Description

  The present invention relates to a plant growth management apparatus that is installed around the root side of a plant and that can manage growth while protecting the plant.

  In order to cultivate plants, it is necessary to pay attention to various points such as temperature and moisture management, weed removal and insect control. Conventionally, a management method has been known that stabilizes the ground temperature by preventing drought of the ground and preventing a sudden change in temperature by preventing the ground from drying by laying a straw or the like on the ground where plants are cultivated. ing. In addition, weeds need to be removed regularly. In approximation, a mower that cuts grass by rotating the blade at high speed with the power of an engine or the like is often used. There was a problem that the blade hits and cuts or damages the tree. Conventionally, techniques for protecting weeds near the roots of trees and the like and protecting trees and the like from the blades of mowers have been proposed. For example, in Patent Document 1, a hole 2 through which a root such as a tree can be inserted is provided in the center, and a flexible covering 1 that can cover the ground surface around the root is provided. A root weed growth prevention cover is disclosed, which is provided with a notch 3 for insertion leading to a central hole 2. The root weed growth prevention cover was designed to prevent the growth of weeds on the ground surface around the roots of trees and the like, thereby improving the efficiency of the use of the mower and protecting the roots of trees and the like. The reference numerals are those of Patent Document 1.

  As in the past, if you simply lay a cocoon or the like at the base of the plant, if the wind blows, the cocoon will scatter and the heat retention and water retention effects will not function. Etc. were necessary, and there was a problem that was complicated and heavy labor. Further, the weed growth prevention cover for the root of Patent Document 1 is formed so that there is almost no gap between the root side of the tree and the edge of the hole 1 in the center of the flexible covering 1 so that weeds do not grow. In addition, since the ground is covered, water does not go directly to the ground, so that there is a risk that plant growth may be hindered and water management becomes complicated. In particular, when plants are seedlings and seedlings, temperature and moisture conditions tend to affect growth, and if they are not managed, they tend to die.

  The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to keep moisture around the root side of the plant and prevent the growth of weeds. An object of the present invention is to provide a plant growth management device that can prevent the cutting and scratching of plants and manage the growth of plants that are also excellent in insect repellent effect.

  In order to solve the above-described problem, the present invention provides a through hole 12 that is sufficiently larger than the root side circumference size of the plant P at a substantially central position so as to penetrate the root side of the plant P and cover the ground GL around the plant P. The ground covering portion 14 is formed so as to form a case-like space 28 having upper and lower surfaces that are filled and held with the water retention material 26 around the root side of the plant P. The plant growth management apparatus 10 is characterized in that it includes a water-retaining material accommodating cylinder portion 16 that integrally rises upward from the edge of the through-hole 12 and is continuously provided.

  Moreover, the water retaining material accommodation cylinder part 16 is good also as being formed in the taper cylinder shape whose cross-sectional shape becomes small gradually toward an upper end side.

  Further, the ground covering portion 14 is formed by a plate-like member 18 provided with a through-hole 12 at a substantially central position, and a water-retaining material accommodation portion comprising a hollow cylinder (30) with respect to the edge of the through-hole 12 of the plate-like member 18. It is good also as having assembled the lower end side of 16 surrounding walls so that attachment and detachment were possible.

  Moreover, the ground covering part 14 and the water retaining material accommodation part 16 are good also as being comprised by connecting the several member 32a, 32b divided | segmented into the circumferential direction so that separation and connection are possible.

  Moreover, it is good also as having the fixing member (46) which fixes the ground covering part 14 to the ground GL.

  According to the plant growth management device of the present invention, a through-hole that is sufficiently larger than the root-side circumference size of the plant is provided at a substantially central position so as to penetrate the plant root side and spread so as to cover the ground around the plant. Integrated from the edge of the through hole of the ground covering part so as to form a case-like space that opens the upper and lower surfaces that are filled with water retaining material and held around the root side of the plant, around the formed ground covering part And a water retention material storage cylinder portion that is continuously provided in a row, so that water retention materials such as straw, rice husks, and hay are securely held around the plant, and the water retention material is blown by the wind. It can be reliably prevented from being washed away by rain or rain, and the moisture necessary for the plant can always be maintained to prevent drying. At the same time, the water-retaining material storage cylinder surrounds and protects the surroundings of the plant, preventing the blade of the mower from hitting the plant when weeding the weeds on the surrounding ground, and cutting or scratching the plant. Can be prevented. Furthermore, it can prevent insect pests from attaching to the plant as an insect barrier rising from the ground. Furthermore, since the ground covering part covers the ground, weeds can be prevented from growing on the ground around the plant. Moreover, the ground temperature can be stably maintained. As a result, the plant can be grown under favorable conditions while appropriately managing and protecting the plant, and can be practically used for growing seedlings and seedlings.

