Description

  The present invention relates to a floor suitable for cultivating plants and a cultivation method suitable for using the floor.

  As a conventional plant cultivation floor, a first light-shielding sheet that has both light-shielding and root-penetrating properties is laminated on the surface of a support net that entangles the roots of the plant in a peelable manner, and the periphery of the support net is supported by a frame It is already known that a water retaining mat is laminated on the back surface of a support net.

  This is a useful thing which can extract a plant only by peeling a light shielding sheet after cultivation of a plant.

JP 2010-88314 A

  However, the plant cultivation floor has no idea of reusing the light-shielding sheet after plant cultivation, and describes that another light-shielding sheet is used again on the support net.

  In addition, once the shading sheet is peeled off, the roots of the plant are peeled off from the support net and the water retaining mat, so when trying to cultivate the plant again using the same water retaining mat, the shading sheet cannot be reused, resulting in high costs. In addition to this, it takes time to plant a new plant on a new light-shielding sheet, and the inventor will have the same cultivation period, labor, and harvest as when using a new water-retaining mat. Noticed. More specifically, in the above cultivation method, a plant is placed on the first light-shielding sheet, and after the roots are entangled through the first light-shielding sheet and the support net therebelow, a plant cultivation floor is set up. Although it grows up, if a 1st light shielding sheet is peeled, a root will also peel from a support net | network.

  The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a plant cultivation floor and a plant cultivation method that can be reused as much as possible, can shorten the cultivation period, and can reduce labor. In addition, if possible, one of the purposes is to allow for an increase in yield.

  The present invention provides a plant cultivation floor in which a water retention mat is laminated on the back surface of a support net, and the periphery of the support net and the water retention mat is supported by a frame, and a recess is formed on the surface side of the water retention mat. A plant accommodation space is formed by the recess.

  The support net may be any material. However, in order to prevent breakage when cutting a plant protruding from the surface of the support net, it is desirable to do the following. That is, the support net is made of metal.

  Moreover, the plant should just be reproducible. Desirably, the plant is a moss plant.

  Furthermore, the suitable plant cultivation method using the cultivation floor for plants mentioned above is as follows. That is, using a plant cultivation floor, the plant is projected from the surface of the support net by cultivating the plant in a state where the plant is housed in the recess, and the projecting portion is cut and harvested, and the plant cultivation floor after cutting is obtained. It is to make the plant which remained in the recessed part by projecting again using the surface of a support net again.

  Moreover, when performing the above-mentioned plant cultivation method, it is more desirable as a growing environment that the plant is entangled with the water retention mat because moisture is easily supplied to the plant. Further, impurities produced from plants by cultivation tend to contaminate the water retention mat and the like, and a dirty water retention mat or the like is not desirable for growing plants. In order to prevent this, it is desirable that the impurities flow down naturally. In order to combine these, it is desirable to do the following. In other words, using a plant cultivation floor, the plant cultivation floor is laid sideways in a state where the plant is accommodated in the recess, and the plant cultivation floor is erected after the plant root is entangled with the water retention mat. Then, the plant protrudes from the surface of the support net, and the protruding part is cut and harvested, and the plant cultivation floor after cutting is cultivated and re-grown so that the plant remaining in the recess protrudes again from the surface of the support net. It is to let you.

  Furthermore, when harvesting a plant, there is a method of cutting off the plant coming out from the surface of the support net with a straw or the like, but in order to facilitate the harvesting operation, it is desirable to do as follows. That is, by cutting the cutting board while rubbing the surface of the support net, the plant protruding from the surface of the support net is cut off.

  According to the present invention, since the plant accommodation space is formed by the concave portion formed on the surface side of the water retention mat and the support net covering the surface side, the plant protruding from the surface of the support net is cut and harvested. Even so, plants remain in the plant accommodation space. And since the roots are already entangled in the water retention mat, the water absorption efficiency of the plants remaining in the plant accommodation space is better than when planted in the recess for the first time. Therefore, by cultivating a plant as it is using the plant cultivation floor, the labor for planting can be saved, the labor amount can be reduced, and the period for entwining the root can be eliminated, thereby shortening the cultivation period. In addition, the plant cultivation floor is excellent because it can be reused as it is.

  Moreover, if the support net is made of metal, the support net is less likely to be damaged even when the cutting board moves while rubbing the surface of the support net when cutting the plant protruding from the surface of the support net, compared to the resin. . In addition, the harvesting operation is easy because it is only necessary to move the cutting board as compared with the method of cutting off the plants protruding from the surface of the support net with a scissors or the like.

  And this plant cultivation floor is suitable for what can be regenerated like a moss plant.

  Also, if the roots of the plants are laid sideways until they are entangled with the water retention mat, and then cultivated with the water retention mat standing after entanglement, the growth will be promoted, and the impurities produced from the plants will flow down naturally, This is an ideal training environment. In particular, when the plant cultivation floor is repeatedly used twice or three times, an experimental result has been obtained that the yield increases more than the first time.

It is explanatory drawing which shows the plant cultivation method of this invention. It is a graph which shows the experimental result which confirmed the yield with the plant cultivation method of this invention.

  As shown in FIGS. 1 to 3, the plant cultivation floor 1 is laminated in order on the frame 2, the support net 3 stretched in a state of closing the opening of the frame 2, and the back surface of the support net 3. The water retaining mat 4 and the light shielding sheet 5 and the sheet presser 6 for fixing the water retaining mat 4 and the light shielding sheet 5 to the back surface of the support net 3 are configured. That is, the plant cultivation floor 1 has a three-layer laminated structure including the support net 3 and the water retaining mat 4 and the outer peripheral edge thereof is reinforced by the frame body 2. Hereinafter, each component will be described in detail.

