Description

When cultivating a plant, the present invention keeps the seedling warm, prevents the seedling from being damaged by frost, or covers the seedling on the ground for the purpose of protecting the seedling from damage from wild animals such as birds and insects. The present invention relates to a seedling protective cover used in the process. The present invention also relates to a set of a seedling protection cover and a support having such a configuration.

  When cultivating plants such as agricultural crops and horticultural crops, transparent protection for the purpose of keeping the seedling warm, preventing the seedling from frost damage, or protecting the seedling from damage of wild animals such as birds and insects Covering the seedling with a cover is performed.

  As an example, what is disclosed in Japanese Utility Model Registration No. 3104682 has been proposed. For example, as shown in FIG. 21 (A), the seedling protective cover a includes a transparent cup-shaped cylindrical body b that is integrally formed of a synthetic resin and has a lower end portion of a side surface portion c of the cylindrical body b. Protrusions e for piercing deeply into the soil were formed on the circumference of d at intervals. The cylindrical body b is increased in diameter downward and formed into a tapered shape, and is shown by a chain line in FIG. 21 (B) at the top f of the cylindrical body b, and as shown in FIG. It had a configuration in which one opening g was provided. Alternatively, as indicated by a solid line in FIG. 21B, a plurality of holes h may be provided in the flat top f instead of the opening g.

  As shown in FIG. 22, the seedling protective cover a having such a structure is fixed to the ground by piercing the protrusion e into the soil j relatively deeply, and the protrusion e is caused by wind or the like. The seedling protection cover a was prevented from being skipped. The opening g and the hole h are intended to adjust the temperature and humidity inside the seedling protection cover a, and to prevent birds and insects.

  However, when such a seedling protective cover a is used, there is a case where it is difficult to pierce the protruding portion e into the soil, and there is a possibility that the pierced protruding portion e may come out, so the installation state of the seedling protective cover a is unstable. There was a problem that was easy to convert. Further, when the large opening g is provided in the top part f, even if the air permeability through the opening g is good, outside air enters the inside k of the seedling protection cover a through the large opening g. Therefore, there is a problem that the heat resistance of the seedling protection cover a is easily impaired. Further, as described above, when the seedling protection cover a is fixed to the ground j, the projecting portion e is pierced into the soil as described above. There is a problem that the water drainage inside the seedling protection cover a is impaired by the water shielding action of the plurality of protrusions e that are relatively deeply pierced into the seedling. Therefore, when the rain is heavy, a large amount of rain easily enters the inside of the seedling protection cover a through the large opening g, and the rainwater that has entered is difficult to be drained to the outside. As a result, the water level may rise in the seedling protective cover, and root rot may occur in the seedling.

  On the other hand, when a plurality of holes h are provided at the top f of the cylindrical body b as described above, there are problems relating to heat retention and air permeability as in the case where such a large opening g is provided, and a large amount of rainfall. Although there is no problem associated with the inflow of water, there is room for improvement with respect to the problem that the protruding part e is not easily pierced into the soil, and the protruding part e pierced into the soil is easily removed. In addition, since a plurality of hole portions h are provided in the flat top portion f, there is a problem that the rain water that has fallen on the top portion f cannot always be introduced satisfactorily into the cylindrical body b.

  As another embodiment of this kind of seedling protective cover, a plant covering disclosed in Japanese Patent Application Laid-Open No. 2007-43977 has been proposed. The plant covering n is made of a transparent resin. As an example, as shown in FIGS. 23 to 24, the plant covering n rises from the contact surface portion p that contacts the soil, and the inner peripheral edge q of the contact surface portion p, and A covering portion s having a side wall r that circulates along the inner peripheral edge q is provided, and the covering portion s is transparent or translucent and has a dome-shaped or bell-shaped shape. A water storage groove t that makes a round in the circumferential direction of the side wall r was provided outside the side wall r of the covering portion s. In addition, an air vent hole v was provided at the top u of the covering portion s.

