Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floating model hydroponic cultivation method that utilizes buoyancy and capillary action of perforated holes, using styrofoam to grow shellfish radish as a sprout-like softened vegetable.

The traditional method is to drill holes in a Styrofoam plate.
There are various cultivation tools for vegetables and flowers that utilize buoyancy, in which seedlings grown in other media are inserted and the mirror plate itself floats in the culture medium, and roots, stems, and leaves grow across the mirror plate, but the top of the plate is lower than the liquid level. Because the water is located high, it is not possible to permanently moisten the top surface of the board through wide-diameter holes.Also, there are types that immerse the top surface of the board in the liquid with weight, but this results in too much moisture for the seeds. , only the mirror plate is used as a growth medium without using gravel, making it unsuitable for direct sowing. Other methods are known, such as using gravel, sponge, etc. as a medium, floating mounting methods, and erecting a net in a water basin, but all of these methods require appropriate humidity for seeds to increase germination efficiency. It was essential to find ways to maintain the water level, and this required management that understood the positional relationship between the seeds and water level, as well as water level control devices, which was a huge burden in terms of economics, technology, and labor.

The purpose of this project was to eliminate the above-mentioned unreasonableness, create a high-quality production method and seedbed for Kaiwari radish, save labor from sowing to harvesting to shipping, and maintain quality in the distribution channel. To explain according to the diagram...Styrofoam floor board S has a thickness of 2 m, an area of 15 cJ, and a ratio of 101:111.
Approximately 50 through holes 1 with a diameter of approximately Q and 5 m to 31 m are installed in the part.
0 to 1000 holes are formed in a honeycomb shape and the frame 2 is formed, and the weight of the floor board S is extremely light, less than +55i+. The floor board S is to be floated in a water reservoir 3 filled with a culture solution ■'.
Immerse it about 2MIL below the liquid surface (d immersion line 7) and float. This light and outstanding buoyancy is such that a load of 300y is required to level the upper surface 5 of the floor plate with the liquid level 8. This is sufficient buoyancy even when the total weight of the shellfish radish reaches 200 to 250 y upon completion of growth. Further, the diameter of the through hole 1 is arbitrary depending on the type of seed, but in the case of shellfish radish, a diameter of 15 m to 2 m is appropriate. The seeds are sown on the through-hole through which the seeds cannot pass, and the bed board S is pushed down below the water seepage line 7, submerged in the culture solution up to the inside of the provided frame 2, and the bed board is brought up to the water seepage line 7 again. When the seeds 6 are wetted and evenly distributed over the many through holes 1, the seeds obtained here and the moisture inside the through holes are
It can be permanently held due to the capillary action of the through hole 1. In the present invention, the moist state once obtained is maintained at a constant level, unaffected by dry air, as long as fresh culture solution is maintained during the growth period from germination to cotyledon development, shipping, and distribution processes. naturally provides adequate wetting to the material above the through-holes. The production of cotyledons and hypocotyls during seed germination is easily affected by overhumidity and dryness, which causes delayed germination and uneven growth, so it is necessary to maintain an appropriate and constant level of humidity. No. The effect of the cultivation method using the bed board S of the present invention is great, for example, as shown in Figure 3, the bed board S gradually reaches the water inundation line 7 due to the weight that increases moment by moment at the same time as germination occurs. However, this change does not affect the wet state above the through-hole at all.Furthermore, it responds to changes in the water depth of the culture solution W by floating up and down freely in the water reservoir, causing depletion of the solution. As mentioned above, unless otherwise specified, the capillary action and self-buoyancy of the bed S will provide appropriate and sufficient moisture and stabilize growth.This eliminates the need to adjust the liquid up and down, making it more efficient in terms of equipment and growth management. This simplified the process and lowered production costs.

The through-hole l of the bed plate S becomes a passageway for roots due to the growth of the root at the tip of the hypocotyl, and the through-hole absorbs sufficient humidity and atmospheric oxygen necessary for growth, and the root gradually immerses into the culture solution. This allows the hypocotyl to elongate by taking in nutrients. Seeds 6 were sown densely to avoid lodging of the stems, grew to a hypocotyl length of 7 crn in about 5 days, and were gradually exposed to sunlight to produce a high-quality harvest. When the growth is completed, the bed board S is submerged in the liquid up to the B flood line 9, which is 5.2 m below the top surface of the bed board. Since roots do not grow in the through holes, no residual roots are seen, and the bed board S can be used repeatedly after harvesting, making it economical. According to the cultivation method using the floating bed type cultivation tool of the present invention, for large-scale production, the size and quantity are determined based on the buoyancy design as described above of the very inexpensive styrofoam bed S. Production is now possible in culture solution reservoirs of various sizes, and by applying a water flow to the culture solution W, the bed plate S, which has been sown in one place, is flowed in a raft shape and pooled, and during harvesting, it is placed in the position where the worker is sitting. It is also possible to streamline the labor involved in floating and transporting the work. In addition, floor board S tailored to the minimum retail unit
9 quality can be maintained during the distribution process by placing the seedlings with roots in a container containing culture solution and shipping them.
As shown in FIG. 4, it is also possible to sow seeds in a small container 10, such as a plastic bag, floating in a small container 10, such as a plastic bag, which serves as a water reservoir, wait for them to grow, and then ship the seeds in large quantities in the same shape as they were produced. In this case, the frame 2 is not needed and the container 10 is used instead.

As explained above, if the present invention is used to produce sprout-like softened vegetables such as shellfish radish, harvests can be obtained throughout the year (germination temperature 20°C) even with only water. In addition, if the method of cultivating it in a case that serves as a water reservoir and shade from the sun spreads, hydroponic cultivation can be easily produced at home or in a restaurant in a short period of time, and it is cheaper, cleaner, and reliable than the market price. It can also be used to provide shellfish radish as a natural food, and can be implemented in many ways.
