Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a warming cultivation device in a gardening facility.

(Prior Art) In horticultural agriculture in which vegetables and flowers are intensively cultivated, in order to meet a rapidly increasing demand, warm cultivation is carried out by densely planting in a greenhouse.

(Problems to be solved by the invention) However, heating cultivation in a greenhouse is conventionally performed on a cultivation bed formed on the ground. Therefore, when planting saplings such as strawberries and chrysanthemums densely and managing their growth condition, it is necessary to work for a long time in an unreasonable posture with the back bent. Problems were likely to occur on the surface.

Therefore, in order to eliminate the work in an unreasonable posture, it is possible to apply a cultivation bed with supporting legs and manage cultivation at an appropriate height. However, the heating means provided in the greenhouse is usually an air heating system, and since heat is propagated to the cultivation floor after the entire greenhouse has risen to a predetermined temperature,
Not only did it take a long time to reach the optimum temperature, but the heating cost increased, which greatly affected the cultivation cost. In addition, since the temperature inside the greenhouse is higher than the temperature in the deep part of the cultivation bed, the balance between the growth of roots such as vegetable and the growth of plant height is broken, resulting in long seedlings and weak crops, resulting in pest damage. On the other hand, although it is easy to be bitten by flowers, the leaf value of flowers and flowers becomes thin and the mesophyll becomes thin, resulting in a decline in commercial value and a large decrease in sales.

In view of the conventional circumstances as described above, the present invention enables the work to be done in a comfortable posture, and has a structure for efficiently and uniformly heating the roots of crops, thereby eliminating the above-mentioned conventional problems. It is an object of the present invention to provide a warming cultivation device designed to be eliminated.

(Means for Solving the Problems) The warming cultivation device of the present invention is a heat-insulating material and a heat accumulating material in order from the bottom inside the box body of the cultivation floor with legs in which the box body part is supported in the air by the supporting legs. Material and a waterproof film are laminated, an aqueous solution for culture is stored in this waterproof film, a heating pipe is arranged inside the heat insulating material in the vicinity of the heat storage material, and a liquid heat medium is placed in the heating pipe. A heating means for heating and circulating the supply is connected.

Further, rock wool is wrapped with a waterproof film placed on a heat storage material, these rock wools are impregnated with an aqueous solution for culture, and crops are planted on these rock wools.

Further, the heat insulating material is formed of a flat plate-shaped artificial pumice stone.

(Operation) Since the legged cultivation bed is formed at a height suitable for cultivation management, the worker can engage in the work in a comfortable posture.

In addition, the heat loss of the conduction heat supplied from the heating pipe is suppressed by the heat insulating material, and the cultivation floor itself has legs and the box part floats in the air. Since the air layer of the above works as a heat insulating layer, heat can be conducted efficiently without being deprived of heat by the ground.

Furthermore, this conduction heat is uniformly diffused through the heat storage material into the aqueous solution for culture stored in the waterproof membrane, so that heat conduction suitable for the growth of the crop is performed.

It is lightweight and has a heat diffusivity of 3 mm. It is formed so as to fit the inner shape of the box 2a by using a veneer plate or a synthetic resin plate of 10 mm or the like.

Further, as the heat insulating material 4, artificial pumice stones shown in FIGS. 6 and 7 (for example, the Hebel brand name manufactured by Asahi Kasei Co., Ltd.) may be used. The flat plate-shaped heat insulating material 4 made of artificial pumice shown in FIGS. 6 and 7 has one end surface 41 to the other end surface 42.
Pipe insertion holes 43 ...
Heating pipes 8 of 10 mmφ to 20 mmφ in which the heated heat medium 9 is circulated are inserted through these pipe insertion holes 43.

Further, as shown in FIG. 8, a plurality of rows of pipe embedding grooves 44 ... Are provided on one surface of the heat insulating material 4 made of artificial pumice from the one end surface 41 side toward the other end surface 42. The heating pipes 8 ... May be embedded in the embedding groove 44, and the heating pipes 8 may be covered with a flat plate member 50 made of artificial pumice stone, veneer plate, or synthetic resin.

The waterproof film 6 stores an aqueous solution, and is installed by folding it from the upper edge of the box 2a to the outside using a vinyl film or the like.

The aqueous solution 7 is stored in the waterproof film 6 to have a depth of 3 cm to 10 cm.
