Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a convenient cultivation aid that can be used mainly when planting young plants when cultivating plants in orchards, gardens, streets, etc. It is related to the device.

[Conventional technology]

One cultivation technique that has traditionally been widely used in the field of plant production is to repeatedly transplant the plant during its growth process and cut its taproot and thick roots short; This is done with the expectation of sufficient emergence and development of lateral roots and fine roots from the root part. In this way, plants with fully developed lateral roots and fine roots have a higher survival rate at the time of planting (planting, etc.), and also have various effects such as shortening the time required for flowering and fruiting, and improving the shape of the tree. It is well known that this yields properties suitable for intensive cultivation. However, recently planted plants that have not yet taken root tend to fall over due to strong winds, and in order to reduce this damage, supports have become necessary.

[Problem that the invention seeks to solve]

The present invention was made in view of the above-mentioned problems, and
In fact, it is possible to apply it to the underground parts of the plant at the time of planting, etc. without cutting off the tap root and thick root of the plant, and then to expect sufficient tap root and thick root cutting-like effects that are unique to the present invention. The present invention aims to provide a cultivation auxiliary device which not only has the function of preventing lodging, but also supports plants that have recently been planted and have not yet taken root by supporting them above ground. The present invention is a technology related to inventions such as Patent Application No. 111712 filed in 1982 by the same inventor as the present application.

[Means for solving problems]

The cultivation auxiliary device of the present invention will be described in detail below using examples shown in the drawings. That is, the cultivation auxiliary device of the present invention has a plurality of ligature holes (2) on the upper surface of a root system control plate (1) having a flat plate shape or a curved plate shape (for example, a shallow pot shape, a cap shape, etc.), as necessary. crossbar (8) at the top.
) can be attached using bolts or the like, and one or more supports (7) are provided that protrude generally upward, and one or more legs (9) are attached to the root system control plate (1) as necessary. ) is characterized by protruding downward or approximately horizontally. And root system control board part (1)
The pillars (7), which are the most characteristic of the present invention, are installed at several locations on the upper surface of the root system control board (1) on the same or different concentric circles centered on the center of the root system control board (1). By using the strut mounting part (3) which has a strut mounting hole (4) in the central part, they can be assembled removably by engaging, fitting, screwing, etc. These may also be integrally molded. And if we talk about the root system control plate part (1) and the legs (9), these also often have leg attachment holes (6) in the center part of the outer periphery of the root system control plate part (1). By using the leg attachment parts (5), they can be assembled detachably from each other by means of engagement, fitting, screwing, etc., but in rare cases, these may be integrally molded.

Alternatively, the support (7) and the leg (9) are integrally molded, and this is because the support installation holes (10) are provided in the root system control plate (1) from the upper surface to the lower surface. They are assembled so that they can be attached to and detached from each other by means of engagement, fitting, etc.

If we talk about the ligation holes (2), which are characteristic of the present invention and are provided in large numbers through the root system control plate (1) from the upper surface to the lower surface via the guiding surface (14), their general planar shape is as follows. They may be circular, oval or polygonal, and according to their cross-section, they are often provided with a guide slope (13) cut from one or both sides, and the ligated edge (11) is generally wedge-shaped. and ligate the small hole (2) if necessary.
A material constituting the ligature edge (11) for correcting the cross-sectional shape of the root to the planar shape of the ligature edge (11) while ligating the ligature along the inside of the ligature edge (11) forming the ligature edge (11). A ligation assisting part (12), which is generally annular in most cases and is made of a material with a higher degree of flexibility than the hardness of the material, is attached by fitting or welding.

Regarding the materials constituting each part of the cultivation auxiliary device of the present invention, the root system control plate section with a large number of ligature holes is made of ceramics, metal, plastics, or a composite thereof, which can at least destroy enlarged roots in the ligature holes. Anything that can withstand force is fine, and
The rod-shaped support, which is most characteristic of the present invention and has one end fixed to the support attachment part provided on the upper surface of the root system control board, is a crossbar that is resistant to rot near the ground and is attached to the upper end as necessary. In combination with this, any material can be used as long as it has enough strength to prevent the fixed plant from lodging, and plastics, ceramics, or composites thereof are generally used. Further, the legs whose one end is fixed to the leg attachment portion provided on the side surface of the root system control plate may be made of any material as long as it has the desired strength, and are generally made of ceramics, plastics, or a composite thereof.

In addition, if we talk about the ligation auxiliary part that is provided along the inside of the ligation edge and is made of a material with a higher degree of flexibility than the ligation aid part, hard plastic is often used for this part.

[Effect]

To use the cultivation auxiliary device of the present invention, the shape, size (length of the support, etc.), diameter of the ligature hole, burial depth, etc. must be determined in consideration of the target tree species and cultivation conditions, etc., and the root system must be controlled. Cultivation can be achieved by burying the board almost horizontally in a pot of soil, and by using supports extending from the board and protruding above the ground to secure the above-ground parts of the plants planted here.

