Utility model 2555201 JP 2005-027542 A JP-A-10-327690

  In the past literature of bottom irrigation, there are many bottom irrigation devices that use a water supply string and a water supply device to suck water with a capillary tube, but the water absorption device of the water supply string is not specified for the ability to absorb water. There is no explicit indication of the amount of siphoning. Without this presentation, the length of the water supply body cannot be determined, and the size and depth of the flower pot, the stand, and the water tank cannot be determined.

  In the present invention, in order to solve the problem, the ability of sucking up the capillary tube is examined by experiment. In the plant bottom irrigation device, the water supply body is made of a mop-like cotton or a microfiber which is a fine fiber and bundled with a flexible 1 cm-3 cm diameter. -A sucked lower part in which a core part formed in a cup shape is sucked up and covered with a core cover to prevent evaporation of water, and the upper end of the core part is 3cm-5cm in diameter with cotton showing a liquid phase of about 50%. It is composed of the upper part of the bundling part that binds to a cylindrical shape of 2 cm to 3 cm. As a result of bottom irrigation by capillary action from the lower tank, the length from the bottom of the bundling part to the tip of the lower part of the suction is 13 cm-16 cm Was found to be a stable uptake height, so the size and length of the water supply body were specified above, and the flower pot has one water supply attachment hole with a diameter of 1 cm in the center of the bottom up to the No. 5 flower pot. 6- Until the issue pot, one of the mounting hole of 3cm in the center. There are two 9-12 bowls. In No. 13-15, there are three mounting holes, and a water supply body is inserted into the hole to perform bottom irrigation cultivation. The pedestal is not fixed in shape and is as high as 0 cm-14 cm from the upper edge of the water tray. In the upper part of the pedestal, there is a horizontal place where the flowerpot can be placed stably, and there is a space with a diameter of 1cm-3cm or more into which the water supply body is inserted. It has a plurality of water entry holes so as to enter, and the tray part uses a standard water basin with a suction capacity limit depth of 12cm-15cm for the water supply body, but when it exceeds 12-15cm, measures to dry the soil As a deep water board, a horizontal water supply line is drawn from the bottom of the flower pot to a position 12-15 cm below and inside the saucer, and a horizontal overflow prevention line is also provided horizontally at a position 1 cm below the top of the edge. It is characterized by cultivating aquatic plants at the same time

In the present invention, the suction capacity of the capillary tube was examined by experiment, and the stable suction height was found. Therefore, the length of the water supply body was determined, and the depth and height of the water tank and the stand were also determined. Thereby, the water retention amount of the water tank can also be set. The water tray placed at the bottom of the pot is large and has a large capacity, so that a large amount of water can be secured, the amount of water can be seen visually from the outside, and water can be easily replenished. It can be attached to pots of various shapes, and can be combined with a pot stand and a water tray. This expands the possibility of various bottom irrigation cultivation and secures a large amount of water, enabling simultaneous cultivation of aquatic plants.

An embodiment of the present invention will be described below in detail based on an example of implementation with reference to the drawings.
FIG. 1 shows an example of a combination of plant bottom irrigation tools. This is a combination of a flower pot B, a pedestal C, and a water tray D equipped with a water supply A. The water F retained in the water tray D is sucked up by the water supply body A into the soil E of the flower pot B with the capillaries and plants and the transpiration of the surface of the soil E.

  In order to examine the ability of the water supply body A, the water supply body A in the plant bottom irrigation device sucks up the core 1 formed into a flexible rope shape by bundling mop-like cotton or micro cloths, which are fine fibers. Suction lower part H covered with core cover-2 to prevent evaporation, and upper part G of water holding the upper end of the core part in a cylindrical shape with a diameter of 5 cm and a height of 3 cm with cotton showing a liquid phase of about 50% The water supply body A having a length of 20 cm from the bottom of the bundling portion 3 to the tip of the suction lower portion H is fixed to the bottom of the flower pot B, and the diameter of the suction lower portion H of the water supply body A is 1 cm, 2 cm, 3 cm, 4 cm Change it to 5cm, fix it, place a dry small swamp soil with strong water absorption on it, suck water F from the lower water tray D by the water absorption power of Kanuma soil and the capillary action of the water supply A, and dry Measure how the weight of Kanuma soil changes by sucking water F. Kanuma soil, 3000cc, temperature 18 degrees. It was measured at a humidity of 30%, half-shade, no wind, and a suction distance of 2 cm. As a result, a difference in sucking amount due to a difference in diameter of the sucking lower portion H occurred. The 24-hour equivalent suction volume is 1cm and 750cc. 2cm, 1170cc. 3cm, 1470cc. 4cm, 1500cc. Since the thickness was 5 cm and 1520 cc, an effective thickness of 1 cm to 3 cm is set as an effective thickness.

A wicking test was performed under the same conditions by changing the size of the tying portion 3 to see how the size of the bound water retaining upper G affects the wicking amount, but no difference in the wicking water amount due to the size occurs. By using 50% cotton for the bundling section 3, excessive moisture damage is reduced in the bundling section 3 formed with a normal cotton liquid phase and a high liquid phase of 80-90%, and wicking due to root entanglement The decrease in ability is also reduced.

