Abstract

PROBLEM TO BE SOLVED: To solve problems that there is need to expose the opening in a front sheet because the root system of a young tree is buried in culture soil after closing a filling opening by filling the culture soil in the case of a bag for planting in which front and rear sheets are integrated, it is very difficult to form an opening and do planting work by one man because it is difficult to secure a sufficient opening necessary for planting unless a planting hole opening is widened by both hands in the case of the bag in which a straight line shape planting hole opening is formed.SOLUTION: A planting article has a front sheet (1) and a rear sheet (2). The front sheet is constituted of a water impermeable material and has radial cut lines (12) for providing an opening (11) of an area necessary when planting. The rear sheet is constituted of a nonwoven cloth having water permeability and air permeability has an area smaller than that of the front sheet and root passages (21) are formed in the rear sheet. Further, the rear sheet is affixed to the front sheet excepting parts covering the cut lines and becoming filling opening (22) of the front sheet.

Description

  The present invention relates to a planting product used for planting a planting surface.

Japanese Patent No. 3590715 (Patent Document 1) is known as a sapling production bag used for planting a planting surface. In this bag, each impermeable sheet portion is integrated at the periphery, leaving a filling port for the soil. In use, the medium is filled into the space between the water-impermeable sheets through the filling port. When filling is completed, the filling port is closed. Open one impermeable sheet and embed it into the soil through the root system of the seedling. The bag in which the seedling is planted is placed on the planting surface.
Japanese Patent No. 4456454 (Patent Document 2) discloses an invention in which a straight planting hole opening 8 is provided in the single-sided sheet 1 so as to eliminate the opening of the bag by the blade.

Japanese Patent No. 3590715 Japanese Patent No. 4456454: Paragraph 0035

In the case of the bag of Japanese Patent No. 3590715, after filling the culture medium and closing the filling port, it is necessary to open one impermeable sheet portion in order to embed the root system of the seedling in the culture medium. This work is quite troublesome because if the length of the cut is too short, it interferes with the insertion of the root system of the seedling, and if it is too long, the soil will leak.
In the case of the bag disclosed in Japanese Patent No. 4456454, this planting hole opening 8 expands the middle part to plant a plant, but if this planting hole opening is not expanded with both hands, a sufficient opening necessary for planting should be secured. It is difficult to do both opening and planting work alone.
An object of this invention is to provide the planting article which can reduce the trouble of this cutting and can ensure sufficient planting opening easily.

(Claim 1) The planting article according to the present invention has a front sheet and a back sheet. The front sheet is made of a water-impermeable material and has radial cuts that provide an opening of an area necessary for planting. The back sheet is composed of a non-woven fabric having water permeability and air permeability, has an area smaller than that of the front sheet, and has a root passage. Then, the back sheet is attached to the front sheet so as to cover the cut of the front sheet and leave a portion that becomes a filling port.

  Here, the expressions “front sheet” and “back sheet” are used, but they are relative and simply mean that the two sheets are opposed to each other. The front sheet preferably has a biodegradability, water resistance, corrosion resistance, and strength sufficient to prevent tearing by a pulling force by human power. For example, a three-layer polyethylene is used. The back sheet is a non-woven fabric and, like the front sheet, desirably has biodegradability, water resistance, and corrosion resistance. However, in terms of strength, it is sufficient if it is not broken by the material pressure of the filler. In the following description, the soil that is generally employed as a filler is taken as an example, and the pressure is expressed as soil pressure, but of course it is not limited to soil.

  The cut is generally cut by a mold. A male mold with a cutting edge and a female mold with a groove to store the cutting edge are used. A certain number of sheets are stacked and placed on the female mold. Disconnect. The length of the cut formed by cutting the sheet corresponds to the length of the cutting blade. An opening for planting is provided by inverting the cut to the outside or the inside of the front sheet at the time of planting. The length of the cut is such that even if the culture soil is filled in the space between the front and back sheets, the cut does not leak out due to excessive earth pressure. The radial cut means a state in which three or more cuts extend radially from the center.

