value, you can always stably supply rainwater in the optimum condition from the initial growth until the roots stretch downward, and in this desert area where soil water retention and fertilizer retention has been lost. By adding fertilizer components, etc. in rainwater, it is to provide afforestation technology that prevents soil degradation for a long time while maintaining fertilizer and water retention, and enables tree planting efficiently. .

  In order to solve the above-mentioned problems, the present invention provides an outer container partially embedded in the ground and having an upper end opening, and a medium containing nutrients necessary for tree growth, provided in the outer container through a gap. An inner container to be accommodated, and provided with an opening through which a grown tree can extend at the upper end of the inner container, the upper end of the inner container protruding above the upper end opening of the outer container, A water storage part for storing rainwater entering from the upper end opening is provided in the gap between the side walls of the container and the outer container, and the rainwater stored in the water storage part is gradually inward on the side wall facing the water storage part of the inner container. An afforestation device characterized by providing pores to be infiltrated was constructed.

  Here, it is preferable that the outer container is provided with a posture holding piece that extends outward and downward from the upper end opening edge of the outer container and is supported on the ground surface to prevent the outer container from being inclined or toppled.

  Further, there is provided an opening connected to the bottom of the outer container and capable of communicating with the inside of the inner container, and provided with a lower connecting container in which a soil containing nutrients necessary for tree growth is accommodated. Is preferred.

  In addition, it is preferable that the culture medium is accommodated while leaving the upper predetermined space in the inner container, and a separately formed germination bed is mounted in the space.

  Further, the present invention is an afforestation system using the above-mentioned afforestation device, and includes a moisture measuring sensor for measuring moisture in the soil contained in the inner container, and water or liquid fertilizer via a hose with respect to the water storage unit. A water supply device that supplies incoming water, and a control computer that receives the signal from the moisture measurement sensor and controls the water supply of the water supply device in order to maintain the moisture in the culture medium of the inner container in an optimum state. We also provide an afforestation system characterized by this.

  According to the present invention as described above, rainwater or water supplied by a pump or the like is stored in a water storage section between the outer container and the inner container, and the growth of trees supplied from the outside to the soil in the inner container is performed. It is possible to supply the necessary nutrients and oxygen that enables the propagation of useful bacteria and earthworms to prevent soil degradation in a solution in the above-mentioned rainwater, maintaining an optimal soil environment for trees In addition, afforestation is possible with the device that prevents soil degradation while ensuring water retention and fertilizer retention. Therefore, while maintaining optimal water retention and fertilization without having to cover a wide area, the soil quality of the cultivation soil is prevented from deteriorating, and it is suitable for long periods even in desert areas with extremely low rainfall. Afforestation is possible.

  In particular, it has a structure in which the outer container and the inner container have a double structure, and rainwater that accumulates in the water storage part gradually enters the inner culture medium laterally through the pores of the inner container side wall from the water storage part formed in the gap. Therefore, compared to the conventional case where the rainwater collected downward is moved upward, the rainwater can be supplied stably without any deviation, including the upper side of the cultivation soil, and the vertical dimension of the inner container is set larger. However, it is always possible to stably supply rainwater to the necessary locations in an optimum state from the initial growth until the roots stretch downward. Specifically, rainwater moves preferably using both capillary action and osmotic pressure of water through the pores of the inner container side wall. If the soil inside the inner container is in a drought state, If it permeates and is saturated, moisture does not move.

  In addition, since the outer container is provided with a posture holding piece that extends outward and downward from the edge of the upper end opening of the outer container and is supported by the ground surface to prevent the outer container from being inclined or toppled, soft ground or rainwater Therefore, it is possible to prevent the entire apparatus from moving, tilting and overturning due to wind or the like, and it becomes unnecessary to fill the soil around the tree to be planted as in the conventional method to make a fence. Also, even if there is strong running water, trees will not be washed away and the surrounding soil will not be lost.

