(40) The internal structure is preferably configured such that each fluid can be uniformly mixed.

Since the configuration of the mixer 40 for mixing and supplying various types of fluids is well known, a detailed description thereof will be omitted. However, the mixer 40 supplies only steam or hot water provided by the steam supply device 10, only high pressure air supplied from the air supply device 30, or the watering supply device 20. It is also possible to be configured to supply only the water supplied from the).

To this end, valves for controlling the supply of each fluid may be installed on the respective pipes connected to the mixer 40 in the steam supply device 10, the air supply device 30, and the water supply device 20. .

In addition, the method of supplying fluid into the soil S via the mixer 40 may include a method of mixing steam and air, a method of mixing water and air, a method of mixing steam and water, and the like. Can be made.

Reference numeral 45 denotes a pressure gauge for measuring the pressure of the mixer 40.

The steam supply device 10, the air supply device 30, the mixer 40, such as is installed on the outside of the soil (S), bar may be fixedly installed in a specific position, unlike the movable structure That is, it can be mounted and mounted together with the balance.

Next, the soil buried structure will be described with reference to FIGS. 2 and 3.

Perforated pipe 60 is a tube formed with a plurality of holes to discharge the fluid supplied through the fluid supply pipe 90 to the soil (S), so that the top of the soil, that is, even in a state covered with soil It is preferable to use a tube made of a material having rigidity. For example, a synthetic resin corrugated pipe or a metal pipe can be used.

The perforated tube 60 may be provided with a fixing member 63 to fix the position of the fluid supply pipe 90 therein. At this time, the fixing member 63 may be configured in various ways as long as it can support the fluid supply pipe 90 to be stably positioned in the hole pipe 60 while preventing the deformation of the hole pipe 60. For example, it can comprise with a board | plate material etc. of a disk-shaped structure.

When the fixing member 63 is installed, the fluid supply pipe 90 may be inserted together when the fluid supply pipe 90 is inserted into the oil hole 60.

The soil inflow preventing member 70 is installed for the purpose of preventing foreign substances such as soil S from being introduced into the perforated pipe 60, and a sheet structure made of a porous material may be used. For example, the nonwoven fabric may be used in such a manner as to cover the outside of the perforated tube 60 and then cover the top soil thereon.

The fluid supply pipe 90 is a pipe provided to inject steam or the like into the oil hole pipe 60, and is preferably connected to the mixer 40 through a connection pipe 50.

Since other configurations are the same as or similar to the configurations of the above-described embodiment of the present invention, the same reference numerals are given to the drawings, and repeated description thereof will be omitted.

It describes a crop cultivation method using a multi-purpose soil steam disinfection device according to the present invention as described above.

First, the excavation of the soil (S) is embedded in the perforated pipe 60, and after installing the soil inflow prevention member 70 on the perforated pipe 60, the perforated pipe 60 and the soil inflow prevention member 70 The soil is piled up and covered to a height where crops can be grown.

At this time, the fluid supply pipe 90 is inserted into and installed in the hole pipe 60 before or after covering the soil S on the hole pipe 60. Then, the mixer 40 connected to the steam supply device 10, the air supply device 30, the water supply device 20, and the like are connected to the fluid supply pipe 90 by using the connection pipe 50.

Next, the porous pipe 60 is installed by covering the vinyl or steam sheet and the water bag to enable steam disinfection of the soil (S) on the embedded soil (S). Of course, the periphery is preferably installed in a form that is fixed by pressing the soil (S) to minimize the escape of the heat source to the outside.

Next, steam is supplied to the fluid supply pipe 90 installed inside the oil hole pipe 60 using the steam supply device 10, the air supply device 30, and the mixer 40 to steam sterilize the soil S. do.

Then, planting crops, such as ginseng in the soil (S) has been steam sterilized.

During crop cultivation, crops can be grown while supplying air or water to the soil, ie underground.

That is, the air is supplied to the fluid supply pipe 90 by using the air supply device 30 and the mixer 40 to improve the physical properties of the soil S through underground air injection, or the underground water supply is It is to supply the water to the fluid supply pipe 90 by using the water supply 20 and the mixer 40 to be made.

The apparatus of the present invention and the crop cultivation method using the same as described above, can be usefully used to enable the cultivation of crops with severe disturbances due to cultivation characteristics such as ginseng. That is, after steam disinfection using the apparatus of the present invention on the soil (soil) on which crops such as ginseng have already been grown, it is possible to grind crops with severe disturbances such as ginseng by reworking.

Hereinafter, the specific implementation effects of the present invention will be described based on the actual test results.
