Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a plant cultivation tunnel. This cultivation tunnel is suitable for cultivation of, for example, tomato, cucumber, kidney beans, corn, edamame, radish, onion, melon, watermelon and other vegetables.
[0002]
[Prior art]
2. Description of the Related Art Tunnel cultivation in which a growth space for cultivated plants above a cultivation floor is covered with a light-transmitting sheet to keep heat and protect the wind is known. In addition, a multi-cultivation method is known in which the surface of a cultivation floor is covered with a sheet to suppress the growth of weeds, to keep the root warm, to retain water, or to block water. Multi-tunnel cultivation, which is a combination of tunnel cultivation and mulch cultivation, that is, multi-tunnel cultivation, in which the surface of a cultivation floor is covered with a multi-sheet and the growth space of cultivated plants above the cultivation floor is covered with a translucent sheet, is also known.
[0003]
According to the multi-tunnel cultivation, the germination, rooting and growth of the cultivated plant are good if the moisture in the cultivation bed is properly maintained and the temperature in the tunnel is properly controlled.
[0004]
[Problems to be solved by the invention]
However, if the soil in the soil is low when the cultivation floor is covered with a multi-sheet, sufficient watering and then covering with a multi-sheet, or after the cultivation tunnel is completed, spray a large amount of water on the ground outside the cultivation tunnel Watering (water supply) is troublesome, such as waiting for the water to penetrate the cultivation floor in the tunnel, or partially opening the tunnel and inserting a shower head there.
[0005]
On the other hand, the temperature in the tunnel rises rapidly due to the sun's direct sunlight in good weather.Therefore, ventilation is attempted with the outside air by opening a round hole in the tunnel sheet or turning up the tunnel sheet partially, etc. In some cases, the temperature inside the tunnel decreases due to the cold at night, so the vent opening opened during the day may need to be closed.
[0006]
Especially in early spring and late autumn, the direct sunlight in the daytime is relatively strong, and the temperature inside the tunnel will be too high unless ventilation with the outside air occurs.However, the outside air temperature drops sharply at night, and the tunnel is closed. Also, the temperature inside the tunnel is greatly reduced, and if ventilation with the outside air is performed, the temperature is further greatly reduced, and the cultivation floor is completely cooled. Therefore, without careful management, the cultivated plants may wither in the daytime due to high temperatures or may be frosted at night.
[0007]
An object of the present invention is to provide a cultivation tunnel that can suppress damage to cultivated plants due to such daytime and nighttime environmental changes.
[0008]
[Means for Solving the Problems]
(1) a cultivation floor sheet (2) that covers the surface of the cultivation floor and has many holes (2a to 2f) through which cultivated plants can pass;
A translucent tunnel sheet (4) above the sheet (2) and covering a space where cultivated plants grow;
A watering tube (5) arranged on the cultivation floor sheet (2) and capable of jetting a multi-stream of fine water impinging on the inner surface of the tunnel sheet (4) by water supply;
Cultivation tunnel equipped with.
[0009]
In addition, in order to facilitate understanding, the reference numerals of the corresponding elements of the embodiment shown in the drawings and described later are added for reference as examples in parentheses. The same applies to the following.
[0010]
According to this, when it is necessary to water the water, it is sufficient to supply the water to the watering tube (5).
[0011]
When the temperature in the tunnel rises due to strong direct sunlight during the day, water is supplied to the watering tube (5). As a result, multiple streams of fine water jet from the watering tube (5) toward the inner surface of the tunnel sheet (4) and collide with the tunnel sheet. By this collision, the fountain is sprayed and scattered, and falls on the cultivation floor sheet (2), that is, the multi-sheet, and penetrates the cultivation floor through the holes (2a to 2f). Some of the spray penetrates the cultivation floor after passing through the tunnel sheet. In addition to supplying water to the cultivated plants, the spray water removes the heat of the air in the tunnel, the heat of the tunnel sheet, and the heat of the surface of the multi-sheet and transports it to the cultivation floor. That is, the inside of the tunnel is cooled and heat is stored in the cultivation floor.