  In addition, the water-retaining material accommodation tube portion has a tapered tubular shape in which the cross-sectional shape gradually decreases toward the upper end side, so that the stability in the installed state is good and the water retention material accommodation tube portion Since the opening on the upper end side is narrow, the water retaining material or the like accommodated in the internal space is not easily blown off by strong wind or the like, and the water retaining material can be reliably retained in the space of the water retaining material accommodating cylinder. Further, since a plurality of the same shape can be stacked due to the taper shape, a place is not taken when storing and storing.

  The ground covering portion is formed of a plate-like member provided with a through hole at a substantially central position, and the lower end side of the peripheral wall of the water retaining material containing portion made of a hollow cylinder is attached to the through-hole edge of the plate-like member. By adopting a structure that is detachably assembled, the ground covering portion and the water retaining material accommodating portion are separate members, which are easy to manufacture, convenient to store, and convenient to carry. Moreover, the growth management can be performed under conditions suitable for the growth of the plant, the kind of the plant, and the like by freely combining the width of the ground covering portion and the height of the peripheral wall of the water retaining material accommodating portion.

  In addition, the ground covering part and the water retaining material accommodating part can be divided into a plurality of members divided in the circumferential direction and connected to be freely connected, so that the ground covering part and the water retaining material accommodating part can be divided so that the plant can be divided. It can be easily removed without damaging it. Furthermore, the removed growth management device can be used again, is economical, reduces agricultural waste, and is easy to use. Further, it is convenient to carry it by dividing it into a plurality of members.

  In addition, by having a structure having a fixing member that fixes the ground covering portion to the ground, for example, the growth management device itself can be reliably prevented from being displaced from a predetermined installation position or being beaten by a strong wind or the like, It is possible to prevent the water-retaining material such as the baskets that are housed from being scattered outside and the water-retaining material-containing cylinder portion from damaging the plant.

  Embodiments of the plant growth management device of the present invention will be described below with reference to the accompanying drawings. The plant growth management device of the present invention is installed on the root side of a plant when cultivating plants such as fruit trees, trees, vegetables, etc., and can perform growth management while protecting the plant and holding a water retention material. is there. 1 to 5 show an embodiment of a plant growth management apparatus according to the present invention. As shown in FIG. 1, in the present embodiment, the plant growth management device 10 includes a ground covering portion 14 provided with a through hole 12 and a water retaining material accommodating cylinder portion 16. In this embodiment, the plant P to which the plant growth management apparatus 10 is applied is applied to seedlings of fruit trees such as gummy, kumquat, and blueberry. The plant P is not limited to fruit trees, and can be widely used for growing crops such as vegetables, tobacco, and flowers, and other arbitrary plants.

  As shown in FIGS. 1, 2, and 3, the ground covering portion 14 is provided with a through-hole 12 that penetrates the root side of the plant P at a substantially central position, and the through-hole 12 penetrates the root side of the plant. It is a covering means that covers the ground GL around the plant P in a state. The ground covering part 14 prevents weeds from growing around the plant by covering the ground over a certain range. Further, the ground covering portion 14 also functions as a stable support portion that stably supports a water retaining material accommodating cylinder portion 16 described later on the ground. In the present embodiment, the ground covering portion 14 is composed of, for example, a plate-like member 18 having a circular shape in a plan view formed of a synthetic resin such as plastic, and is concentric and circularly penetrated at a substantially circular center position of the plate-like member 18. A hole 12 is formed. The ground covering portion 14 formed of the plate-like member 18 has a stepped portion 20 formed by integrally projecting a circular portion around the edge of the through hole 12 upward from the covering main body portion. That is, the stepped portion 20 protrudes inward in the horizontal direction in an L-shaped cross section from the upper end of the short cylindrical peripheral wall 22 having a diameter slightly larger than the diameter of the through hole 12 and rising in a circular short cylindrical shape. And a stepped edge wall 24 that forms the edge of the through hole 12. The diameter of the through-hole 12 is formed sufficiently larger than the root-side circumference size of the plant P, and is sufficient between the edge of the through-hole 12 and the root side of the plant P passing through the through-hole 12. A margin (gap) is formed. The size and shape of the ground covering portion 14 and the through hole 12 may be arbitrary. For example, the ground covering portion 14 and the through hole 12 are not limited to a circular shape, and may be any other shape such as an elliptical shape, a rectangular shape, or a hexagonal shape.

