Description

  The present invention relates to hydroponics that grows plants with a culture solution in which artificial nutrients essential for plant growth are arranged in non-nutritive fresh water, and particularly relates to what is referred to as hydroponics because of the culture medium. is there. The fertilizer used here is a low-concentration of commercially available calcium nitrate, which is widely used in hydroponics, and a commercially available fertilizer with all the nutrients necessary for other plants down to trace elements. A culture solution prepared by mixing the above was used. These things are described in detail in Non-Patent Document 1 as hydroponics of vegetables. The medium is essentially water only, but a mixed medium of rock wool and hydroball was used because the plant rooted and supported itself and shielded sunlight from the root.

Problems to be solved by the invention

In conventional pot flower cultivation, soil containing abundant nutrients absorbed by roots in plant pots is cultured and used to plant flower seedlings, etc. Daily irrigation is necessary in conjunction with the environment and plant growth, and this work encourages growth and supplements with fertilizer as necessary to maintain and promote flowering. Irrigation work cannot be cut out even for one day.
However, when using the hydroponic method of the present application, in production cultivation, the potted bed becomes a fixed type on the cultivation bed that is being circulated while circulating the culture solution in which nutrients essential for plant growth are dissolved in a necessary proportion in advance. As long as the planted hydroponic pots are placed, it is possible to make the flowering grow much more labor-saving than soil-cultivated pots without being bothered by daily irrigation and fertilization. Ornamental cultivation after handing over can be continued with hydroponics by switching to a cultivation device combined with a water storage bottle, so there is no transplanting process that is a shock to the plant, and growth continues smoothly. By just checking the amount of water consumed by the eye and replenishing the culture solution once in a few days, you can grow and blossom a splendid plant that can not be beaten by a professional gardener and enjoy it to your heart's content. I can do it. The same culture medium can be prepared by the same method in both mass production cultivation and ornamental cultivation after reaching the hands of consumers. In other words, it can be converted to a technology that can be easily handled by women and children as long as the principle of mixing at low concentrations is observed.

Means for solving the problem

  The remarkable labor-saving production facility in the production and cultivation of the present application described above is a large rain gutter made of hard vinyl chloride with a core of 26 cm in width and 4 m in length used for the roof of a factory (actually made by Matsushita Electric Works) ) Is placed in the middle of the cultivation facility in a slanted shape to create a large-scale flower pot production bed, and the pot bottom of the hydroponics pot described later with a long sheet of hard vinyl chloride is inserted into this basket A large number of shaped bowls are molded in two rows, and glued to the inner surface of the bottom of the bowl, and a “stop” plate of water is glued to both ends of the bowl. Attach a drain elbow. This drainage elbow is provided as a drainage pipe for dropping water into the water storage tank. On the other hand, the culture solution in the water storage tank is circulated continuously to the upstream side of the production bed with a magnet pump or the like, and the culture solution is supplied from the bottom side of many flower pots arranged side by side on the bed. Absorbed into the entire medium, capillarally infiltrate the whole medium to support plant growth.

  The flower pots that are mass-produced labor-saving in this way are sold through distribution and passed to the consumer's hands. As a result, you will get a fertilizer divided into No. 1 and No. 2 and a hydroponic three-piece set such as “flower pot”, “water bottle” and these “receiving trays”. If the mixing is carried out carefully according to the instructions, the growth can be continued smoothly and smoothly without causing any problems. In addition, the material of the bowl and the saucer is a high-density foamed polystyrene, but it has significantly higher weather resistance than the low-density ones often used for packing materials, and the strength, lightness, and ease of molding of the present invention. The material is perfect.