  In addition, since the lower connection container is provided which has an opening connected to the bottom of the outer container and capable of communicating with the inside of the inner container, and in which a culture medium containing nutrients necessary for tree growth is also housed. In the case where the tree to be planted is a straight root system tree having a long root part, the growth can be assisted without imposing a burden on the root.

  In addition, while storing the cultivation soil leaving the upper predetermined space in the inner container, and mounting a separately formed germination bed in the space, seedlings that have been germinated in large quantities and efficiently in the germination bed are placed on the upper part of the inner container. It can be mounted and integrated, and root damage caused by omission of labor and replanting before planting can be prevented. In normal afforestation, it is necessary to carry out treatment called “mulching”, that is, to maintain water and prevent sunburn by placing porous ceramics called water moss or “hydroball” around the root of the tree. According to the present invention, the conventional mulching is unnecessary because the germination bed is separately germinated and integrated.

  In addition, a moisture measuring sensor for measuring moisture in the soil contained in the inner container, a water supply device for supplying water or liquid fertilized water to the water storage unit via a hose, and the moisture measuring sensor In response to the signal, in order to maintain the moisture in the soil in the inner container in an optimal state, a tree planting system comprising a control computer that controls the water supply of the water supply device was constructed. Therefore, it is possible to save the input by the human power such as, and to manage the input amount and the input time efficiently and appropriately. For example, it is easy to plant trees even in a desert area where the rainfall is zero or extremely low.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a longitudinal sectional view showing a tree planting state in which trees are grown by a tree planting apparatus 1 according to the present invention. FIGS. 1 to 4 are a first embodiment of the tree planting apparatus 1, and FIGS. FIG. 7 shows an afforestation system S using the afforestation apparatus 1. In the figure, reference numeral 1 denotes an afforestation device, 2 denotes an outer container, and 3 denotes an inner container.

  As shown in FIG. 1, the afforestation apparatus 1 of the present invention is provided with an outer container 2 having an upper end opening partially embedded in the ground, and a gap in the outer container 2, and is necessary for the growth of trees. An inner container 3 in which a soil 9 containing nutrients is accommodated. In particular, a mouth 3a is provided at the upper end of the inner container 3 through which a grown tree can extend, and the upper end of the inner container 3 is on the outer side. A water storage part W is provided in the gap between the side walls 30 and 20 of the inner container 3 and the outer container 2 to store rainwater entering from the upper end opening 2a. In addition, the side wall 30 of the inner container 3 facing the water storage part W is gradually filled with rainwater stored in the water storage part W (in this example, liquid fertilizer is formed due to the presence of the fertilizer balls 8). There are provided pores 31,.

  First, based on FIGS. 1-4, 1st Embodiment of this invention is described.

  The outer container 2 is a rectangular parallelepiped whose upper part is opened, and has an inverted trapezoid shape whose diameter increases toward the upper side, thereby efficiently capturing rainwater. However, it is of course possible to use a straight shape, or conversely, a shape with a smaller diameter toward the top. In addition to the rectangular parallelepiped, it may be a cylindrical shape similar to the inner container or other shapes. The material of the outer container 2 is preferably made of wood, paper, synthetic resin, particularly biodegradable resin, but may be made of metal or other materials.

  Around the outer container 2, there is provided a posture holding piece 21 that extends at an acute angle from the edge of the upper end opening 2 a to the outside and is supported by the ground surface to prevent the outer container 2 from being inclined or toppled. It is possible to prevent the entire apparatus from moving, tilting, or overturning due to soft ground, rainwater, wind, or the like. In the present example, four plate-like posture holding pieces 21 from four sides of the opening 2a are rotatably provided at the edge of the upper end opening 2a of the outer container 2 via hinges 23, respectively. The hinge part 23 is composed of a hinge that adjusts the dynamic friction. In this way, the posture holding piece 21 is configured to be rotatable and the angle can be adjusted. It is possible to control the posture of each posture holding piece 21 to an optimum angle according to the undulations and to ensure the stability of the trees.

