Description

  The present invention relates to a nursery floor panel that is placed on a stand and used for raising seedlings, etc., and relates to a bottom irrigation water supply panel that irrigates from the bottom of the cultivation pot and a cultivation pot for the panel. The present invention also relates to a cultivation system using the bottom irrigation water supply panel and a cultivation pot for the panel.

  Up to now, overhead irrigation, which is generally performed using a sprinkler or the like from above the plant, is most popular because it requires less initial cost in terms of equipment and is easy to construct. However, if overhead irrigation is compared to water supply to plants in nature, it seems to be encountering rain every day, and it cannot be said that it is a natural state considering that plants will be spoiled by long rain. In addition, overhead irrigation causes water supply unevenness, and in order to compensate for this, not only is it time-consuming to irrigate, but also over-irrigation tends to occur. In addition, there are many problems due to the spread of disease caused by the scattering of water droplets and the spread of disease by spreading bacterial cells and spores. In addition, when growth progresses and leaves grow, it is difficult for water to enter the pot. Also, the temperature of the seedling culture soil becomes high and root rot is likely to occur, and it is difficult to grow good seedlings. Among these problems, in order to solve the biggest problem of water supply unevenness, even if a self-propelled sprinkler is used, uniform irrigation is possible, but it requires a large initial investment and overhead. The problem with irrigation cannot be solved.

  Therefore, there is a device disclosed in the following Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-288392) as a seedling raising apparatus for drip irrigation to the root of a plant instead of overhead irrigation. As shown in FIG. 9, this seedling raising device includes a cell tray 81 in which a plurality of storage portions 82 for filling a medium 83 for planting seedlings 84 are formed, a water retention sheet 85 that covers the upper surface of the cell tray 81, and a water retention sheet And a watering device 86 for supplying water. The water retentive sheet 85 includes a drip part 87 located in the opening of each storage part 82 provided in each cell tray 81, and the drip part 87 located in the opening supplies water supplied to the water retentive sheet 85. Water is supplied by dripping into the storage part 82. The irrigation tool 86 is an irrigation hose 86A disposed on a water retention sheet, and includes a water supply port 88 opened horizontally or downward at a predetermined interval to supply water to the water retention sheet 85.

  However, since the water retaining sheet covers the medium 83 and supplies water dropwise to the medium, the water supply is not constant if the medium conditions are different. Since water supply is performed from above the culture medium, it is different from water supply in the natural state, unlike bottom surface water supply. Because the culture medium is separated from the ground and the volume of the culture medium is small, it is easily affected by the ambient temperature, and in hot summer, it becomes hot and easily causes oxygen deficiency, which tends to cause root rot. Moreover, since the irrigation hose is arrange | positioned on a water retention sheet | seat, it moves with water supply pressure, a wind, etc., and a position is not stabilized.

  On the other hand, the bottom and drip irrigation, which is a method of supplying water to the roots of plants, can be said to be a irrigation method close to the natural state. Not.

FIG. 4 is a cross-sectional view of an embodiment for explaining the structure of the cultivation pot setting portion, and FIG. 5 is a cross-sectional view of another embodiment for explaining the structure of the cultivation pot setting portion. 6 and 7 are a side view and a bottom view for explaining the structure of the cultivation pot. FIG. 8 is an explanatory view of one embodiment of the drain receiver in the cultivation system of the present invention, where FIG. 8 (a) is a front view and FIG. 8 (b) is a side view.

  This bottom irrigation cultivation system includes a plurality of cultivation pots on a bottom irrigation water supply panel (hereinafter referred to as a water supply panel) 1 formed from a panel 2 made of synthetic resin or synthetic paper having a predetermined width, length and thickness. And the water supply liquid is intermittently supplied from the water supply tube 4 to the cultivation pot via the irrigation groove 3 at a predetermined timing. This water supply panel 1 is normally used by being placed on an elevated floor base 8.

  Referring to FIG. 1, the water supply panel 1 has a longitudinal direction by a press on the surface of the panel 2 that forms a rectangular support plate body having a predetermined lateral width and length, for example, a width of 90 cm and a length of 120 cm. The formed irrigation groove 3 is provided, and the cultivation pot installation part 6 is provided at the end of the irrigation groove 3. A plurality of irrigation grooves 3 are formed substantially in parallel with the width direction of the water supply panel 1 (a total of eight, 3a, 3b, 3c... 3h), and each irrigation groove is orthogonally crossed from the irrigation groove 3a to the irrigation groove 3h. The irrigation groove 3x for communication formed so as to be formed is provided. In this way, the irrigation grooves 3a to 3h and the irrigation groove 3x form vertical and horizontal ladder-shaped irrigation channels, and the cultivation pot 7 is installed in the cultivation pot installation unit 6 provided at the end of the irrigation grooves 3a to 3h. The cultivation pot installation unit 6 is arranged so that the distance from a plurality of adjacent other cultivation pot installation units 6 is the same in order to make the seedlings as uniform as possible. The irrigation groove 3 and the cultivation pot setting unit 6 described above constitute one group, and the same group is provided in parallel on the water supply panel 1 over a plurality of length directions. In FIG. 1, four groups are provided.

