Description

Electrostatic spray plant grower {ELECTROSTATIC SPRAY TYPE CULTIVATOR FOR PLANT}

The present invention relates to an electrostatic spray plant grower, and relates to an electrostatic spray plant grower capable of spraying water or a nutrient solution to plant seeds in the form of a mist.

In general, hydroponic cultivation is in the limelight due to the growth rate of plants and the convenience of pest prevention and management. Hydroponic cultivation is a method of cultivating terrestrial plants by submerging them in a nutrient solution without soil, and is recognized as an innovative method because it can be grown even without soil essential for the growth of crops. Since such hydroponic cultivation supplies nutrients through a nutrient solution, plants can efficiently absorb nutrients, thereby promoting growth. However, in such hydroponics, air cannot be smoothly supplied as the roots are submerged in the nutrient solution.

Recently, aerophonics, which grow plants by hanging them in the air, have been popularized to solve the above-mentioned disadvantages of hydroponic cultivation. Aerophonic is a method of growing by spraying water and nutrients to the roots of plants suspended in the air with a sprayer. Since the roots are exposed to the air and can be sufficiently supplied with oxygen, they can absorb nutrients smoothly.

Due to this density, the sub-layer 43 is formed less densely than the main layer 40 . Thus, the sub layer 43 provides air to the lower part of the main layer 40 through the pores.

For example, the aforementioned main layer 40 has a thickness of 1.5 mm and a weight (density) of 200 g/cm ³ , and the aforementioned sub layer 43 has a thickness of 15 mm and a weight (density) of 200 g/cm ^{3 .} ) can be configured.