[0012]
Since the tunnel is cooled by the water sprinkling in this way, when the direct sunlight in the daytime is strong, the opening for ventilating the outside air should be minimized. Although the outside air temperature drops at night, the cultivation floor directly below the multi-sheet has water warmed by daytime watering, which keeps the inside of the tunnel warm. The multi-seat suppresses heat dissipation, so the nighttime warming effect lasts longer. In the daytime, the opening for measuring the ventilation with the outside air is minimized as much as the tunnel is cooled by watering, so that at night the heat radiation from the opening is small and the temperature drop of the tunnel is small. Therefore, the measures against the decrease in the nighttime outside air temperature become easy because the number of openings for measuring the ventilation with the outside air is reduced. The likelihood of inadvertent frosting is reduced.
[0013]
[Embodiment of the invention]
(2) The watering tube (5) extends in the longitudinal direction (y) of the cultivation bed and is substantially at the center of the width of the cultivation bed orthogonal to the longitudinal direction; 2a to 2f) are distributed in six rows parallel to the watering tube (5) in three rows each on the left and right of the watering tube; the cultivation tunnel according to (1) above (FIG. 1).
[0014]
According to this, the dimensions (width and height) of the tunnel can be made small with extremely high wind resistance. Further, it is possible to perform sufficient watering and water cooling with low pressure water supply using the small watering tube (5).
[0015]
(3) The watering tube (5) extends in the longitudinal direction (y) of the cultivation bed; a number of holes (2a to 2g) through which the cultivated plant can pass are arranged in seven rows parallel to the watering tube (5). Distributed; the watering tube (5) is between the 3rd row group and the 4th row group; the cultivation tunnel according to (1) above ((a) in FIG. 2).
[0016]
According to this, the tunnel dimensions (width and height) can be made slightly smaller with high wind resistance. If the water supply pressure in the watering tube (5) is slightly increased, sufficient watering and watering cooling can be achieved.
[0017]
(4) The watering tube (5) extends in the longitudinal direction (y) of the cultivation bed and is substantially at the center of the width of the cultivation bed orthogonal to the longitudinal direction; 2a to 2h) are distributed in eight rows parallel to the watering tube (5) in four rows each on the left and right of the watering tube; the cultivation tunnel described in (1) above ((b) in FIG. 2).
[0018]
According to this, the amount of cultivated plants in one tunnel can be increased. However, the tunnel dimensions (width and height) are slightly larger. If the water supply pressure to the water spray tube (5) is increased, sufficient water spray and water spray cooling can be achieved.
[0019]
(5) The cultivation tunnel according to any one of (1) to (4), wherein the large number of holes (2a to 2f) through which the cultivated plant can pass are distributed in a staggered arrangement on the cultivation floor sheet (2).
[0020]
Depending on the crop, one of the two adjacent rows may be left empty, or the crop may be planted in the central row of three rows and not in the two rows on either side. The hole where no crop is planted collects sprinkling water and uniformly penetrates the cultivation bed (1), whereby the cultivation bed (1) has an effect of uniform moisture and uniform heat retention.
[0021]
Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.
[0022]
【Example】
FIG. 1A shows an embodiment of the present invention. A black multi-sheet 2 having a large number of planting holes 2a to 2f covers the surface of the cultivated floor soil 1 in which the field is leveled and ridged. A translucent tunnel sheet 4 supported by aggregates 3a and 3b bent in an inverted U-shape is buried in the soil (covering the soil) on both side edges in the same manner as the edges of the multi-sheet 2. , Forming a kamaboko-shaped tunnel. A watering tube 5 is placed on the multi-sheet 2 at the center of the width thereof.
