Description

  The present invention is a plant cultivation stick that can be widely used for plant cultivation applications such as a column supporting plants and a connecting material for coupling the columns to each other, and can also be used as a scale for various positioning in plant cultivation. It relates to materials.

  The vines and stems of vines such as pepper can be wound around the support without slipping downward, and the binding material is prevented from slipping off when the plant stem is attached to the support. As a plant cultivation prop a configured to allow the plant to grow normally upward, a hooking projection b as shown in FIGS. 22 to 23 is projected in a discontinuous state in the length direction of the prop. There is provided a discontinuous protrusion row c provided on the outer surface d of the support column.

  The support column a including the discontinuous protrusion row c was functionally superior in that it can stably support plants, but constitutes a plant cultivation shelf such as a pepper shelf as shown in FIG. In some cases, it is desirable to be able to perform the work accurately and efficiently. For example, when each column a is erected, an operation to make the piercing length constant when piercing the lower end portion e of each column a into the ground f and an operation to set the interval between the columns a to be constant are performed. It would be desirable to be able to do it accurately and efficiently. Further, when the columns are connected to each other by the connecting material g, it is desirable that the operation of setting the height of the connecting portion of each column a by the connecting material g to be constant can be performed accurately and efficiently. Also, the net j is attached so as to cover the outer surface of the column columns h arranged side by side (FIG. 24), and rain is prevented so as to cover the upper part of the column frame body k constructed by connecting the columns to each other with the connecting material g. When covering the sheet m (FIG. 25), it is desirable to be able to accurately and efficiently perform the work of aligning the lower end n of the net j and the lower end p of the rain avoiding sheet m in a horizontal state. Furthermore, it is desirable that these operations can be performed accurately and efficiently when setting the ridge width as required or setting the interval when planting plants.

  However, since the conventional struts a with discontinuous protrusion rows are not provided with any scale, there is a problem that it is difficult to meet such requirements.

  This invention is developed in view of this conventional problem, and makes it a subject to provide the rod for plant cultivation which can improve the utility value on plant cultivation based on providing a ruler function. Is.

In order to solve the above problems, the present invention employs the following means.
That is, the bar material for plant cultivation according to the present invention is provided with discontinuous protrusion rows in the length direction on the outer surface of the rod material, and is located on the side of the discontinuous protrusion row and is graduated on the outer surface of the bar material. The discontinuous protrusion row is a catch of plant stems and vines, and prevents the binder from slipping when the plant stem is bound to a rod. The hook projections that are hooked are projected in a discontinuous state in the length direction of the bar, and the scale projections are projected on the smooth outer surface of the bar at regular intervals in the length direction of the bar. Thus, a gap is provided between the scale protrusion and the discontinuous protrusion row.

  The gap can function as a drainage gap for allowing rainwater adhering to the outer surface of the bar to flow down. In this case, the width of the drainage gap is set to 1 mm or more.

  In the case where the rod for plant cultivation is configured as a column, a linear coupling member that connects the columns can be brought into contact with the outer surface of the smooth rod, and the coupling member in a corresponding contact state is It is preferable that the scale protrusion can be supported from below.

  The scale protrusion may be formed in a long node shape in the circumferential direction of the bar.

  When the discontinuous protrusion rows are provided at an angle of 90 degrees in the circumferential direction of the bar, the scale protrusions are preferably provided on the smooth outer surface of the bar between adjacent discontinuous protrusion rows.

  The surface of the scale protrusion is preferably formed in a spherical shape.

The present invention has the following excellent effects.
(1) The bar according to the present invention is positioned on the outer surface of the bar on the side of the discontinuous protrusion row provided in the length direction, and the scale protrusions protrude at regular intervals in the length direction of the bar. It is installed.
Therefore, the bar according to the present invention can be wound without causing the stems and vines of the plant to slip downward, and has a function of preventing the binder from binding the plant stems. The scale projections can be used as a ruler as well as widely used for plant cultivation, such as as a support or as a connecting material for connecting the supports. And by the ruler function, the work of setting the piercing length to the ground when standing uprights and the setting interval of the pillars, the work of setting the connection height when connecting the pillars with the connecting material, Plant cultivation, such as work to align the lower end of the net attached to cover the outer surface of the juxtaposed support columns and the rain avoidance sheet horizontally, and further to set the interval when planting plant seedlings The above various positioning operations can be performed accurately and easily.

(2) Since a gap that can also function as a drainage gap is provided between the scale protrusion and the discontinuous protrusion row, when the bar is used as a support, it adheres to the outer surface of the bar It is possible to smoothly flow down the rainwater toward the ground through the gap, and it is possible to prevent damage to the bar due to rust generation inside the bar due to deterioration of the outer surface of the bar.

(3) Further, since the scale protrusions are projected on the smooth outer surface of the bar at regular intervals in the length direction of the bar, for example, when connecting the struts with the connecting member, The smooth outer surface of the bar can be contacted stably, and in this contact state, the connecting member can be supported from below by the scale protrusion. Therefore, when the connecting material is bound to the support column, the connecting material is stably fixed to each support column without sliding down at the required height position set by the scale protrusion.

(4) By forming the scale protrusion in a spherical shape, the scale protrusion is not easily damaged. In addition, dirt is hardly attached to the scale protrusion, and even if dirt or the like is attached, it is easy to remove. In addition, even if a hand touches the scale protrusion, it is hard to get injured and is highly safe.

The struts 1a, 1a facing each other at an interval of 60 cm are erected with their upper end sides 27, 27 in an intersecting state. Prior to constructing the support frame 2, pepper seedlings are planted in the cocoon 26 at an interval of about 60 cm, for example. The setting of the heel width, the interval between the support posts, and the interval between the pepper seedlings can be easily set by using the bar 1 as an object difference.

