DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant cultivation unit and a construction method for plant cultivation using the same.

[0002]

2. Description of the Related Art Conventionally, various construction methods for plant cultivation using a container-shaped planter have been adopted (for example, Japanese Utility Model Application Laid-Open No.
457, JP-A-4-99414, JP-A-8-379
No. 64), as a conventional problem, after the planter was installed, the supply of soil and the leveling were very troublesome.

[0003] The applicant of the present invention has previously invented and applied for a ground covering plant cultivation unit using a non-biodegradable bag-like body (Japanese Patent Application Laid-Open No. 8-149905). Left. In other words, since soil bags are non-biodegradable and retain their shape over a long period of time, soil microorganisms can enter the inside of the bags, but soil organisms cannot enter and the soil ecological balance is maintained. No effective renewal of soil.

[0004] Since only the water retention of the soil itself is performed, the amount of water retention decreases as the soil becomes thinner. Non-biodegradable bags do not fit well with the roots of plants when cultivating by laying ground cover plants, such as grass, directly on top of the bags. Therefore, in the present invention, it is an object of the present invention to provide a plant cultivation unit that solves the above-mentioned problems and facilitates the supply of soil to a planter, and a plant cultivation construction method using the same.

[0005]

Means for Solving the Problems In order to solve the above-mentioned conventional problems, as a result of various studies, the plant cultivation unit according to the present invention obtained as a part of the present invention has a drainage part. And a combination of a container-shaped planter having a portion and a bag made of a natural fiber-based material containing soil for laying in a blunter.

According to the plant cultivation unit of the first aspect, the soil housed in the bag-shaped body is formed in a bag with an appropriate amount of soil considering the volume of the planter in advance. It can be used simply by laying it in the planter while it is stored, and the bag is biodegraded by moistening the bag by watering, soil organisms can enter the bag, and as a soil with good ecological balance It is convenient to use.

[0007] The drainage part provided in a part of the planter may be, as described in claim 2, a part of the planter having a lower side wall part and a concave part inside and outside the side wall, and a bottom part and a side wall. It is characterized in that it is formed so as to communicate sequentially with the notch formed at the outer surface boundary with the part and constitutes the drainage part, so that the soil contained in the planter is lost at the time of drainage. It can be used as a small drainage part, which is convenient.

Further, when the planter is formed of a synthetic resin foam as described in claim 3, not only the moldability is easy and the production is easy, but also the handleability and the light weight, the heat insulation and the like are improved. This is preferable in terms of performance. Then, as for the construction method for plant cultivation using the plant cultivation unit as described above, as described in claim 4, after installing one or more container-shaped planters having a drainage part in the construction place Then, a bag made of a natural fiber material containing the soil is housed in a planter, and then water is sprayed from the surface of the bag, the bag is moistened with water, and then planted by leveling. It is characterized by being constructed in a cultivable state.

According to the construction method for plant cultivation according to the fourth aspect, after the planter is installed at the construction site, it is simply stored in the planter in the form of a bag containing soil and sprinkled.
Since the bag-like body can be moistened and brought into the soil-contained state, and the plant can be cultivated immediately with only a little leveling, it is possible to shift to lawn laying according to claim 5 or sowing work according to claim 6. Things.

[0010]

Next, a preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view, and FIG. 2 is a perspective view at the time of construction for plant cultivation. In the figure, P is a container-shaped planter having a drainage portion 10 in a part thereof. It is formed of a resin foam. A shows a bag made of a natural fiber material, in which soil S to be laid in the planter P is stored. A unit for plant cultivation is constituted by a combination of the planter P and the bag-shaped body A.

The container-shaped planter P will be described in further detail. The container-shaped planter P is formed into a rectangular container as shown in the figure, and the side wall portion 1 and the bottom plate 2 are integrally formed. A lower portion 11, concave portions 12, 12 ′ formed on the inner and outer sides of the side wall portion 1, and a notched portion 1 formed on an outer surface boundary between the bottom portion 2 and the side wall portion 1.
3 are formed so as to communicate sequentially in the order of the inner concave portion 12, the lower formed portion 11, the outer concave portion 12 ', and the notched portion 13, so that the inner side of the planter P moves outward from the inner side. This is configured as a drainage section 10 of FIG. In the figure, reference numeral 20 denotes a groove-shaped steel joint that connects the planters P, P, and the joint 20 is formed such that the lower end thereof is higher than the bottom plate 2 of the planter P ( (See FIG. 1).