  The plant covering n having such a configuration is placed on the ground m after being covered with a seedling, and then the water is stored in the water storage groove r, so that the plant covering n is the weight of the stored water. It was intended to prevent being blown by the wind. However, a large amount of weight cannot be obtained only with the water stored in the water storage groove t, and there is a problem that it is difficult to stably fix the plant covering device n to the ground j. In order to fix the fixture n to the ground j, it is essential that water is always stored in the water storage groove t. However, there is a problem in that water supply management to the water storage groove t is troublesome.

The present invention has the following excellent effects.
The seedling protection cover according to the present invention can cover a seedling and place it on the ground to keep the seedling warm and prevent the seedling from being damaged by frost, or can protect a plant from damage by wild animals such as birds and insects. Has the following excellent effects.

(1) The seedling protective cover according to the present invention is provided with an annular recess that is continuous in the circumferential direction in a portion on the upper end side of the dome portion, and a ventilation hole or a water passage hole is formed on a horizontal bottom surface of the annular recess. Since a configuration in which a functioning through hole is provided is employed, the inside of the dome can be effectively vented by the function of the through hole as a vent hole. In addition, since rainwater can be stored in the annular recess, rainwater can be smoothly introduced into the dome portion by the function of the through hole as a water passage hole. And since the seedling protective cover is placed on the ground over the seedling, the water drainage inside the dome part is not impaired.

(2) In addition, since a column insertion part for inserting the column in the vertical direction is provided on the top surface of the dome unit, the column is inserted into the column insertion unit and the lower end side portion of the column is earthed. By pushing in, the support can support the upper part of the dome. Thereby, it can prevent that the seedling protection cover in the state covered with the seedling is blown off by the wind.

(3) Since the plurality of annular concavo-convex portions forming the embankment surface portion of the annular recess and the upper and lower raised surface portions exhibit a rib action, the rigidity of the upper end side portion of the dome portion is improved. Therefore, even when the support column is closely inserted into the support column insertion portion, the upper end portion of the dome portion is not easily deformed.

(4) A horizontal collar is provided at the lower edge of the dome, and an anchor hole for inserting an anchor piece is provided in a fixing horizontal collar facing the dome so as to be bent, and the horizontal collar is bent. When providing a groove line for use, with only one of the horizontal ridges fixed to the ground with an anchor piece, the folding groove line functions as a hinge to easily open and close the seedling protective cover Can do. Thereby, watering, top fertilization, weeding, etc. can be performed on the seedling with the dome part opened.

(5) When the post insertion portion is formed with a cross-shaped cut, a post insertion portion for allowing the support column to be closely inserted in the vertical direction can be easily formed. Moreover, even if the supporting column to be inserted is relatively thick or thin, a triangular engagement protruding piece formed by the cross-shaped notch follows the thickness of the supporting column. Since it can be easily elastically deformed, the column can be easily inserted into the column insertion part. In addition, since the support can be in a state of being closely inserted into the support insertion portion, the support of the seedling protection cover by the support can be further stabilized.

(6) When the strut is provided on the surface thereof and the protrusion for catching is provided in a discontinuous state in the length direction of the strut, the strut insertion part is hooked on the catching protrusion of the strut Thus, it is possible to suppress the seedling protection cover from being lifted by the wind. In addition, when the seedling protection cover is lifted along the support, the support insertion part is caught by the hooking projection, so that the lifted state is easily maintained. In doing so, the work can be facilitated.
In particular, when the strut insertion part is configured with a cross-shaped cut, the triangular engagement protrusion formed by the cross-shaped cut in a state where the cross-shaped cut is expanded and the support is inserted. Since the tip end of the support is elastically pressed against the surface of the support column, the support column insertion portion is more reliably engaged with the hook projection.

  1-2, the seedling protective cover 1 according to the present invention is used by covering the seedling P, and is made of a transparent resin. An annular recess 6 that is continuous in the circumferential direction is provided in a portion 5 on the upper end side of the dome portion 3 that accommodates seedlings. A horizontal bottom surface portion 7 of the annular recess 6 is spaced apart in the circumferential direction. In addition, a through hole 9 that can function as a vent hole 9a or a water hole 9b is provided. Further, the top surface portion 10 of the dome portion 3 is provided with a column insertion portion 12 for closely inserting the column 11 in the vertical direction.

