Description

  The present invention relates to a plant carbon dioxide assimilation promoting device and a method for promoting the same.

In general, there are fewer plants in the urban area and factory area than in the outside of the city. Therefore, a lot of plants are placed inside and outside the office, house, and factory buildings to increase the greenery. These foliage plants give people fatigue relief and relaxation effects from the senses of vision and smell (by the scent of flowers, etc.). Moreover, the foliage plant has the ability to clean contaminated air containing nitrogen oxides, carbon dioxide, positive ions, and the like by carbon dioxide assimilation. If this ability can activate a plant and promote a carbon assimilation action, an effect will increase and it will become more preferable. On the other hand, people who operate agriculture outside the city grow plants as crops such as vegetables and fruits. Since crops grow better when the carbon dioxide assimilation action is promoted, various methods for promoting the carbon dioxide assimilation action of crops have been proposed (see, for example, Patent Document 1).
Patent Document 1 discloses a method for growing crops in which an aqueous solution of ammonium hydrogen carbonate is sprayed in the soil and the ammonium bicarbonate is absorbed from the roots of the crops to promote carbon dioxide assimilation.

Moreover, the high voltage generation part which pressure | voltage-rises the electricity from an alternating current power supply part and the electrode part which applies an electric potential to a plant from this high voltage generation part are provided.
The electrode part is inserted into the soil at the base of the plant.
The electrode part is attached to the trunk of the plant.
The electrode part includes a conductive part electrically connected to the high voltage generating part and a cover part surrounding the conductive part so that the conductive part is insulated from the outside.
Moreover, the plant carbon assimilation promoting method according to the present invention applies a negative potential of -2000 to -6000 V to the soil at the root of the plant or the trunk of the plant.

The plant carbon dioxide assimilation promoting device according to the first embodiment includes a power connector 5, a high voltage generation unit 1, an electrode unit 2, and wires (cords) 15 and 16. The power connector 5 is connected to, for example, a household 100V AC power source (outlet) 10.

  The high voltage generator 1 has a box-shaped casing, and has a function of boosting electricity from a home AC power source (outlet) 10 and converting it into direct current. As shown in FIG. 4, the high voltage generation unit 1 includes a high voltage transformer 7 and a rectification unit 8. The high voltage transformer 7 boosts electricity from the AC power supply unit 10, and the rectification unit 8 converts AC to DC. One of the two wires on the secondary side of the high-voltage transformer 7 is connected to the rectifying unit 8. Further, the wiring on the other side is led to the ground 11 through a protection circuit.

  The electrode part 2 is a part to which only a negative potential is applied from the high voltage generation part 1, and is installed in the soil M at the base of the plant P. The electrode unit 2 is connected to a wiring 16 extending from the rectifying unit 8 inside the box-shaped high voltage generating unit 1 to the outside of the high voltage generating unit 1. The potential difference between the negative potential applied to the electrode unit 2 and the ground 11 is set to -2000 to -6000V. As shown in FIG. 2, the electrode part 2 has a shape having a grip part 6 and a rod-like part 13 protruding from the grip part 6.

The results are shown in Table 5.
The experiment was performed by the following method. First, the whole plant P which installed the plant carbonic acid assimilation action promotion tool was covered with the plastic bag (capacity 70L). Next, filter paper (diameter 9 cm) into which 0.2 ml of 28% aqueous ammonia solution was dropped was placed in a plastic bag and the mouth was closed. Then, the ammonia concentration in the plastic bag after being allowed to stand for a predetermined time was measured using a detector tube “Ammonia No. 3M” manufactured by Gastec Corporation.
