[0005] As described above, measures against 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, an object of the present invention is 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 prevents the intrusion of pests, a fastening portion in which the upper sheet body and the lower sheet body are overlapped and fixed to each other along the entire length of their outer edges, an upper insertion portion provided in the center of the upper sheet body and into which a seedling can be inserted, a lower insertion portion 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 for closing 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 portion 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 a 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 portion and planting the root ball portion including the roots of the seedling into the soil surface through the lower insertion portion, and a closing step of closing the upper insertion portion over the seedling with a closing means.

[0012] In the seedling planting method of the present invention, the planting step is characterized in that the side edge portion of the lower insertion portion is folded downward and buried 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 state in which the upper sheet body and the lower sheet body are stacked flat and located closer to the outer peripheral edge than the center. Effect of the Invention

[0014] According to the insect-proof bag of the present invention, the outer edge shapes of the upper sheet body and the lower sheet body are the same, and when the upper sheet body and the lower sheet body are stacked, the entire length of the outer periphery of each sheet body is fixed to form a fixed part, so that the upper sheet body and the lower sheet body form a bag shape, and the intrusion of pests can be suppressed by inserting a seedling inside. The upper sheet body has an upper insertion part in which the seedling can be inserted at the center, and the lower sheet body has a lower insertion part in which the root ball part including the roots of the seedling can be inserted at the center. Therefore, the insect-proof bag is placed on a soil surface with a planting hole, and the seedling is inserted into the insect-proof bag body from above through the upper insertion part, and the root ball part including the roots of the seedling can be planted in the soil through the lower insertion part, and the intrusion of pests can be suppressed by closing the upper insertion part with the closing means. Therefore, after planting the seedling, it is only necessary to close the upper insertion part, so that the seedling planting work can be simplified.

[0015] According to the insect-proof bag of the present invention, the upper insert part is cut and formed in a straight line, so that the processing work in the manufacturing process of the insect-proof bag can be simplified and the manufacturing cost can be reduced. Also, since it is in a straight line, the work of closing the upper insert part can be made easy. Furthermore, since it is in a straight line, the closing means itself can be made of a simple structure.

[0016] According to the insect-proof bag of the present invention, the lower insertion part is formed by cutting into three or more straight lines extending radially from the center, so that when planting the root ball including the roots of a seedling into the soil through the lower insertion part, the root ball can be easily passed through the lower insertion part, and the area around the cut part 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 it has been closed once, so that redoing is possible in case of a malfunction, and the insect-proof bag can also 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 portion including the roots of the seedling on 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 on 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, the side edge of the lower insertion part is folded downward and buried between the planting hole and the root ball of the seedling, thereby preventing the invasion of root-cutting insects and suppressing 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 portion of the insect-proof bag body in which the upper and lower sheet bodies are stacked flat is folded at a position closer to the outer peripheral edge than the center, and then the bag placement process is carried out. Therefore, while the seedlings are small, the insect-proof bag body can be kept small to improve workability, and after the seedlings have grown larger, the folded portion can be unfolded, so that growth is not hindered.

[0022] Hereinafter, an embodiment of the insect-proof bag 1 and the seedling planting method of the present invention will be described with reference to the drawings. The insect-proof bag 1 covers the seedling 8 of a plant such as a vegetable, and physically suppresses the intrusion of pests such as slugs, pillbugs, aphids, cutworm moths, cabbage white butterflies, and beetles, thereby protecting the plant from damage caused by pests. Examples of plants that can be cultivated using the insect-proof bag 1 include vegetables such as Chinese cabbage, Japanese mustard 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 the seedling 8 into the insect-proof bag 1.

[0023] The insect-proof bag 1 of this embodiment has an upper sheet body 2 that prevents the intrusion of pests, a lower sheet body 3 that is formed in the same outer edge shape as the upper sheet body 2 and prevents the intrusion of pests, and a fixing part 4 in which the upper sheet body 2 and the lower sheet body 3 are stacked and fixed to each other over the entire length of their outer edges. The upper sheet body 2 is made of synthetic fiber cloth such as polyethylene, polyester, nylon, vinylon, etc., and is formed in a mesh shape with a mesh size of about 0.4 mm. The upper sheet body 2 is a circular flat sheet, and has a diameter in the range of 750 mm to 800 mm, for example. The material, shape, and dimensions of the upper sheet body 2 are not limited to those mentioned above, and appropriate materials, shapes, and dimensions are used depending on factors such as the type and size of the plant to be cultivated and the size of the pests that need to be prevented from invading.

[0024] An upper insertion section 5 into which the seedling 8 can be inserted is formed in the center of the upper sheet body 2. Here, the 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, with a length of 150 mm, 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 of any size as long as the entire seedling 8 can be inserted therein.