  The support 1a is erected such that the smooth bar outer surface 12 between the adjacent discontinuous protrusion rows 11, 11 faces outward as shown in FIG. 5 (A), and the lower end portion 29 is the flange 26. This is carried out by piercing the ground 31 along the side surfaces 30 and 30 (FIG. 1) in the length direction. This piercing length is set to, for example, about 30 cm so that the scale protrusion 13 a located at the lowermost end is in contact with the ground 31. In this state, the crossing portion 32 (FIG. 5B) on the upper end side of the left and right columns 1a, 1a is bound by the binding material 33 as shown in FIG. 1, and the upper end protruding portion 35 having a V shape is formed. The bar 1 as the upper connecting member 1b1 extending horizontally is inserted at the bottom of the upper member, and the upper connecting member 1b1 is bound to the intersecting portion 32 of the left and right columns as shown in FIG. The upper connecting member 1b1 has the same configuration as that of the support column 1a, and its length is set to 270 cm as described above.

  In the upper and lower intermediate portions of the column rows 36 and 36 that are arranged side by side on the left and right sides of the rod 26, the columns are connected to each other by a bar 1 as an intermediate connecting material 1b2. The intermediate connecting member 1b2 is also set to a length of 270 cm as described above, and the height of the connecting portion of the intermediate connecting member 1b2 is as shown in FIGS. 5 (A) and 5 (C). 31 is set to the height of the second scale projection 13b from the scale projection 13a in contact with 31.

  Thus, as shown in FIGS. 6 to 7, the intermediate connecting member 1b2 can contact the smooth rod outer surface 12 without contacting the discontinuous protrusion rows 11 and 11 existing on both sides of the scale protrusion 13b. In this state, the intermediate connecting member 1b2 is supported from below by the second scale projection 13b. As shown in FIG. 1, the intermediate connecting member 1b2 is connected to the column 1a by the binder 33. Worn. As a result, the intermediate connecting member 1b2 is in a horizontal state, and in this state, the intermediate connecting member 1b2 is securely fixed to each column 1a without sliding down. Thus, since the intermediate coupling member 1b2 can be disposed in a horizontal state, the support frame 2 can be configured stably.

  The pepper shelf 23 is configured by covering the outer surfaces of the left and right column arrays 36, 36 of the column frame 2 thus configured with a net 39 and fixing the net 39 to the column 1a as appropriate. At this time, the lower end 40 of the net 39 is set so as to be at a position of about 30 cm when viewed from the ground 31 in the inclination direction of the column 1a as shown in FIG. This position setting can be easily performed using the scale protrusions 13 provided on the respective pillars 1a as marks. As a result, the lower ends 40 of the nets 39 are aligned in a horizontal state.

  FIGS. 9-10 (A) shows the support | pillar frame 2 comprised in order to grow a tomato, Each support | pillar 1a which comprises this support | pillar frame 2 consists of the said bar 1, and is a discontinuous protrusion. The upper end portion of the column 1a as a linear bar provided with the row 11 and the scale protrusion 13 is connected to both lower ends 42, 42 of the arch-like portion 41 by means such as insertion connection. In addition, the discontinuous protrusion row | line | column 11 and the said scale protrusion 13 may be provided only in the both lower end part of the said arch-shaped part 41, or the full length. 9A to 10A show a case where the discontinuous protrusion rows 11 are provided only at both lower end portions of the arch-shaped portion 41. FIG.

  The column 1a is in an upright state when a lower end portion (for example, a portion of about 30 cm) 29 is pierced into the ground 31 with the scale protrusion 13 as a mark. Then, when the rain avoidance sheet 45 is covered so as to cover the upper part of the support frame 2, the lower end 46 of the rain avoidance sheet 45 is aligned in a horizontal state with the scale protrusion 13 as a mark. In FIG. 9, the rain avoidance sheet 45 is indicated by a chain line for convenience. Then, as shown in FIG. 10, the string-like support material 47 that supports the stem of the tomato is used as a linking member 1b3 with the scale protrusion 13 provided on the connecting member 1b3 at the upper end of the bar 1 as a mark. For example, it can be attached by binding.

  11 to 12 show a case where the column 1a is erected in a vertical state, not in an inclined state. In FIG. 12, the binder is omitted. In the same manner as described above, the column 1a is in a standing state when a lower end portion (for example, a portion of about 30 cm) 29 is pierced into the ground 31 with the scale protrusion 13 as a mark. Further, as shown in FIGS. 12 to 13, the connecting material 1b for connecting the columns to each other is moved downward from the scale protrusion 13a in contact with the ground 31 by, for example, the second scale protrusion 13b and the third scale protrusion 13c. In this state, it is brought into contact with the outer surface (bar material outer surface) 12 of each strut 1a, and in this state, the connecting material 1b is bound to each strut 1a with a binding material 33. As a result, the connecting member 1b is in a horizontal state and is securely fixed to each column 1a without sliding down in this state, and the column frame 2 in a vertically standing state is configured.

  In the bar 1 as the column 1 a constituting each column frame 2, as shown in FIG. 3B, a drain gap 19 is provided between the scale projection 13 and the discontinuous projection row 11. As shown by the arrows in FIG. 6, the rain water adhering to the bar outer surface 12 can smoothly flow down toward the ground, resulting in deterioration of the bar outer surface. It is possible to prevent damage to the bar due to rust generation inside the bar. Further, since the surface 16 of the scale projection 13 is formed in a spherical shape, it is difficult for the scale projection 13 to be caught even when dirt flows down from above during rainfall.