Effect of the invention

In pot planting such as many flowers, the effect of the hydroponics system according to the present invention is extremely remarkable, but here, as an example, data of a comparative cultivation test by Petunia is listed as FIG. It is a hydroponic set of the consumer correspondence type of this application which arranged one water supply bottle 51 in the saucer 46 which mounts the two system bowls 1 hung up in FIG.
The seedlings that were sown and raised on April 5th were placed on both sides of the saucer on May 12th, with 2 bowls containing approximately 1 liter of medium mixed with rock wool and hydroball in half in a volume as the standard specification. The water supply bottle filled with the culture solution is placed upside down in the center of the saucer, and 2 sets (4 pots) are prepared for the comparative cultivation test as a hydroponic system bowl. On the other hand, four unglazed flower pots that contain the same amount of soil are set up as soil-cultivated pot pots as control plots for normal cultivation, and each is planted with seedlings that have grown to the same extent. Test cultivation was started. The hydroponic test section is usually replenished every 4 to 10 days until the water in the water bottle is lost by supplying the complete culture solution described above. Culture soil containing organic fertilizer and chemical fertilizer was provided, and irrigation to this soil cultivation area was carried out sufficiently on the water every evening until spilled water dripped from the bottom of the pot bottom.
In order to verify the degree of growth, the cumulative number of flowers was used. According to the graph, there was almost no difference between the two districts from June 11 to early July, but after that, the hydroponic system Hachi-ku of this application increased the sudden growth and flowering, and the final survey date On August 26, the hydroponic territory reached 544 times with 544 flowers compared to 142 cultivated in the soil. In the soil cultivation area, the vines that diverged in the early days were growing long, whereas in the hydroponics area, the vines were thicker, with many branches branching from the roots of the leaves, and still flowering. It seemed like a healthy development. This tendency of developmental difference was also observed for other flowers. Considering this fact, in the soil cultivated area, when the water is supplied once in the evening every day, the soil will be full when the water is supplied, but the water in the soil will gradually be lost over time. Although there are no abnormalities such as wilting, the plants are considered to be physiologically reasonably water deficient. In other words, if the state of moisture in the soil of potted soil is expressed as a graph, it will be a sawtooth-shaped curve that repeats daily water-filled and water-poor conditions, whereas the water in the hydroponic zone is It is inferred that the hydroponic zone will bring about an unprecedented result in the growth of the plant, since it always passes in the uniform horizontal water supply necessary for the plant.

BEST MODE FOR CARRYING OUT THE INVENTION

This will be described in detail below with reference to the drawings. FIG. 2 shows the system bowl 1 of the present invention as viewed obliquely from below, and the lower side surface has an arc shape 2 and the linear plane shape 3 has two shapes. Yes. And the opening part of the arch-shaped bottom net | network 4 of a bowl bottom is surely located by the side which has become circular arc shape. This bottom mesh 4 is made of 4mm square hard plastic, the arch height is 45mm from the bottom of the bowl, almost twice the normal water level, and the air contact with the root is perfect. Good without.
The effect of the bottom mesh 4 is that the fall of the medium 5 placed in the pot is prevented while blocking the fall and at the same time water and air are passed well. Therefore, the water level line in the sectional view showing the installation state of the pot bottom in FIG. Even if water is added up to the position, the upper roots and the medium 25 are well in contact with air, so that the roots can achieve healthy growth by fully absorbing the culture without causing root rot. As shown in FIG. 3, the bottom mesh 4 is fitted into the bottom mesh insertion groove 5, but both ends of the arch of the bottom mesh 4 are pressed from above by the body of the pot 1, so that the bottom of the bottom mesh 4 is firmly attached to the bottom of the bowl without coming out of the groove. Fixed. When the bottom net 4 is set in the bowl 1, it is inserted along the groove 5 from the side. However, in Japanese Patent Laid-Open No. 10-150870, the holding mechanism for the partition wall 9 is not clearly described, and in FIGS. 1, 2, 12, and 13, the bottom mesh insertion groove 5 for inserting the bottom mesh 4 in this application is used. There is no such expression. In this case, the air-permeable partition wall 9 is not accurately held, and the description on the third page, left line 32, that the notch groove 11 is vertically penetrated in the literature is incomprehensible and unclear. On the other hand, in Japanese Utility Model Publication No. 1-167154, unless the net cage 5 is fixedly set to the cultivation pot 1, a medium containing rock wool 6 and clay sintered grains 7 is added or a plant is planted. Because the medium intrudes into the net cage 5 due to the shaking at the time, the net cage 5 changes its posture or floats up in the medium, even if it can be drawn on an illustration, it is not actually useful.
Corresponding to the fact that the lateral bottom of the system bowl 1 of the present application has a different shape of the circular arc shape 2 and the linear flat shape 3 as described above, the shape of the water basin seat 18 to be described later is also an arc and a linear flat shape. In the mass production cultivation, the arched bottom net 4 is adapted to follow the flow of the culture solution so that the operator mistakenly puts the arched bottom net 4 of the pot 1 at right angles to the flow path. In order to avoid disrupting the flow of the culture and disturbing the uniform growth of the flowers, this cultivation bed has a structure that cannot be placed perpendicular to the flow from the beginning. FIG. 4 is an overall outline of the hydroponic cultivation apparatus, where the cultivation bed 6 forms a water channel that is gently inclined in one direction, and the culture solution 7 supplied upstream is arranged on the cultivation bed 6. While infiltrating the bottom of the system pot 1 planted with the medium filled, it flowed straight down without disturbing the inside of the arch, and dropped to the storage tank 10 from the drain elbow 9 attached to the water stop plate 8 at the bottom end. And stored. This culture solution 7 is continuously pumped up again by a magnet pump 11 or the like, sent to the upstream side of the cultivation bed 6 through the water supply pipe 12, and the circulation of the culture solution 7 is repeated. In the figure, 13 is a frame for supporting the cultivation floor, 14 is a foundation made of a concrete block below, and 15 is the ground.

