Description

[Technical Field]

[0001] The present invention relates to an insect-proof bag that mainly prevents insect damage to leafy vegetables, and a method for planting seedlings using the insect-proof bag. [Background technology]

[0002] Leafy vegetables such as cabbage, Chinese cabbage, komatsuna (Japanese mustard spinach), spinach, broccoli, and cauliflower are susceptible to insect damage, so a cultivation method has been known in which the plants are covered with a nonwoven fabric called cheesecloth or a net-like cloth to physically prevent the invasion of pests.

[0003] Various protective devices have been proposed as methods for physically preventing the intrusion of pests as described above. For example, Patent Document 1 proposes a protective device in which a plate-shaped pest barrier is provided around a plant and a net is loosely placed over the plant above the pest barrier. Patent Document 2 describes an insect-repellent net, which shows that the insect-repellent effect is confirmed by covering plant seedlings with a bag-shaped net. Patent Document 3 describes a tapered cylindrical plant protective cover whose diameter increases downward. [Prior art documents] [Patent documents]

[0005] As described above, measures to prevent damage caused by various insects involve covering the plant seedlings with various protective devices after planting, which requires a lot of work after planting the plants.

[0006] Therefore, the present invention aims to provide an insect-proof bag that can effectively prevent insect invasion while reducing the labor required for planting, and a method for planting seedlings using the insect-proof bag. [Means for solving the problem]

[0007] The insect-proof bag of the present invention is characterized by comprising an upper sheet body that prevents the intrusion of pests, a lower sheet body that is formed with the same outer edge shape as the upper sheet body and also prevents the intrusion of pests, a fastening portion that overlaps the upper sheet body and the lower sheet body and fastens them to each other along the entire length of their outer edges, an upper insertion portion that is provided in the center of the upper sheet body and into which a seedling can be inserted, a lower insertion portion that is provided in the center of the lower sheet body and into which a root ball including the roots of the seedling can be inserted, and a closing means that closes the upper insertion portion.

[0008] The insect-proof bag of the present invention is characterized in that the upper insertion portion is formed by cutting in a straight line.

[0009] The insect-proof bag of the present invention is characterized in that the lower insertion part is formed by cutting into three or more straight lines extending radially from the center.

[0010] The insect-proof bag of the present invention is characterized in that the closing means is formed so as to be openable and closable.

[0011] The seedling planting method of the present invention is characterized by comprising a hole making step of making a planting hole in the soil surface, a bag placing step of placing the insect-proof bag body described in claim 4 on the soil surface so as to cover the planting hole, a planting step of inserting the seedling into the insect-proof bag body through the upper insertion part and planting the root ball part including the roots of the seedling into the soil surface through the lower insertion part, and a closing step of closing the upper insertion part above the seedling with a closing means.

[0012] The seedling planting method of the present invention is characterized in that the planting step includes bending the side edge of the lower insertion part downward and burying it between the planting hole and the root ball of the seedling.

[0013] The seedling planting method of the present invention is characterized in that the upper sheet body and the lower sheet body are formed into a circular shape, and the bag placing process is carried out after folding the outer peripheral portions of the insect-proof bag body in a position closer to the outer edge than the center when the upper sheet body and the lower sheet body are stacked flat. [Effects of the Invention]

[0014] According to the insect control bag of the present invention, the upper and lower sheet bodies have the same outer edge shape, and when the upper and lower sheet bodies are stacked, the entire length of their outer edges is fixed to each other to form a fixed portion, thereby forming a bag-like shape with the upper and lower sheet bodies, into which seedlings can be inserted to prevent pest intrusion. The upper sheet body has an upper insertion portion in its center into which a seedling can be inserted, and the lower sheet body has a lower insertion portion in its center into which a root ball containing the seedling's roots can be inserted. The insect control bag can be placed on a soil surface with a planting hole, and the seedling can be inserted into the insect control bag through the upper insertion portion. The root ball containing the seedling's roots can then be planted in the soil through the lower insertion portion. Closing the upper insertion portion with the closing means prevents pest intrusion. Therefore, after planting the seedlings, the only thing that needs to be done is to close the upper insertion portion, simplifying the seedling planting process.

