Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention provides a molding block in which a plant can be planted and cultivated freely in a cultivation container.
The present invention relates to a plant cultivation method for planting and growing a plant in the molding block, and a plant cultivation tool.

[0002]

2. Description of the Related Art Plant seedlings such as flowers and vegetables are bred in small shape containers made of synthetic resin, and the grown plants are cultivated by planting them in a larger cultivating container (for example, a flowerpot). . In addition, cultivating farmers and horticulturists grow plant seedlings in the small-sized synthetic resin shape-retaining container and sell the plants while planting them, and the buyer of seedlings has a larger cultivation container or Alternatively, the plant is replanted in the soil for cultivation.
A concrete example of this type of plant cultivation method will be described. As shown in FIG. 13, soil 2 is placed in a shape retention container 20a made of synthetic resin.
Using the seedling cultivation tool 20 filled with 0b (see FIG. 13 (a)), the cultivation soil P1 is filled with the soil 21 in advance, and a depression is formed in the center thereof (FIG. 13 (c)).
(See FIG. 13), while the shape-retaining container 20a is removed from the seedling cultivation tool 20 (see FIG. 13B), the soil 20b is carefully filled so as not to be collapsed, and the soil is buried in the depressions. Was adopted to grow the seedlings (Fig. 13 (d))
reference). In this type of plant cultivating tool, as described above, the soil material 21 is changed from the seedling cultivating tool 20 in the cultivating container P1 to the shape retaining container 20.
It is filled in the gap between the lump of soil 20b from which a has been removed (see FIG. 13D). That is, the seedling cultivation tool 20 has a shape when the soil 20b is put in the shape-retaining container 20a made of a synthetic resin, but at the time of planting, the shape-retaining container 2 is used.
Since 0a is removed, it is simply a lump of soil 20b, and if it is watered after planting, it will be integrated with the soil 21 in the cultivation container P1 without any gap. Furthermore, according to the above method, the skill level of the cultivation technique influences the quality of plant growth in replanting and soil preparation. Moreover, it is difficult to always obtain a constant cultivation environment.

[0003]

According to the above-mentioned conventional plant cultivation method and plant cultivation tool, as described above, the seedling cultivation tool has soil in a shape-retaining container made of synthetic resin. Although it shows a molded body in the state, the shape retaining container is removed when planting, so if it is just a lump of soil, if it is watered after planting, it will be integrated with the soil in the cultivation container without a gap. In addition, watering reduces the gap between soil particles and tightens them. On the other hand, in order for the planted plant to grow, it is preferable that the roots are evenly spread in the soil so that water and nutrients can be absorbed evenly. And it also needs a proper breathability. Therefore, in the conventional case, when soil is tightened, it becomes difficult for roots to enter the soil particle gap, and the air permeability of soil is also reduced. As a result, there are problems that the growth of the roots is insufficient and that the way the roots spread in the soil is biased. In any case, such problems tend to hinder the sufficient growth of plants.

Therefore, an object of the present invention is to provide a plant cultivation method and a plant cultivation tool which can be easily and stably carried out without requiring any skill in plant cultivation.

It comprises a plurality of molding blocks 1 in which plants G can be planted and cultivated freely, and a cultivation container P1 for accommodating them.

As shown in FIG. 3, the cultivation container P1 is
It is formed in a bottomed tubular shape, and a drain hole 2a for sweeping water is formed in the central portion of the bottom portion 2. The height of the cylindrical portion 3 of the peripheral portion is set to be larger than the height of the molding block 1. Therefore, in the state where each molding block 1 is installed on the bottom portion 2, the upper end of the molding block 1 is located lower than the upper end of the tubular portion 3, and overflows from the cultivation container P1 when watering. It is structured to be difficult. The cultivation container P1 is not particularly limited, but for example, synthetic resin, ceramics, wood,
It can be formed of a material such as stone or metal, and corresponds to a so-called commercially available flower pot or the like.

