Description

  The present invention relates to a plant protection fence for preventing damage caused by surrounding a plant on the ground with a fence to protect it from animal damage.

When planting trees such as cedar, camellia and fruit trees in mountainous areas with many wild animals, and growing vegetables and other useful herbaceous plants for commercial purposes, they are damaged by animals such as deer, moths, moths and moths. There is a case.
Insufficiency is particularly common in plants at relatively young times such as young trees, or trees whose bark is food-like such as deer.

  In order to prevent the feeding damage of the growing plants by animals living in the outdoors, measures are taken to prevent harmful animals from invading the plant cultivation site by installing a defense fence with nets and fences around forests and fields. Generally adopted.

  In addition, to protect individual seedlings, not the entire plant cultivation site, a method of driving a pile around the protected plant and attaching a resin sheet or net to it with a wire or string is known. Yes.

  Further, as a technique for not driving a pile around a tree, an anti-corrosion device is known in which a biodegradable synthetic resin net is directly wound around and fixed to the outer peripheral surface of a trunk (Patent Document 1).

  Furthermore, as shown in FIG. 3, a synthetic fiber cloth 4 is formed into a cylindrical shape having a height of about 100 to 180 cm, and this is connected to a column 5 fixed to the ground G to protect the young tree A. A cylindrical thing is also known (patent document 2).

  However, in the above-described conventional technology, it is not easy to securely fix a net or a cylindrical object for protecting a young tree to a tree or the ground, or to install against a pest of a harmful animal. For example, the entire circumference surrounding the tree cannot be supported evenly, the fixed support force is weak, and if using a net or cloth, harmful animals can easily invade the boundary with the ground, making it easy to install There was no thing that could prevent the damage.

  In particular, conventional tree-covering cylindrical objects have a drawback in that the pillars fixed to the ground and the cylindrical objects are not sufficiently integrated, and are easily invaded by small pests.

  Therefore, the problem of the present invention is to solve the above-mentioned problems, and can easily and reliably fix the plant such as trees to the ground, and the boundary part with the ground is also densely configured to prevent the harmful animals. It is a plant protection fence that is excellent in invasion prevention and has an effect of reliably preventing food damage by installation work as simple as possible.

  In order to solve the above-mentioned problems, in the present invention, a required number of fence bars that surround a plant to be protected on the ground are provided, and the pile bars that are longer than the bars are formed into the plurality of fence bars. It was a plant protection fence for preventing damage caused by knitting a string with objects.

  The above-mentioned plant protection fence for preventing damage is composed of a fence-like bar and a pile-like bar made of string-like material, so that the fence and the pile are constructed integrally from the beginning. Convenient for storage and transportation. In addition, in order to form a cylindrical protection area around the young vegetation tree, when the cage-like plant protection fence for preventing damage to food is arranged in an appropriate fence shape, it is knitted with a string-like object integrally with the fence-like rod-like object. A protective fence can be installed simply by driving the end of a pile rod that is slidably stopped into the ground.

  Since the pile rods that are longer than the fence rods are knitted in a state that can be slid in the longitudinal direction independently of the fence rods, What is necessary is just to press-fit in the ground to the depth which can fix the lower part, and you may press-fit in the ground using a civil engineering machine (hydraulic drive machines, such as a shovel car). Thus, when the bar-like object for the fence is inserted into the ground and firmly fixed, the annular protective fence surrounding the vegetation tree can be securely fixed and installed.

  Such protection fences are used for shape retention when connecting the ends of the protection fences or by connecting both ends when the ends of the string-like objects are left unused for knitting. Available for fastening. That is, when the string-like object is extended from both ends of the protection fence and is provided in a length that becomes a strap, and the protection fence is bent and both ends are brought close together, the opposite straps can be combined to form an annular shape. It is also possible to extend the length of the fence by connecting another similar protective fence.

  Plant protection fences for food damage prevention that are installed and used in this way, especially by constructing the rods for fences and rods for piles with rods that are biodegradable or oxidatively degradable in the natural environment, When it grows and is harvested or felled, it becomes part of the soil and integrates with nature, so that it does not place a burden on the environment, and it can be omitted in the work of collection and treatment.