  A plurality of convex portions 22,... Are formed at the tip of each posture holding piece 21 along the width direction of the posture holding piece 21, and when the outer container 2 is installed on the ground surface, the posture holding piece 21 is placed inside the ground surface. It can be easily inserted into the projector, can prevent side slip after installation, and can maintain a stable posture. In this example, a plurality of convex portions 22 having a sharp tip are continuously provided in a sawtooth shape. However, the present invention is not particularly limited to such a form, and various forms such as a comb tooth shape can be employed. The material of the posture holding piece 21 is preferably made of wood, paper, or synthetic resin (for example, biodegradable resin) as in the case of the outer container 2, but can also be made of other materials made of metal. is there. In addition, if it is the same material, it is possible to integrally mold and bend the bent part as the hinge part 23,

  The inner container 3 has a conical shape (flask shape) or a quadrangular pyramid shape, and the bottom 34 of the inner container 3 is joined and integrated with the corner of the bottom 24 of the outer container 2, whereby rainwater from the bottom 34 is formed. Intrusion is prevented. As the material, various materials such as wood, paper, and synthetic resin can be applied. However, the material is preferably made of wood, waste paper, biodegradable resin, etc., and has a light shielding property. In this example, the bottom portion 34 without the bottom plate is joined to the corner of the bottom plate constituting the bottom portion 24. However, both the bottom portions 24 and 34 may have the bottom plate and may be stacked one above the other. Moreover, both sides may be configured without a bottom plate, and both bottom plates may be shared by a single bottom member.

  A through hole 26 is provided in the bottom portion 24 to block the entry of a large amount of water from the ground under the apparatus into the cultivation soil 9 and to discharge excess moisture in the cultivation soil 9 so that the moisture in the cultivation soil can be appropriately removed. It is configured to allow control. The bottom 24 is formed with a plurality of holes and slits so that it can easily break through when the root grows while withstanding the load of the internal soil, and can extend into the lower ground or the lower connecting container 4 described later. It is composed of strong kraft paper, used as cement bags, etc. or natural plant fibers such as palm, or nets knitted with biodegradable resin threads, etc. It is preferable to set it to a size that can penetrate.

  The soil 9 accommodated in the inner container 3 is one in which the soil conditions are optimally adjusted for the trees to be planted, and the soil 9 maintains the growth of the trees for a long period of time. Pre-adjusted to the condition.

  The pores 31 of the side wall 30 can gradually infiltrate the rainwater in the reservoir W (in this example, liquid manure in which rainwater, fertilizer, and oxygen are mixed) into the inner culture soil 9 side by capillary action and water osmotic pressure. The liquid fertilizer which is made into the micropore and is hold | maintained by the water storage part W according to the dry degree of culture soil will be supplied to the culture soil 9. FIG. The number of the pores 31 is provided so as to decrease toward the lower side of the side wall 30. In this way, rainwater can be effectively supplied to the upper side where water is required in the initial stage even though the pressure becomes larger and easier to enter, and rainwater can be efficiently supplied to the entire soil by infiltrating downward from there. It should be noted that not only the number but also the size of the hole is preferably set so that the upper hole is as large as possible. Moreover, it is preferable to set the space | gap of the water storage part W between the outer side container 2 and the inner side container 3 so that it may not become too wide in order to prevent the root rot by supercharging water and the decay of the water of the stored water itself.

  The mouth 3a at the upper end of the inner container 3 is composed of a dome-shaped lid 32 having a circular opening having a slightly larger diameter than the expected trunk diameter D of the grown tree as shown in FIG. It is possible to minimize the evaporation of water that has entered the cultivating soil 9 from W, and to support the trunk of the grown tree and prevent the wind from falling over. Since the mouth portion 3a is opened at a position higher than the opening portion 2a of the outer container, rainwater in the water storage portion W does not enter directly from the mouth portion 3a.

  The lid portion 32 is composed of a member that does not transmit light, and may be composed of a member different from the main body of the inner container 3 and joined to the upper end, for example. In the case where only the lid portion 32 is configured separately, various materials such as wood, paper, and synthetic resin can be applied.