  As shown in FIGS. 1, 2, and 4, the water-retaining material accommodating cylinder 16 is filled with and holds a water-retaining material 26 around the root side of the plant P that has passed through the through-hole 12 of the ground covering portion 14. The holding means for the water retaining material is integrally provided so as to rise upward from the edge of the through hole 12 of the ground covering portion 14 so as to form a case-shaped space 28 having an open bottom surface. In this embodiment, the water retention material accommodation cylinder part 16 consists of a hollow cylinder formed with synthetic resins, such as a plastics, for example. As shown in FIGS. 4 and 5, the water retaining material accommodating cylinder portion 16 is formed of, for example, a member different from the ground covering portion 14 made of the plate-like member 18, and the through-hole 12 of the plate-like member 18 is formed. The lower end side of the hollow cylindrical body is engaged with the edge and is integrally assembled so as to be detachable. Specifically, for example, the water-retaining material accommodating cylinder portion 16 has a circular cross-sectional shape, is gradually formed to be linearly smaller from the lower end side toward the upper end side, and the outer contour shape is a truncated cone shape. It is provided with the hollow taper cylinder 30 which becomes. The tapered cylindrical body 30 is open on both upper and lower surfaces, and a peripheral wall is provided at a predetermined height so as to form a case-shaped space 28 for holding the water retaining material 26 inside the hollow cylinder. Accordingly, the tapered cylindrical body 30 is continuously surrounded by the peripheral wall around the root side of the plant by forming the peripheral wall at a predetermined height and rising to a certain extent from the edge of the through hole 12 of the ground covering portion 14. A case-like space 28 is formed. The size of the opening on the upper end side of the tapered cylinder 30 is set to a sufficiently large diameter. That is, in any cross section of the peripheral wall of the tapered cylindrical body 30, the inner wall peripheral size is formed sufficiently larger than the root side peripheral size of the plant P, and the root side of the plant P passing through the through hole is A sufficient margin (gap) is formed between them. A gap formed between the inner wall of the tapered cylindrical body 30 and the root side of the plant P is filled with the water retaining material 26 to form a case-like space 28 in which the filled state can be maintained. It can be said that the case-like space 28 is realized by a tapered cylindrical body 30 having a cross-sectional shape larger than the root-side circumference size of the plant and formed by a peripheral wall having a height for containing the water retaining material. The tapered cylindrical body 30 is formed, for example, with a diameter slightly lower than the through hole 12 of the plate-like member 18 and slightly smaller than the inner diameter of the short cylindrical peripheral wall 22. In a state where the lower end portion of the tapered cylindrical body 30 is engaged with the plate-like member 18, the lower end portion of the tapered cylindrical body 30 is accommodated inside the stepped portion 20 of the plate-like member and is prevented from coming off from the through hole 12. Is engaged in a fitting state in a restricted state. Further, as shown in FIG. 2, the gradient of the peripheral wall of the tapered cylindrical body 30 causes the lower end side of the tapered cylindrical body 30 and the plate-like member 18 to be integrally engaged, and the lower end edge and the plate of the tapered cylindrical body 30. In a state where the lower surface of the cylindrical member 18 is in contact with the ground GL, the circumferential wall of the tapered cylindrical body 30 is set at an inclination angle so that a gap is not formed by contacting the edge of the through hole 12 of the plate-shaped member 18, In the engaged state, the peripheral wall of the tapered cylindrical body 30 is provided so as to rise from the edge of the through hole 12 of the plate-like member 18.

