Description

  The present invention relates to a method and apparatus for extending the life of a plant cut from a root.

  Plants extend their roots deep into the ground and inhabit by absorbing water containing nutrients from the vast root surface area. Plants absorb nutrients through changes in water pressure in the conduits of water that evaporates from the leaves. When the trunk or branch is cut, it loses its function and dies. If the cut part is placed in water, it is alive for a while but does not last long.

The reason why plants with cut trunks or branches in water do not last long is thought to be largely due to the loss of evaporative circulation function and the decline of plant vitality. If plants inhabit only by the evaporative circulation function, plants that have been submerged in water should not wither, but they will wither. In addition to the function of absorbing water, the role of roots can be thought of as the force that pushes water into the plant, in other words, the force that pushes water into the inside. Based on such an idea, pressurizing nutrient water and applying pressure to push the nutrient water into the cut part of the trunk of the plant, the plant does not die, it is an experiment that grows stronger than before cutting I was able to confirm.
The main object of the present invention is to inhabit a plant energetically for a long time by supplying pressure water to the cut part of the trunk or branch of the plant.

In order to achieve the above-mentioned object, the present invention provides an insertion portion for receiving a cut portion of a trunk or a branch of a plant cut from a root in a container to which nutrient water is supplied, thereby increasing the water pressure of the nutrient water filling the container. In addition, the water pressure of nutrient water is applied to the cut portion of the trunk or branch inserted into the insertion portion, and the nutrient water is pushed into the trunk or branch by this water pressure.
The present invention also includes an air pressure adjusting mechanism that outputs air with increased pressure from a discharge port, a water absorption tank that is connected to the air pressure adjusting mechanism and discharges high-pressure water from an outlet, and an insertion portion. A pressure water supply connection mechanism that applies high-pressure water pressure supplied from the water-absorbing tank to the cut portion of the trunk or branch of the plant inserted into the insertion portion, and pushes the high-pressure water into the trunk or branch; It is equipped with.
In the present invention, the pressure water supply connection mechanism includes a container connected to the water supply tank and a rubber body having an insertion part and attached to the container, and the insertion part has a substantially conical shape. is there.
In the present invention, a plurality of plate-like ribs are integrally formed on the outer peripheral portion of the insertion portion, the side surfaces of the rib are pressed against the inner wall surface of the container, and the container is sealed to the insertion portion by the pressing force. The rubber pressure is applied in the direction of the movement.

  The present invention can inhabit fresh flowers for a long time. Large trunks can also inhabit, and large flowers can be designed on a concrete floor. In addition, trees that do not require soil can be grown, and plants can be cultivated in a small space. Moreover, since the soil weight problem can be solved, the weight problem of rooftop greening can be solved.

A water supply tank 16 is connected to the upper part of the water supply tank 4 via a pipe having an open / close valve 18, and water is supplied from a water supply source such as a water supply connected to the water supply port 16 through the water supply port 16 and the valve 18. 4 is configured so as to be supplied to the inside. In the water supply tank 4, a water level detection unit of the water level alarm 20 is installed.

When the water level in the water supply tank 4 reaches a predetermined water level, the controller (not shown) opens the valve 18 and is automatically controlled so that the water in the water supply tank 4 maintains the predetermined water level. An outlet 20 for discharging internal water to the outside is provided at the bottom of the water supply tank 4, and a water supply pipe 22 for performing hydraulic water supply is connected to the outlet 20. In the water supply path of the water supply pipe 22, a fertilizer tank 24, a backflow prevention valve 26, and branch pipes 28 and 28 containing water-soluble solid fertilizer are sequentially provided from the upstream side.

Pressure supply / water supply connection mechanisms 6 and 6 are connected to branch ports 28 and 28 provided in arbitrary numbers via pipes provided with a water supply valve 30, respectively. As shown in FIG. 2, the pressure water supply connection mechanisms 6 and 6 are made of a rubber material on the upper portion of a container 32 including a cylindrical portion 32a having a nut screw cut on an outer peripheral portion and a funnel-shaped bottom portion 32b. An upper portion 34 a of the packing body 34 is attached by a fixing nut 35. The packing body 34 has a ring-shaped collar portion 34a and an insertion portion 34b formed in a conical shape.

A plurality of plate-like ribs 36 extending in the axial direction are integrally formed on the outer peripheral surface of the insertion portion 34 b at substantially equal intervals, and the open end side edge 36 a of each rib 30 is formed on the inner peripheral surface of the container 32. The insertion part 34b is configured to be subjected to rubber pressure in the direction in which the insertion part 34b is closed by the pressure applied by the pressure bonding. As shown in FIG. 4, the ribs 36 are formed such that their cross-sectional shapes are bent in a bow shape. By this bent shape, the packing body 34 is moved from the opening to the cylindrical container 32 a of the container 32. It is easy to press fit along the axial direction.

The packing body 34 is configured so that the inside of the container 32 is in a sealed state, and water pressure is applied when water is pumped inside. The closed portion of the insertion portion 34b can be expanded against the elasticity of rubber so that the trunk or branch of the plant 38 can be inserted. At this time, the insertion portion 34b is plugged by the inserted trunk or branch so that the high-pressure water in the container 32 does not leak to the outside.

  In the configuration described above, the open / close valve 18 is opened by the control of the controller or by manual operation, and the water supply tank 4 is filled with water up to a predetermined water level. On the other hand, the air pressurization adjusting mechanism 2 is driven, and air is pressure-fed to the water supply tank 4 through the air pressure supply pipe 8, and the inside of the water supply tank 4 is set to a predetermined high atmospheric pressure higher than the external atmospheric pressure. When the water supply valve 30 is opened, the water in the water supply tank 4 is supplied as nutrient water through the water supply pipe 22 into the container 32 of the pressure water supply connection mechanism 6.