  It is preferable that fertilizer balls 8 made by solidifying fertilizer and oxygen generating material in a ball shape are accommodated in the water storage portion W, and this is optimally adjusted for trees planted by dissolving in rainwater accumulated in the water storage portion W. The fertilizer and other nutrients and oxygen are dissolved in liquid fertilizer (culture medium), and this is gradually supplied to the culture soil 9 through the pores 31. Fertilizer ball 8 is a fertilizer optimally mixed with trees to be planted with nitrogen, phosphorus, potash, and other trace elements, and an oxygen-generating material solidified in a ball shape and solidified regularly. It is preferable to put in the part W. Of course, it is also possible to store the fertilizer and the oxygen ball separately.

  Here, periodic supply of oxygen is indispensable for cultivating bacteria and earthworms, which are beneficial for preventing soil degradation. By the way, simply fertilizing the surrounding surface of trees as in the case of conventional afforestation, most of the soil is spilled with rainwater in the desert, and it does not reach the necessary roots, and a certain amount of soil is needed. Although it is difficult to retain fertilizer, it is possible to reliably and stably supply liquid fertilizer to the cultivation soil by placing the fertilizer balls 8 in the water storage portion W and making liquid fertilizer with rain water as in this example. It is.

  In this example, as shown in FIG. 3, a soil 9 having an opening 4 a that is connected to the bottom 24 of the outer container 2 and can communicate with the inside of the inner container 3, and also contains nutrients necessary for tree growth. If the tree to be planted is a tree of a straight root system with a long root, providing such a lower connection container 4 can provide a long root・ Simple root trees and tree planting are possible.

  In this example, the projections 25 for bonding are provided at the four corners of the bottom 24 of the outer container 2, and the opening 4a of the lower connection container 4 is set to have substantially the same outer dimensions as the bottom 24, and the upper four corners of the opening 4a are A concave portion 40 (joint joint) that fits into the protrusion 25 is formed, and thereby configured to be detachably joined. When the lower connecting container 4 is connected and the apparatus is expanded in this way, the bottom plate of the bottom 24 is removed or used as a waste paper or cement bag with a plurality of holes or slits that can easily break through the roots. It is preferable to use a strong craft paper or a natural plant fiber such as palm or a net knitted with a biodegradable resin thread.

  Next, a second embodiment of the present invention will be described based on FIGS.

  In this embodiment, as shown in FIGS. 5 and 6, the shape of the inner container 3 is a cylinder or a straight cylindrical body of a square tube, and the culture soil is compared with a conical shape or a quadrangular pyramid as in the first embodiment. The container is structured so that it can be easily packed, and the culture medium 9 is accommodated while leaving the upper predetermined space 35 in the inner container 3, and the germination bed 10 separately formed in the space 35 can be mounted. In the first embodiment, seeds are directly embedded in the inner container 3, but an operation of taking out seeds from the container that did not germinate and embedding new seeds is performed. In this embodiment, a large number of dedicated germination beds 10 are arranged in another place, and only the germination bodies are set in the afforestation device. It will be sufficient to become seedlings and then embed them on the ground one after another. Of course, an inverted trapezoidal inverted cone or inverted quadrangular pyramid shape having a larger diameter toward the upper side or other shapes can be used.

  The germination bed 10 (nursery bed) may be, for example, a general oil-based sponge for ikebana called “Oasis”, but it absorbs water using natural materials that are treated as waste, as it is reduced to the soil. The germination bed which ensured air permeability and heat retention was constructed. That is, as shown in FIGS. 7A to 7B, the germination bed 10 is made of a fine powder of peat moss 90 dried from natural moss and finely pulverized, and fibers (cellulose) of coconut shells. Mix a powder 91 similar to wood chips, called coco patet (registered trademark), and add a little natural paste (starch paste such as corn starch, a thickener made from corn starch). It is molded into a predetermined shape and molded into a hemisphere (dome shape) having a circular bottom surface having the same diameter as the inner diameter of the inner container 3 so as to fit into the upper space 35 of the inner container 3. As a result of the experiment, the germination rate was much higher than that of the petroleum sponge. The bottom surface can be formed into a square, polygon, or other shape according to the cross-sectional shape of the inner container 3.