FIG. 5 shows the structure of the cultivation floor. A large rain gutter 16 having a width of 26 centimeters, which is used for a factory roof, etc., is installed at a gentle slope. As shown in the figure, a water basin 18 is provided as depressions with a constant interval, but the water basin 18 is staggered in the left and right flow paths so that the plants in each pot planted are well-lighted, and An insole molded sheet 20 provided with a channel partition 19 is fitted over the entire length of the ridge 16 so that the left and right channel water flows independently, and is fixed with an adhesive or a caulking agent. The large rain gutter 16 is usually 4 m long for transportation, so the insole molded sheet 20 is also 4 m long, but if you want a longer cultivation floor 6, the parts on the rain gutter 16 side Since “connecting” is prepared, it is possible to construct an arbitrarily long cultivation bed 6 using an adhesive. The insole molding sheet 20 laid on the inner upper surface can be easily molded by two molding rollers heated from a flat hard vinyl chloride roll sheet. The cross section taken along the line A-B in the figure is shown as FIG. 6 of the cross section of the tunnel covering of the cultivation floor 6, but details regarding the tunnel cover will be described later. Compare the water level of the shallow ditch channel 22 at. The feature of the present application is that the flowing water is ridged in the portion of the water basin 18, and the culture solution 7 flows down at once without stagnation or overflowing. In the case of a saddle type, it refers to a channel recessed in a groove shape. However, the culture liquid is flowing down on the ridge water channel 23 in the dynamic water basin 18 which is a part where the pot 1 is installed in the present application. As shown in FIG. 6, this phenomenon is supported by the fact that the medium 25 at the bottom of the system bowl 1 loaded with being sandwiched from both sides is immersed in water to constitute a potential water level. That is, the shallow water channel 22 in the flat plate portion 21 and the ridge water channel 23 in the water basin 18 are connected at almost the same water level, and the culture solution 7 flows down continually through the ridge, thereby aeration effect. To achieve the perfect vitality of the roots. Since rock wool, which is one of the medium, is hydrophilic and easily wetted, the capillary action works well in the pot 1 and the culture solution 7 reaches the upper surface from the whole medium 25 filled in the pot 1 to the upper surface. The plant 17 planted in 1 can achieve very vigorous growth. Such a unique configuration of the pot 1 in the water channel is not found in Japanese Patent Laid-Open No. 10-150870.
6 in FIG. 6 is a steel equilateral angle steel generally called an angle, and serves as a rail that supports and supports the cultivation floor 6 while connecting the gate-type mounts 13 set up at appropriate intervals. Yes.