  The back sheet is composed of a nonwoven fabric having water permeability and air permeability. The area is smaller than that of the front sheet, and a root passage is formed. The root passage only needs to be able to project through the back sheet to the planting ground when the root system of the plant is growing, and any appropriate means such as slits, cuts, and through holes can be adopted. Then, the back sheet is attached to the front sheet so as to cover the cut of the front sheet and leave a portion that becomes a filling port.

  As a method of attaching the back sheet to the front sheet, an appropriate method such as adhesion, fusion, or sewing can be adopted. A root passage is formed in the back sheet. Although the number may be suitable, it is preferable to scatter a plurality. Moreover, the opening area should just be a grade which a root can penetrate | invade into cultivation soil through this root passage, and cultivation soil does not leak.

  This planting article opens the filling port so as to peel off the front and back sheets of the portion serving as the filling port, and fills the space appearing between the front and back sheets through the filling port. As it is filled, the middle part of the cut of the front sheet is expanded by the earth pressure of the cultivation soil, but the outer edge is regulated, so if it expands to some extent, it will not expand further. Therefore, the soil does not leak to the outside through the expanded part.

  In addition, the back sheet is also subjected to soil pressure by filling soil with soil. Although the opening area of the root passage is small, a part of the soil may leak to the outside through the root passage due to an impact during filling. However, the soil is viscous, and its resistance causes a bridging phenomenon near the root passage, preventing further leakage.

  After filling the culture soil, close the filling port. For this closure, clips, sewing, pinning, bonding or other suitable methods can be employed.

  Place the seedlings on the planting supplies with the filling port closed. If the cut portion is inverted to the outside or the inside of the front sheet, an opening having a sufficient area for planting parallel to the cultivated soil surface appears. Leave the branches and leaves of the prepared seedlings outside the planting supplies, and bury their roots in the cultivation soil through this opening. These tasks can be done by one person.

  The planting material provided with the seedlings thus made is installed with the planting surface facing the planting surface and the back sheet facing the planting surface. The root system of seedlings grows in the planting soil through the root passage of the back sheet.

(Claim 2) The cut may be discontinuous at the concentrated portion.
In this way, even if the maximum volume of soil is filled in the space between the front sheet and the back sheet, the length of the cut is regulated at the concentrated part, so the mouth of the cut will not open more than a certain extent, Prevents soil from leaking.

(Claim 3) The cut may be provided with an incision scheduled portion on an extension of its radial direction.
In this way, since the length of the cut when filling the culture soil does not need to be excessive, there is less risk of the culture soil leaking out, and when the plant to be planted is large, the cut is expanded to the planned incision and the opening is enlarged, Planting can be performed easily.

(Claim 4) The incision part which continues on the extension of at least one of the cuts may be formed in the concentrated portion.
If it carries out like this, at the time of planting of a seedling, this concentrated part can be easily fractured | ruptured by this incision scheduled part, and a wide opening can be ensured.

(Claim 5) The concentrated portion may have a strength capable of withstanding the pressure of the maximum volume of soil filled in the space that appears between the front sheet and the back sheet.
In this way, even if the earth pressure at the time of filling the soil is large, the concentrated portion receives this, so that the cuts are not expanded at the same time and soil leakage does not occur.

(Claim 6) The opening area of the root passage may be a size that prevents leakage of the soil filled in the space that appears between the front sheet and the back sheet.
In this way, the root passage can prevent the soil from flowing out due to the bridging phenomenon caused by the viscous resistance of the soil, even if it allows the soil to flow out temporarily at the initial stage of soil filling, and the root system overhangs as the seedling grows. In this case, this root passage supports the growth of the roots in the planting soil, and the growth of the seedlings can be promoted.

(Claim 7) Between the front sheet and the back sheet, a soil culture temporary fixing sheet that is broken at the time of planting may be interposed.
In this way, the cut of the front sheet is closed by the culture temporary tacking sheet, so that when the culture soil is filled through the filling port into the space that appears between the temporary clay fastening sheet and the back sheet, It is possible to prevent the occurrence of soil leakage without opening, and to easily tear the cultivated soil temporary fixing sheet at the time of planting to secure an opening.

