Description

[Detailed description of the invention] "Industrial application field" A cultivation bed that simplifies and saves labor for cultivating useful plants in greenhouses such as vinyl greenhouses, promotes the growth of cultivated crops, and reduces the cost of crops. Pertains to.

``Conventional technology'' In recent years, the number of farmers has been decreasing, and on the other hand, crops are being grown in greenhouses such as plastic greenhouses in order to harvest them early. Furthermore, with the decline in the farming population, farmers are aging, and soil cultivation itself is becoming a significant burden on farmers.In addition, continuous cropping failure occurs in the soil, making it necessary to replace or disinfect the soil. It is becoming difficult to cultivate useful plants.

In order to facilitate this cultivation, cultivation beds called rock wool or slag wool (hereinafter simply referred to as rock wool), which do not require soil cultivation and are made of rock fibers or mineral slag fibers, have become commercially available. However, since these rock wools are simply cultivation beds made of hardened mineral slag fibers, etc., the absorption roots of crops are not distributed in the center of the bed, but are limited to the bottom and sides of the bed where they easily come into contact with the air. The actual amount of roots was also very small. In addition, when cultivating useful plants in Rotsukuru, only liquid fertilizer can be used.
I was facing very complex problems.

``Problems to be solved by the invention'' The inventor of this invention solved the shortcomings of the conventional technology, that is, there is no need for soil cultivation, there is no problem with continuous cropping, and even the elderly can efficiently grow useful plants. As a result of careful consideration of the cultivation method, we decided to create a cultivation bed by providing through-holes in a plate-like material made of an aggregate of rock wool, etc., and constructing a cultivation bed by blocking the through-holes between the two plates. The inventors have discovered that it is possible to promote the growth of plants by allowing the absorbing roots of useful plants to flourish into the center of the cultivation bed, allowing frequent contact with air and fertilizer, and thereby devising the present invention.

That is, the present invention provides a plant cultivation bed made of a plate-like material having a special shape and made of an aggregate of inorganic fibers or plastic having open cells.

``Means for Solving the Problems'' Therefore, the gist of the present invention is that the material is made of an aggregate of inorganic fibers or plastic with open cells, and has a suitable thickness with a plurality of through holes at appropriate intervals. The plant cultivation bed is characterized in that it is constructed by stacking two plate-like materials one on top of the other so that the respective through holes are mutually closed.

To explain the present invention in detail, the inorganic fiber aggregates used in the present invention include, for example, rock fibers (rock wool), mineral slag fibers, glass fibers, quartz fibers, silica fibers, ceramic fibers, carbon fibers, and silicon carbide fibers. At least one type of fiber made of an inorganic material such as fibers is assembled into a plate-like material to the extent that water can be retained with or without a binder. The plate-like material is formed by subjecting inorganic fibers to an appropriate thickness, for example, compression molding, and then cutting the inorganic fiber as it is, or by cutting the inorganic fiber to an appropriate thickness from the compression molded material.

In addition, plastics with open cells that can be used in the present invention are generally polyurethane,
A thermoplastic resin such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc. is foam-molded into open cells, and it is formed as is or by cutting it into a thick plate as appropriate. A plurality of through-holes are provided at appropriate intervals, preferably at regular intervals, and the through-holes are circular and have a diameter of about 2 to 5 cm, and rectangular with a side of about 2 to 4 cm. It has a cylindrical or prismatic shape. The through-holes may be provided when forming the inorganic fiber aggregate, or may be formed after forming the inorganic fiber aggregate. The through holes in the plate-like object made of plastic having open air cells may be provided when the plate-like object is molded as described above, or they may be formed after the plate-like object is formed.

The plant cultivation bed of the present invention is constructed by stacking two plate-like materials as described above one above the other so that the plurality of through holes are mutually closed.

The plant cultivation bed of the present invention will be explained in detail using drawings.

Fig. 1 is a perspective view of an example of the plant cultivation bed of the present invention, Fig. 2 is a plan view of a seedling bed placed on the cultivation bed of Fig. 1, and Fig. 3 is a perspective view of the plant cultivation bed of the present invention. - It is a longitudinal cross-sectional view of the A line. In the figure, 1 is a cultivation bed, 2 and 2' are
The upper and lower plates are respectively made of aggregates of inorganic fibers or plastics having open air bubbles, and have appropriate wall thicknesses; 3 and 4 are through-holes provided in the upper and lower plates, respectively; 5 is a seedling-raising plate; The floor, 6 indicates useful plants, 7 indicates a synthetic resin film, and 8 indicates embankment.

The plant cultivation bed 1 of the present invention has upper and lower plate-like objects 2
and 2' are stacked one on top of the other, and as shown in the example of use in FIG.
The through holes are closed. The plates 2, 2' thus formed may be covered with a vinyl chloride resin film, a polyethylene film, etc. (not shown) in order to prevent the retained moisture from evaporating.

The plant cultivation bed 1 of the present invention is normally used in a greenhouse such as a vinyl greenhouse, for example, as follows. First, the cultivation bed 1 is placed on a well-drained cultivation bed (not shown) to prevent excess water and liquid fertilizer from accumulating, or it is placed on a cultivation bed 7 made of synthetic resin such as vinyl chloride resin film or polyethylene film. It is placed on top of the covered embankment 8. As shown in FIGS. 2 and 3, on the cultivation bed 1 thus constructed,
Seed beds 5 with plant buds or seedlings 6 are placed at appropriate intervals, or seeds are directly sown or plant seedlings are planted on the cultivation beds 1. Solid fertilizer is loaded into the through-holes 3, and the growth of the plants is measured by watering them from a watering pipe (not shown) placed in advance on the cultivation bed 1.

"Effect of the invention" The plant cultivation bed 1 of the invention consists of two plate-like materials having a plurality of through holes made of an aggregate of inorganic fibers or plastic with open air bubbles stacked one on top of the other, and Since the pores are blocked by the other plate-like material, water is appropriately retained through irrigation, and excess water does not accumulate, and air circulation allows the plant's absorption roots to have many opportunities to come into contact with the air. This allows absorption roots to grow all the way to the center of the cultivation bed, allowing plants to grow quickly and being stably fixed to the cultivation bed even as they grow taller. In addition, solid fertilizer is loaded into the through hole 3 provided in the cultivation bed 1,
Simply watering promotes plant growth, and since water does not accumulate in the holes 3, root rot, suffocation, and other phenomena do not occur, and the roots grow even more vigorously, widening the root distribution area, making it easier to harvest crops. can be done quickly. Furthermore, since solid fertilizer can be used, there is no need to adjust the pH and ingredients as with liquid fertilizer, and all you need to do is water. Therefore, it reduces labor and makes it extremely easy for both young and inexperienced farmers to grow plants, and there is no problem with continuous cropping, which simplifies management and reduces production costs. leading to a reduction in
The industrial value is enormous.