That is, a pot of soil at the location where the plant is to be planted is dug to a desired depth, a root system control board is installed at the bottom of the hole almost horizontally, often using legs, and the top of the root system control board is Insert and fix one end of a separately prepared rod-shaped support into the support attachment part provided on the same or different concentric circles centered on the center of If necessary, the above-ground part of the plant is fixed there using a crossbar attached to its upper end for cultivation. According to the cultivation auxiliary device of the present invention, the main root that extends almost vertically below the plant root and the thick root that does not form a large angle with the main root can be successfully introduced into the ligation hole by the action of the guiding surface and the guiding slope. be.

The tap root that enlarges over time in the ligated hole and the thick root that does not form a large angle with the tap root are relatively tightened at the ligated edge of the ligated nodule, and the nutrients in the plant body in this area are tightened. The migration of moisture, etc. will be significantly inhibited, and as a result, the development of the main root and the thick roots that do not form a large angle with it below the ligation will be suppressed.
At the same time, the development of the main root and the thick roots that do not form a large angle with the main root above the ligation is promoted, and branch roots and fine roots are evenly generated from this point. The degree of dependence on the roots below the ligature gradually decreases, and gradually shifts to branch roots and fine roots that originate from the main root and thick roots above this ligation, as if they do not form a large angle with the main root. You can get the effect as if you were cutting down a thick root.

〔Example〕

Embodiment 1 There are four pillar mounting parts in the middle of the upper (convex) or lower (concave) surface, each having a pillar mounting hole in the center.
In addition, a root system control board in the shape of a cap with numerous small ligature holes connected to ear-shaped leg attachment parts with leg attachment holes in the center is used at four locations on the outer periphery, and this is used for plant cultivation. Dig the culture soil at the planned location to the desired depth, place the pole attachment part at the bottom of the hole with the support facing upward, and secure it completely by driving a headed leg into each of the leg attachment parts. Furthermore, one end of a rod-shaped support was inserted into each of the above-mentioned support post attachment portions provided on the upper surface of the root system control plate, thereby forming two pairs of support supports that protruded to the ground level on the upper surface of the root system control plate.

After that, some of the soil that had been dug up was backfilled, and a young plant such as a plane tree was placed in the center of these four pillars, and then the entire amount was backfilled and the planting was completed. The above-ground part of this plant was fixed to a crosspiece attached to the upper end of the support using bolts. This cultivation method not only completely prevents young plants that have just been planted but have not yet taken root from lodging due to strong winds, etc., but also allows the taproot to grow almost vertically downward in the ground. The thick root, which does not form a large angle, is guided into the ligation hole and ligated, and many branches and roots are generated almost horizontally from all parts of the root above the ligation, resulting in an imbalance between vegetative and reproductive growth. It is possible to obtain the harvested plant body.

In addition, if a ligation auxiliary part is attached along the inside of the ligation hole, fine roots, etc., can be ideally extended from all parts evenly in a nearly horizontal direction beyond the ligation part of the root of the plant. I was able to get the status.

〔Effect of the invention〕

The cultivation auxiliary device of the present invention is often used in anticipation of the unique taproot that appears after a relatively long period of time and the effect of pruning a large root that extends without forming a large angle with the taproot. According to the cultivation auxiliary device of the present invention, it is installed integrally or removably with the root system control board buried in the ground, the upper half of which is exposed above the ground, and a crossbar is attached to the upper part as necessary. Not only can recently planted plants that have not yet taken root be fixed using these supports, allowing them to be cultivated with confidence without worrying about lodging, but the underground parts of the plants can also be grown safely. The thick root, which extends almost vertically downward, is introduced into the ligation hole and is relatively ligated, and vegetative growth is achieved by promoting the development of lateral roots, which grow from the roots above the ligation, and which extend approximately horizontally. Plants with well-balanced reproductive and growth can be obtained quite naturally without resorting to highly sophisticated pruning techniques.

In other words, plants grown using the cultivation auxiliary device of the present invention have various effects such as a higher survival rate during planting (planting, etc.), a shorter time required for flowering and fruiting, and a better tree appearance. It exhibits properties suitable for intensive cultivation. In addition, since the cultivation auxiliary device of the present invention has a support, when it is applied to roadside trees that are poor underground due to lack of sunlight in areas with high-rise buildings, it creates a so-called building-like effect.
It is possible to prevent damage from falling trees in the event of strong winds such as typhoons, and there will be no obstruction to traffic caused by fallen trees. According to the cultivation auxiliary device of the present invention, there is no need to use expensive and easily rotten wood logs as supports, and if a standard is created, it is versatile and economical.
