Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plant cultivation device used in the field of cultivating crops using a rock wool medium in greenhouse horticulture.

[Conventional technology and its problems]

Conventionally, in greenhouse horticulture, crops are grown directly on a cultivator suitable for cultivating one crop (this is called a normal bed), and the roots of the crops are immersed, and the above-ground parts are supported with appropriate supports (such as dials and strings). At the very least, hydroponic cultivation must be carried out, etc., but it takes a lot of effort and money to carry in and manage the culture soil, keep the beds warm, or keep the space inside the facility warm. In addition to the need to pay attention to water distribution, there is a lack of oxygen in the culture medium, a large amount of money is required to heat and cool the bed or space within the facility, and to install a water tank. Recently, the use of rock wool culture medium has become popular in order to compensate for these disadvantages, but compared to soil, these have disadvantages such as the ability to spread heat through soil. There are problems with heating etc.
Consideration must also be given to the liquid supply.

In addition, the prior art of this extreme rock wool culture medium is:
JP-A-58-152416 and JP-A-59-74928
There are publications such as JP-A-59-120086, etc., but these are all about the manufacturing method of rock wool medium itself and the invention of the material, not cultivation devices using it. There is an unresolved problem with cultivation equipment that uses wool.

In addition, there is a utility model application publication number 150955/1983 as a technology for keeping the above-ground part warm that is similar to a strength-grip device. In addition to the above-mentioned disadvantages of hydroponics, this method uses a complicated water pillow-like heat retention mechanism, so it cannot be considered practical.

[Problem that the invention seeks to solve]

The present invention was developed as a result of extensive research and testing, focusing on soil heating (cooling in summer) and liquid supply means.

[Structure of the invention]

Hereinafter, this invention will be explained in detail based on the drawings.

FIG. 1 is a conceptual plan view of the overall side view (FIG. 4), and 1.1 is an appropriate size [type of crop, product i, or its cultivation form (only seedlings are raised until harvest) etc.), and after planting crops on the Rockwool medium fabric, it is covered with a synthetic resin film from the bottom to the top, or one of the girders is placed at appropriate intervals. They are placed in parallel or in a single row on a sheet 5 of synthetic resin, etc. spread in a field, cultivation area) or in a facility, and an elastic thin film 2' of synthetic resin of an appropriate size is placed in the middle or on the side. This is a cultivation device using a rock wool culture medium, in which these sets are installed in several rows within the facility 6, and these sets are connected and fixed using plastic binding fixing rods 9). - 4 in the same drawing is the space between each set, and this is the work space within the facility.

In addition, each of the rock wool culture media of the present invention is capable of carrying out the implementation described in claim (2) in order to supply liquid to the rock wool culture medium except when placed in a flooded area such as in a paddy field. As shown in section 1, the liquid supply branch pipe 9' connected to the main liquid supply pipe 7 is laid below the tact 2, and a rock wool culture blower B is installed therein.
In the winter, warm air is supplied to the duct 2 through the air pipes 8 to 8, but in the hot summer, the duct 2 can be cooled through cold air.

In addition, at a suitable place on the upper surface of the heat retention duct 2 of the present invention,...°
Ventilation 2. n is an appropriate number (as described later, holes of a size and number such that the holes 2 can maintain close contact with the rock wool medium on both sides or one side) are provided.

However, the seedlings P may be directly planted in the planting hole 1'' on the rock wool medium, but it is also possible to separately place the grown seedlings in a rock wool pot 1' and then plant them in the rock wool medium. can.

[For production]

Directly on rock wool medium or synthetic resin membrane lr
Make a planting hole 1# in a rock wool medium covered with water, and plant the desired crop P in that planting hole or in another small block of rock wool pot 1'' on top of that hole.
Air heated by the heater H is supplied to the duct 2 through the air pipe 3 and the branch pipe 8', causing it to expand and bring it into close contact with the rock wool culture medium 1 installed on both sides or one side, and at the same time, it is placed above the valley duct. Drill holes 2# at appropriate intervals and of appropriate size (i.e., to the extent that this duct maintains expansion in close contact with the rock wool medium on both sides or one side),
Hot air heated by a heater H is released into the space inside the house to warm the space inside the house.

In addition, liquid is supplied from a main liquid supply pipe 7 installed below the duct, and liquid is supplied from the rock wool culture medium to the rock wool culture medium through a liquid supply branch pipe 7'. = By doing this, during the cold winter, the rock wool medium 1.1 will be appropriately heated by the duct) 2 that is in close contact with it, and the ventilation port 2#
It is possible to discharge hot air or cold air (in summer) into the facility, which can be used for heating and cooling the facility.
The air conditioner can be heated and cooled again from the air intake.

In addition, Rockwool I medium receives moisture and nutrients from the liquid supply pipe to stimulate crop growth, and due to its nature, Rockwool medium can also supply appropriate air, making it more effective than conventional hydroponic culture. can be expected to have better growth.

Furthermore, it is a matter of course that in the present invention, the facility space installed according to the present invention can also be heated by obvious means in the same manner as in ordinary greenhouses and plastic greenhouses to increase the overall effectiveness and vermilion.

In addition, as mentioned above, in the duct 2 of the present invention.

During high temperatures in summer, cool air is supplied to grow Rockwool medium 1.
, 1 and also has the function of cooling the plants and enabling the growth of summer crops within the facility.

Compared to hydroponics, etc., there is no need to worry about the spread of diseases, and air can be maintained in the medium as needed.Furthermore, there are no facility costs like hydroponics or bench cultivation, and the handling is easy. It is also simple and can save labor.