  The frame 2 is formed by assembling the upper and lower, left and right ridges into a rectangular shape, and a concave groove 2a into which the sheet presser 6 is fitted is continuously provided on the rear surface over the entire circumference of the rectangle. The frame 2 uses an aluminum alloy as an example of a material.

  The support net 3 is grown while passing a plant through the mesh. Specifically, the support net 3 is a metal net, and stainless steel is used as an example of a metal. The size of the mesh partitioned vertically and horizontally is a square having one side of 1.6 to 2.4 mm.

  The water retaining mat 4 can store a larger amount of moisture than the light shielding sheet 5, and polyurethane (polyurethane with open cell sponge rich in water absorption) is used as an example of the material. Specifically, the thickness is set to 2 to 4 mm, and concave portions 4a are formed in places on the surface side. The concave portion 4a does not penetrate the back surface, that is, has a bottom structure, and a plant can be placed on the bottom. And the plant accommodation space is formed by the recessed part 4a and the support net 3 which covers the upper part of the recessed part 4a.

  The light-shielding sheet 5 has both a light-shielding property that prevents light from being applied to the back surface of the water-retaining mat 4 as much as possible and a water-retaining property that is moistened with moisture. Polyester is used as an example of the material. Specifically, it is a colored (black) non-woven fabric having a thickness of 0.17 to 0.24 mm. The light-shielding sheet 5 is simply placed on the back surface of the water retaining mat 4, is peelable, and forms the back layer of the plant cultivation floor 1 composed of three layers.

  The sheet presser 6 is a belt-like thing with elasticity. By press-fitting the sheet presser 6 into the concave groove 2 a of the frame body 2, the edges of the support net 3, the water retaining mat 4 and the light shielding sheet 5 are collectively fastened to the frame body 2.

  The above-mentioned plant cultivation floor 1 is generally suitable for plants grown with a small amount of water, and is preferably used for moss plants, more specifically for genus moss.

The plant cultivation method using the plant cultivation floor 1 described above is as follows. FIG. 4 shows an outline thereof.
(1) The operator sequentially superimposes the light shielding sheet 5 and the water retaining mat 4 on a flat table or the like, and places an appropriate amount of mushrooms in the recess 4a of the water retaining mat 4. Next, the support net 3 is placed on the water retaining mat 4 and the mushrooms are accommodated in the recesses 4a. In this state, the frame 2 is placed on the water retaining mat 4 on which these are laminated, and the light shielding sheet 5 A sheet presser 6 is press-fitted into the groove 2a of the frame 2 from the back side of the frame 2 to create an integrated plant cultivation floor 1.
(2) Hold this plant cultivation floor 1 in a horizontal state (horizontal state), sprinkle as much as necessary, and shine light from illumination arranged in the surroundings. In such a growing environment, the plant cultivation floor 1 is placed for about several weeks. As a result, the root of the moss (temporary root) enters the water retaining mat 4. In this way, when the temporary roots of the mushrooms enter the water retention mat 4, even if the plant cultivation floor 1 is set up vertically, sufficient water is given to the mushrooms from the water retention mat 4.
(3) Subsequently, the plant cultivation floor 1 is erected and cultivated in a state of being hung under a suspension member (not shown). In the example of illustration, it has suspended so that the back side of the two cultivation beds 1 for plants may be piled up. Then, in this cultivating environment, water is applied in an amount appropriate for the degree of growth, and light is applied.
(4) The mushroom is sufficiently grown in the growing environment, and the mushroom is protruded from the support net 3. By sprinkling water in a suspended state, water that could not be absorbed by the water retention mat 4 at the time of sprinkling naturally flows down impurities produced from the plant, so it can be said to be an ideal breeding environment.
(5) In order to harvest mushrooms protruding from the support net 3, the mushrooms of the protruding portions are recovered by moving the flat spatula as the cutting plate 7 while pressing against the surface of the support net 3.
(6) Since mushrooms remain in the recess 4a of the water retaining mat 4, the plant cultivation floor 1 is set up as it is, and reused and cultivated in a state suspended from above. That is, the process returns to (3). Thereafter, (3) to (5) are repeated.

  As an example of the genus mushroom used in the above (1), there is the following. A growth condition in which a sterile nutrient medium of 1.3% agar concentration called M51C is laid on a petri dish having a diameter of 9 cm, and a genus genus mushroom is placed thereon is used. Gemma generated from a single progenitor cell in a goblet grown under a continuous white light irradiation environment and collected after becoming a young frond. Moreover, you may plant the collect | recovered mushrooms in the recessed part 4a of the new water retention mat 4, and create the new cultivation bed 1 for plants.

  The graph of FIG. 5 shows the experimental results of harvesting genus Mosswort three times with the plant cultivation method described above. The increasing rate on the vertical axis represents the harvested weight in% with respect to the weight of the first mushroom planted in the recess 4a. The number of times on the horizontal axis represents the number of harvests. The interval from planting to the first harvest, and the interval from the first to the second and the second to the third harvest are about 7 weeks each. is there. Although the rate of increase in the first crop is about 15%, the second crop is less than 40% and the third crop is 180%. Compared to the first time, the increase in the yield of the second and third crops is presumed to be due to the breeding of common moss and growth points in addition to the planted parts. Therefore, it is presumed that a stable yield can be obtained if a growing environment is prepared.

  The present invention is not limited to the above embodiment. For example, the shape and thickness of the plant cultivation floor 1 can be changed as appropriate.