  In the present embodiment, the dome portion 3 is made of a thin transparent resin having a thickness of about 0.3 to 0.5 mm, and has a dome shape, a bell shape, or the like protruding upward with the lower end 2 open. The lower end 2 has a diameter of about 280 to 350 mm, for example, and a height of about 210 to 250 mm. Here, the term “transparent” includes colored and transparent as well as colorless and transparent as long as the amount of sunlight necessary for the growth of seedlings can be secured.

  More specifically, as shown in FIGS. 1 to 5, the dome portion 3 is connected to an upper end 15 of an annular pedestal side surface portion 13 that has an annular shape in plan view via an arcuate circumferential surface portion 16 protruding outward. The horizontal stepped surface portion 17 is continuously provided inward, and the spherical side surface portion 20 is continuously provided at the inner end edge 19 of the horizontal stepped surface portion 17, and the upper end edge 21 of the spherical side surface portion 20 is A protruding arc-shaped dyke surface portion 22 is continuously provided, and a horizontal bottom surface portion 7 is continuously provided inward at a lower end edge 23 of the levee surface portion 22. In addition, an inclined side surface portion 29 that inwardly slopes upward is provided at the inner edge 26 of the bottom surface portion 7, and a substantially horizontal surface portion that curves gently upward at the upper end of the inclined side surface portion 29. The lower raised surface portion 33 having a circular shape in plan view is formed by 32 being continuously provided inward. In addition, an inclined surface portion 36 that is inclined obliquely upward is provided at the inner end edge 35 of the substantially horizontal surface portion 32 of the lower raised surface portion 33, and an upward projecting circle is formed at the upper end of the inclined surface portion 36. An upper raised surface portion 40 that is gently curved upward and has a circular shape in plan view is connected via an arcuate surface portion, and the upper raised surface portion 40 constitutes the top surface portion 10 of the dome portion 3. Yes.

  And, as shown in FIG. 1 and FIGS. 4 to 5, the annular recess 6 having the horizontal bottom surface portion 7 is formed between the dike surface portion 22 and the lower raised surface portion 33, The bottom surface portion 7 is provided with the through holes 9 that can function as the air holes 9a and the water holes 9b at intervals in the circumferential direction. The through holes 9 are, for example, circular holes having a diameter of about 8 mm, and are provided at an angular pitch of 20 degrees in a plan view, for example. Thus, since the through-hole 9 is provided in the horizontal bottom face part 7, when this through-hole 9 is provided by press work, this press work can be performed stably.

  As shown in FIGS. 1 and 5, a column insertion portion for allowing the column 11 to be inserted closely in the vertical direction in the central portion of the upper raised surface portion 40 (top surface portion 10) that exhibits a circular shape in plan view. 12 is provided. For example, as shown in FIGS. 6 to 8, the strut 11 has cap members 45 having an outer diameter of about 12 mm on upper and lower ends 42 and 43 of a linear round pipe 41 having a diameter of about 11 mm and a length of about 1000 mm. The one provided with 46 is used. In this embodiment, as shown in an enlarged view in FIG. 8, four discontinuous protrusion rows 38 extending in the column length direction are substantially arranged in the circumferential direction on the outer circumferential surface 34 of the linear round pipe 41. It is provided at an angle of 90 degrees. The discontinuous protrusion array 38 is, for example, a resin-made hook having a length of about 4.6 mm, a width of about 1.2 mm, and a protrusion amount of about 0.7 mm (long in the column length direction). Are formed in a discontinuous state with a spacing of about 9.6 mm in the column length direction.

  In addition, in the present embodiment, as shown in FIGS. 1 and 5, the column insertion portion 12 is formed in a cross shape formed by combining linear cut lines 47 and 47 having a length of, for example, about 35 mm in a cross shape. It is formed with a notch 49, and the center 50 of the cross is substantially coincident with the center 51 of the top surface portion 10.

  Since the column insertion portion 12 is formed with the cross-shaped cut 49 in this way, when the column 11 is inserted through the cross-shaped cut 49, the four formed by the cut lines 47 and 47 are used. As shown in FIGS. 6 to 7, the triangular engagement protruding pieces 52, 52, 52, 52 can easily elastically deform following the diameters of the cap members 45, 46 and the linear round pipe 41. For this reason, the support column 11 can be in a state of being closely inserted into the support column insertion portion 12.

