Description

  The present invention relates to a rock for plant growth for growing plants such as plants.

  In nature, plants can grow on the surface of rocks. When a plant grows on rocks, the surface of the rock can be cleaved by weathering, and the crevice can spread over a long period of time, and sand generated by weathering, soil carried by the wind, or dead leaves can be used as soil. accumulate. If the soil accumulates on the surface of the rock, the wet state by rainwater can be maintained for a predetermined period. There are cases where seeds are carried on the surface of such rocks by wind or birds and plants grow.

  The state in which the plant grows on the surface of the rock in this way presents a natural landscape and is valuable for ornamental purposes.

  Patent Document 1 discloses a bonsai using a coral reef in which a plurality of holes penetrating from the surface to the bottom surface are provided in a coral reef similar to rocks, and plant seedlings germinated in the hole are planted.

JP 2004-267049 A

  By the way, the bonsai using the coral reef shown in Patent Document 1 is provided with a plurality of holes penetrating from the surface of the coral reef limestone to the bottom and a hole branching from the hole and opening at the bottom, and the plant sprouted in the hole I try to plant through the roots.

  However, if the roots of the plant are simply passed through the through holes formed in the coral reef limestone, the liquid will flow out without remaining in the through holes even if the nutrient liquid is supplied. Will be unable to supply.

  Therefore, as described above, a hole penetrating from the surface to the bottom surface is made in the coral reef, and the coral reef is placed on the soil put in the flower pot. The roots of the plants are passed through the holes formed in the coral reef, and the roots are stretched on the pot soil.

  However, according to such a configuration, coral reef limestone is not sufficient for growing plants, and it is necessary to supply nutrients such as moisture from a flower pot in which soil is put. Moreover, it is not preferable to place the coral reef limestone on the plant pot soil to grow the plant, because the appearance will be greatly different from the natural state where the plant is directly growing on the coral reef limestone. There is.

  This invention is made to be able to grow a plant on the surface of the rock for plant growth without using a flower pot by allowing the rock for plant growth to retain nutrients for growing the plant. It is to provide rocks for plant growth.

This invention is a rock for plant growth for growing plants,
The plant growth rock has one end opened on the surface and the other end closed, and a plurality of liquid retaining holes capable of holding liquid for nutrients of the plant are inclined upward from the horizontal. It is a rock for plant growth characterized by being provided at an angle.

  It is preferable that at least two liquid retaining holes communicate with each other inside the rock for plant growth.

  According to the present invention, a plurality of liquid retaining holes that can hold a liquid serving as a nutrient for a plant inside with one end opened on the surface and the other end closed are inclined upward from the horizontal in the rock for plant growth. Provided at an angle.

  Therefore, if the plant is held on the surface of the rock for plant growth, the root of the plant grows and part of it enters the liquid retaining hole, and absorbs the liquid serving as the nutrient retained in the liquid retaining hole, The other part absorbs the wet surface liquid on the surface of the rock, so that the plant can be grown well on the surface of the rock for plant growth.

  Moreover, since the liquid retaining hole is provided in the plant growth rock at an angle inclined upward from the horizontal, the liquid serving as a nutrient can be stored in the liquid retaining hole, thereby reducing the liquid supply frequency. In addition, when the liquid is supplied from above the rock for plant growth, the liquid easily enters the liquid retaining hole.

Sectional drawing of the rock for plant cultivation which shows one embodiment of this invention. Explanatory drawing which shows the state which the plant landed on the surface of the rock for plant cultivation.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a cross-sectional view of a plant-growing rock 1. The plant-growing rock 1 is made of a porous material having an uneven surface such as natural volcanic rock, and the bottom surface 2 is formed in a substantially flat surface. As a whole, a desired shape such as a trapezoidal shape or a mountain shape is obtained.

  Note that the plant-growing rock 1 may be a natural volcanic rock or other natural volcanic rock or the like formed of a material having an uneven surface in a desired shape. The bottom surface 2 is a substantially flat surface so that it can be installed with good stability. However, the bottom surface 2 may not be a flat surface but may have an uneven shape.

  In the plant-growing rock 1, a plurality of liquid retaining holes 3 having one end opened on the surface and the other end closed inside are formed at an angle inclined upward from a horizontal state by, for example, a drill. That is, the liquid retaining hole 3 is formed at an angle at which one end opened on the surface of the plant growing rock 1 is located above the other end closed inside. The plurality of liquid retaining holes 3 may have different diameters as well as those having the same inner diameter.

  The liquid retaining hole 3 is supplied and held with a liquid L such as water such as rain water or city water, or water containing liquid fertilizer, which serves as nutrients for a plant P (shown in FIG. 2) grown as described later. The plant P is preferably a plant that can grow even if there is a large difference between dry and wet, such as moss, rock hiba, yukinoshita, gypsophila and wind orchid.

