Description

Plant Growth {A PLANT CULTIVATION APPARATUS}

The present invention relates to a plant grower, and more particularly, to a plant grower, which is provided in a lower part of a plant grower and generates water and microbubbles by electrolyzing water flowing in the pipe, thereby removing the scale or scale of the pipe, The present invention relates to a plant grower capable of providing sterile water containing bubbles.

Generally, a hydroxyl group generating device is installed in water such as a humidifier, an air purifier, etc., and the installed hydroxyl group generating device generates a low temperature plasma with electric energy by inducing a discharge between a negative electrode and a positive electrode by receiving a relatively stable low voltage DC power.

In other words, the hydroxyl group is a kind of oxygen anion-based substance made in a plasma state called solid matter, liquid, gas and the fourth ion substance, and is capable of sterilizing, disinfecting and decomposing existing substances more than twice as strong as ozone and chlorine , And is known to be a natural substance that is harmless to the human body.

The generated low-temperature plasma generates hydroxyl group (OH-) in the water to remove bacteria and green algae present in the water, prevent the propagation of germs in the water, sterilize the water to prevent secondary contamination due to water contamination, The present invention relates to a plant grower in which plants can be grown without being contaminated by germs, viruses, molds or the like by allowing microbubbles (minute bubbles) to be generated by varying the pore sizes of meshes when the mesh structure is used.

The hydroponic cultivation method used in plant cultivation such as general bean sprouts, host herbs, sprout vegetables, etc., mixes water and nutrients at an appropriate ratio to produce nutrients directly to the plant embryo or to supply nutrients through plant roots. It is circulated in time intervals so that it can be sprayed directly on the embryo or in contact with the plant roots.

At this time, the nutrient or water is contaminated by airborne germs, viruses, molds, etc., and the contaminated nutrient or water is contacted with the plant to infect the plant and obstruct the growth of the plant or necrotize the plant.

Especially, the soybean sprout bacterial rot is caused by Pseudomonas putida (Trevisan) Migula biovar. It is a disease that causes severe economic loss in the cultivation of bean sprouts by a bacterium. Brown spots appear on roots and hypocotyls about 4 ~ 5 days after germination. After 1 ~ 2 days, And spreads widely to become corrupt. Pseudomonas putida biovar. A is latent by byproduct bacteria, and during the cultivation of bean sprouts, the bean sprouts grow thickly, and the temperature becomes high. When the bean sprouts are not easily washed, the density is rapidly increased in the latter period of cultivation and due to the accumulation of toxic substances secreted by these bacteria, The disease is caused by a substance such as a toxin secreted by the induced bacteria during the growth.

As described above, the incidence of bacteria and the like that may occur in the course of cultivating a plant is currently mixed with a fungicide or a chemical agent, which is an agricultural chemical, in a nutrient solution or water, and plants are planted by spraying the plant.

Therefore, there is a need to improve this.

In addition, the present invention can improve the performance of water containing hydroxyl groups generated by electrolysis by including microbubbles again, thereby saving electric energy required for generating hydroxyl groups.

In addition, the nutrients mainly used for hydroponic cultivation are uneconomical because the nutrients are covalently bonded to each other over time and the utilization of nutrients is very low as 50% ~ 70% because the nutrient particles are large, Covalently linked nutrients are released into rivers, causing creeks and rivers.

Therefore, there is a need to improve this.

The present invention has been created by the above-mentioned necessity, and the nutrient solution flowing along the pipeline or the channel is separated into covalently bound nutrients by using the plasma principle to improve the utilization of the nutrients and lower the algae phenomenon of streams and rivers It has its purpose.
