Description

[Detailed description of the invention] The present invention relates to a root system control device.

Traditionally, in the cultivation of street trees, garden trees, fruit trees, etc., the main purpose of trimming the trees is to improve their appearance and to promote flowering and fruiting. Unless it was done at the same time, good results could not be expected, and it also required a great deal of effort.

This was even more true, for example, for trees that were young and had only vigorous vegetative growth.

The present invention was made in view of the above-mentioned problems, and takes advantage of the geotropism of the roots of plants, and when planting seedlings, etc., it is used directly under them, and after a certain period of time, it continuously acts on the roots. It exhibits a unique effect; it balances vegetative growth and reproductive growth, suppresses the emergence and elongation of overgrown branches in the above-ground area, improves the appearance of the tree, and promotes flowering and fruiting. The object of the present invention is to provide a completely new plant cultivation article that allows the formation of a sufficient and healthy root group underground.

The root system control device of the present invention will be described in detail below with reference to an embodiment shown in the drawings. That is, the ligature plate mounting hole (6) is provided in the center, and the guiding part (4) surrounding this is provided with a large number of ligature plates (5), and has a generally circular shape or a cap shape with a chipped center part. A ligation plate (1) having a generally disc-shaped or shallow bowl-like shape and having a large number of ligation holes (2) is fitted into the ligation plate mounting hole (6) of the ligature guide plate (3). This is a root system control device consisting of a fixed pile attachment part (7) provided with a fixed pile insertion hole (8) at the periphery of the guide plate (3) as required.

Regarding the ligation holes (2) that are provided in large numbers through the ligation plate (1) from the upper surface to the lower surface, their general planar shape is circular, elliptical, or polygonal (including, of course, star shapes, etc.). According to their cross-sections, they often have a shape cut from one or both sides, which serves as a guiding slope, and the ligated edges are often wedge-shaped. . In addition, if we talk about the many ligature holes (5) that penetrate through the guide plate (3) from the upper surface to the lower surface, their general planar shape is generally isosceles triangular, oval, elliptical, etc. in most cases. They are generally long and slender and arranged so that their long axis (or the center line of the longer one) is located radially with respect to the center of the guide plate (3), and their cross section is According to the authors, they are often provided with a guide slope (9) cut from one or both sides, and the ligature edge (10) is often wedge-shaped.

Ligation plates (1) each shaped like a disk or bowl, each individually designed to produce its own unique effect.
The guide plate (3), which is approximately annular or has a cap shape with a chipped center, is used when the outer periphery of the ligation plate (1) and the inside of the ligation plate mounting hole (6) of the guide plate (3) are connected. They are assembled together by means such as fitting around their peripheral edges or tightening bolts and nuts, but in some cases these are integrally molded from the beginning of manufacture.

Ceramics (including products using cement) are generally selected as materials for forming the ligation plate (1), guide plate (3), stakes, etc. that constitute the root system control device of the present invention, but other materials are also used. To achieve the desired purpose by being physically and chemically stable and able to overcome the destructive force of the main root that enlarges in the ligation hole (2) and the ligation hole (5) or the large root that extends without forming a large angle with the main root. Any material that can be used may be used, including plastics, metals, and composites thereof.

The root system control device of the present invention is used with the expectation that it will produce a unique effect after a relatively long period of time. The shape and size of the ligation hole (2) and the ligation hole (5), the burial depth, etc. are determined, and the holes are buried almost horizontally in the soil.
Seedlings are planted and cultivated on top. That is, the soil in the area where seedlings, etc. are planned to be planted is dug to a desired depth, and an appropriately selected guide plate (3) is first placed almost horizontally at the bottom of the hole, and soil is sufficiently backfilled inside and outside of the guide plate (3). Later, a suitably selected ligature plate (1) is attached, and then the soil is further filled in, and the seedlings are placed on top of the ligature plate (1) to complete the planting.