  Since the plant-growing rock 1 has the liquid retaining hole 3, the liquid L serving as a nutrient for the plant can be stored and retained in the liquid retaining hole 3. Therefore, the liquid L supplied to the surface of the plant growing rock 1 is prevented from immediately flowing down and the plant growing rock 1 is prevented from drying out at an early stage, so that the supply frequency of the liquid L can be reduced.

  Since the liquid retaining hole 3 is formed at an angle where one end opened on the surface of the plant growing rock 1 is located above the other end closed inside, the liquid L is formed on the surface of the plant growing rock 1. When supplied by watering or rain, the liquid L may easily enter the inside from one end where the liquid retaining hole 3 is opened.

  Specifically, when the liquid retaining hole 3 is formed to be inclined, the opening shape at one end of the surface of the rock 1 for plant growth of the liquid retaining hole 3 becomes an elliptical shape including an oval shape. When the opening shape of the liquid retaining hole 3 is elliptical, the surface tension of the film of the liquid L generated at the opening of the retaining hole 3 when the liquid L is supplied by sprinkling water is the length of the liquid retaining hole 3. The axial direction and the minor axis direction are imbalanced and are difficult to maintain.

  Therefore, when the liquid L is sprinkled and supplied to the surface of the plant-growing rock 1, even if a film is formed at the opening of the liquid retaining hole 3, the supplied liquid L collides with the film, and the external Therefore, even if the liquid retaining hole 3 has a relatively small diameter, the liquid L may easily enter the inside thereof.

  In addition, since the liquid retaining hole 3 is formed to be inclined, the liquid retaining hole 3 opens in an elliptical shape on the surface of the plant-growing rock 1. The upper portion and the lower portion of the elliptical opening surface of the liquid retaining hole 3 are displaced in the front-rear direction with respect to the vertical surface. That is, on the surface of the plant-growing rock 1, the upper part of the opening surface of the liquid retaining hole 3 is positioned so as to be shifted in the front-rear direction with respect to the vertical direction with respect to the lower part.

Therefore, the inflow path of the liquid L into the liquid retaining hole 3 and the outflow path of the air in the liquid retaining hole 3 are ensured by the deviation between the upper part and the lower part of the liquid retaining hole 3. become. That is, the liquid L heavier than air mainly flows along the lower part of the inner peripheral surface of the liquid retaining hole 3 and flows into the interior, and the air in the liquid retaining hole 3 The liquid L flowing through the upper portion and flowing into the liquid retaining hole 3 is pushed out from the inside by the same amount as the amount of the liquid L.
Therefore, the liquid L supplied to the surface of the plant-growing rock 1 easily flows into the liquid retaining hole 3 by the above-described action.

  For example, if the liquid retaining hole 3 is formed with a relatively small inner diameter of about 10 mm, the liquid L supplied to the surface of the plant growing rock 1 may not easily enter the interior as described above. If the holes 3 are formed on the surface of the plant-growing rock 1 so as to have an elliptical shape, the liquid L supplied to the surface of the plant-growing rock 1 flows relatively well into the interior. It becomes possible.

  That is, in order to allow the liquid L to flow into the liquid retaining hole 3 and hold it, the inner diameter of the liquid retaining hole 3 may damage the appearance of the plant growing rock 1 or reduce the strength of the plant growing rock 1. Sometimes it is not necessary to have a large diameter.

  If the liquid retaining hole 3 is formed at an angle that is perpendicular to the horizontal plane when the plant-growing rock 1 is installed, the liquid retaining hole 3 depends on the irregular shape of the surface of the plant-growing rock 1. Since the opening surface of the liquid is likely to be a circular shape or a shape close to a circular shape, the liquid L may not easily enter the inside.

  Therefore, the liquid retaining hole 3 is preferably formed to be inclined so as not to be perpendicular to the horizontal plane when the plant-growing rock 1 is installed. However, the liquid retaining hole 3 may be formed vertically as long as the inner diameter dimension of the liquid retaining hole 3 can be formed so that the liquid L supplied from above can easily flow in.

  Further, depending on the uneven shape on the surface of the plant-growing rock 1, even when the liquid retaining hole 3 is formed perpendicular to the horizontal plane, the opening shape of the liquid retaining hole 3 may be elliptical. In such a case, the liquid retaining hole 3 may be formed perpendicular to the horizontal plane.

  That is, in this embodiment, the liquid retaining hole 3 may be formed at an angle at which the liquid L supplied from above can be stored inside, that is, at an angle inclined upward from the horizontal. If the opening surface of the hole 3 is formed to have an elliptical shape, the liquid L can be satisfactorily flowed into the inside even when the inner diameter dimension of the liquid retaining hole 3 is relatively small.

  Of the plurality of liquid retaining holes 3 formed in the plant growing rock 1, for example, two or three liquid retaining holes 3 are formed so as to communicate with each other inside the plant growing rock 1. If two or three liquid retaining holes 3 communicate with each other, when the liquid L in one liquid retaining hole 3 decreases, the liquid L in the other liquid retaining hole 3 flows into the liquid retaining hole 3.

