Description

How to plant seedling raising tools, planting mobiles and long root seedlings

The present invention relates to a seedling raising tool used for greening long root seedlings in arid land, degraded land, etc., a planting moving body, and a method for planting long root seedlings.

In the greening of dry land and degraded land, planting long root seedlings with a long root system that can reach a stable soil layer with a stable temperature and moisture below a certain depth (approximately 50 cm) throughout the year in order to improve the survival rate and survival rate of the planted seedlings. Is valid. Since this technology can directly form a root system deep underground at an early stage, it may be applicable to disaster prevention forests or coastal forests. However, since long root seedlings have a long root system, it is difficult to remove them from the seedling raising tool, and they are easily damaged during operations such as demolding, transportation, and planting, and plug seedlings are heavy and workability is reduced.

Drilling a deep hole for planting long root seedlings requires digging a large-diameter hole due to the collapse of the hole wall, which requires excavation and backfilling of a large amount of soil, which reduces workability. Irrigation and rainwater permeate a large amount of backfill soil and stay near the surface. Long-rooted seedlings that have developed a root system near the surface due to the water tropism of the roots have a reduced survival rate due to high temperature and water stress near the surface in the dry season. In order to extend the long root seedlings further downward, a planting hole excavation technique is required in which the hole wall does not collapse and rainwater penetrates vertically.

In this way, the invention of the present application was derived from the idea that integrated technology of each process such as raising seedlings, excavating planting holes, and planting is required for greening dry land with long root seedlings.

Patent Document 1 discloses a working machine for the purpose of blocking the outflow of soil moisture and insulating geothermal heat for greening areas such as deserts. In this work machine, the outer cylinder and outer sack are pushed into the ground in conjunction with excavation with a hollow auger that can open and close the opening at the tip, and the inner sack with planted seedlings is thrown into the hollow auger and the opening is pushed open to land on the floor. , Embed inside and outside sack.

Patent Document 2 discloses a nursery block in which a half-split hollow cylindrical block having a diameter of 5 to 20 cm and a height of 5 to 20 cm is united. This block is made by pressure molding with soil-based materials, and it is said that seedlings are stored inside and buried in the ground at the time of planting, and after 6 to 20 months, they naturally deteriorate and collapse due to root system growth.

Patent Document 3 discloses a short-term growing tool for a dry place or the like, which is composed of a half-split tubular body and a plate-shaped lid material. Low-hardness cultivation soil squirrel Using this tool, seedlings are raised at an angle of 30 to 70 degrees and embedded in a boring hole in a planted area. A porous material having water permeability, water retention, and breathability is used for the cylinder. It is said that it is preferable to embed a biodegradable material because the collection of the lid material and the cylindrical body becomes complicated in the process.

Planting with the work machine described in Patent Document 1 requires many tools and work processes.

The childcare block described in Patent Document 2 has low rigidity, so it has a low profile, a low aspect ratio, and a thick wall surface. Heavy containers reduce planting workability, and short root raising seedlings in low-profile containers require a large amount of continuous irrigation, including horizontal penetration, until they extend to a stable soil layer.

The structure that covers the half-split cylinder described in Patent Document 3 is highly airtight, and the continuous porous cylinder for ensuring breathability is difficult to manufacture and is inferior in mechanical strength and durability.

The division is made in a plane
It is a seedling raising tool characterized by comprising a divided collective pipe in which the divided surfaces of the two divided pipes face each other.

Hereinafter, description will be given with reference to the drawings.
FIG. 1 (1) shows the split pipe 1. A cylindrical pipe with both ends open having a length of 50 cm or more and an inner diameter aspect ratio of 5 or more is divided or cut in two by a dividing line 2 in the longitudinal direction.
FIGS. 1 (1) and 1 (a1) show the split pipe 1 produced by the molding method. The split pipe 1 is a semi-cylindrical pipe, and the arc center 3 exists on the line connecting both split lines 2.
FIG. 1(1)(a2) shows a split pipe 1 made by cutting a cylindrical pipe with a blade. In the split pipe 1, the thick portion of the blade is cut from the semi-cylindrical pipe, and the arc center 3 exists outside the line connecting the two split lines 2.
Either split pipe can be used.