[0015] According to the insect repellent bag of the present invention, the upper insertion part is cut in a straight line, which simplifies the manufacturing process of the insect repellent bag and reduces manufacturing costs. Furthermore, the straight line makes it easy to close the upper insertion part. Furthermore, the straight line allows the closing means itself to have a simple structure.

[0016] According to the insect-proof bag of the present invention, the lower insertion portion is formed by cutting it into three or more straight lines extending radially from the center, so that when planting the root ball containing the roots of a seedling in the soil through the lower insertion portion, the root ball can be easily passed through the lower insertion portion, and the area around the cut portion is woven downward and buried in the soil, preventing the invasion of root-cutting insects and suppressing insect damage to the seedling's roots.

[0017] According to the insect-proof bag of the present invention, the closing means is formed so as to be openable and closable, and therefore it can be reopened even after being closed once, so that if there is a problem, it can be redone and the insect-proof bag can be reused after the plant has grown.

[0018] The seedling planting method of the present invention includes a hole making step of making a planting hole in the soil surface, a bag placing step of placing an insect-proof bag body on the soil surface so as to cover the planting hole, a planting step of inserting the seedling into the insect-proof bag body through the upper insertion part and planting the root ball part including the roots of the seedling into the soil surface through the lower insertion part, and a closing step of closing the upper insertion part above the seedling with a closing means.Therefore, after planting the seedling in the soil surface, the work can be completed simply by closing the upper insertion part, thereby reducing the amount of work required.

[0019] According to the seedling planting method of the present invention, by bending the side edge of the lower insertion part downward and burying it between the planting hole and the root ball of the seedling, it is possible to inhibit the invasion of root-cutting insects and suppress insect damage to the seedling's roots.

[0020] According to the seedling planting method of the present invention, the upper and lower sheet bodies are formed into a circular shape, and the outer peripheral portions of the insect-proof bag body, in which the upper and lower sheet bodies are stacked flat, are folded at a position closer to the outer edge than the center, and then the bag placement process is carried out.Therefore, while the seedlings are small, workability can be improved by keeping the insect-proof bag body in a small state, and after the seedlings have grown larger, the folded portions can be unfolded so as not to hinder growth.

[0022] Hereinafter, an embodiment of an insect-proof bag 1 and a seedling planting method of the present invention will be described with reference to the drawings. The insect-proof bag 1 covers a vegetable or other plant seedling 8, physically inhibiting the invasion of pests such as slugs, pillbugs, aphids, cutworm moths, cabbage white butterflies, and beetles, thereby protecting the plant from damage caused by the pests. Examples of plants that can be cultivated using the insect-proof bag 1 include vegetables such as Chinese cabbage, Japanese mustard spinach, spinach, cabbage, lettuce, Chinese cabbage, cauliflower, and broccoli. Note that the plants that can be cultivated using the insect-proof bag 1 are not limited to those mentioned above, and the insect-proof bag 1 can be used for various plants that can be cultivated by inserting a seedling 8 into the insect-proof bag 1.

[0023] The insect-proof bag 1 of this embodiment comprises an upper sheet body 2 that prevents the intrusion of pests, a lower sheet body 3 that is formed with the same outer edge shape as the upper sheet body 2 and also prevents the intrusion of pests, and a fastening portion 4 that overlaps the upper sheet body 2 and the lower sheet body 3 and fastens them to each other along the entire length of their outer edges. The upper sheet body 2 is made of a synthetic fiber cloth such as polyethylene, polyester, nylon, or vinylon, and is formed into a mesh shape with a mesh size of, for example, about 0.4 mm. The upper sheet body 2 is in the form of a circular, flat sheet, with a diameter ranging from, for example, 750 mm to 800 mm. The material, shape, and dimensions of the upper sheet body 2 are not limited to those described above, and appropriate materials, shapes, and dimensions can be used depending on factors such as the type and size of the plants being cultivated and the size of the pests that need to be prevented from invading.

[0024] An upper insertion section 5 into which a seedling 8 can be inserted is formed in the center of the upper sheet body 2. Here, "center" means that the upper insertion section 5 includes the center point of the circular upper sheet body 2. The upper insertion section 5 is formed by cutting in a straight line, for example, 150 mm long, including the center point of the upper sheet body 2. The dimensions of the upper insertion section 5 are not limited to these, and it may be any size that allows the entire seedling 8 to be inserted.