  Further, as shown in FIGS. 1 and 9, the annular pedestal side surface portion 13 has a reinforcing rib 57 having a lower end 53 opened downward and an outer surface 55 and an inner surface 56 projecting outward. Are juxtaposed in the circumferential direction at small intervals.

  As shown in FIGS. 1 and 9, the lower side portion 59 of the spherical side surface portion 20 has an outer surface 60 and an inner surface 61 projecting outward from the spherical side surface portion 20, and an upper end portion. 62 (FIG. 1) is provided with hook-like longitudinal reinforcing ribs 63 each having a hook-like shape in which the shape is gradually narrowed and provided in the circumferential direction of the spherical side surface portion 20 at a required interval (for example, at an angular pitch of 10 degrees in plan view). The lower end 64 of each bowl-shaped vertical reinforcing rib 63 is open at the horizontal stepped surface portion 17.

  In the present embodiment, as shown in FIGS. 1 and 5, a horizontal flange 66 having an outer shape, for example, a square shape in a plan view, is provided on the lower peripheral edge 65 of the dome portion 3 having such a configuration. The four corners are provided with horizontal arcuate portions 67, 67, 67, 67 having a wide circular arc shape. Of these four horizontal rod portions 67, 67, 67, 67, two horizontal rod portions (fixed horizontal rod portions) 67a, 67a facing each other with the dome portion 3 interposed therebetween are anchor members 69 shown in FIG. Anchor holes 68, 68 through which the two anchor pieces 70a, 70b are inserted are provided at a required interval, and the horizontal flange portions 67a, 67a are positioned inside the anchor holes 68, 68. Bending groove lines 71 are provided. In this embodiment, the bending groove lines 71 and 71 are provided in a state orthogonal to a straight line 72 (FIG. 5) connecting the opposed horizontal flange portions 67a and 67a, and both ends 73, 73, 73 thereof. , 73 are opened at the peripheral edge 75 of the horizontal flange portions 67a, 67a, as shown in FIGS.

  In the present embodiment, one of the anchor pieces 70a, 70b constituting the anchor member 69 is formed longer than the other 70b. This is because, after the lower end portion 70a1 of the long anchor piece 70a is inserted into the one anchor hole 68a and pierced into the ground 79, the anchor member 69 is moved around the axis L of the anchor piece 70a, and the arrow in FIG. This is because it can be appropriately rotated as indicated by F1 and F2, and the other anchor piece 70b is easily positioned and inserted into the other anchor hole 68b.

  Further, as shown in FIGS. 1 and 5, a plurality of the seedling protection covers 1 are provided on the other two horizontal heel portions (horizontal heel portions for bundling) 67b and 67b facing each other with the dome 3 interposed therebetween. As shown in FIG. 11, a binding hole 77 is provided for binding and integrating the whole (for example, five sheets) with a binding tool 76 such as a resin-coated iron wire.

  The seedling protective cover 1 having such a configuration can be formed by vacuum molding using a transparent resin such as polyethylene terephthalate, polyester resin, polyolefin resin, or polyvinyl chloride resin. The seedling protective cover can also be formed by injection molding, blow molding, or the like.

  However, as shown in FIG. 6, the seedling protection cover 1 having such a configuration is placed on a seedling (not shown) and the horizontal ridge 66 is placed on the ground 79, so that the temperature inside the seedling protection cover 1 is increased. The humidity can be adjusted, the seedling can be kept warm and the seedling can be prevented from being damaged by frost, and the seedling can be protected from damage of wild animals such as birds and insects.

  The seedling protection cover 1 is used by covering the seedlings in this way, and the anchor pieces 70a, 70b of the anchor member 69 are provided in the anchor holes 68, 68 of the fixing horizontal ridge portions 67a, 67a. The anchor pieces 70a and 70b are pierced into the soil by being inserted. As a result, the seedling protective cover 1 can be fixed to the ground 79. After the anchor pieces 70a and 70b are pierced into the soil as described above, the horizontal ridge portions 67, 67, 67 and 67 are appropriately covered with soil in order to improve the stability of the seedling protection cover 1 installation. Good.