Thus, the temperature environment of the cultivation floor 6 in which the system pots 1 are arranged in two rows on the straw 16 has a requirement that it is very easy to control. That is, a piano wire column 27 for tunnel cultivation is erected at the edge of the large rain gutter 16 shown in FIG. Cover with. The hem of the film is a bulge on both sides of the large rain gutter 16 with a small screw on the body part of a casing rod 29 (called a mall in the commercial product) used for walls and pillars when wiring the wires indoors. Attach the hem of the film from above, and then apply the lid of the casing rod 29 and push it in from above to fix the film in an airtight manner. By doing this, a long and narrow tunnel cultivation facility with a transparent film can be easily formed on the long ridge 16, so that if the cold air is blown from one end, a considerable length of the cultivation floor 6 is locally cooled. It can be used as a cultivation facility. Such a thing is not described in Japanese Patent Laid-Open No. 10-150870 which is developed in mass production.
There is a dedicated agricultural air conditioner for creating cold air, but the use of ducts from home air conditioners, which are mass-produced as household appliances and are widely used, is simple and relatively inexpensive, deceiving the purpose of local cooling . In order to further improve the effect of such local cooling on hot summer days, a semi-light-shielding net is stretched on the roof of the house or glass room having this device, and a mist cooling device is further installed inside. It is effective to reduce the load on cooling as much as possible. Such a cultivation facility actually has a positive impact on medium and small-scale cultivation of cyclamen, which is difficult for the second summer over flat land, and there are other expectations over the summer of Primula. In other words, for large-scale farmers, cyclamen over the summer depends on the realization of relay cultivation that contracts with high-cold region farmers and transports a large amount of cultivation pots by large trucks, so cooling is significant as a measure for small and medium-sized farmers.

There are various forms of plants, but basically the flower stems and main stems that support the flowers are standing firmly by themselves, but for example, vines such as clematis, gloriosa, morning glory, etc. must be clung to some form. If you can not stand the appreciation. One of the methods that has been used since the Edo period is the “andon tailoring” technique, and there are still ukiyo-e that sell android bowls tailored for andon. It stabbed several thin bamboo sticks into the soil in the pot, and handed bamboo chin, wire, etc. to the upper two or three steps, and provided an entangled pedestal to attract vine plants. In this case, when the soil is soft or the amount of soil is small, the support is unstable and tilts or falls. Was used.
The hydroponic system bowl of the present application is not a small to medium pot, and the medium is a mixture of hydroballs made of cotton-like rock wool and clay baked, and the medium is lightweight. Because it is inferior in solidity as a support for "andon tailoring", special ingenuity was required.
FIG. 7 is a perspective view showing a mounting structure tailored to the present application, but a part of the bowl is omitted so that the internal structure of the bowl can be clearly seen. And usually the medium is filled with the pot, but when drawing this, the structure becomes invisible, so the medium was only partly drawn symbolically. The other figures are the same. FIG. 8 is a plan view of the system bowl 1 showing a part of the lower part of the present andoron tailoring in the bowl, and particularly the configuration of the mouthpiece 30 of the bottom end of the present andon tailoring structure is important. That is, the mouthpiece 30 is cut into a size that allows a stainless steel plate or the like to be placed on the crescent-shaped flat step 31 in the middle four positions in the bowl 1 and has a 4 mm diameter hole at its four corners. A wood screw with a diameter of 4 mm and a length of about 20 mm is passed through this hole. Next, commercially available struts for tunnel cultivation (length 1m, outer diameter 6mm, inner diameter 4mm) are cut into half 50cm to make the more and more tailored strut 32, 5mm from one end and 16cm intervals from there. Then, marks are placed at intervals of 28 centimeters, and 1.5 mm horizontal holes 32 are passed through the three places. In this case, the horizontal holes are all aligned in the same direction, and the preparation stage is completed.
Next, in the assembly stage, first, an adhesive is applied to the wood screw portion where the screw portion penetrates the stainless steel plate and is raised. , But set up so that the small holes of 1,5 mm are all parallel to the upper edge of the bowl at that location, as shown in FIG. . It takes a long time to write a sentence, but if you are skilled, you can complete the installation with almost one action. After that, if the piano wire 34 having a diameter of 1 mm and three steps in the horizontal hole 33 is stretched, the adhesive is cured and completed. Both ends of the piano wire 34 are completed as a circular ring if they are brought into contact with each other in the electric wire butt connector 35 and caulked with dedicated pliers. Reference numeral 36 denotes a lower side wall of the bowl, and 37 denotes a bowl bottom.
The mouthpiece 30 is made of stainless steel, but if it is made of hard plastic, it can be made by molding up to the wood screw at the same time. Can be procured.
Once assembled in this way, it becomes surprisingly strong and will not easily fall over or twist. These android tailors 32 are set together in the pot 1 when the vine plant seedling is planted, and are wound around as the foliage grows.

