[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional nursery basket, since the sides and bottom have a coarse grid pattern, the roots grow as the seedling grows, so the grown roots pass through the nursery basket grid. While it spreads out and is being laid and raised on the dedicated seedling raising bed, it is also entangled with the roots of other adjacent nursery raising baskets that have similarly passed through the seedling raising cage lattice, and are transplanted to the dedicated planting bed. On that occasion, there was a problem that the intertwined roots had to be unraveled. In addition, even if the roots that are entangled are unraveled, the seedling roots may spread too much to fit within the planting frame of the dedicated planting bed, which means that much time and labor must be spent on planting work. There is a solution problem.

Further, in general, the seedling-raising period is longer than the harvesting period because the initial growth after germination is very slow and requires a long period of time. Even if the dedicated planting bed is vacant, it is necessary to wait for the planting period depending on the growth condition of the seedlings, and during that time, the dedicated planting bed is not used and the efficiency of use of the dedicated planting bed deteriorates. There are also unsolved issues.

Therefore, the present invention has been made by paying attention to the above-mentioned unsolved problems of the related art, and by restricting the range of spreading the roots of the seedlings at the time of raising the seedlings, the transplantation can be easily performed and the planting The purpose of the present invention is to provide a nursery pot for hydroponic cultivation that can improve the utilization rate of equipment for hydroponic cultivation such as a dedicated bed.

[0007]

[Means for solving the problem]

 In order to achieve the above object, a nursery pot for hydroponic cultivation according to the present invention comprises a nursery basket having a holding portion for holding a seeding material, and a nutrient solution for surrounding a side surface and a bottom surface of the nursery basket and holding a nutrient solution. A holding tank is provided, and the nutrient solution holding tank is provided with an outside air intake hole formed in a structure for blocking outside light.

[0008]

[Action]

 According to the present invention, the nutrient solution holding tank is arranged around the nursery basket and the side and bottom of the nursery basket are surrounded by the nutrient solution holding tank, so that the nutrient solution necessary for growing the seedlings is stored in the nutrient solution holding tank. In addition to retaining water, the nutrient solution storage tank limits the range of seedling root spread. Also, by regularly supplying the liquid, the nutrient solution in the nutrient solution holding tank is drained from the outside air intake hole to circulate the nutrient solution in the nutrient solution holding tank, and the outside air is structured to block the external light. The outside air is taken in through the intake holes to prevent root rot of the root without hindering the growth of the root.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an embodiment of the present invention. In the figure, B is a seedling pot for hydroponic culture, which is composed of a nutrient solution holding tank 1 and a seedling basket 2. The nutrient solution holding tank 1 is one size larger than the nursery basket 2 and is formed in a container shape with an open upper surface of a truncated truncated quadrangular pyramid so as to surround the side and bottom of the nursery basket 2. As shown in FIGS. 2 and 3, the nutrient solution holding tank 1 has a slightly inner center portion on the side plates 1a to 1d facing the upper end of the water retaining section 3 which retains the nutrient solution necessary for growing seedlings in the inner lower part thereof. An outside air intake hole 4 is provided from the upper part toward the outer center and slightly lower part. Here, the angle of the outside air intake hole 4 is selected to be an angle capable of preventing the outside light from entering when the seedling raising basket 2 is inserted and keeping the inside of the nutrient solution storage tank 1 in a dark room state. Has been done. In addition, the nutrient solution holding tank 1 has a size such that the spread range of the grown seedling roots fits into the planting holes arranged in the bed dedicated to planting.

The seedling raising basket 2 has the same structure as that of the conventional seedling raising basket, and as shown in FIGS. 4 and 5, the inverted truncated quadrangular pyramid whose top surface is smaller than the top surface is opened. It is composed of a car body 2a and an upper lid 6 which is fitted into the upper surface of the car body 2a, and the side surface and the bottom surface of the car body 2a are formed in a lattice shape. A recess 6a is formed in the center of the upper lid 6, and a fitting hole 5 for holding a seeding material 7 such as a sponge seeded is bored in the bottom of the recess 6a. The nursery basket 2 has a size that does not hinder the growth of the roots of the seedlings and can fit in the nutrient solution storage tank 1.

When raising seedlings in the seedling pot B for hydroponics of the above-mentioned example, the seedling raising basket 2 holding the seeding material 7 such as a sponged seed in the fitting hole 5 is stored in the nutrient solution holding tank 1. Then, the nutrient solution is regularly supplied from the fitting hole 5. The supplied nutrient solution is retained in the water retaining section 3, and the excessively added nutrient solution is drained to the outside through the outside air intake hole 4. The nutrient solution in the water retaining section 3 is exchanged by this regular supply, and the outside air is taken into the nutrient solution holding tank 1 through the outside air intake hole 4 so that the oxygen in the outside air is not immersed in the nutrient solution. The root rot of the seedling root can be prevented by absorbing it from a part of it. Further, since the outside air intake hole 4 is provided so as to block outside light from the upper inside to the lower outside of the nutrient solution holding tank 1, the inside of the nutrient solution holding tank can be kept in a dark room state. The penetration of light does not hinder the growth of seedling roots. Further, the seedling root is restricted from spreading to the outside by the nutrient solution holding tank 1.

When the seedlings grow and are planted, the seedlings are taken out from the nursery basket 2 and transplanted into the planting holes of the dedicated planting bed. Therefore, according to the above-mentioned embodiment, since the spread of the seedling root is limited to the size corresponding to the settling hole of the dedicated planting bed by the nutrient solution holding tank 1, the seedling root is settling hole of the dedicated planting bed at the time of planting. The seedling roots are isolated for each seedling, so that the roots do not get entangled with other seedling roots and transplanting is easy.

In addition, at the time of raising seedlings, it is possible to perform hydroponic cultivation in a seedling raising pot alone without using a dedicated seedling raising bed, so that an arbitrary number of seedlings can be raised in any place other than the dedicated seedling raising bed. Therefore, by raising the seedlings according to the use status of the dedicated planting bed, the dedicated planting bed can be efficiently used and the operating rate of the hydroponic equipment can be significantly improved.

In the above embodiment, the nutrient solution holding tank 1 and the seedling raising basket 2 have a truncated truncated quadrangular pyramid shape, but the present invention is not limited to this, and a truncated truncated cone shape, a cylindrical shape, and a polygonal tubular shape. Any shape such as the above can be adopted, and the point is that the shape can easily take out the seedling root.

[0015]

[Effect of device]

 As described above, according to the present invention, by disposing the nutrient solution storage tank around the nursery basket holding the seeding material, it is possible to limit the spreading range of the seedling root to an arbitrary range, and to set the planting. It can be done easily. Also, by periodically supplying the liquid, the nutrient solution in the nutrient solution holding tank is drained from the outside air intake hole to circulate the nutrient solution in the nutrient solution holding tank, and the outside air is supplied to the seedling root from the outside air intake hole. By doing so, the effect of preventing root rot and facilitating hydroponics can be obtained.