  This can stabilize the state of installation of the seedling protective cover 1, but the seedling protective cover 1 is thin and lightweight, and thus may be blown away by the wind. When there is such a fear, as shown in FIG. 6, the cross-shaped cut 49 provided in the top surface portion 10 is used in order to more reliably fix the seedling protection cover 1 to the ground 79. The column 11 is closely inserted in the column insertion portion 12 in the vertical direction, and the lower end portion 80 of the column 11 is pushed into the ground 79 by about 20 to 30 cm to bring the column 11 upright.

  In the present embodiment, as shown in FIG. 1, the upper and lower raised surface portions 40 and 33 and the levee surface portion 22 are provided on the upper end portion 5 of the dome portion 3. The upper end portion 5 is reinforced by the formation of a plurality of annular concavo-convex portions. Therefore, even if the seedling protection cover 1 is formed thin, it is difficult to deform the upper end portion 5 when the support 11 is inserted through the cross-shaped cut 49. Further, as described above, since the flange-like vertical reinforcing rib 63 is provided on the spherical side surface portion 20 of the dome portion 3, the dome portion 3 is hardly deformed as a whole.

  In this way, the support column 11 is closely inserted into the support column insertion portion 12 and the lower end portion 80 of the support column is pushed into the ground 79, so that the upper end portion 81 of the support column 11 is the upper end of the dome portion 3. It protrudes above 82. The upper end portion 81 of the support column 11 erected in this way supports the top surface portion 10 of the dome portion 3, and the support column 11 supports the dome portion 3 at its central portion. In addition, the risk of the seedling protection cover 1 being blown off by the wind can be avoided. If necessary, the support 11 can also be used as a seedling splint by connecting the seedling to the support 11. Thus, when the support | pillar 11 is used also for support of a plant, if the said seedling protection cover 1 is lifted along the support | pillar 11 after a seedling grows and it removes from a support | pillar, the support | pillar 11 supports a grown plant after that. Will also play a role.

  For example, as shown in FIG. 12, the attachment procedure of the support 11 to the seedling protection cover 1 is made close to the seedling (not shown), and the portion 80 on the lower end side of the support 11 is pushed into the ground 70. The upper portion 83 of the column portion 11a protruding upward is inserted upward from the inside of the dome portion 3 into the column insertion portion (cross-shaped cut 49) 12, and thereafter, arrows F3 and F4 in FIG. The seedling protection cover 1 can be lowered along the support 11 as shown in FIG. 6, and finally the horizontal ridge 66 can be placed on the ground 70 as shown in FIG. In this case, the seedling protection cover 1 may be lowered downward after the seedling is connected to the support 11 as necessary. Alternatively, as shown in FIG. 13, with the seedling protection cover 1 placed on the seedling and the horizontal heel part 66 placed on the ground 70, the lower end portion 85 of the support 11 is connected to the support insertion part (cross-shaped notch 49). 12 may be inserted from top to bottom, and finally, the lower end portion 80 of the column 11 may be pushed into the ground 70 as shown in FIG.

  In the state where the seedling protection cover 1 is covered with the seedling in this way, the through hole 9 provided in the horizontal bottom surface portion 7 of the annular recess 6 functions as a vent hole 9a. The inside 85 can be ventilated, and the temperature and humidity in the seedling protective cover 1 can be adjusted. Since the vent hole 9a is thus provided in the upper end portion 5 of the dome portion 3 and also in the horizontal bottom surface portion 7, as shown by the arrow in FIG. The inside 86 of the dome part 3 can be effectively ventilated, for example, the moisture having risen can be smoothly discharged to the outside.

  Further, when it rains, the through hole 9 functions as a water passage hole 9b, and as shown in FIG. 14, the rain flows down the surface 5a of the upper end portion 5 of the dome portion 3 to form the annular shape. After being stored in the recess 6, the stored water is introduced into the interior 86 of the dome portion 3 by being dropped at the through hole 9. Thereby, watering to the surrounding part of a seedling can be performed effectively. The seedling protection cover 1 is installed by placing the horizontal ridge 66 on the ground 79, so that the water inside the seedling protection cover 1 is good.