  Therefore, when the root r of the plant P grows in one liquid retaining hole 3 out of the two or three liquid retaining holes 3, the liquid L in the other liquid retaining hole 3 is in the liquid retaining hole 3. For example, the root r of the plant P can absorb the liquid L in the other liquid retaining holes 3, so that the supply frequency of the liquid L can also be reduced.

  In addition, as shown in FIG. 2, the root r of the plant P enters the other liquid retaining hole 3 from one communicating liquid retaining hole 3 and grows. Therefore, compared to the case where the root r of the plant P simply enters the single liquid retaining hole 3, the plant P can be strongly stretched in the liquid retaining hole 3 of the plant-growing rock 1, so that the plant P is detached by a strong wind or the like. It can be grown in a stable state without any problems.

  Although the case where two or three liquid retaining holes 3 are communicated has been described, four or more liquid retaining holes 3 may be communicated.

  When growing the plant P using the plant-growing rock 1 having the above-described configuration, first, the plant P is held on the surface of the plant-growing rock 1 so as to be difficult to move by a holding member (not shown) such as an elastic rubber band or string. Keep it. And the liquid L, such as water and a liquid fertilizer, is regularly sprayed with respect to the whole surface from the upper direction of the rock 1 for plant cultivation.

  Part of the liquid L supplied to the surface of the plant-growing rock 1 accumulates on the uneven surface, moisturizes the surface without accumulating, and further penetrates from the surface into the interior and is supplied to the plant P, and the rest The liquid L enters and is stored in the liquid retaining hole 3 having one end opened on the surface of the plant-growing rock 1.

  The liquid retaining hole 3 is provided at an inclined angle so that one end opened on the surface of the plant-growing rock 1 is located above the other end located inside. Therefore, the liquid L supplied by sprinkling water from above the plant-growing rock 1 may easily enter the liquid retaining hole 3 as described above, and the liquid L flowing into the liquid retaining hole 3 is Since the liquid retaining hole 3 is inclined upward from the horizontal, the liquid retaining hole 3 is reliably stored in the interior as compared with the case where the liquid retaining hole 3 is inclined horizontally or downward.

  The plant P held on the surface of the plant-growing rock 1 grows by contact with the liquid L moistened on the surface of the plant-growing rock 1 and the liquid L stored in the liquid retaining hole 3, and further new The root r grows by rooting or the like, and the root r settles on the surface of the plant-growing rock 1 or grows while fixing on the surface and enters the liquid retaining hole 3 where the liquid L is stored.

  When the plant P settles on the surface of the plant-growing rock 1 in this way, the plant P is supplied to the surface of the plant-growing rock 1 and accumulated on the surface, or the liquid L or the liquid retaining liquid whose surface is moistened. The liquid L accumulated in the hole 3 is absorbed as nutrients and grows.

  If the root r of the plant P is fixed on the surface of the plant-growing rock 1 or in the liquid retaining hole 3, the holding member holding the plant P is removed.

  The liquid L that accumulates on the surface of the plant growth rock 1 or wets the surface dries in a relatively short time, but the liquid L stored in the liquid retaining hole 3 remains for a relatively long time. Moreover, the supply frequency of the liquid L with respect to the plant P can be reduced.

  In other words, since the plant-growing rock 1 is difficult to dry as a whole by the liquid L stored in the liquid retaining hole 3, the plant P fixed on the plant-growing rock 1 can be grown in a stable state.

  The root r of the plant P fixed on the surface of the plant-growing rock 1 enters the liquid retaining hole 3 and adheres to the inner surface of the liquid retaining hole 3. In addition, since the plurality of liquid retaining holes 3 communicate with each other inside the plant-growing rock 1, the root r of the plant P that has entered one liquid retaining hole 3 enters the other liquid retaining hole 3. To settle.

  As a result, the root r of the plant P strongly adheres to the plant-growing rock 1 and is in a stable state that does not easily fall over, which also facilitates the growth of the plant P.

  The root r of the plant P not only enters the liquid retaining hole 3 and is immersed in the liquid L, but also grows by attaching to the surface of the plant growing rock 1.

  Therefore, the root r that has entered the liquid retaining hole 3 and is immersed in the liquid L cannot absorb oxygen sufficiently, but can absorb the liquid L instead. In contrast, the root r exposed on the surface of the plant-growing rock 1 cannot absorb much of the liquid L, but can sufficiently absorb oxygen because it is exposed to the outside. As a result, the plant P can absorb the liquid L and oxygen in a well-balanced manner, so that the plant P can be grown in a balanced and stable state.

  By forming the liquid retaining hole 3 in the plant-growing rock 1, the plant P can be grown without using the soil as in the conventional case. Therefore, it is not necessary to place the plant-growing rock 1 on a plant pot or the like in which the soil is put. Therefore, the plant P is grown without damaging the natural appearance of the plant P growing on the surface of the plant-growing rock 1. Can be nurtured and appreciated.