  A dropper 5 is installed at a predetermined position above the irrigation groove 3x for communication. In addition, a drip receiving groove 9 is provided in a portion of the communication irrigation groove 3x where the dropper 5 is installed. A water supply tube 4 (see FIG. 3) is connected to the dropper 5. As a result, the water supply liquid is supplied from the water supply tube 4 to the dropper 5, dropped from the dropper 5 into the drip receiving groove 9, passes through the irrigation groove 3 x for communication from the drip receiving groove 9, and each of the irrigation grooves 3 a to 3 h. And water is supplied to the cultivation pot installation unit 6. If the water supply liquid is once accumulated in the drip receiving groove 9 from the dropper 5 and then allowed to flow into the irrigation groove 3, it is possible to reliably supply water without waste as compared with the case where water is directly supplied from the dropper 5 to the irrigation groove 3. Then, as shown in FIG. 4, when the water supply tube 4 and the dropper 5 are stored in the drip receiving groove 9, the water supply tube will not be violated or moved by water pressure or wind pressure applied to the water supply tube 4. If the drip receiving groove 9 is formed so that the irrigation groove 3 for communication is slightly wide at the position of the dropper 5, the water supply liquid is less likely to spill.

  Further, as shown in FIG. 4, the water supply panel 1 has a lower die cost when the irrigation groove 3 is formed flat, and the water supply panel 1 is provided with an existing cell tray or small depth tray. Can do. However, as shown in FIG. 5, when the irrigation groove 3 is inclined so as to become lower from the position where the dropper 5 is installed toward the cultivation pot installation unit 6, water and culture solution can be smoothly passed through the irrigation groove 3. It can be supplied and the backflow can be prevented.

  Next, the cultivation pot setting unit 6 will be described in detail mainly with reference to FIGS. 4 and 5. The cultivation pot installation part 6 is formed so as to be recessed lower than the irrigation groove 3, and the bottom surface 6 a is provided with a drain hole 6 b at the lowest position on a taper deeply inclined toward the center. The drain hole 6b is formed as a hole of about 2 to 5 mm. The size of the drain hole 6b is set such that the water can be retained for a while due to the difference between the water supply amount and the drainage amount during water supply. Thereby, water is absorbed from the bottom hole 7a (see FIGS. 6 and 7) of the cultivation pot 7 and the opening 7b on the side surface in contact with the cultivation soil in the cultivation pot while the water is pooled, and water is supplied. To be. Further, an overflow hole 6c is provided on the side surface at a predetermined height from the bottom surface. The position of this overflow hole 6c is set to a position lower than the inlet from the irrigation groove to the cultivation pot installation unit 6. By doing in this way, the backflow of the water and the solution to the irrigation groove | channel 3 can be prevented, and it can prevent that the disease of soil spreads. Even if the depth of the cultivation pot setting part 6 is about 1.5 cm, it is effective, but if it is made deep as shown in FIG. 5, the contact area between the cultivation soil and the culture solution increases, and water can be supplied in a short time. Moreover, since most of the cultivation pot 7 is hidden behind the water supply panel 1 and becomes a shadow, the temperature of the cultivation pot is difficult to increase.

  Further, as shown in FIG. 2, the bottom irrigation water supply panel 1 is provided with a ventilation through hole 10 in a region excluding the vicinity of the cultivation pot installation portion 6 and the vicinity of the irrigation groove 3. The ventilation through-hole 10 is disposed so as to be located at the center between the adjacent cultivation pot setting parts 6, and prevents the lower part of the seedling from being steamed, thereby preventing the occurrence of disease. In addition, if a mesh is attached to the through-hole 10 for ventilation, it is convenient to disinfect pests hidden behind the leaves by spraying agricultural chemicals from the lower surface of the water supply panel 1.

  The bottom irrigation water supply panel 1 is formed by pressing a rectangular plate-like panel 2 having a predetermined width, length and thickness, such as water-resistant polypropylene, polyethylene terephthalate, synthetic resin material such as foamed polystyrene, or synthetic paper. And molded. At this time, the irrigation groove 3, the cultivation pot setting portion 6, the drain hole 6b, the ventilation through hole 10, the drip receiving groove 9 and the like are integrally formed. Even if a biopolymer, a biodegradable polymer, or the like is used as the material of the other panel 2, it does not matter. In addition, the panel material must be strong enough to withstand the weight of the cultivation pot 7 and the water supply tube 4 containing the cultivation soil.