1 (1), (b1), and (b2) show the split pipe 1 as viewed from the inside of the cross section.
The dividing line 2 is shown as a dividing surface 2 formed of a two-dimensional plane in this figure because of the thickness of the dividing pipe.
As for the thickness of the divided pipe, a commercially available vinyl chloride pipe can be used in the case of a synthetic resin pipe, the VP pipe having an inner diameter of 77 mm has a wall thickness of 5.5 mm, and the VP pipe having an inner diameter of 51 mm has a wall thickness of 4.1 mm.

FIG. 1 (2) shows a divided assembly pipe 5 in which the divided surfaces of the divided pipe 1 are opposed to each other.
1 (2), (a1), and (b1) are divided assembly pipes 5 in which the molding method divided pipes are opposed to each other.
FIG. 1(2)(a2) shows a divided collective pipe 5 in which the cutting method divided pipes are opposed to each other.
FIG. 1(2)(a3) shows a case where a cylinder is cut obliquely in the long axis direction.
Any split set pipe can be used.
The unevenness of the divided surface due to molding and cutting at the time of making the divided pipe, damage at the time of use, etc. does not impair the two-dimensional flatness.

FIG. 2 shows a perspective view of a method of raising long-rooted seedlings using the seedling raising tool 5. The seedling raising tool 5 is stored substantially vertically with its outer circumference restrained by the seedling raising rack 13, and the bottom surface is stretched between a plurality of pedestals 15. It is supported by the passed mesh 14 to prevent the soil from falling off.
The seedling raising tool 5 is filled with soil and seeding or seedlings (including cuttings and rhizomes) are transplanted, and fertilization or irrigation is performed at appropriate times to raise long-root seedlings.
(Hereinafter, the root system and the components of the soil in the container are "root pots" 12, the long root seedlings with root pots raised with the seedling raising tool 5 are "plug seedlings" 11, and the seedling raising tools with plug seedlings are ("plug seedling raising tools". "10.)

During seedling raising, the volume of the root pot 12 is increased by irrigation and the growth of the root system, the divided surface between the two divided surfaces 2 is expanded, and the air permeability is improved. As a result, in the dividing line 2, the plug seedling 11 having a straight root without the root wrapping effect can be grown like the slit of a commercially available slit-containing seedling growing container.
In the root pot 12, it is preferable to extend the root system to the mesh 14, which prevents root wrapping due to the air root cutting effect of the mesh 14 and prevents the soil from the plug seedling raising tool 10 taken out from the seedling raising rack 13 and transported to the planting site. It will be possible.

For planting, the plug seedling raising tool 10 is positioned or inserted above the planting hole, and the plug seedling 11 stored by giving an impact such as hitting the upper part of the plug seedling raising tool 10 with a hammer is removed from the lower end of the seedling raising tool 5 ( Hereinafter, it is referred to as "lower end demolding"), it is dropped into the planting hole, or the plug seedling 11 is left in the planting hole and only the seedling raising tool 5 is pulled up.

In the above planting, the root pot 12 is protected by the seedling raising tool 5 even during transportation, and improvement in survival rate can be expected by drying and preventing damage. Compared with the non-cylindrical pipe seedling raising tool, the cylindrical pipe seedling raising tool 5 has a smaller contact interface with the root pot 12 and can be easily demolded at the lower end.
By setting the length of the seedling raising tool 5 to an arbitrary length that can reach the stable soil layer, the planted root pot 12 directly reaches the stable soil layer, and improvement of the survival rate and survival rate can be expected.
By setting the seedling raising tool 5 to have an aspect ratio of 5 or more, workability is improved by reducing the amount and weight of the filling soil.