(Claim 1) According to the present invention, the length from the center of the radial cut formed in the front sheet is sufficient as long as it can provide an opening of the area necessary for planting, so the space between the front and back sheets is filled. When the soil is filled through the mouth, even if the cut is opened at the middle part due to the earth pressure of the soil, the soil can be regulated to the extent that the soil does not leak to the outside. When planting, the opening area necessary for planting can be secured parallel to the cultivated soil surface by simply inverting the concentrated part of the cut to the outside or inside of the front sheet. It can be done easily and quickly by one person as well as by several people. In addition, although the root passage is formed in the back sheet, the opening area of the root passage is small, and the soil is viscous, and its resistance causes a bridging phenomenon near the root passage, preventing further leakage. It can be rooted effectively and can be planted well.

  According to the second aspect, even when the maximum capacity of the soil is filled in the space between the front sheet and the back sheet, the length of the cut is regulated at the concentrated portion, so that the mouth of the cut opens to a certain extent. It prevents the leakage of the soil.

  According to claim 3, since it is not necessary to make the length of the cut when filling the culture soil, there is little risk of leakage of the culture soil, and when the plant to be planted is large, the cut is opened to the planned incision portion and opened. Can be increased and planting can be performed easily.

  According to claim 4, since the incision portion that is continuous on the extension of at least one of the cuts is formed in the concentrated portion, the concentrated portion can be easily broken at the planned incision portion when planting a seedling. Wide opening can be secured.

  According to the fifth aspect, even if the earth pressure at the time of filling the cultivating soil is large, the concentrated portion receives this, so that the cuts are not expanded at the same time and soil leakage does not occur.

  According to claim 6, even if the root passage allows the outflow of the soil temporarily at the initial stage of the soil filling, the root passage can prevent the subsequent outflow due to the bridging phenomenon due to the viscous resistance of the soil. When the root system is overhanging, the root passages support the growth of the roots in the planting soil, and the growth of the seedlings can be promoted.

  According to claim 7, since the cut of the front sheet is closed by the culture soil temporary fixing sheet, when filling the culture soil through the filling port into the space appearing between the culture soil temporary fixing sheet and the back sheet, The cuts do not open due to earth pressure, so that the occurrence of soil leakage can be prevented, and the cultivation soil temporary fixing sheet can be easily torn off at the time of planting to secure an opening.

  In the following description, the same reference numerals indicate the same or corresponding parts.

The description up to paragraph 0038 below is made with reference to FIGS.
(Claim 1) 1 is a front sheet, 2 is a back sheet. The front sheet 1 is made of a water-impermeable material and includes radial cuts 12 that provide openings 11 parallel to the surface of the culture soil that is necessary for planting and that is filled in the planting article.
The back sheet 2 is composed of a non-woven fabric having water permeability and air permeability, and the area is smaller than that of the front sheet 1 and a root passage 21 is formed.
The back sheet 2 is attached to the front sheet 1 so as to cover the cut 12 of the front sheet 1 and leave a portion that becomes the filling port 22. For attachment, an appropriate method such as adhesion, welding, or sewing with a thread S can be adopted.

The front sheet 1 desirably has biodegradability, water resistance, corrosion resistance, and strength sufficient to prevent tearing by a human pulling force. For example, a three-layer structure made of polyethylene is used.
The number of the cut lines 12 and the angle when a plurality of cut lines 12 intersect are determined as appropriate, but in the illustrated example, the two cut lines 12 are arranged at 90 ° from each other at the center of the front sheet 1. Is shown. The length of the cut line 12 is set to a length that can provide the opening 11 having an area necessary for planting, so that the cultivated soil does not flow out even if it is slightly opened by earth pressure.

  Further, like the front sheet 1, the back sheet 2 desirably has biodegradability, water resistance, and corrosion resistance. The strength of the back sheet 2 is sufficient if it is not broken by the earth pressure when the soil M is filled in the space H that appears apart from the front sheet 1.

  A root passage 21 is formed in the back sheet 2. Although the number may be suitable, it is preferable to scatter a plurality. Moreover, the opening area should just be a grade which the root R can enter in the soil of the planting surface G through this root channel | path 21, and the cultivation soil M does not leak.