  As shown in FIG. 5, when assembling the water-holding material accommodation tube portion 16 composed of the tapered tubular body 30 with the ground covering portion 14 composed of the plate-like member 18, for example, the plant is formed on the peripheral wall of the water retention material accommodation tube portion 16. The ground covering portion 14 is inserted into the loosely fitting shape from the upper side of the water retaining material accommodating cylinder portion 16 through the through hole 12 in a state of being arranged at a predetermined position so as to surround. Since the upper end of the water retaining material accommodating cylinder portion 16 is formed small, the alignment between the upper end of the water retaining material accommodating cylinder portion 16 and the through hole 12 of the ground covering portion 14 may be rough to some extent. Further, when the ground covering portion 14 is lowered downward along the peripheral wall of the water retaining material accommodation tube portion 16, the water retaining material accommodation tube portion 16 is formed at the edge of the through hole 12 with the lower surface of the ground covering portion 14 reaching the ground. The lower end side of the water retaining material accommodating cylinder portion 16 is fitted into the through hole 12 of the ground covering portion 14 so as to be positioned and assembled at a position slightly above the lower end. In the state in which the ground covering portion 14 and the water retaining material accommodating cylinder portion 16 are assembled, as shown in FIGS. 1 and 2, for example, the ground covering portion 14 continues in the circumferential direction from the lower end side of the water retaining material accommodating cylindrical portion 16. In addition, it protrudes in a flange shape toward the outside, and is formed into a hat-like shape (hat shape) as a whole. In addition, the water retention material accommodation cylinder part 16 is not restricted to a taper cylinder shape, For example, you may form with the cylindrical body of the same system from a lower end to an upper end. Further, the water-retaining material accommodating cylinder portion 16 is not limited to a circular cross section depending on the shape of the through hole 12, and may be any other shape such as an elliptical shape, a square shape, a hexagonal shape, and the like. Moreover, the height of the surrounding wall of the water-retaining material accommodation cylinder part 16 may be arbitrary, and a plurality of cylinders having different heights may be prepared according to the growth stage or type of the plant, and these may be freely exchanged. .

  As the water-retaining material 26 filled in the water-retaining material accommodation tube portion 16, for example, natural materials such as straw, rice husk, and dried grass are used. Basically, the water retentive material 26 may be any water retentive material, such as synthetic resin fiber or sponge material, as long as the water retentive material 26 is water retentive and moisturized to prevent the plant from drying. . However, straw, rice husks, dried grass, etc. can obtain a heat retaining function to maintain the temperature of the ground around the plant, and also decompose as time passes and function as a plant fertilizer. It is advantageous in that it can be effectively assisted and does not require separate disposal. It should be noted that not only the water retention material 26 but also plant fertilizer may be placed in the case-shaped space 28 of the water retention material accommodating cylinder 16.

  Next, the operation of the plant growth management apparatus 10 according to the present embodiment will be described. As shown in FIGS. 1 and 2, for example, a plant growth management device 10 is installed around a seedling of a plant P such as a gummy planted on the ground GL. As shown in FIG. 5, the installation work is performed by placing the tapered cylinder 30 through the lower end opening so that the peripheral wall surrounds the periphery of the plant and penetrating the plate-like member 18 from the upper end side of the tapered cylinder 30. It only needs to be fitted through the hole 12, and can be easily installed. Then, the water-retaining material 26 such as straw or rice husk is filled in the case-shaped space 28 of the water-retaining material accommodating cylinder 16, and the water retentive material 26 is held around the root side of the plant P. For example, even when a strong wind blows or rains, the water retaining material accommodating cylinder 16 can reliably protect the water retaining material from being scattered by the wind or being washed away by the rain. A good growth environment can be maintained by preventing reduction or disappearance from the surroundings of the plant. Furthermore, since the ground covering portion 14 covers the ground around the plant P, weeds are difficult to grow. In addition, when weeds that grow on the ground outside the ground covering portion 14 are weeded by a mower or the like, the water retaining material accommodating cylinder portion 16 prevents the blade of the mower or the like from cutting or damaging the plant. Thus, the plant P can be reliably protected. Moreover, it is possible to prevent pests and the like from approaching the plant by the water-retaining material accommodation tube portion 16. Therefore, management and protection of the root side of the plant can be performed, and the plant can be grown well. For example, in the case of a vegetable or the like having a relatively short cultivation period rather than a plant such as a fruit tree having a long cultivation period, the plant growth management device 10 can be collected and reused after the vegetables are harvested. Moreover, in the said embodiment, although the ground covering part 14 and the water retention material accommodation cylinder part 16 of the plant growth management apparatus 10 were formed with synthetic resins, such as plastic, they are formed with biodegradable materials, such as paper, for example. Also good. When the plant growth management device 10 is formed of a degradable material, it is eventually decomposed over the years to return to the soil and become a fertilizer for the plant. Therefore, the plant growth environment is good and there is no need to collect it. At the same time, no garbage is generated.