The molding block 1 is a mixture of organic soil material such as bark compost, peat moss, and mulch.
For example, artificial soil that is integrally formed by consolidation molding with hydrophilic urethane prepolymer obtained by reacting polyether polyol (polyol component) and polyisocyanate (isocyanate component), and is formed in a porous and elastic state. I am doing it. For example, these artificial soils are designed so that organic soil materials such as bark compost, peat moss, and mulch are molded and held in an elastic state by utilizing the polyurethane foam reaction, and the porosity is 90% or more. (JP-A-51-27545, JP-B-56-18165, JP-A-58-198516,
See USP 4034508, USP 4175355).
The manufacturing method is not limited to these, and the porosity can be appropriately changed by the manufacturing method. Cultivation container P1
When it is placed inside, since some deformation can be tolerated, it can be installed in a state in which it is well-adapted to the shape of the cultivation container P1, but the water itself does not compact itself even if it is watered. Does not hinder the growth of. Therefore, the roots of the plant G planted are allowed to extend along the porosity of the forming block, and can evenly spread throughout the inside of the forming block to absorb water and nutrients. In this embodiment, bark compost, peat moss, and organic soil materials such as mulch are mixed and molded with a binder of a polymer resin such as polyurethane. However, in the present invention, not limited to these, as long as it is molded into a block, rock wool, or latex resin, ethylene resin, propylene resin, styrene resin, urethane resin, phenol resin, cellulose acetate, etc. It is possible to use a floor material for plant cultivation composed of various foamed resin materials obtained by foaming, and it is also possible to use a commercially available molded soil that is molded into a block shape using these materials. In addition, compression molding of plant soil material such as peat moss, fibrous moldings such as cellulose, ceramics, inorganic foam such as foam wrought stone, and various soils normally used as soil are solidified with resin binders and adhesives. It can also be molded and used. The porous condition which is preferable as the material for the molded block can be selected in consideration of the air permeability, water absorption, drainage property and water retention which are considered preferable for plant growth. The shape of the molding block 1 is not particularly limited, but in this example, two types are prepared depending on the difference in shape.

As shown in FIG. 5, the first molding block 1A has a rectangular upper end surface, a circular lower end surface, and a truncated cone shape with a smaller diameter toward the lower end. In the embodiment, the set dimension of the first molding block 1A is approximately 2 cm to 1 in outer diameter when used in home gardening.
It is preferably 5 cm and the height is about 5 cm to 15 cm. Then, a hole 1a into which a plant G can be planted is formed in the central portion of the upper end surface. In this hole 1a, the plant G
It is also possible to plant directly, but the soil 4 having a shape that fits into the hole is formed in advance, and the plant G is planted with this soil 4.
It is also possible to plant the seedlings by growing them and inserting them into the holes 1a as they are. Culture 4 in this case
May be made of the same material as the molding block 1. Further, as the soil to be stored in the hole used in this example, a commercially available artificial soil may be used. For example, as shown in FIG. 5, the shape is a truncated quadrangular pyramid, and the lower end has a smaller diameter. In addition, in the molding block other than planting the plant G,
You may use the thing without the hole 1a.

Another type of second molding block 1B
As shown in FIG. 6, the first molded block 1A is
The shape is cut along one vertical plane including the diagonal line on the upper end rectangular surface, and the upper end surface is triangular and the lower end surface is semicircular. However, this second molding block 1B is formed by cutting or tearing the first molding block 1A along the above-mentioned vertical plane, and by molding it into the shape of the second molding block 1B itself from the time of molding. It may be.

As shown in FIGS. 3 and 4, the installation condition in the cultivation container P1 is such that one first molding block 1A is provided at the center and each upper end rectangular surface of the first molding block 1A is provided on each side. Four surrounding first molding blocks 1A are arranged in contact with each other. The second molding blocks 1B are arranged in the spaces between the respective first molding blocks 1A around them. In addition, each molding block 1 arranged
Depending on each other, a proper void V can be formed partially (or entirely) instead of being in close contact with each other (see FIGS. 3 and 4). The molding blocks to be arranged may be arranged so that the sides of the upper end surface thereof are in contact with each other, or may be arranged at intervals of, for example, about 2 cm.

As described above, the planter P is the cultivation container P.
1, a plurality of forming blocks 1 alone are arranged, and the soil 4 is formed in the first forming block 1A at the center thereof.
Plant G is planted via. On the other hand, the soil 1 without the plant G may be inserted into the hole 1a of the other first forming block 1A, but by leaving the hole 1a as it is, a gap is positively formed in the forming block. Is possible,
Not only does it improve water retention and air permeability, but it can also support root growth without difficulty. In addition, the holes 1a are granular,
It may be used as a hole for inserting stick-shaped or jelly-shaped fertilizer.

According to the planter P of this embodiment, the voids V between the respective molding blocks 1 function as a guideway for improving the aeration and water flow conditions and for further widening the distribution of roots as the plant grows. To do. When the aeration and water flow are good, the growth of roots is improved and the plant can be cultivated stably. Further, in the case of using the molding block formed by molding the above-mentioned synthetic soil, if watering is performed, the molding block 1
The water can be evenly spread in the pores of the plant, water can be supplied to the plant G in a preferable state, and the nutrients provided in the molding block 1 can be efficiently absorbed by the roots of the growing plant. Furthermore, since the spread of roots can be accepted by the molding block 1, it is possible to grow the roots in a preferable state without inhibiting the growth of the roots. Of course, the molded block 1 is not tightly tightened as in the case of the conventional soil alone, so that it is possible to continuously support the growth of plants.

Next, a method of forming the planter P and a method of cultivating the plant of the planter P will be described. [1] Each of the above molding blocks 1A and 1B, the cultivation container P
