Abstract

PURPOSE:To plant a tree in a state where natural appearance of a standing tree is kept by putting a root put of the tree on a specific bottom plate-like anchor and tying a root pot of the tree and the bottom plate-like anchor with a string-like member and burying the root pot in a hole for planting. CONSTITUTION:A bottom plate-like anchor 5 to which a stabilizing plate 4 projected outside in the direction of diameter is attached is arranged on the bottom 3a of a hole 3 for planting. A root pot 2 of a tree 1 for planting is put on the bottom plate-like anchor and the root pot and bottom plate-like anchor are integrally fixed with a string-like member 6 and the root pot is buried in the hole for planting.

Since it takes about a year, at least during that period, the trunk was supported by a torii-shaped auxiliary strut.

風情に劣る等の不都合がある。However, since the above-mentioned auxiliary columns require a large-area installation surface around the trees, the columns interfere with passage after planting, and are also inferior in appearance to natural standing trees. There are inconveniences such as.

るようにしていた。The T-shaped anchor 20 expands and exhibits a fixing force when it is inserted into the soil. To install the T-shaped anchor 20, first, as shown in FIG. 6, for planting. A small number of small-diameter holes 21 are formed in the bottom of the planting hole 3 accommodating the root pot 2 of the tree 1 by a small scoop or a punching machine (driving auger), and a sleeve 22 is inserted in the small-diameter hole 21. The folded T-shaped anchor 20 is press-fitted using a chisel-shaped rod (not shown), a hammer, etc., and the tip thereof is expanded. Then, as shown in FIG. 7, the belt 2 wound around the trunk
3 and the T-shaped anchor 20 are connected by a wire 25 via a block pulley 24, and the belt 23 is further tensioned by a tensioning device 16 having a ratchet mechanism to support the root pot 2.

傾倒し易いという問題点がある。However, in the above-mentioned planting method, the soil A sandwiched between the T-shaped anchor 20 and the root pot 2 is compressed by the tension of the wire 25. There is a problem that the soil is likely to flow out when rainwater or the like is infiltrated and the shape retention is deteriorated, and in this case, the wire 25 is loosened and the tree is easily tilted.

題点もある。Further, in order to cope with such a situation, it is necessary to perform a maintenance work for regularly tensioning the wire 25 after planting, which increases the economic burden accordingly. Furthermore, there is a problem that the above-mentioned planting method cannot be adopted in a rooftop garden or the like in which the T-shaped anchor 20 cannot be driven at a required depth.

It is an object of the present invention to provide a method for planting trees that can be used for landscaping such as a roof garden while maintaining the above-mentioned atmosphere.

Arranged at the bottom of the hole, after placing the root pot of the tree on the floor plate anchor, the root pot and the floor plate anchor are integrally fixed with a string-like member, and means for embedding this in the planting hole Was adopted.

る。The tree planting method according to the present invention is relatively easy in that the root pot is placed on the floor plate anchor arranged at the bottom of the planting hole, and these are fixed with a string-like member and embedded. Since it can be planted by various works, and the stabilizer of the buried floor plate anchor is locked to a wide range of soil around the root pot, the adhesion force in the soil of the root pot is significantly improved. Since such a floor plate-like anchor sufficiently exhibits the above-mentioned action even in relatively shallow soil, and is fixed directly to the bottom of the root pot without interposing the soil, the cord-like member relaxes. Never. In addition, since the floor-board anchor substantially increases the bottom area of the root pot, the anchor is highly stable even when the soil below the root pot is unevenly settled, and prevents tree tilt.

When burying in the planting hole 3, first, a rectangular stabilizer 4 protruding radially outward from the outer periphery of the bottom pot 2 bottom surface 2a.
The floor plate-shaped anchor 5 with a mark is placed at the bottom of the planting hole 3 (see FIG. 1), and the root pot 2 is placed on this, and then the root pot 2 and the floor plate-shaped anchor 5 are connected by the string-shaped member 6. It is a planting method in which they are integrally fastened and fixed (see FIG. 2), and these are embedded in the planting hole 3 with the soil A (see FIG. 3).

The plate 7 and the rectangular stabilizing plate 4 are fixed by screws. As shown in FIG. 3, both side edges 4a of the stabilizer 4 along the longitudinal direction are bent with a constant width to improve the pressure resistance deformability. In addition, a mountain-shaped hook 11 is fixedly provided on the upper surface of each stabilizer 4, and one end of a cord-shaped member 6 such as a belt or a wire that locks the root pot 2 is inserted into the hook 11 and fastened with a buckle 12. I'm wearing it. The dimensions of the stabilizer 4 and the frame 8 are such that the tree after transplantation is stable in an upright state in consideration of the weight and height of the planted tree 1, the diameter of the root pot 2, the degree of branching, and the like. Is set by an experimental method. For example, in FIG. 1, the average used root pot diameter outer circumference 13 and the practical maximum root pot diameter outer circumference 14 are shown by chain lines.

る。When the floor-board anchor 5 is laid on the bottom of the planting hole 3, the other end of the string-like member 6 is put out on the ground outside the hole in advance, and then the planting tree 1 Is lifted by a hoist (not shown), and the root pot 2 is attached to the floor plate anchor 5
Place on top. At this time, if a small amount of the soil A is filled in the gap between the root pot 2 and the bottom portion 3a, the posture of the tree becomes stable.

The cord-shaped member 6a is arranged in an annular shape around the trunk, and a tensioning tool 16 having a ratchet mechanism is interposed at a connecting portion between both ends so that the ring diameter can be adjusted.

【００１６】そして、図３に示すように、各紐状部材

である。According to the above-mentioned method, even if the bottom shape of the root pot 2 is unstable, the fixed floor board-like anchor 5 stabilizes the posture of the tree, and the bottom area of the root pot 2 is substantially increased. Therefore, it is difficult to sink even on soft ground, and even if the soil A flows out, the fixed state between the root pot 2 and the floor plate-shaped anchor 5 does not change, so it is hard to tilt. It is also a preferable method for protecting and growing trees since it can be used even on hard ground where it is difficult to fix a conventional anchorage and can be stably supported without binding the trunk.

An annular cord-shaped member that surrounds the trunk may be omitted by crossing over the diagonal lines.

点もある。[Effect] As described above, the present invention is a planting method in which the floor plate-like anchor that significantly improves the soil adhesion strength is directly fixed to the root pot bottom of the tree to be planted to maintain the posture of the tree. Therefore, the support of the tree is not exposed to the ground and does not impair the atmosphere of the natural standing tree, and the tree is stable even in soil with soft and low holding power or hard soil that is difficult to excavate deeper than the soil. Since it can be supported, it is also suitable as a planting method for landscaping such as a rooftop garden. In addition, there is no need for maintenance such as tightening the wires after planting, which has the advantage of excellent labor economy.