Measure the amount of water F sucked up due to the difference in distance by changing the suction height. The suction distance was changed at the lower suction H having a diameter of 3 cm. Several experiments were performed and average values were obtained. Height, distance 2cm, 1470cc in terms of 24 hours, 5cm if this is 100%. 1470cc. 100%. 10cm, 1410cc. 96%. 15 cm. 1050cc. 71%. 20cm, 600cc. 41%. As a result, when the diameter is 3 cm, the specified suction height is 15 cm. Next, the suction distance was changed at the lower part H of the suction part having a diameter of 1 cm. Distance in terms of 24 hours: 2 cm, 750 cc, 100. 5 cm, 750 cc. 100%. 10cm, 720cc. 96%. 12 cm. 530cc. 71%. 15cm, 250cc. 33%. The stable suction height regulation at 1 cm is 12 cm.

  The amount of water to be absorbed varies depending on the season, temperature, humidity, wind, plant to be planted, and the size of the plant, but the amount of water to be absorbed in winter is small and 100 cc in 24 hours after using a 3 cm diameter pot No. 10 and planting a pansy In summer, when planting a large petunia plant in the same pot, more than 1500 cc of water F was consumed from the water pan D. Sucked water consumption due to the transpiration of leaves during the growing season of plants shows a large proportion of water consumption. When a plant was planted at the time of drying and a cultivation experiment was carried out, a case where the moisture of the soil E could not keep up with the transpiration from the surface and the surface of the soil E dried was generated. However, the inside does not dry rapidly due to the surface tension of water F. When the soil E in the flower pot B is examined in a dry state on the soil surface in summer, the root part of the plant maintains a liquid phase ratio of 25% or more, and the effect of water deficiency on the plant is small. Water F is sucked up from below by the power of the roots. However, the number of water supply bodies A needs to be increased depending on the size of the flower pot B. Further, depending on the use conditions, when the soil E is too dry, the soil E can be prevented from drying by a treatment such as moving in the shade. In addition, by irrigating from above, the air inside soil E can be replaced, and oxygen supplementation, chlorine removal, and disease disorders can be prevented in soil E. It is desirable. Moreover, it is desirable to cultivate the liquid phase of soil E at 25% or more. If the liquid phase is too low, the capillarity inside the soil E and the osmotic action may deteriorate, resulting in excessive drying.

The percentage of soil E containing moisture can vary depending on the type of soil mixed. The liquid phase of soil E can be made high or low by mixing sphagnum with a high saturated water content or pearlite with a low saturated water content. Since it is bottom irrigation, the moisture content of the soil E is constant, so that it does not become excessively humid and is not dried by holding water in the water tray D. Even if you do not replenish the water F for more than a week by securing the water in the water tray D, it will not dry up, so you can travel for a long time.

The flower pot B has one water supply mounting hole 6 with a diameter of 1 cm at the bottom center to the No. 5 flower pot, and one 3 cm water supply mounting hole 6 at the center up to the No. 6-8 pot. No. 9-12 bowl has two water supply mounting holes 6. In No. 13-15, there are three water supply body mounting holes 6, and the water supply body A is inserted into the water supply body mounting hole 6 to perform bottom irrigation cultivation.

  The table C is not fixed in shape, and the height is set to 0 cm-14 cm from the upper edge of the water tray D. The upper part of the table C has a horizontal plant pot holder 7 on which the flower pot B can be stably placed. The water supply body A has a space with a diameter of 1 cm-3 cm or more, and the sole portion has a plurality of water entry holes 8 so that water can easily enter.

In the plant bottom irrigation device, the water receiving tray D part uses the water sink A suction capacity limit depth of 12 cm-15 cm as a reference basin, but if it is formed to exceed 12-15 cm, the bottom of the flowerpot B as a countermeasure against drying of soil E From the bottom, a horizontal water supply line 5 is provided at a position 12-15 cm below and inside the water tray D, and measures to prevent drying are provided. An overflow warning line 4 is also provided horizontally at an internal lower position 1 cm from the upper edge of the rim, and as a countermeasure when used indoors, the water receiving tray D is cultivated at the same time as a deep water board.

If cutting and seeding are carried out by this bottom irrigation method, irrigation from above is not necessary, and soil E does not move with watering. Establishing germination of cuttings and sowing is high.

Even if it is difficult to water, especially planting and bonsai cultivation, adjustment of soil E will be easy if done well.

The plant bottom irrigation device of the present invention is labor-saving, hygienic, the liquid phase of the soil becomes constant, and the soil condition according to the plant environment can be ensured by adjusting the mixing ratio of the soil, so watering becomes easy, Even elderly and children can enjoy plant cultivation, and long-term travel is possible by securing water in the water tray. In addition, as a new utilization of hydroponics, a new cultivation form can be expected as a floating flower bed in combination with a laver.