A typical plant has a main trunk and rises, and the twigs are primarily branched from the roots of these leaves, and arrows rise up. Many flowers bloom at their tips including the main trunk. The grass shape is determined by whether the main trunk is strong or the branch twig is strong, and whether it is a secondary branch or a tertiary branch.
Carnations and godets bloom at the tip of the primary branch, but they grow fairly large and heavy flowers at the end of the elongated branches. This grass shape is said to be a crowd of upside-down “brooms”, and as the varieties have improved and the flowers have grown, the stems are not rigid and require the support of flowering stems.
FIG. 9 is a perspective view showing a support structure for supporting such a crowded flower, and an attachment structure for tailoring this crowd. The lower end of a short stainless steel pipe 38 having a diameter of 6 mm and a length of 2 to 3 centimeters is held in a temporary support shape where it matches the height of the bowl edge, and one thick stainless steel wire 39 and a slightly thick stainless steel wire 40 are provided. 4 pieces are inserted from below and fixed by soldering or brazing. The lower end of the thick wire 39 is cut to a length that reaches the bottom of the bowl, and is bent into a loop 41 at the position shown in the figure that is the same height as the top of the bottom mesh 4 and thrust into the eye of the arch-shaped bottom mesh 4. However, since there is a loop processing part, it does not move left and right before and after standing up at a certain depth at that position. On the other hand, the slightly thick wires 40 are horizontally spread at right angles and bent downward into the medium 25 at a position where the tip is inside the upper end angle of the system bowl to form a stick. With this structure, a structure in which the lower part of the column is not fluttering is created.
Further, on the upper side of the short stainless steel pipe 38, a slightly thin stainless steel wire 42 having a length of 15 to 28 centimeters, which is seven in the drawing, is fixed by welding in the same manner as described above. At the time of use, as shown in the figure, it is opened obliquely upward, and the tip part is subjected to a small loop-shaped bending process 43, and into the loop through a crowded support piano wire 44, it is formed into a ring shape with a thin wire butt connector 35. Close. The piano wire may have a two-stage ring by changing the size of the ring according to the nature of the plant, or by adjusting the length of the wire 42. It is important to use stainless steel for the wire here, but it is also important that it does not rust, but at the same time, the hardness is greater than that of iron and because it is the same quality as the stainless steel pipe, it is easy to weld with solder etc. It depends on things.

Some types of plants do not have too many side branches and only one main trunk grows upward. Typical ones are delhinium and sunflower, which are originally in great demand as cut flowers. Although such a plant stem is solid, it cannot be supported straight by a soft rock wool-based medium as in the present application. Therefore, it is necessary to attach a solid upright support post. FIG. 10 is a perspective view of an upright single tailored column.
The structure of the lower part is exactly the same as Figure-9, but the upper part is only upright with a long stainless steel pipe 45 with a diameter of 6 mm, but the top part is to prevent rainwater from entering and improve the appearance. Put an inconspicuous lid stopper on. The length of this pipe is about 25 to 40 centimeters, depending on the type of plant, but it should be 1/3 to 1/2 at most of the planned final growth height. Is preferred. In other words, the number of attracting points to the column is reasonable about 2-3.