  The upper part of the germination bed 10 is formed with a concave hole 11 for containing the seed 12, so to speak, has a shape like “Mt. Fuji”, and the seed 12 is poured into the top caldera portion (concave hole 11) and watered. For example, moisture spreads throughout and the temperature and breathability are optimized to germinate in a very short time. The germination bed 10 does not require fertilizer or water, and the three elements of water, oxygen (air), and temperature may be adjusted appropriately. This germination bed 10 is porous because it is formed from natural plant cellulose in a pilled state, and has air permeability, water retention and heat retention essential for germination and rooting of seeds, and has the same effect as mulching. There is also.

  As shown in FIG. 7 (c), the seeds root in this “Mt. Fuji” type germination bed, roots extend, and stems emerge. The roots extend downward, the stems extend upward, and when the roots reach a certain length, then the stems extend upwards and cotyledons (foliage) open. At this stage, the entire germination bed is set on top of the inner container of the device. Even if there is no dome (lid part) as in the first embodiment, the germination bed 10 functions to block light and water. Moreover, since the seedlings are not replanted, the planting work can be performed efficiently without damaging the plants.

  After germination and rooting, the roots extend below the bed, and then the stems grow and the cotyledons (foliage) open. As the root grows, water and nutrients are obtained from the germination bed 10 into the optimized soil 9 inside the inner container 3 as shown in FIG. 7 (d). After some time after germination, it is set in a device and if the tree height reaches, for example, about 30 cm, it is buried in the ground of a desert area as it is. In general, direct seeding has a low germination rate, but according to this example, germination can be carried out in a large amount in a germination bed, and a mulching effect that is indispensable for the growth of trees can be provided while preventing root damage of seedlings by replanting.

  In addition, the shape and structure of the outer container 2 and the inner container 3 constituting the afforestation device 1, the connection structure with the material and the outer container, and other modifications are basically the same as those of the first embodiment. The same structure is denoted by the same reference numerals, and description thereof is omitted.

  Next, the afforestation system S using the afforestation apparatus 1 of this example is demonstrated based on FIG. In addition, although this example demonstrates what manages a plurality of the tree planting apparatuses 1, of course, you may manage only one.

  As shown in FIG. 8, the afforestation system S includes a moisture measuring sensor 5 that measures moisture in the soil 9 accommodated in each inner container 3 of the installed afforestation device 1, and a water storage unit W of each afforestation device 1. Water supply device 6 for supplying water or water containing liquid fertilizer via hose 65 and a signal from water measurement sensor 5 to supply water to maintain the moisture in culture medium 9 of the inner container in an optimum state. It is provided with a control computer 7 for controlling the water supply of the device 6, thereby saving the input by manpower of the fertilizer balls 8 to each afforestation device 1 and managing the input amount and timing more strictly. it can.

  The water supply device 6 temporarily stores the water pumped up from the water reservoir 60 by the pump 63 in the water storage tank 61, and liquid fertilizer is appropriately mixed from the liquid fertilizer tank 62 into the water storage tank 61, and from the water storage tank 61 through the hose 65. It consists of a facility in which liquid fertilized water is supplied to the water storage section W of each tree planting apparatus 1. In this example, a switch of the pump 64 for discharging from the water storage tank 61 to the hose 65, or an electromagnetic flow valve provided in the middle of the hose (Electromagnetic valve) is connected to the control computer 7 to control water supply. In desert areas where there is no or extremely little rainfall, afforestation is possible if water pumped up from the reservoir 60 is supplied to the water storage tank 61 using this system instead of rain as in this system. As the moisture measuring sensor 5, a known sensor such as a dielectric constant moisture measuring sensor for measuring soil moisture from the dielectric constant can be used. When the water supply is controlled, the moisture in the cultivating soil 9 is transferred to the control computer 7. Optimum control is performed by feedback.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention.