  As described above, the present invention is provided with a required number of fence rods that surround the plant to be protected on the ground, and the pile rods longer than the rods are stringed together with the plurality of fence rods. Since it was knitted in a bowl shape, it can be installed only by driving and fixing the pile rods to the ground when placing a bowl-like plant protection fence around the seedlings The protective fence for preventing damage to the ground can be easily and reliably fixed to the ground by surrounding the trees such as trees to be protected, and the boundary between the ground and the ground is also configured without any gaps. It has the advantage of being a plant protection fence for preventing damage that can be reliably prevented by installation work as easily as possible.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1 and FIG. 2, the embodiment has a large number of fence-like rods 1 made of trimmed cocoons with a certain length, etc. Pile rods 2 made of steel or the like are used in a mixture, and one end of these two types of rods is aligned, and the pile rods 2 are arranged at substantially equal intervals with one end facing downward. Is a plant protection fence for preventing damage caused by a string-like object 3 so that the upper part of the nose protrudes upward from a number of bar-like objects 1 for a fence.

  The bar 1 for a fence is formed of a material having a strength that is not destroyed even when an animal that damages a plant contacts with a normal eating behavior. As a specific example of the bar 1 for a fence, when a deer or the like is used as an animal subject to damage, it is preferable to employ a hard natural material such as a bamboo shoot or bamboo. May be made of synthetic resin or rubber-like elastic material.

  In particular, it is preferable that it can withstand the required years to prevent food damage and then be used by natural microorganisms or be degraded to the molecular level by air oxidation, degradation by ultraviolet rays, or the like.

  As the material for the rod 1 for a fence having both durability and decomposability, for example, a perennial grass of the family Gramineae that has been harvested from a vine that grows naturally on the waterside can be used. Other materials for the rod 1 for fences include plant bodies such as bamboo shoots, bamboos divided into appropriate widths, reeds (grooms), gama (cage), gogyo (forms), and biodegradable resins (polylactic acid). Synthetic resins such as plastic resins, etc., or thin wood cut into rods or other wood-based molded products such as wood or pulp processed products, or the surface of these or the above-mentioned rod-shaped materials are coated with synthetic resins (biodegradable resins, etc.) It is also possible to employ a rod-shaped object that has been made.

  It is also preferable to use such a rod 1 for a fence soaked with a repellent component corresponding to a harmful animal that prevents food damage.

  On the other hand, the pile rod-like object 2 requires mechanical strength (rigidity) to support the above-described fence rod-like object 1 and is oxidized (ie, rusted) and integrated with soil components. It is preferable to employ a metal material that can be corroded. Incidentally, in the case of iron materials, the degree of corrosion resistance can be adjusted by adjusting the amount of nickel component.

  Moreover, the composite material which increased the intensity | strength of the raw material similar to the rod 1 for fences mentioned above by making a metal material into a pipe shape can also be employ | adopted. Furthermore, a composite material of a metal material and a synthetic resin such as a biodegradable resin can be employed to adjust strength and degradability.

  The string-like object 3 used for knitting in the present invention is a combination of a required number of fence-like bars 1 that surround a plant to be protected on the ground and a pile-shaped pole 2 that is arranged with a gap therebetween. For example, natural fibers such as cotton yarn and hemp yarn, synthetic fiber yarns and thin ropes, belt-like (tape-like) cloths, metal wires, piano wires, fishing lines and the like can also be used. It is preferable that such a string-like material 3 is also biodegradable.

  A large number (about 50) of reeds are cut into a length of 1.2 m, and four columnar iron bars with a length of 1.5 m and a diameter of 8 mm are prepared. A plant protection fence with a width of 60 cm having a full width of 60 cm in the form shown in FIGS. 1 and 2 was produced in the manner of knitting a rivet while aligning one end of the heel and the iron bar while braiding one iron bar at intervals.

  At that time, the braided hemp rope was left as a strap 3a that was not used for knitting by a length of about 10 cm in the width direction of the fence.

  When using the plant protection fence for preventing food damage prepared as described above, as shown in FIG. The upper end of the iron bar is struck in the direction of the arrow with a hammer and driven into the soil as shown by the chain line, and the upper end of the bar and the upper end of the iron bar are fixed at the same height, and then the opposite hemp rope The straps 3a are joined together to eliminate the gaps at both ends of the protective fence.

  In this way, when installing a plant protection fence for preventing damage, it is simple without carrying piles or fences separately to the site, and can be easily and reliably fixed to the ground using a pile rod. Since the boundary with the ground can be installed without any gaps, a protective fence was installed that was excellent in preventing the invasion of pests such as deer, cormorants, and spiders.

  In addition, after the seedlings were grown, cocoons and iron bars were decomposed by microorganisms, or oxidized to generate rust, which progressed and decayed, gradually becoming soiled.