  Next, the cultivation pot 7 will be described in detail mainly with reference to FIGS. The cultivation pot 7 placed on the cultivation pot installation unit 6 has a bowl-shaped structure in which the trunk and the bottom are integrally formed and the upper part is opened, and a drain hole 7b is provided on the bottom surface 7a, and is erected from the bottom surface 7a. The side wall is provided with a irrigation hole 7c (FIG. 6) or a slit 7d (FIG. 7). The hole 7c is provided at a predetermined height position on the side wall, and the slit 7d is provided continuously from the bottom surface to a predetermined height position on the side wall. These holes 7c or slits 7d enable rapid irrigation. The trunk of the cultivation pot 7 may be provided with corrugated irregularities. Further, a reinforcing flange that protrudes laterally may be formed on the upper edge of the body portion. The cultivation pot 7 is filled with soil, and seedlings to be cultivated such as strawberries are planted. Since the cultivation pot 7 has an opening, air permeability is improved and root growth is promoted. Furthermore, since the opening is exposed to light, root winding, that is, root cap, is prevented, so that seedlings can be smoothly settled after planting, and growth delay can be prevented.

  Next, the cultivation system using this bottom surface irrigation water supply panel 1 will be described in detail. The cultivation system that uses the water supply panel 1 places the cultivation pot 7 on the plurality of cultivation pot installation parts 6 provided on the water supply panel 1, connects the water supply tubes 4 to each dropper 5, and connects the water supply tubes 4. The culture plant and the water supply solution are intermittently flowed from the dropper to the irrigation groove 3 and controlled so as to be supplied from the irrigation groove 3 to the cultivation pot 7, so that the plant planted in the cultivation pot 7 is grown and cultivated. Conventional hydroponics with bottom-side water supply basically does not use soil, but cultivates flowers and vegetables artificially under aggressive control with a culture solution containing nutrients in water. On the other hand, the intermittent bottom irrigation water supply cultivation system of the present invention uses a pot filled with soil, and water supply is performed by irrigation from the bottom intermittently when necessary to avoid root rot. is there. In the present invention, the amount of the culture solution to be supplied is calculated from the size (cross-sectional area) of the cultivation pot setting portion 6, the depth of the solution, and the drainage speed. However, the amount of the culture solution is not wasted, so that the waste of the culture solution is eliminated, and the amount of the culture solution used can be greatly reduced.

  In this cultivation system, as shown in FIG. 3, it is possible to connect and use a plurality of water supply panels 1 of FIG. In FIG. 3, three water supply panels 1a, 1b, and 1c are used with their side ends connected to each other. The water supply tube 4 is arranged across a plurality of water supply panels 1, and in FIG. 3, four polyethylene water supply tubes 4 are arranged so as to straddle the three water supply panels 1 a, 1 b, and 1 c. A ball valve 11 is attached to one end of the water supply tube 4, and a flushing valve 12 for discharging residual liquid is attached to the other end. Further, it is convenient to provide a valve in the middle of the water supply tube 4 because the previous liquid supply can be stopped.

  In this cultivation system, as shown in FIG. 8, the water supply panel 1 is used by being placed on an elevated floor base 8 having a predetermined height. In this case, a drainage receiver is provided so as to cover the lower side of the water supply panel 1. If 13 is provided and used, weeds that grow under the gantry can be reduced. The drainage receptacle may be a simple one using a synthetic resin sheet as shown in FIG. Specifically, a sheet with an inclination so that the cross-section is a triangular bag shape is stretched under the elevated floor base 8, and a straight pipe 14 or the like that overlaps the apex of the triangle is inserted. Allow leaked water to drain from the edge of the seat. When such a drain receiver 13 is added, soil and surplus water are prevented from spilling under the water supply panel 1, thereby reducing the weeds that grow, preventing the weed seeds from entering the cultivation pot 7, and the weeds as pests. It can be prevented from becoming a generation source.

  The elevated floor base 8 can be used by placing only one water supply panel 1 or connecting a plurality of water supply panels 1. The water supply pump for sending the supply liquid to the water supply tube 4 may be simple when the water supply panel 1 is small or used in a home gardening or the like. In addition, in the case of large-scale cultivation in which a large number of water supply panels 1 are connected, devices such as a water tank and a water supply pump are provided as water supply means. Can save you money.

  In this cultivation system, irrigation can be automatically performed by setting a program in a solenoid valve with a timer. This program is set so that the amount of water can be controlled according to the season, weather, growth stage, and amount of water required for each item.

  According to this cultivation system, the material cost of the water supply panel 1 itself is low and the molding process is simple, so the installation price of the cultivation system is extremely low. Moreover, the amount of the culture solution to be used does not always circulate the culture solution filled in a large tank as in hydroponics, but from the irrigation groove 3 formed in the water supply panel 1 to the cultivation pot installation unit 6. Also, it is sufficient to flow the culture solution to such an extent that the bottom surface 7a of the cultivation pot 7 is temporarily immersed. Furthermore, since it is only necessary to supply water intermittently, a large-scale circulation device is not required, and no electricity bill is required.

  The embodiments of the present invention have been described above with reference to the drawings. By using a water supply panel for intermittent bottom irrigation as shown above, an inexpensive panel and a cultivation pot are supplied, so that the equipment cost is reduced and the culture medium to be used can be reduced and maintained. It is possible to provide an economical cultivation system that is inexpensive.