[0023]
FIG. 1B does not show the cultivated plants, and shows the distribution of a large number of planted holes 2a to 2f of the multi-sheet 2 shown in FIG. In this embodiment, six rows of planting holes 2a to 2f extending in the longitudinal direction y of the tunnel are formed in the multi-sheet 2, and a watering tube 5 is provided between three rows on the right and three rows on the left.
[0024]
The sprinkling tube 5 is a flexible resin or rubber band sheet for the upper half in which a large number of four fountain holes (points) 5a to 5d extending in the longitudinal direction y are provided. A flexible resin or rubber band sheet for a lower half body with a belt lining is fixed at an edge portion to form a flat hollow hose which expands in a tubular shape when water is supplied. Before being placed on the multi-sheet 2, it is spirally wound in a flat shape. When it is arranged on the multi-seat 2 as shown in FIG. 1, the spiral is rolled so as to roll the tire wheel and straightened. When collecting from the tunnel, roll up in a spiral. Thereby, arrangement, collection, transportation, storage, etc. on the multi-seat 2 are easy.
[0025]
(A) of FIG. 1 shows that the surface of the cultivated floor soil 1 in which the field is leveled and ridged is covered with a black multi-sheet 2 having a large number of planting holes 2a to 2f, and then the area under each planting hole is covered. Before or after sowing, the seeds of the corn were buried in the soil, and the watering tube 5 was rewound and straightly arranged with the watering hole facing upward, and then bent into an inverted U-shape. A translucent tunnel sheet 4 supported by aggregates 3a and 3b is laid, and a proper amount of water is sprinkled.
[0026]
By spraying the water during the day when the temperature in the tunnel was high, the temperature of the cultivated bed soil 1 was high at night, and the germination and growth of the corn were fast. At the time of watering, the handle of the valve for supplying water to the watering tube 5 is gradually turned to gradually increase the water supply amount (water pressure) to the watering tube 5, and the fountains 6a to gushing out from each of the many water fountain holes 5a to 5d. When 6d collides with the tunnel sheet 4 and the sound of spraying is generated, the increase of the water supply is stopped there, the state is continued for an appropriate time, and when the water content of the cultivated floor soil 1 becomes sufficient, watering is started. I stopped. If the temperature did not drop to an appropriate temperature by this watering, a minimum number of round holes were made in the tunnel sheet 4.
[0027]
In FIG. 1A, the fountains 6a to 6d are shown as being spouted at one location in the longitudinal direction y of the watering tube 5, but when watering, the same applies over the entire length of the watering tube 5. Spouts.
[0028]
After that, when the temperature does not decrease to an appropriate level even by watering, a further round hole is made in the tunnel sheet 4. Then, when the outside temperature at night becomes a temperature suitable for growing the corn, the top of the tunnel sheet 4 is opened or the tunnel sheet 4 is removed over the entire length in the longitudinal direction, and the cone grows above the tunnel. To facilitate.
[0029]
Since the tunnel sheet 4 is fanned by the strong wind, the smaller the tunnel size, the easier it is to increase the wind resistance. However, the amount of cultivated plants in one tunnel is small.
[0030]
According to the design of the present inventors, the cultivation of tomato, cucumber, green beans, corn, green soybeans, radish, onions, melons, watermelons and other vegetables is limited to the six rows of planting holes shown in FIG. In the case of the seven rows of planted holes shown in FIG. 2A and the eight rows of planted holes shown in FIG. 2B, a cultivation tunnel having high wind resistance and sufficient sprinkling cooling can be realized. . In each of the examples, the planting holes are arranged in a staggered arrangement in which one of two adjacent rows has the other hole at an intermediate position of the hole distribution in the y direction. Depending on the crop, one of the two adjacent rows may be empty, or the crop may be planted in the middle row of the three adjacent rows and not in both rows. The holes where no crops are planted collect water sprinkles and evenly infiltrate the cultivation floor soil 1, whereby there is an effect that the moisture of the cultivation floor soil 1 is uniform and the heat retention is also uniform.