According to the root system control device of the present invention, a large number of tap roots that extend almost perpendicularly below the roots of the plant body and thick roots that do not form a large angle with the tap roots are successfully attached to the ligation plate (1) by the action of the guiding slope, etc. The tap root is introduced into the ligature hole (2), and the tap root that enlarges over time in the ligature hole (2) and the thick root that does not form a large angle with the tap root are introduced into the ligature hole (2).
The ligated edge of the ligated hole (2) is relatively constricted, and the transfer of nutrients and water in the plant body in this area is significantly inhibited, and as a result, the main root and its large angle are The development of the main root that does not form below the ligature is suppressed, and at the same time, the development of the main root and the large root that does not form a large angle with it above the ligature is promoted, and branch roots and roots from this are promoted.
This results in the uniform development of fine roots, and the degree of dependence on the roots below the ligation in the above-ground part of the plant gradually decreases, and gradually the dependence on the roots above the ligation and the thick roots that do not form a large angle with the main roots above the ligature gradually decreases. This results in a transition to more developed branches and roots, creating an effect as if the main root and a thick root that does not form a large angle with it were cut down. On the other hand, due to the action of the lateral roots that extend at a certain angle with the main root and the above-mentioned ligation plate, the guide plate (3) still hits the guide plate (3) and guides the branch roots that have arisen and extended from the main root and the thick roots that do not form a large angle with the main root. Some of the guided roots descend along the surface (4), but due to the action of the guiding slope (9), etc., they are successfully inserted into the ligation holes (5) made in large numbers on the guiding plate (3). The guided root, which enlarges over time in the ligation hole (5), is introduced into the ligation hole (5).
) is relatively constricted by the ligated edge (10), and the transfer of nutrients, moisture, etc. in the plant body in this area is significantly inhibited, and as a result, the area below the ligated part of the guided root is The development is suppressed, and at the same time, the development of the guided root beyond the ligated part is promoted, especially branch roots that form a larger angle with the main root that develops from the outside (meaning the side far from the center of the guide plate). This results in vigorous growth. Here, in many cases, the ligature holes (5), which are formed in large numbers in the guide plate, are approximately in the shape of an isosceles triangle or an ellipse, or are slightly elongated, and their long axes are located at the center of the guide plate (3). By doing so, it is possible to reliably capture guided roots, etc. that enter at a certain angle with respect to the ligation hole (5). Furthermore, by adopting this configuration, branches and roots are more likely to develop outward from the upper part of the ligation.

Embodiment A ligation plate device having a guide plate (3) that opens downward and has a large number of oval ligation holes (5) arranged in a radial manner, has a cap shape with a chipped center part, and has a stake attachment mechanism on its periphery. In the hole (6),
When plants were cultivated using a root system control device consisting of mutually attached shallow pot-shaped ligation plates (1) that open upward and have a large number of regular polygonal ligation holes (2), the plant was grown almost downward. The elongated taproot or the thick root that does not form a large angle with the taproot was ligated through the ligation hole (2) of the ligation plate (1), and lateral roots were often generated above the ligation, and the root that formed a certain angle with the taproot. Due to the action of the lateral roots and the above-mentioned ligation plate (1), the branch roots, etc. that have arisen and grown from the main root and the thick roots that do not form a large angle with the main root, still hit the guide plate (3) and the guide surface (4) Although there are guided roots that descend along the guide plate (3), most of them are also ligated by the ligation hole (5) of the guide plate (3), and more branch roots are generated from the outside than the ligation. It is. In plants cultivated using the root system control device of the present invention, the proportion of roots extending almost horizontally was higher than that in the natural state, the tree appearance was regular, and flowering and results were more vigorous. Furthermore, it was used on tree species that are prone to lodging and successfully prevented lodging due to strong winds.

A major feature of the root system control device of the present invention is that the ligation plate and guide plate, each having a unique configuration and capable of producing unique effects, can be combined or integrated with each other. A healthy plant in which a sufficient rhizosphere is formed above the ligation by the root system control device of the present invention has a remarkable fertilizing effect, and exhibits properties suitable for fertilizer management, and indeed for intensive cultivation. far exceeds what was obtained by conventional branch techniques. In other words, in a plant that has fully developed fine roots as described above using the root system control device of the present invention, the balance between vegetative growth and reproductive growth is maintained, and the time required for flowering and fruiting is not only shortened. The yield has increased, and the tree is in good shape, giving the appearance of an older tree.

In addition, when fixed stakes are used with the root system control device of the present invention, it is very stable and can be used for tree species that are prone to lodging, street trees, garden trees, etc.
It is applied to fruit trees, etc., and can withstand strong winds such as typhoons.

In addition, when using fixed stakes in orchards on slopes, there is a track record of successfully preventing fruit trees from being washed away by floods.
