Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention mainly relates to improvement of a plant runner attracting tool that fixes and attracts above-ground stems and branches (hereinafter collectively referred to as runners) of strawberries, melons, watermelons, pumpkins, etc. on the surface of the growing area. is there.

[0002]

[Prior art]

 Conventionally, this type of attracting tool has been used to fix the stems and branches of plants. For example, the attracting device described in Japanese Utility Model Publication No. 6-29017 has a spring property, and is used mainly for guiding plant stems and the like upward. In addition, the attraction tool described in Japanese Utility Model Publication No. 5-3005 is one in which a notch is formed in a part of the cylindrical body so that it can be easily attached to the stem of a plant, and an opening / closing member is provided in this notch. Is. And this attracting tool is also used mainly for guiding the stems and the like of plants upward.

[0003] Furthermore, in a strawberry, melon, watermelon, pumpkin or the like in which a runner breeds on the ground, an attracting tool for fixing the runner on the ground is generally used. This attracting tool prevents the seedlings from moving due to wind, and is made of materials such as straw, paper and wire.

[0004]

[Problems to be solved by the device]

 The present invention is to remove a used attracting tool without affecting plants. In other words, the attracting tool that fixes the runner to the ground is not only used for many purposes but also remains buried on the ground surface. Therefore, if the attractor made of a material such as wire is left as it is, it not only hinders the next cropping, but also this attractor may adversely affect the growth of plants. Also, attracting tools such as wheat straw and paper materials rot and decompose naturally over time, so they have relatively little effect on plants and the like compared to materials such as wire. However, attracting tools such as wheat straw and paper materials have poor mechanical strength, so that workability is extremely poor and, furthermore, there is a problem that they are weak against moisture. For this reason, especially when used in the rainy season, such as strawberry cultivation, not only is the lure of the attractor weak and it becomes difficult to insert it into the ground surface, but also the attracting force of the attached attractor is poor due to moisture. There was also an inconvenience.

On the other hand, the conventional attracting tool that is mainly used for guiding the stems of plants upward can check the usage state at a glance, but when removing it, the same work as when installing it is required. , It is unsuitable as an attracting tool for fixing many runners to the ground.

Therefore, the present invention has been devised to solve the above-mentioned problems, and it has extremely good workability when mounted, and it does not damage the runner when fixing it, and it also allows the used attracting tool to be used naturally. The purpose of the present invention is to provide a plant runner attraction tool that can be removed.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the first means of the present invention, a biodegradable plastic is formed into a thin rod shape that can be bent into a substantially V shape with a fingertip, and the surface of a plant growing surface is This is because the inserting and fixing portions to be inserted into the rod body are provided at both ends of the rod body, and the runner locking portions that engage with the side surfaces of the runner are provided at the bent portions of the rod body.

In the second means, a filler made of an inorganic material or an organic material is mixed in the biodegradable plastic, and the biodegradable plastic is formed into a bendable thin rod body.

Further, as a third means, a filler is mixed with an aliphatic polyester having a number average molecular weight of at least 10,000 and a melting point of 70 ° C. or higher, which is synthesized from glycol and an aliphatic dicarboxylic acid or an acid derivative thereof. A biodegradable plastic that is a polyester resin plastic and has a melt viscosity of 1 × 10 ³ to 1 × 10 ⁵ poise at a temperature of 190 ° C and a shear rate of 1,000 sec ^-1 was formed into a flexible thin rod. Is the means for solving the problem.

[0010]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the drawings. The present invention is made of biodegradable plastic, and its shape is a thin rod shape that can be bent into a substantially V shape with a fingertip (see Fig. 1). The rod 1 has a diameter of about 0.5 mm to 10 mm and mainly attracts runners P such as strawberries, melons, watermelons and pumpkins. The rod 1 has a circular, elliptical, or polygonal cross-sectional shape. Particularly, by making the polygonal shape, it becomes difficult to slip and easy to handle during work, and when it is formed into a circular or elliptical shape. Thus, the contact portion of the runner P can be further protected (see FIGS. 2A to 2C).

Then, both ends of the bar body 1 bent into a substantially V shape serve as insertion fixing portions 1A that are inserted into the surface of the growing area of the plant. The bent portion of the rod 1 serves as a runner locking portion 1B, which locks the side surface of the runner P. The insertion fixing portion 1A needs to have mechanical strength so that it can be easily inserted into the ground surface. Further, the runner engaging portion 1B is required to be supple so as not to damage the runner P, and also tough enough to withstand the humidity during the rainy season.

Therefore, the rod body 1 of the present invention has a strength of the rod body 1 which is made by mixing a biodegradable plastic with a filler composed of 50% to 60% by weight of an inorganic substance or a few% of an organic substance. It makes it easier to insert it on the ground surface and speeds up disassembly. Calcium carbonate or talc is used as the material of the inorganic filler, and coconut husk or the like is used as the material of the organic filler. It is particularly preferable to use calcium carbonate as an inorganic filler.

As for biodegradable plastics, biodegradable plastics called “Bionore”, which is a registered trademark jointly developed by Showa High Polymer Co., Ltd. and Showa Denko Co., Ltd., is the most suitable as the attracting tool of the present invention. Proved to be This biodegradable plastic is a polyester resin plastic compound prepared by mixing a filler with an aliphatic polyester having a number average molecular weight of at least 10,000 and a melting point of 70 ° C or higher synthesized from glycol and an aliphatic dicarboxylic acid or its derivative. It has a melt viscosity of 1 × 10 ³ to 1 × 10 ⁵ poises at a temperature of 190 ° C. and a shear rate of 1.00 sec ⁻¹ , and is described in JP-A-6-172620. This biodegradable plastic is biodegraded by the action of microorganisms (bacteria, fungi) in soil, compost, etc., and finally becomes carbon dioxide and water. Further, since the insertion fixing portion 1A has a strong mechanical strength, it has a high rigidity and the work of inserting it into the ground surface can be performed very easily. Moreover, since it is excellent in tensile strength, when the rod 1 is bent into a substantially V shape, sufficient locking strength can be obtained in the runner locking portion 1B of this bent portion. Furthermore, since the runner locking portion 1B has flexibility, there is no risk of damaging the runner P during mounting. Also, since it is highly resistant to moisture, it is possible to maintain a sufficient fixing force even when it is used during the rainy season, such as when growing strawberries.

Since the present invention is used by bending the rod 1 into a substantially V shape, it attracts runners P such as strawberries, melons, watermelons and pumpkins, as well as runners of other plants. It is also possible to do so.

[0015]

[Effect of device]

 The present invention achieves the original purpose by being configured as described above.

That is, according to the first aspect of the present invention, it is only necessary to bend the rod body 1 into a substantially V shape and insert it into the ground at the time of mounting. Moreover, it has become possible to biodegrade used attractants naturally without affecting plants.

Further, according to the second aspect, the insertion fixing portion 1A has a hardness such that the insertion fixing portion 1A can be easily inserted into the inside of the ground surface, and the decomposition can be accelerated.

Further, according to the third aspect, sufficient locking strength can be obtained in the runner locking portion 1B of the bent portion. Moreover, since the runner locking portion 1B has flexibility, the runner is not damaged when fixed. Moreover, it has excellent moisture resistance and can maintain a sufficient fixing force even when it is used during the rainy season. Further, the rod body 1 finally becomes carbon dioxide gas and water, and has no adverse effect on plants.

As described above, according to the present invention, the workability at the time of mounting is extremely good, the runner is not damaged at the time of fixing, and the used attracting tool can be naturally removed. It has various practically useful effects, such as no possibility of adversely affecting plants.