  When watering, top fertilization, weeding, etc. are performed on the seedling in a state where the support 11 is inserted, the anchor members 69, 69 for fixing the fixing horizontal rod portions 67a, 67a are removed, As shown in FIG. 15, the seedling protection cover 1 can be lifted along the support 11 to perform these operations. Thereafter, the seedling protection cover 1 is lowered along the support 11, and the fixing horizontal rod portions 67 a and 67 a are fixed to the ground 79 by the anchor member 69.

  In a state in which the column 11 is not inserted, as shown in FIG. 16, only one of the opposing fixing horizontal rod portions 67a and 67a is fixed to the ground 79 by the anchor member 69. Thus, by opening the seedling protection cover 1 with the folding groove line 71 functioning as a hinge, watering, topdressing, weeding, etc. can be performed on the seedling.

  In the present embodiment, as shown in FIG. 8, a discontinuous protrusion array 38 extending in the length direction of the column is provided on the surface 91 of the column 11 (for example, an angle of about 90 degrees is placed in the circumferential direction). Therefore, as shown in an enlarged view in FIG. 17, the triangular engagement protrusion of the column insertion portion 12 is shown in a state in which the column 11 is inserted through the column insertion portion 12 in the vertical direction. When the inner edge portion 84 of the piece 52 is caught by the catching projection 44 of the discontinuous projection row 38, it is possible to suppress the seedling protection cover 1 from being lifted by the wind. Further, when the seedling protective cover 1 is lifted along the support 11 when watering or topdressing the seedling, it can be lifted by elastic deformation of the engaging protruding piece 52, and in the lifted state, as shown in FIG.

  Furthermore, the support | pillar penetration part 12 can also be comprised as the circular hole 90, as shown in FIG. In the case of such a configuration, when the pillar 11 is used with the cap members 45 and 46 attached to the upper and lower ends of the linear round pipe 41 as shown in FIGS. The diameter is set so that the cap members 45 and 46 can be easily passed. In the case of such a configuration, the straight circular pipe 41 is loosely inserted into the circular hole 90 in a state where the lower end portion 80 of the column 11 is pushed into the ground 79. The diameter of the circular hole 90 may be larger than the diameter of the column 11 as long as it can be prevented from being blown.

(2) By providing a perforated cut line on the top surface portion 10 as appropriate, the post insertion portion 12 having a circular shape or a cross shape can be formed by separating the cut line.

(3) The fixing horizontal flange portions 67a and 67a may be provided in a state of being opposed to each other with the dome portion 3 interposed therebetween, or may be provided at an appropriate angle such as 120 degrees and spaced in the circumferential direction. . Further, there may be one anchor hole 68 provided in the fixing horizontal flange portion 67a.

(4) The length of the column 11 is such that at least the portion 81 on the upper end side of the column 11 is inserted in the vertical direction through the column insertion portion 12 and the portion 80 on the lower end side is pushed into the ground. It is necessary to set so as to protrude above the upper end 82 of the dome part 3. In the case where the support 11 is to exhibit the plant support function even after the seedling protection cover 1 is removed from the support 11, a support having a length suitable for supporting the plant may be used.

(5) The seedling protection cover 1 according to the present invention is inserted in the vertical direction through the column insertion portion 12 without using the anchor member 69, and the lower end portion 80 is pushed into the ground. Only the upper portion of the dome portion 3 may be supported by only the support column 11 in the state.

(6) The seedling protection cover 1 according to the present invention may not be provided with the horizontal ridge portion 66 at the lower end periphery of the dome portion 3.

(7) The dome portion 3 may have a peripheral surface portion formed in a polygonal shape such as a quadrangle, a pentagon, or a hexagon.

(8) When the fixing horizontal flange portion is provided, the bending groove line 71 may be omitted.

(9) The through-hole 9 provided in the horizontal bottom surface portion 7 of the annular recess 6 has a plurality of two or more as long as the stored water can be introduced into the interior 86 of the dome portion 3 as required. What is necessary is just to be provided.

(10) In the case where the strut 11 is provided with the protrusions 44 for catching on its surface 91 in a discontinuous state in the strut length direction, the protrusions 44 are adjacent in the circumferential direction in FIG. The protrusions 44 arranged in the circumferential direction may be provided so as to be displaced in the vertical direction.
