Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag used for growing trees and also used for distribution.

[0002]

2. Description of the Related Art Conventionally, the roots of greenery trees cultivated in a tree cultivation bag spiral downward along the inside of the peripheral wall of the tree cultivation bag without splitting only a few side roots and main roots. As a result, a so-called looping phenomenon occurs, in which the inside of the plant has poor rooting and a hollow state, which has a decisive effect on the growth of transplanted trees, especially after transplanting. There is a problem that it is easily affected by winds such as a typhoon or the like and rolls over from the root.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a tree cultivation bag capable of preventing a root looping phenomenon and forming a strong root form. The gist of the present invention is to form a bottomed bag with a water-permeable nonwoven fabric having a bottom inclined portion whose diameter is reduced in a conical shape downward from the lower end of the cylindrical side wall portion, and at least the aforementioned A guide ridge for guiding water and roots downward is provided vertically inside the side wall.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective configuration view of a tree cultivation bag 1 according to a first embodiment. The cultivation bag 1 is entirely formed of a nonwoven fabric having water permeability and air permeability, and has a hexagonal shape whose upper end is open. On the lower end side of the cylindrical side wall portion 2, a bottom inclined portion 3 which continuously reaches a bottom central vertex portion 4 is formed, and the bottom inclined portion 3 has a conical shape and a lower vertex portion 4 is formed. The tree cultivation bag 1 is formed in a bottomed bag shape having an open upper end as a whole.

Also, six guide ridges 5, 5, 5, 5 are formed at predetermined intervals from the side wall portion 2 to the bottom inclined portion 3, respectively, and each guide ridge 5 is directed inward. In the present example, the guide protrusions 5, 5, 5 are formed at the corners of each hexagon, and the lower end of each guide protrusion 5 is formed at the apex 4. It has been focused on. Each of the guide ridges 5 is formed by integrally sewing the inside of the tree cultivation bag 1 to the inside by forming a nonwoven fabric. The soil E is put in the tree cultivation bag 1 thus formed, and the roots of the tree 10 are grown inside as shown in FIG. FIG. 2 illustrates the process of growing the roots of the tree 10.

[0006] In the process of growing the main roots 11 of the vegetation tree (trees) 10 in the soil E put in the tree cultivation bag 1, when watering is performed from above, the water that has been irrigated is mainly due to capillary action. The water penetrates into the inside, but the water passes through the side wall portion 2 and is guided downward by the guiding ridges 5 to flow downward. When the growth point comes into contact with the side wall portion 2, it turns along the peripheral wall of the side wall portion 2, and when the growth point comes into contact with the guiding ridge 5, the growth point hits the guiding ridge 5, thereby causing stress. Therefore, it is guided downward along the guiding ridge 5. Therefore, the several side roots 12, 12, 12 extending outward from the main root 11 are respectively guided along the side walls 2 and then guided downward along the guiding ridges 5.

In this embodiment, as described above, the side wall 2
Inclined part 3 whose diameter is reduced in a conical shape from the lower end of the bottom toward the bottom
The guide ribs 5 are formed of a water-permeable non-woven fabric, and the lower ends of the guide ridges 5 are converged at the apex portions 4, so that stagnant water adhering due to surface tension is reliably drained from the apex portions 4. The growth point at the tip of the lateral roots 12, 12, 12 grows in a good aerobic condition under a condition where a sufficient amount of oxygen is supplied, and a sufficient amount of oxygen is supplied. As a result, the growth point of the lateral root 12 gradually becomes a short cell tissue, and naturally stops growing while maintaining a healthy state. As shown in FIG. 2, a number of roots (towing roots) 13 are rooted and grown from the main root 11, and the rooted roots 13, 13, 13 are:
Since there is the bottom inclined portion 3 whose diameter is reduced in a conical shape downward, the root 13 grows in a converging state with its density increased toward the lower side. The growth of a large number of heart roots 13 increases the number of growth points and increases the growth hormone, thereby promoting the growth of the aerial part of the green tree 10.

In the prior art, the lateral root 12 continues to grow in an anaerobic state due to the influence of the stationary water, and only the water is sucked up so that the cell tissue at the growth point becomes a long cell tissue. In addition, the side roots 12 rotate along the peripheral wall of the side wall portion 2 and continue to grow,
Conventionally, the root is constituted only by the main root 11 and the several side roots 12, and the mechanical strength of the whole root is weak and the nutrient absorption capacity is extremely weak. As described above, the grown roots have high nutrient absorption due to the large number of heart roots 13, and each heart root 13 converges downward, forming a collective root having a large mechanical strength in a wedge shape as a whole. It will be.

The roots in which a large number of heart roots 13, 13, 13 are bundled in this way have a high mechanical strength when the tree cultivation bag 1 is removed and transplanted, so that the transplanting operation can be performed easily. It will be. In addition, the upper part is formed in a shape with a large area, so it can be prevented from falling down in the transplanted state, it is firmly transplanted and does not fall down due to the influence of wind etc. It will be easy.
In addition, since the root has a large number of heart roots 13, 13, 13, it is possible to favorably absorb nutrients from the ground and promote the growth of the above-ground parts, causing an aging phenomenon as early as in the past. There is no such thing as.

FIG. 3 shows a second embodiment. In FIG. 3, the tree cultivation bag 1 is formed in a square-shaped bottomed bag. From the lower end of the side wall portion 2 formed in the shape of a cone, a bottom inclined portion 3 is formed by tapering downward in a cone shape, and each corner portion is formed vertically from the inside of the side wall portion 2 toward the bottom inclined portion 3. Guiding ridges 5, 5, 5, 5 are formed so as to protrude inward, so that the guiding ridges 5 can satisfactorily guide water and roots downward.

Although the tree cultivation bag 1 is exemplified by a hexagonal shape and a square shape, the tree cultivation bag 1 may be circular, octagonal or pentagonal. In this case as well, the guide ridge 5 is formed to protrude inward so as to be formed in the vertical direction, so that water and roots can be guided well downward.

[0012]

The tree cultivation bag of the present invention has a bottom inclined portion having a bottom inclined portion whose diameter is reduced in a conical shape downward from the lower end of the cylindrical side wall portion. In addition, at least on the inner side of the side wall portion, a guiding ridge for guiding water and roots downward is provided vertically,
The water irrigated in the tree-cultivation bag flows down along the guiding ridge, and flows downward from the center of the bottom slope, leaving no residual water due to surface tension around the bottom slope. A good drainage function is provided, which provides sufficient oxygen to the roots, and the roots of the roots become cellular tissues whose growth point is short due to sufficient oxygen, which naturally grows on the side wall or bottom slope. The roots stop, which causes many heart roots to grow from the roots of the roots, and the roots do not cause looping as in the past. Along with promoting, the heart root becomes firmly focused to the bottom side along the bottom inclined part which is reduced in cone shape, removing the tree cultivation bag, easy to transplant when transplanting trees, due to the influence of wind etc. Without falling down, An effect that can be top of the growth to grow good trees.
