Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cultivation aid used for cultivating plants.

One of the cultivation techniques that has been widely used in the field of plant production is to cut the taproot short during the growing process of the plant, but this does not allow sufficient development of lateral roots from the remaining taproot. It is something that is expected. Plants that have developed lateral roots in this way have various effects such as a higher survival rate when replanted, a shorter time required for flowering and fruiting, and a more uniform tree shape, making them suitable for intensive cultivation. It is well known that this phenomenon can lead to certain characteristics. However, in order to cut down the taproot, the plant must be dug up or brought into a similar state, and the reality is that growers have been forced to perform extremely hard labor due to the work involved.

The present invention has been made in view of the above-mentioned problems, and is actually used at the time of sowing or planting seedlings without cutting down the taproot, and thereafter achieves a sufficient taproot truncation-like effect unique to the present invention. The aim is to provide a new cultivation aid that can be obtained.

The cultivation aid of the present invention will be described in detail below using examples shown in the drawings.

That is, the cultivation aid of the present invention has a circular plate (1) having a generally concave lens shape in cross section, which has a uniform thickness or gradually becomes thinner from the periphery toward the center. A single tap root ligation hole (2) having a wedge-shaped cross section is bored. Then, if necessary, radial cuts (4) are made in the holes (2) made in the center of the plate.
), etc., is attached by means such as pasting. Here, the general shape of the plate (1) is not limited to a circular shape, but may be any polygonal shape, and the shape of the root ligation hole (2) is not limited to a circular shape, but may be an ellipse or a polygonal shape. In the latter case, effects depending on the shape can be expected, as will be described later.

Generally, ceramics are selected as the material for forming the cultivation aid of the present invention, but any other material can be used as long as it can withstand the destructive force that accompanies the enlargement of the taproot, including plastics, metal, wood, etc. For its production, ordinary methods such as molding and cutting are used. In addition, the plant support piece (3), which has radial cuts (4), etc., and is fixed by pasting into the hole (2) provided in the plate is often made of a thin plastic plate. Therefore, if the material of the plate (1) is plastic, it is usually integrally molded.

It is very easy to use the cultivation aid of the present invention, and when planting the young plant (5), the tap root (6) is usually attached to the center of the board (1). All you have to do is insert the seedlings into the hole (2), which has a diameter much larger than the diameter of hole (6), to about 80% of its length and complete the planting. At this time, if a device with a plant support piece (3) in the hole (2) is used, the main root (6) of the plant (5) can be held between the plant support piece (3) within the cultivation aid. Since it is fixed in place, the work can be done more easily and reliably. Furthermore, when using the cultivation aid of the present invention at the time of sowing, it is sufficient to arrange the cultivation aid in the seeding field with the recess facing up, sow the seeds on the recess, and cover with soil, and the seeds will not root. The roots descend along the concave wall and grow into the hole (2), and depending on the size of the hole in the cultivation aid used, they can be applied to the young plant after one to several years. It is possible to obtain the same taproot pruning effect that is unique to the cultivation aid of the present invention.

The vertical relationship between the surfaces of the cultivation aid of the present invention is not specified, and the user can decide which surface should be the top (bottom) by taking into consideration the surrounding circumstances, and the cultivation aid It has become common for the size of the device to be portable.

The taproot pruning-like effect unique to the cultivation aid of the present invention means that the growth of the taproot below the cultivation aid is suppressed by ligating the taproot using the cultivation aid without actually cutting the taproot. (without causing it to wither), and above this cultivation aid, it can only be obtained by reasonably promoting the generation and growth of lateral roots from there (the conventional method of digging up and cutting down the tap root) In this case, the plant body was subjected to a large shock, and it was not possible to generate sufficient lateral roots at the cut site to generate a secondary taproot). In other words, if the cultivation aid of the present invention is used, the main root, which enlarges over time, will be relatively tightened by the wedge-shaped part formed around the hole (2) drilled in the center of the main root. The passage of nutrients, moisture, etc. in the plant body is inhibited, and as a result, the growth of the main root below the cultivation aid is suppressed, and at the same time, the growth of water above the cultivation aid is promoted. As a result, the dependence of the above-ground parts of the plant on the underground taproot gradually decreases and the plant gradually shifts to the lateral roots, as if the taproot had been cut down. You can get the effect. The cultivation aid of the present invention is used with the expectation of a unique taproot pruning-like effect that appears after a relatively long period of time.
) Depending on the shape of the hole (2), the effect will be slow or slow.
When the shape of hole (2) is an ellipse or a polygon other than a circle, the root enlarges while leaving a gap at the corner of the hole, and the taproot truncation-like effect due to taproot ligation is compared to that when the hole (2) is circular. It appears more slowly.

By using the cultivation aid of the present invention, the grower can avoid heavy labor without damaging the plant and weakening it, unlike the conventional method of digging up the plant and cutting the taproot. This prevents the generation of coarse roots from the vicinity of the cut, which is often seen in this case, and prevents the lateral roots from sprouting evenly from the remaining main root and the growth of fine roots from there. It is possible to obtain plants with extremely good quality, which are far superior to those produced by conventional techniques. Plants that have fully developed lateral roots using the cultivation aid of the present invention have an extremely high survival rate when replanted, and can be used, for example, as rootstocks for grafting immediately after being dug up. The rootstock curing period is necessary), and the balance between vegetative and reproductive growth is achieved, which not only shortens the time required for flowering and fruiting, but also increases yield, and the tree looks as if it has grown old. In addition, the roots are well developed and the fertilizer effect is remarkable, making it suitable for fertilization management and in fact suitable for intensive cultivation, which far exceeds anything obtained using conventional techniques.

In addition, young plants with fully developed lateral roots that are planted using the cultivation aid of the present invention continue to grow vigorously even when they become mature trees. It has been used to great effect in various fields of agriculture and forestry.
