Abstract

PROBLEM TO BE SOLVED: To provide hydroponics by which cultivation can be carried out even in a land unsuitable for farming in agriculture without selecting the land, plants unadapted for continuous cropping can continuously be cultivated, the quality and yield can freely be obtained by controlling the culture liquid and year-round culture can be performed with light labors. SOLUTION: Cultivation grooves and grooves for supplying a liquid and discharge the liquid are installed at the base of a cultivation tank and the grooves are used as a pool for stabilizing the liquid supply and circulation of the culture liquid and the amount of the supplied liquid. The nutrient and water are supplied from the grooves to roots of crops utilizing capillary actions of a nonwoven fabric 4 by using the nonwoven fabric 4 and a root penetration preventing sheet 3 without using a liquid supply tube for the nutrient and water to the crops.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying a culture solution, a reserve tank,
An invention related to a cultivation ditch and a cultivation tank that functions including a planting panel and circulation.

[0002]

2. Description of the Related Art Conventionally, nutrient solution cultivation is mainly a system of a combination of a tube, a pouring pond, a solution and rock wool, a lightweight soil, a rice husk, and the like, but each method has a structure that has advantages and disadvantages. Met.

[0003]

Therefore, there are the following drawbacks. A. Since the tube feed dissolves and flows fertilizer in water, it tends to be clogged due to the formation of dust, blue glue, etc. during long-term use. (B) It is inconvenient to adjust the EC etc. to the situation of the produced crop due to the change of weather due to the large amount of circulation and the amount of the solution. C. In the planting panels, etc., the culture solution has changed because it is a reserve tank, and depending on the long-term cultivated crops,
Three replacements are required, which does not result in energy saving and low cost. D. Equipment that takes in a large amount of oxygen into the culture is required. E. It is difficult to control the culture solution for cultivated crops, and it is difficult to produce high-quality crops.

[0004]

Means for Solving the Problems In order to supply liquid without using a liquid supply tube, a planting panel was invented.
A groove for waste liquid is provided, an optional small weir is provided in the middle, a large number of small reservoirs are created, the capillary action of the nonwoven fabric is used, and the root is constantly exposed to high humidity while maintaining high humidity at the root. Therefore, we decided to absorb oxygen in the air.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. The planting panel 7 of the present invention shown in FIG. 1 is installed at an arbitrary slope. There is a groove and a weir is provided at an arbitrary position. A hydroponic sheet 5 for waterproofing is laid there, and a nonwoven fabric 4 of a capillary action is laid thereon, and the root sheet 3 is bridged on the groove. When the culture solution is sufficiently contained in the non-woven fabric 4, the upper panel 2 is put on the non-woven fabric 4 and the aluminum deposition poly film 1 for light-cutting heat is applied. And make a hole in the planting hole in the upper panel with a knife or the like in the polyfilm to plant the production crop.

FIG. 2 is a side sectional view of the present invention.

FIG. 3 is a perspective view of a multi-groove according to the present invention.

[0007]

The roots of capillar hydroponics grow in the air near 100% humidity, so that the roots can absorb oxygen in the air and absorb the culture solution from the bottom into a thick nonwoven fabric that has the property of absorbing water. By simplifying the equipment for supplying nutrients and moisture to the roots on the root-prevention sheet, the running costs such as material costs, culture solution, etc., can be greatly reduced, resulting in energy saving and low cost.

Claims (2)

[Claims] A cultivation ditch and a bottom of a cultivation tank are provided with a liquid supply and waste liquid groove, and this groove is used as a pool for stabilizing and supplying a liquid supply and a culture liquid supply. Hydroponic cultivation that uses a nonwoven fabric and a root-preventing sheet from the groove instead of using a liquid tube, and uses the capillary action of the nonwoven fabric to supply nutrient water to the roots of the crop. 2. In order to secure a liquid supply amount in the groove, small weirs are provided at arbitrary intervals to pool the culture solution and supply nutrient water to the crop without interruption. The shape of the groove is round, square, or polygonal. Etc. can be used alone or in combination, the width can be provided in any width, the number can be used alone or in combination, the depth can be
Set an arbitrary depth in consideration of the width and number, the height of the weir is shaped,
Nutrition cultivation that sets an arbitrary height in consideration of width, number, and depth.
