Description

Three dimensional fertilizer for plants, plant culturing apparatus comprising the same and plant growth measuring system comrpsing the same}

The present invention relates to a three-dimensional fertilization device for plant cultivation, plant cultivation equipment including the same, and a plant growth measurement system including the same. More specifically, the present invention relates to a three-dimensional fertilization device for plant cultivation that enables supply of a nutrient solution containing fertilizer ingredients necessary for plant growth evenly and three-dimensionally from all directions centered on the roots of plants growing along the direction of gravity, and It relates to plant cultivation equipment including the above-mentioned three-dimensional fertilization device and a plant growth measurement system including the above-mentioned three-dimensional fertilization device.

Elements necessary for plant growth (hereinafter referred to as 'plant growth factors') include light, moisture, temperature, and nutrients.

Although temperature among the plant growth factors listed above affects plants through the atmosphere, the three plant growth factors excluding light affect plants through the soil where plants, especially plants with roots, grow.

Therefore, not only is it necessary to effectively and appropriately supply the elements necessary for plant growth through the soil, but it is also desirable to measure the relationship between these elements and plant growth through the soil.

In addition, the plant growth factor that is easy to artificially control and for which artificial control is most often performed is fertilization, that is, supplying nutrients, and for this purpose, a variety of fertilizers have been developed and sold and can be purchased and used commercially.

In particular, fertilization is mainly done by dispersing the solid form on the soil in which plants are planted, dissolving it in water, or supplying liquid fertilizer (this is called 'nutrient solution') to the soil in which plants are planted.

In the case of fertilization with a nutrient solution, as shown in Figure 1, it is spread on the ground and absorbed into the soil over time to gradually permeate downward, stay in the soil and allow the plant to absorb it through the roots, or otherwise, As shown in Figure 2, a water supply facility is buried in the ground, and the nutrient solution is supplied through this water supply facility. It is also absorbed into the soil over time and stays in the soil, allowing the plant to absorb it through its roots.

In Figure 1, the soil 11 in which the plant is planted is contained in the planting container 10 in which the plant is planted, and the state in which the plant 21 is planted in the soil 11 is shown in a side cross-sectional view, as an example. Typically, it shows fertilization by spraying the nutrient solution on the surface of the soil using a watering can (31).

In Figure 2, the soil 11 in which the plant is planted is contained in the planting container 10 in which the plant is planted, and the state in which the plant 21 is planted in the soil 11 is shown in a side cross-sectional view, as an example. It shows that the nutrient solution is supplied directly into the soil through a supply pipe (41) buried through the ground and a nozzle (42) installed on this supply pipe (41).

However, with this conventional fertilization method, a concentration gradient of the nutrient solution is bound to occur, which causes a difference in the distribution of the nutrient solution along the direction of gravity, and there is also a problem in that it is not effectively and sufficiently absorbed by the plants and a significant amount of the fertilized nutrient solution may be lost.

In addition, even if the plants are planted and managed in a certain planting container, there is a problem that it is difficult to confirm the optimal cultivation conditions for the plants by observing the growth of the plants, especially the growth of the plant roots.

That is, the three-dimensional fertilizing device 51 for plant cultivation according to the present invention has a fluid, that is, a nutrient solution flowing inside, in order to supply the nutrient solution supplied through a nutrient solution supply source three-dimensionally from all directions centered on the roots of the planted plants. It is formed as a hollow conduit 52 that extends downward in the direction of gravity centered on the roots of the plant and is installed to surround the roots of the plant.

The conduit 52 includes an underground buried portion 54 buried in the ground; and a first exposed portion 55 connected to one end of the underground buried portion 54.

The underground embedding part 54 may be formed to extend downward in the direction of gravity while surrounding the roots of the plant. By having this structure, the underground embedding part 54 can be formed from all directions around the roots of the plant planted in the center. It can ensure that the nutrient solution is supplied evenly.

One end of the first exposed part 55 may be connected to the underground burial part 54, and the other end may be connected to a nutrient solution supply part that supplies nutrient solution, as will be described later.