  Next, a plant growth management apparatus 10-2 according to a second embodiment of the present invention will be described with reference to FIGS. The same configurations and the same members as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted. In the second embodiment, for example, the ground covering portion 14 and the water retaining material accommodation tube portion 16 are integrated as a single molded product, unlike the above-described embodiment in which separate separable members are assembled together. Is formed. In the present embodiment, the ground covering portion 14 is formed in a circular plate shape as a whole, and the lower end of the tapered cylindrical water-retaining material accommodating tube portion 16 is completely fixed to the edge of the through hole 12. Also in the present embodiment, the same effects as those of the above-described embodiment, such as retention of the water retaining material around the root of the plant, prevention of weeds, protection of the plant from the mower, and insect repellent effect, can be achieved. Moreover, since the plant growth management apparatus 10 can be handled as a single member, the number of work processes during installation and removal is small, and parts management and the like are easy to perform.

  Next, the plant growth management apparatus 10-3 according to the third embodiment of the present invention will be described with reference to FIG. 8, but the same members as those in the above embodiment will be denoted by the same reference numerals and detailed description thereof will be omitted. To do. As shown in FIG. 8, in the present embodiment, the ground covering portion 14 and the water retaining material accommodation portion 16 are configured by separately connecting a plurality of members 32 a and 32 b divided in the circumferential direction. In FIG. 8, the plant growth management device 10 is cut at the diameter position of the ground covering portion 14 and the water retaining material containing cylinder portion 16 that are circular in plan view, for example, and is divided into two in the circumferential direction. The 1st, 2nd division member 32a, 32b which comprises the coating | coated part 14 and the water retention material accommodation cylinder part 16, and the connection / separation apparatus which connects those 1st, 2nd division members 32a, 32b so that connection and isolation | separation are possible. 34. The first and second divided members 32a and 32b are respectively covered with the covering elements 14a and 14b constituting the ground covering part 14 and the cylindrical elements 16a and 16b constituting the water-retaining material accommodating cylindrical part 16 in a connected state in the circumferential direction. And are integrally fixed. That is, the ground covering portion 14 has a circular plate shape when connected in the circumferential direction, and is divided into semicircular plate-shaped covering portion elements 14a and 14b that form a circular through hole 12 at the center position inside. . At the same time, the water retaining material accommodating cylinder 16 is divided into semicircular tapered cylindrical cylinder elements 16a and 16b that form a hollow tapered cylinder having a circular cross section in the circumferentially connected state. The connecting device 34 includes, for example, a U-shaped connecting member 36 and a receiving hole 38 provided near the connecting edge of the plate-like main body portion of the covering element 14a, 14b and into which the connecting member 36 is inserted. By inserting the connecting member 36 into the receiving hole 38 in a state where the first and second divided members 32a and 32b are combined with each other, the U-shaped connecting member 36 straddles the divided members 32a and 32b. Removably connected. In addition, the division | segmentation to the circumferential direction of the plant growth management apparatus 10 is not restricted to 2 division structure, You may comprise in 3 divisions or more. The connecting / separating structure 34 for connecting the split members may be any other separable / connectable connection, such as a connection configuration using male and female button members, a connection configuration using male / female fitting, a connection configuration using pins, bolts and nuts, etc. It may be a structure. In addition, the connection structure may be a structure in which the cylinder elements 16a and 16b are connected to each other. Also in the present embodiment, the same effects as those of the above-described embodiment, such as retention of the water retaining material around the root side of the plant, prevention of weeds, protection of the plant from the mower, insect repellent effect, and the like can be achieved. Moreover, in this embodiment, since the ground covering part 14 and the water retention material accommodation cylinder part 16 can be divided | segmented into the circumferential direction, it can isolate | separate as needed and can make a plant growth management apparatus remove | separate easily from the circumference | surroundings of the plant P. At the same time, the plant growth management device can be reused again.

  Next, a fourth embodiment of the plant growth management apparatus according to this embodiment will be described with reference to FIG. The same members as those in the above embodiment are denoted by the same reference numerals and detailed description thereof is omitted. As shown in FIG. 9, in the fourth embodiment, similarly to the third embodiment, the plant growth management device 10 includes the first and second divided members 32a and 32b and the first and second divided members. The structure includes a connecting / separating device 34 that connects the members 32a and 32b in a connectable / separable manner, but the structure of the connecting / separating device 34 is different. For example, at the connecting end portion of the covering element 14a, 14b, there are a protruding piece 40 protruding in the circumferential direction on one side and a receiving recess 42 recessed on the other side and receiving the protruding piece 40 in a fitting manner. Is provided.