[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 line fastener in which teeth arranged in a row on both sides are engaged with each other by a slider, a rail fastener in which rails arranged on both sides are engaged with each other by a slider, or a hook-and-loop fastener. The closing means 7 is preferably structured to 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] Since the upper insertion part 5 is cut and formed in a straight line, it is possible to simplify the processing work in the manufacturing process of the insect-proof bag 1, and it is possible to reduce the manufacturing cost. In addition, since it is in a straight line, it is possible to easily close the upper insertion part 5, and since it is in a straight line, it is possible to make the closing means 7 itself have a simple structure.

[0027] The lower sheet body 3, like the upper sheet body 2, is made of synthetic fiber cloth such as polyethylene, polyester, nylon, vinylon, etc., and is formed in a mesh shape with a mesh size of about 0.4 mm. The lower sheet body 3 is a circular sheet having 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 plant to be cultivated and the size of the pests that need to be prevented from entering.

[0028] The lower sheet body 3 has a lower insertion section 6 formed in the center thereof into which a root ball 9 including the roots of the seedling 8 can be inserted. The root ball 9 here refers to a lump of roots and soil that is produced when the seedling 8 cultivated in a seedling pot or a planter (not shown) is pulled out of the seedling pot or dug out of the planter, and refers to a portion that is buried under the soil surface 10 when the seedling 8 is planted. The center of the lower sheet body 3 refers to a portion that includes the center point of the circular lower sheet body 3, similar to the center of the upper sheet body 2, and the lower insertion section 6 is formed radially including the center point of the lower sheet body 3. In this embodiment, the lower insertion section 6 is a cross-shaped cut that is cut into two straight lines that intersect at right angles. The straight lines of the two orthogonal cuts of the lower insertion section 6 are each 100 mm. The dimensions of the lower insertion section 6 are not limited to these, and may be any size that allows the root ball 9 of the seedling 8 to be inserted. 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-proof bag 1, the upper sheet body 2 and the lower sheet body 3 are overlapped with each other, and their outer peripheral edges are fixed to each other along their entire length at the fixed portion 4. The fixed portion 4 is formed, for example, in a range from the entire length of the outer peripheral edges of the upper sheet body 2 and the lower sheet body 3 to about 5 mm inward, and the upper sheet body 2 and the lower sheet body 3 are fixed to each other by thermal welding. The fixed 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 in a bag shape by closing the outer peripheries of the upper sheet body 2 and the lower sheet body 3, and the upper insertion part 5 is opened at the center of the upper sheet body 2, and the lower insertion part 6 is opened 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, and the seedling 8 can be inserted from above the upper insertion part 5, and the root ball part 9 can be inserted as it is into the lower insertion part 6, so that the workability of planting the seedling 8 can be improved. In addition, 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 fixed to each other over the entire length of their outer peripheries to form the fixed part 4, so that the insect-proof bag 1 can be manufactured relatively easily and the manufacturing cost can be reduced.

[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 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 diagonal is two straight lines of diameters that intersect at right angles at the center point of the insect-proof bag 1 when the upper sheet body 2 and the lower sheet body 3 formed in a circular shape are overlapped. In this way, by performing the bag placement process after folding the portion 12 including the arc on the outer peripheral side, the insect-proof bag 1 can be kept in a small state while the seedlings 8 are small, thereby improving workability, and after the seedlings grow, the folded portion can be unfolded to prevent growth from being hindered.

[0032] (hole drilling process) Next, ridges are formed on the soil surface 10 and covered with mulching material 11 as necessary. Then, a hole making process is performed in which a cylindrical hole puncher 13 is used to make holes in the mulching material 11 and planting holes 14 are made 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 performed in which the insect-proof bag 1 is placed on the mulching material 11 provided on the soil surface 10 so as to cover the planting hole 14 formed in the hole making step. Since the insect-proof bag 1 is folded into a square and formed compactly, the bag placing step of placing the insect-proof bag 1 is 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, the seedling 8 is inserted into the insect-proof bag through the upper insertion part 5, and the root ball part 9 of the seedling 8 is inserted into the planting hole 14 through the lower insertion part 6, and the seedling 8 is planted in the planting hole 14. At this time, the lower insertion part 6 is cut into a cross shape, so that the side parts 15 formed between the cuts of the lower insertion part 6 are folded downward and buried between the planting hole 14 and the root ball part 9 of the seedling 8. In this way, the side parts 15 between the cross-cut lower insertion parts 6 are woven downward and buried under the soil surface 10, so that a part where root-cutting insects cannot enter is formed at a position about 1 to 2 cm above the ground, and therefore the entry of the root-cutting insects is inhibited and insect damage to the roots of the seedling 8 can be suppressed.

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

[0036] If the closing means 7 is a structure that can be opened and closed repeatedly, such as a wire fastener, rail fastener, or hook-and-loop fastener, it can be reopened even after it has been closed once, allowing redoing in case of a malfunction, and also making it easy to reuse the insect-proof bag 1 after the plants have grown.

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

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