Description

[Detailed description of the invention] The purpose of the invention is to make the water depth of a hydroponic tank almost constant.

In conventional hydroponic tanks, the bed is one level, so when the tank is long, the bed is installed on a base as shown in Figure 1. For example, if the land is not level, the water depth in the tank is not constant. do not have.

Therefore, the flow of water in the hydroponic tank is poor and local stagnation tends to occur.

As a result, the growth of seedlings becomes uneven and the growth effect becomes poor.

The present invention aims to solve the above-mentioned drawbacks.

The present invention will be described below with reference to the embodiment shown in FIG.

1 is a box-shaped bed made of expanded polystyrene, and the bed is made up of bed units with an inverted and U-shaped cross section.
Connect -1', 1', 1'... one after another.

2. Use vinyl sheets to prevent water leakage inside the bed.

In this way, the lower bed is constructed.

Water 3 is poured into this lower bed to enable horizontal support of the upper bed 4.

The upper bed 4 may be a single box-shaped bed made of expanded polystyrene if it is small, but if it is large and long, the lower bed 1',
Similar to 1'..., the beds are made of expanded polystyrene, and the long ones have a face-shaped cross section 4', 4'...
... are connected one after another, a vinyl sheet 5 is placed over them, and water 6 is stored therein to form a hydroponic tank.

Reference numeral 7 is a styrofoam lid placed on the top of the hydroponic tank, and a hole 9 for planting is provided in the appropriate place, and seedlings 8 are placed in that area.
The method of planting is the same as in conventionally known hydroponic equipment.

As described above, this invention has a double bed structure, so when the upper hydroponic tank is floated on the water surface of the lower bed, the upper hydroponic tank is held horizontally, so there is no unevenness on the base surface. However, since the water depth in the upper hydroponic tank can be kept almost constant, the seedling-raising effect is good without causing any nurturing.

Also, since the lower bed is made of styrofoam, it can be easily cut with a saw, so depending on the size of the bed, you can cut the bed units appropriately and combine them as needed. It also has the effect that it can be easily and stably adapted to this, and a lower bed of an appropriate size can be set at any time and place.
