Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a hydroponic cultivation method that eliminates the need for planting seedlings that have germinated and grown in a seedling box.

(Prior art) In the current hydroponic culture, as shown in Figure 1 A, seeds are sown in bulk or one or several seeds at a time on urethane B placed in a nursery box A, and after the seeds germinate and grow. Cut urethane B into appropriate sizes as shown by the imaginary lines at the opening in Figure 1,
After that, seedlings C are planted in the through holes Da of a planting board made of urethane B and Styrofoam, and the planting board is placed in a hydroponic cultivation bed E as shown in Figure 2A, or in a hydroponic cultivation water tank. F
It is floated in water or liquid fertilizer W.

(Problems with the prior art) However, this method is troublesome in that it requires planting the germinated seedlings C onto planting boards.
Therefore, there is a problem in that the production cost becomes high.

In addition, if the urethane B has cuts for cutting, the roots of the plants that have sprouted and grown at the boundaries of the blocks may be cut off when the blocks are separated. The growth of plants whose roots have been cut is slower than those whose roots have not been cut, so there is variation in growth between those that have sprouted in the center of the block and the roots have not been cut, and those that have sprouted and grown at the border and had their roots cut. There are also disadvantages that occur.

(Object of the invention) In order to solve the problems of conventional hydroponic cultivation, the present invention uses a cultivation container that combines a seedling raising box A and a planting board, and installs it in a hydroponic cultivation bed. This eliminates the need to plant seedlings one by one by floating them in water or liquid fertilizer in a hydroponic cultivation tank.

(Structure of the Invention) As shown in FIGS. 3 to 7, the present invention comprises a large number of small chambers 1, each having an opening 3 formed at the bottom 2 through which plant roots extend. 2, a cultivation container 5 in which a soil substitute 4 such as urethane is directly or directly laid is used, and seeds are sown in the soil substitute 4 of this cultivation container 5 to germinate and grow. Plants growing on the soil substitute 4 in the small chamber 1 can be cultivated by placing it on a hydroponic cultivation bed E or floating it on water in a hydroponic cultivation tank F or liquid fertilizer W. .

The cultivation container 5 is molded from styrofoam or other suitable plastic material, and has small chambers 1 partitioned by partition walls 7 formed integrally with the inner side of a peripheral wall 6.

Various structures are possible for the opening 3 of each small chamber l, but -
As an example, in the case shown in FIG. 4, the bottom 2 is connected to the peripheral wall 6 of the cultivation container 5.
It is formed into a thinner wall than the partition wall 7, and has a number of through holes in its bottom 2, which serve as openings 3, from which roots of plants can grow.

In the case shown in FIGS. 5 and 7, the center part of the bottom 2 of each small chamber 1 is cut out and that part is used as the opening 3.

In the case shown in FIG. 6, the bottom 2 of each chamber 1 is cut out and a net 8 is placed over that part so that the roots of the plants can grow out from the mesh 9 of the net.

As the soil substitute 4, urethane or other suitable material suitable for growing plants is used.

-1- The soil substitute 4 can be placed on a net 8 provided on the bottom 2 of the cultivation container 5 as shown in FIG. 6, or a thin wall formed separately from the cultivation container 5 as shown in FIGS. The auxiliary container 10 may be laid inside the plastic auxiliary container 10, and the periphery 11 of the auxiliary container 10 may be locked to the receiving edge 12 of the bottom 2 of the cultivation container 5, thereby indirectly laying it on the bottom surface 2 of the cultivation container 5. Note that a large number of through holes 14 are opened in the bottom 13 of the auxiliary container IO.

When the soil substitute 4 is placed in the auxiliary container 10 as shown in Figures 5 and 7, the soil substitute 4 is placed as shown in Figure 8.
Seeds 15 are sown in the seed set 18, and a net, non-woven fabric, film, etc. 17 for preventing the seeds from shifting is placed over the seed set 18. They may be stored in each small chamber 1 and allowed to germinate and grow in the soil substitute 4 in the auxiliary container 10.

To germinate seeds sown in soil substitute 4, a small chamber l
After seeds are sown in the soil substitute 4 inside the container, the cultivation container 5 may be placed in a germination chamber for germination.

(Effects of the Invention) The present invention as described above has the following various effects.

(1) Since a large number of small chambers l are formed in the cultivation container 5, seeds can be sown in each small chamber l, and since an opening 3 is formed in the width 2 of each small chamber l, seedlings that have been germinated and grown can be grown. The roots are exposed to water or liquid from the hydroponic cultivation device through its opening 3! Since the seedlings grow into the W and absorb nutrients necessary for growth, there is no need to plant the sprouted seedlings in the soil substitute 4.

(2) Since there is no need to plant the seedlings, there is no need to worry about the trouble of planting the seedlings, and as a result, less labor is required, resulting in a significant cost reduction.

(3) Unlike the conventional method shown in FIGS. 1 and 2, there is no need to separate urethane B for planting.

Unlike when urethane B is cut off, the plant roots are not cut, so there is no variation in plant growth.