[0025] The upper insertion section 5 is provided with a closing means 7 for closing the upper insertion section 5. The closing means 7 may be a fastener such as staples driven in by a stapler or adhesive tape, or may be a linear fastener in which rows of teeth on both sides engage with each other using a slider, a rail fastener in which rails on both sides engage with each other using a slider, or a hook-and-loop fastener. The closing means 7 preferably has a structure that can be repeatedly opened and closed like various fasteners. Note that the closing means 7 is not limited to those listed above, and may be any structure that can close the upper insertion section 5 and prevent pests from entering through the upper insertion section 5.

[0026] The upper insertion part 5 is cut and formed in a straight line, which simplifies the processing work in the manufacturing process of the insect repellent bag 1 and reduces manufacturing costs. Furthermore, because it is in a straight line, the upper insertion part 5 can be easily closed, and the straight line allows the closing means 7 itself to have a simple configuration.

[0027] The lower sheet body 3, like the upper sheet body 2, is made of synthetic fiber cloth such as polyethylene, polyester, nylon, or vinylon, and is formed into a mesh shape with a mesh size of about 0.4 mm. The lower sheet body 3 is a circular sheet with the same shape as the upper sheet body 2, for example, with a diameter of 750 mm to 800 mm. Note that the material, shape, and dimensions of the lower sheet body 3 are not limited to these, and appropriate material, shape, and dimensions are used depending on factors such as the type and size of the plants to be cultivated and the size of the pests that need to be prevented from entering.

[0028] The lower sheet body 3 has a central lower insertion section 6 into which a root ball 9 containing the roots of a seedling 8 can be inserted. The root ball 9 refers to the mass of roots and soil that emerges when a seedling 8 grown in a seedling pot or planter (not shown) is removed from the seedling pot or dug up from the planter, and is buried below the soil surface 10 when the seedling 8 is planted. The center of the lower sheet body 3, like the center of the upper sheet body 2, refers to the portion that includes the center point of the circular lower sheet body 3. The lower insertion section 6 is formed radially from the center point of the lower sheet body 3. In this embodiment, the lower insertion section 6 is a cross-shaped cut formed by two orthogonal straight cuts. Each of the two orthogonal straight cuts in the lower insertion section 6 is 100 mm. The dimensions of the lower insertion section 6 are not limited to these dimensions, and may be any size that allows the root ball 9 of the seedling 8 to be inserted therein. Furthermore, the lower insertion portion 6 is not limited to a cross shape, but may be any shape as long as it is a linear cut extending radially in three or more directions from a central point.

[0029] In the insect repellent bag 1, the upper sheet body 2 and the lower sheet body 3 are overlapped with each other, and their outer peripheral edges are fastened together along their entire length to form a fastening portion 4. The fastening portion 4 is formed, for example, in a range extending from the entire length of the outer peripheral edges of the upper sheet body 2 and the lower sheet body 3 to a position approximately 5 mm inward, and the upper sheet body 2 and the lower sheet body 3 are fastened together by thermal welding. The fastening portion 4 is not limited to thermal welding, and may be, for example, sewn, or bonded with an adhesive.

[0030] As described above, the insect-proof bag 1 is formed into a bag shape by closing the outer peripheral edges of the upper sheet body 2 and the lower sheet body 3, with the upper insertion section 5 opening at the center of the upper sheet body 2 and the lower insertion section 6 opening at the center of the lower sheet body 3. The upper sheet body 2 and the lower sheet body 3 are arranged in an overlapping position, so that the seedling 8 can be inserted from above the upper insertion section 5 and then the root ball 9 can be inserted directly into the lower insertion section 6, thereby improving the workability of planting the seedling 8. Furthermore, as described above, the upper sheet body 2 and the lower sheet body 3 of the insect-proof bag 1 are made of the same material and have the same outer edge shape, and the upper sheet body 2 and the lower sheet body 3 are overlapped and fastened to each other along the entire length of their outer peripheral edges to form the fastening section 4, so that the insect-proof bag 1 can be manufactured relatively easily and at low manufacturing costs.