On the other hand, a bag A made of a natural fiber material is
For example, it is formed of cotton and wool, and when sprayed on the bag-shaped body A, it is moistened, the bag-shaped body is biodegraded, and soil organisms easily enter the inside of the bag, Improve the ecological balance of the soil. The container-shaped planter P described above;
In order to perform plant cultivation construction using the bag-shaped body A containing the soil S, first, a place where the container-shaped planter P is installed is determined, and one or more of the container-shaped planters P are placed. 2 shows an example in which four container-shaped planters P, P,. The container-shaped planters P, P are stably installed in a state of being directly connected to each other with the joint 20 exemplified above. Next, when the bag-shaped body A is inserted into each of the container-shaped planters P and watering is performed from above, the bag-shaped body A is wetted and then biodegraded. Outflow can be prevented. After that, the soil S is appropriately grounded and constructed so as to be capable of plant cultivation, a lawn is laid on the leveled ground, a seeding operation is performed, and the ground is re-leveled.

Excess water from the sprinkler falls from the inner recess 12 of the container-shaped planter P, through the lower portion 11 of the side wall 1 and from the outer recess 12 'to form a container. Even in the part where the planters P, P are juxtaposed so as to be adjacent to each other, the bottom part 2 and the side wall part 1 extend from the recess 12 '.
Can be drained through the notch 13 at the outer boundary with the above.

As the soil S, an inorganic material such as pearlite is used because it is easily corroded when an organic substance is added.
Then, in the case of plant cultivation construction that requires a large amount (deep) of soil S, as shown in FIG. 3, a frame 50 having a stackable stepped portion 5 is placed on a container-shaped planter P. If combined, it can be used as a planter with an increased internal volume. As the frame 50, a synthetic resin foam is a preferable material from the viewpoint of lightness and moldability as well as the container-shaped planter.

As the shape of the bag-like body A, any shape can be used as long as it can be inserted into the container-like planter P. The following is a comparison with the synthetic fibers used in the above-mentioned “Japanese Patent Application Laid-Open No. 8-149905” using the non-degradable nonwoven fabric of the previous application. The reason for choosing natural fibers is that biodegradability makes it possible for soil organisms to invade.

[0016] The roots of the plant are familiar. Easy to secure moisture. For example, it is easy to compare specific physical property values, but as shown below, cutting elongation (%) Cotton 6 to 10 Wool 20 to 40, polyester 42 water content (%) Cotton (at 5% humidity) 17 Wool (at 20% humidity) 16 vs. Polyester (at 8% humidity)
0.4 Wet swelling rate (%) Cotton 20-26 Wool 22-26 Acrylic 5.1 Vinylon N4.3, etc. Fibers decompose as expansion proceeds indefinitely, but organic fibers using water as a plasticizer Of course, the decomposition speeds up.

[0017] Even before the decomposition, the natural fiber has a lower elongation at break, so that it is quickly broken by an external pressure. Therefore, the invasion speed of soil organisms is so high, and the invasion of plant roots is performed quickly. In terms of the water content, the synthetic fiber has water repellency first, and therefore contains almost no water and has a value two digits lower than that of the natural fiber. Therefore, natural fibers are also desirable in securing moisture for plants.

Moreover, the bag-like body made of natural fibers is well-adapted to the roots of the plant, so that it grows well. For the above reasons, it can be said that a bag for soil made of natural fibers is suitable as a material of the present invention.

[0019]

According to the plant cultivation unit of the present invention as described above, a bag-like body formed by soil storage combined with a container-shaped planter having a drainage part is formed from a natural fiber-based material. Because of this, it has good familiarity with the roots of the plant, so good growth can be expected. And the handling before insertion into the container-shaped planter is different from mere soil, it is easy to handle because the soil is not scattered by handling the bag-like body, it is easy to handle, and the insertion work into the planter is convenient, and after insertion Simply spraying water from the top of the bag-like body wets the natural fiber, and after wetting, it is easily biodegradable, soil organisms can enter the inside of the bag, and the ecological balance in the soil is improved.
In addition, even after the biodegradation, it is located in the container-shaped planter, so that the outflow of soil can be suppressed.

Further, when planting an undercover plant or the like, the water in the lower part of the soil (reservoir part) is moved to the upper part of the bag through the natural fiber bag, so that the water can be effectively retained in the upper part, and the upper part of the soil tends to be dry. Can be prevented and withering due to drying in the early stage of planting can be prevented. Furthermore, it is a convenient plant cultivation unit in that the soil can be exposed and the ground can be leveled.

[0021] Furthermore, the above-mentioned plant cultivation unit can be used for plant cultivation, which is very accurate and quick, and is widely used for various types of plant cultivation, and has achieved good results. .
