Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a planting panel for hydroponic cultivation that is used for hydroponically cultivating vegetables such as Japanese cabbage, salad vegetables, leafy vegetables, tomatoes, and cucumbers.

(Conventional technology) Conventionally, when cultivating Japanese cabbage, salad vegetables, leafy vegetables, tomatoes, cucumbers, etc. hydroponically, cultivation beds with cross-sections are connected together and a vinyl sheet is placed on top of the cultivation beds. Create a channel and place Styrofoam planting panels in the channel. Each time the seedlings inserted into the cultivation holes of the planting panel via urethane grow and are harvested, the planting panel is disinfected, dried, and used repeatedly.

(Problem to be solved by the invention) When disinfecting the above-mentioned planting panels, it is possible to completely disinfect the planting panels by exposing them to heated steam or disinfecting gas one by one, but this takes a lot of time and effort. Therefore,
A method of sterilizing a large number of planting panels at the same time by stacking them one above the other or stacking them vertically, and inserting a rod or the like between each planting panel to create a gap through which heated steam or disinfectant gas can pass. is taken. However, there is still the problem that it is time consuming.

In addition, since the planting panels are made of styrofoam, the planting panels are removed from the molds at the manufacturing factory and still contain gases that can harm the cultivated vegetables.
This gas is released by leaving the planting panels in the natural environment for an extended period of time. However, at factories, the planted panels taken out of the mold are not left alone for long periods of time, but instead are immediately stacked in an appropriate number, wrapped in vinyl film, etc., and shipped. Wrapped planting panels have surfaces that are closely pressed together, which prevents outgassing. While the planting panels are packaged, internal gas emissions are prevented, so growers cannot unwrap them and use them immediately. Therefore, once unwrapped, the grower must leave gaps between each planting panel and wait for the gas to release.

The present invention improves conventional planting panels and provides a planting panel for hydroponic cultivation that can eliminate unnecessary labor and time when using new planting panels or repeatedly using already used planting panels. This is what I am trying to do.

(Means for Solving the Problems) The present invention has a structure in which a plurality of warts are protruded from the back surface (lower surface) of a Styrofoam planting panel. The warts are preferably provided close to the four corners of the panel surface, and if necessary, also provided in the middle of the long edges of the panel surface.

Further, the cross-sectional shape of the wart may be square, triangular, or circular.

(Functions and Effects) The planting panels of this invention have warts protruding from the back (bottom) surface, so even if the planting panels are stacked vertically or arranged horizontally or vertically, there will be a gap between each planting panel corresponding to the warts. can. Therefore, even if Styrofoam planting panels that have just been removed from the mold at the manufacturing plant are wrapped in layers, gas can be released from the planting panels, and by the time the grower unwraps them, time has passed and the planting The gas has already come out of the panel, so it can be used immediately. Also,
If you overlap the planting panels when disinfecting or drying them, gaps will naturally form, increasing work efficiency. In addition, the nutrient solution flowing along the sides of the nutrient solution flow path hits the warts and spreads out, which eliminates uneven growth of the seedlings.

(Example) An example of the present invention will be described below with reference to the drawings.
1 is a cultivation bed, 2 is a vinyl sheet, 3 is a planting panel, 4 is a cultivation hole, and 5 is a wart. Figure 2 shows the planting panels 3 stacked one above the other, with 6
is a gap. FIG. 3 shows the state of use.
FIG. 4 shows another embodiment in which six circular warts 5 are provided.