The final consumer of flower pots grown by the hydroponic system pot 1 according to the present application is the consumer. For this reason, the flower pots produced by hydroponics must be inherited in the form of hydroponics that allows them to grow wonderfully even after they reach the hands of consumers.
Irrigation is an indispensable daily work for potted flowers in soil cultivation, and fertilization is a place where everyone is worried about the quantity and quality. The present application can solve the troublesome labor of daily watering and the trouble of fertilization at once by making the culture solution and automatically supplying it.
Even a professional gardener cannot know exactly how much moisture and nutrients a plant wants. However, the hydroponic flower pot after reaching the consumer's hand is an automatic water supply of the required amount of water, and the amount of water consumed by the plant is displayed in the form of reduced water, so the culture solution exceeding that amount is bottled It is only necessary to replenish 51 so that the water is full, and since the optimum type of nutrient is always supplied in an appropriate amount, there is no problem with this. Since oxygen is sufficiently supplied to the roots from the large arched bottom net 4, this is not a problem at all. The only difference between the production cultivation floor and the consumer is the difference in whether or not the culture fluid is flowing, and the depth of the water channel of the saucer is only 27 mm, which is a shallow water level. Oxygen is sufficiently supplied to the culture medium contained in the root and its surrounding medium. This is clear from the results shown in Fig. 1, and the reputation from the consumer's hands is very good.

The last is the capacity relationship of the water supply bottle 51 that supplies the culture solution to one hydroponic pot 1, but FIG. 11 shows a consumer standard type that feeds two pots 1 with one water supply bottle on the tray 46. . Most of the flowers can be cultivated well in this manner, but if you want to enjoy the growth as a stand-alone stand-alone pot, or if you want to keep the water supply interval, the culture solution will be 1 bottle 1 to 1 bottle 52 as shown in FIG. When the number of water supply bottles 52 is increased to two as shown in FIG. 13, the amount of the culture solution is four times that of the consumer standard. The heyday of delhinium necessitated exactly 4 times the amount of culture.
FIG. 11 shows the main points of the present application as a three-piece set of two bowls 1, a tray 46, and a water bottle 51 as a standard configuration for consumers. 47 is a water basin 47 of the saucer 46, and corresponds to the arc-shaped side surface 2 and the straight planar side surface 3, which are the shapes below the basin 1, in the same manner as the moving water basin 18 in the mass production cultivation floor 6. The saucer 46 also has an arc shape and a linear planar shape. That is, the culture solution 7 from the water supply bottle 51 is configured so that the opening portion of the bottom net 4 is always brought into contact therewith via the water guide groove 48 so that the water 7 can be smoothly supplied. This is a feature of the present application which is not described in the Published Utility Model Publication No. 1-167154 and the Published Patent Publication No. 10-150870. In FIG. 11, the water supply bottle 51 filled with the culture solution 7 is set to the water supply bottle seat 50 in the central portion of the tray 46. First, the lid 52 is closed, and the two bottle water supply holes 53 in the center of the lid 52 are set. Is closed with two fingers and turned upside down and fitted into the water supply bottle seat 50. The seat 50 has two stages, and the bottle 51 is stopped by the middle bottle receiving stage 49 and the culture solution 7 is discharged until reaching the middle level. When the water surface reaches the bottle water supply hole 53, the atmosphere is discharged. Thus, the culture solution in the bottle 51 is suspended in the air and the water supply is stopped. In this way, only the amount of water that the planting plant 17 needs to absorb is replenished, so the culture solution may be replenished so that the amount of water in the bottle is filled and the water is filled each time. Since the bottle 51 can store a considerable amount of water, it can save labor from daily irrigation work, simplify the watering and fertilization work, and is a simple method that can be handled by elderly people, women and children.
Thus, the hydroponics system pot 1 of the present application supports the mass production cultivation of potted flowers using large rain gutters due to its unique shape, and this cultivation method enables local tunnel covering in a row. It can be used for air conditioning, etc., and an advanced cultivation environment can be prepared. Moreover, even if the pot capacity is relatively small as in the present application, it solves the strut problem due to pots corresponding to andon tailoring, crowding tailoring, and upright single tailoring, and at the same time increases the water supply capacity as necessary By one thing, it can be filled with one hydroponic system pot 1 from a small pot flower to a pot flower that grows to a long size. This is not found in patent documents such as the published utility model publication No. 60-168363, the published utility model publication No. 1-167154, and the published patent publication No. 10-150870, and shows the characteristics of the present application.