  In this planting article, the filling port 22 is opened so as to peel off the front and back sheets 1 and 2, and the culture soil M is filled through the filling port 22 into the space H that appears between the front and back sheets 1 and 2. As it is filled, it is expanded at the concentrated portion 13 of the cut 12 of the front sheet 1 by the earth pressure of the cultivating soil M. However, since the length of the cut 12 is regulated, it does not expand any more if it expands to some extent. Therefore, even if the cultivating soil M is in a state where the concentrated portion 13 is expanded, it hardly leaks through the soil M.

  Further, the back sheet 2 also receives the earth pressure by filling the culture medium M into the space H. Although the opening area of the root passage 21 is small, a part of the soil M may leak to the outside through the root passage 21 due to an impact during filling. However, the cultivating soil M is viscous, and the resistance causes a bridging phenomenon in the vicinity of the root passage 21, so that further leakage is prevented.

  When filling of the soil M is finished, the filling port 22 is closed. For this closure, clips, sewing, pinning, bonding or other suitable methods can be employed.

  A seedling T is disposed on a planting product with the filling port 22 closed. The concentrated portion 13 of the cut 12 of the front sheet 1 is reversed to the outside of the front sheet. This inversion provides a planting opening 11 parallel to the surface of the soil M. A seedling T is prepared, its leaves and leaves are left outside the planting article, and its root R is embedded in the cultivation soil M through the opening 11.

  The planting material provided with the seedlings T thus produced is installed with the planting surface G facing the planting surface G and the back sheet 2 facing the planting surface G. The root R of the seedling T grows in the soil of the planting surface G through the root passage 21 of the back sheet 2.

(Claim 2) In FIGS. 4 to 6, the cut 12 is discontinuous at the concentrated portion 13. FIG.
In this case, even if the maximum volume of the soil M is filled in the space H between the front sheet 1 and the back sheet 2, the length of the cut 12 is regulated by the concentrated portion 13, so The mouth does not open and prevents the soil M from leaking out.

(Claim 3) Returning to FIG. 1 and FIG. 2, the cut line 12 is provided with a planned incision 14 on its radial extension. The planned incision 14 is intended to be easily incised manually without tools such as a blade, and appropriate means such as perforations and kerfs can be employed.
In this case, since the length of the cut 12 when filling the culture soil M is not excessive, there is little risk of the culture soil M leaking, and when the seedling T to be planted is large, the cut 12 is extended to the planned incision portion 14. Thus, the area of the opening 11 can be increased and planting can be performed easily.

(Claim 4) Referring again to FIGS. 4 to 6, the concentrated portion 13 is formed with a continuous incision portion 14 'on the extension of at least one cut 12. This planned incision 14 ′ is also provided for the same purpose as the planned incision 14 described in the previous paragraph 0040, and the configuration is the same.
In this case, at the time of planting a seedling, the concentrated portion 13 can be easily broken at the planned incision portion 14 ′ to ensure a wide opening 11.

(Claim 5) The concentrated portion 13 has a strength capable of withstanding the pressure of the maximum volume of the soil M filled in the space H that appears between the front sheet 1 and the back sheet 2.
In this case, even if the earth pressure at the time of filling the cultivating soil M is large, the concentrated portion 13 receives this, so that the cuts 12 do not spread all at once and cause soil leakage.

(Claim 6) In FIGS. 2, 5 and 7, the root passage 21 has a size that prevents the leakage of the soil M filled in the space H appearing between the front sheet 1 and the back sheet 2 in the opening area. It has become.
In this case, even if the root passage 21 allows the outflow of the soil M temporarily in the initial stage of the soil filling, the root passage 21 can prevent the subsequent outflow due to the bridging phenomenon due to the viscous resistance of the soil M. When the root system R is accompanied, the root passage 21 supports the growth of the roots in the planting soil, and the growth of the seedling T can be promoted.

(Claim 7) In FIG. 7, between the front sheet 1 and the back sheet 2, a temporary fixing sheet 3 of a soil to be broken at the time of planting is interposed.
In this case, since the cut 12 of the front sheet 1 is closed by the temporary fixing sheet 3, when the culture soil M is filled into the space H that appears between the temporary fixing sheet 3 and the back sheet 2 through the filling port 22, Since 12 does not open due to earth pressure, the occurrence of earth leakage can be prevented.