[0031] When planting seedlings 8 using the insect-proof bag 1, first, the outer peripheral portion 12 is folded downward to form a square. More specifically, the portion 12 including the arc that is closer to the outer peripheral edge than the center of the insect-proof bag 1 is folded downward so as to form a square whose diagonals are two diametric lines that intersect at right angles at the center point of the insect-proof bag 1 when the circular upper sheet body 2 and lower sheet body 3 are overlapped. In this way, by performing the bag placement step after folding the outer peripheral portion 12, the insect-proof bag 1 can be kept small while the seedlings 8 are small, which improves workability, and once the seedlings 8 have grown, the folded portion can be unfolded so as not to hinder growth.

[0032] (hole drilling process) Next, ridges are formed on the soil surface 10 and covered with mulching material 11 as needed. Then, a hole-making process is carried out in which a cylindrical hole punch 13 is used to make holes in the mulching material 11 and to make planting holes 14 in the soil surface 10. The planting holes 14 made in the hole-making process are formed to a size that allows the root ball 9 of the seedling 8 to be planted.

[0033] (Bag placement process) Thereafter, a bag placing step is carried out in which the insect-proof bag 1 is placed on the mulch 11 laid on the soil surface 10 so as to cover the planting hole 14 formed in the hole making step. The insect-proof bag 1 is folded into a square and formed compactly, which makes the bag placing step of placing the insect-proof bag 1 easy. In the bag placing step, the insect-proof bag 1 is placed so that the upper insertion portion 5 of the upper sheet body 2 and the lower insertion portion 6 of the lower sheet body 3 of the insect-proof bag 1 overlap the planting hole 14.

[0034] (Planting process) Then, seedling 8 is inserted into the insect-proof bag through upper insertion portion 5, and root ball 9 of seedling 8 is inserted into planting hole 14 through lower insertion portion 6, and seedling 8 is planted in planting hole 14. At this time, because lower insertion portion 6 is notched in a cross shape, side portions 15 formed between the notches of lower insertion portion 6 are bent downward and buried between planting hole 14 and root ball 9 of seedling 8. In this way, side portions 15 between the notches of lower insertion portion 6 are woven downward and buried below soil surface 10, forming an area about 1 to 2 cm above ground level that root-cutting insects cannot invade, thereby inhibiting the intrusion of root-cutting insects and suppressing insect damage to the roots of seedling 8.

[0035] (Closing process) After the seedlings 8 are planted in the planting step described above, a closing step is then performed in which the upper insertion section 5 formed in the upper sheet body 2 is closed while the seedlings 8 are stored inside the insect-proof bag body 1. For example, both sides of the linearly formed upper insertion section 5 are overlapped, and staples serving as closing means 7 are driven into the overlapping portion with a stapler to close the upper insertion section 5. The closing means 7 may be achieved by, for example, applying waterproof adhesive tape over the upper insertion section 5 formed by linearly cutting it, or by previously fixing teeth of a wire fastener and rails of a rail fastener to both sides of the upper insertion section 5 and sliding a slider to close it. Alternatively, the upper insertion section 5 may be closed by providing a male side of a hook-and-loop fastener on one side and a female side on the other, and then mating and fastening the two together.

[0036] If the closing means 7 is configured to be openable and closable multiple times, such as a wire fastener, rail fastener, or hook-and-loop fastener, it can be reopened even after being closed once, allowing for redoing in case of a problem, and also making it easy to reuse the insect-proof bag 1 after the plants have grown.

[0037] In this way, the upper insertion portion 5 is closed with the seedling 8 inserted between the upper sheet body 2 and the lower sheet body 3, thereby suppressing the intrusion of pests and preventing damage to the seedling 8. The seedling 8 is planted by inserting the root ball 9 into the planting hole 14 through the upper insertion portion 5 and the lower insertion portion 6, so there is no need to go through the trouble of covering the seedling 8 with an insect net after planting, and after planting the seedling 8, it is only necessary to close the upper insertion portion 5 with the closing means 7, thereby improving the workability of the seedling 8 planting operation.

[0038] It goes without saying that the embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the concept of the present invention. [Industrial Applicability]
